Velocity与Jsp、Freemarker的对比

在java领域，表现层技术主要有三种：jsp、freemarker、velocity。macro可以用于实现自定义指令,通过使用自定义指令,可以将一段模板片段定义成一个用户指令,使用macro指令的语法格式如下:
< #macro name param1 param2 ... paramN>

<#compress>
...
< /#compress>
用来压缩空白空间和空白的行

<#macro path>

<#compress>

${request.contextPath}

</#compress>

</#macro>

在引用时是<@path/>

<#compress>

var path_="<@path/>";

var user = "${(visitor.name)!''}";

</script>

</#compress>

</#macro>

<#macro Select id name optList optValue showAll=false>

<#if showAll>

全部

</option>

</#if>

<#list optList as opt>

<option value="${(opt.id)!}"

<#if (optValue==opt.id)>selected</#if>

${(opt.name)!}

</option>

</#list>

</select>

</#macro>

<#macro FormSelect id name optType optValue showAll=false>

<#list DtCache?keys as key>

<#if key==optType>

<#assign optList=DtCache[key] >

<@Select id name optList optValue showAll />

</#if>

</#list>

</#macro>

<@Select id="companyName" name="companyName" optList=companyList optValue="" showAll=true/>

<@FormSelect id="devType" name="devType" optType="DevType" optValue="" showAll=true />

　　设置为float的div在ie下设置的margin会加倍。这是一个ie6都存在的bug。解决方案是在这个div里面加上display:inline;

#imfloat{
　　float:left;
　　margin:5px;
　　display:inline;}

clear{ clear:both;}

高度不能自适应是当内层对象的高度发生变化时外层高度不能自动进行调节，特别是当内层对象使用margin 或paddign 时。

　　例：

　　#box {background-color:#eee; }
　　#box p {margin-top: 20px;margin-bottom: 20px; text-align:center; }
　　<div id="box">
　　<p>p对象中的内容＜/p>
　　</div>

　　解决技巧：在P对象上下各加2个空的div对象CSS代码：.1{height:0px;overflow:hidden;}或者为DIV加上border属性。

Handler消息传递机制浅析

很多时候我们做界面刷新都需要通过Handler来通知UI组件更新！

1.学习路线图：

2.Handler类的引入:

3.Handler的执行流程图：

流程图解析: 相关名词

· UI线程:就是我们的主线程,系统在创建UI线程的时候会初始化一个Looper对象,同时也会创建一个与其关联的MessageQueue;

· Handler:作用就是发送与处理信息,如果希望Handler正常工作,在当前线程中要有一个Looper对象

· Message:Handler接收与处理的消息对象

· MessageQueue:消息队列,先进先出管理Message,在初始化Looper对象时会创建一个与之关联的MessageQueue;

· Looper:每个线程只能够有一个Looper,管理MessageQueue,不断地从中取出Message分发给对应的Handler处理！

当我们的子线程想修改Activity中的UI组件时,我们可以新建一个Handler对象,通过这个对象向主线程发送信息;而我们发送的信息会先到主线程的MessageQueue进行等待,由Looper按先入先出顺序取出,再根据message对象的what属性分发给对应的Handler进行处理！

Handler写在主线程中

MainActivity.java：

public class MainActivity extends Activity { //定义切换的图片的数组id int imgids[] = new int[]{ R.drawable.s_1, R.drawable.s_2,R.drawable.s_3, R.drawable.s_4,R.drawable.s_5,R.drawable.s_6, R.drawable.s_7,R.drawable.s_8 }; int imgstart = 0; final Handler myHandler = new Handler() { @Override //重写handleMessage方法,根据msg中what的值判断是否执行后续操作 public void handleMessage(Message msg) { if(msg.what == 0x123) { imgchange.setImageResource(imgids[imgstart++ % 8]); } } }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); final ImageView imgchange = (ImageView) findViewById(R.id.imgchange); //使用定时器,每隔200毫秒让handler发送一个空信息 new Timer().schedule(new TimerTask() { @Override public void run() { myHandler.sendEmptyMessage(0x123); } }, 0,200); } }

Handler写在子线程中

如果是Handler写在了子线程中的话,我们就需要自己创建一个Looper对象了!创建的流程如下:

1 )直接调用Looper.prepare()方法即可为当前线程创建Looper对象,而它的构造器会创建配套的MessageQueue; 2 )创建Handler对象,重写handleMessage( )方法就可以处理来自于其他线程的信息了! 3 )调用Looper.loop()方法启动Looper

使用示例：输入一个数，计算后通过Toast输出在这个范围内的所有质数

实现代码： main.xml：

MainActivity.java:

public class CalPrime extends Activity { static final String UPPER_NUM = "upper"; EditText etNum; CalThread calThread; // 定义一个线程类 class CalThread extends Thread { public Handler mHandler; public void run() { Looper.prepare(); mHandler = new Handler() { // 定义处理消息的方法 @Override public void handleMessage(Message msg) { if(msg.what == 0x123) { int upper = msg.getData().getInt(UPPER_NUM); List<Integer> nums = new ArrayList<Integer>(); // 计算从2开始、到upper的所有质数 outer: for (int i = 2 ; i <= upper ; i++) { // 用i处于从2开始、到i的平方根的所有数 for (int j = 2 ; j <= Math.sqrt(i) ; j++) { // 如果可以整除，表明这个数不是质数 if(i != 2 && i % j == 0) { continue outer; } } nums.add(i); } // 使用Toast显示统计出来的所有质数 Toast.makeText(CalPrime.this , nums.toString() , Toast.LENGTH_LONG).show(); } } }; Looper.loop(); } } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); etNum = (EditText)findViewById(R.id.etNum); calThread = new CalThread(); // 启动新线程 calThread.start(); } // 为按钮的点击事件提供事件处理函数 public void cal(View source) { // 创建消息 Message msg = new Message(); msg.what = 0x123; Bundle bundle = new Bundle(); bundle.putInt(UPPER_NUM , Integer.parseInt(etNum.getText().toString())); msg.setData(bundle); // 向新线程中的Handler发送消息 calThread.mHandler.sendMessage(msg); } }

Fragment基本概述

Fragment是Android3.0后引入的一个新的API，他出现的初衷是为了适应大屏幕的平板电脑，当然现在他仍然是平板APP UI设计的宠儿，而且我们普通手机开发也会加入这个Fragment，我们可以把他看成一个小型的Activity，又称Activity片段！想想，如果一个很大的界面，我们就一个布局，写起界面来会有多麻烦，而且如果组件多的话是管理起来也很麻烦！而使用Fragment 我们可以把屏幕划分成几块，然后进行分组，进行一个模块化的管理！从而可以更加方便的在运行过程中动态地更新Activity的用户界面！另外Fragment并不能单独使用，他需要嵌套在Activity 中使用，尽管他拥有自己的生命周期，但是还是会受到宿主Activity的生命周期的影响，比如Activity 被destory销毁了，他也会跟着销毁！

ant安装、环境变量配置及验证

一、安装ant

到官方主页http://ant.apache.org下载新版（目前为Ant1.8.1）的ant，得到的是一个apache-ant-1.8.1-bin.zip的压缩包。将其解压到你的硬盘上，例如：C:\apache-ant-1.8.1。

二、配置环境变量

window中设置ant环境变量：

ANT_HOME C:/ apache-ant-1.8.1

path C:/ apache-ant-1.8.1/bin

classpath C:/apache-ant-1.8.1/lib

注意：【

　　配置环境变量：我的电脑----属性-----高级----环境变量
如：ANT_HOME：C:\apache-ant-1.8.1
PATH：%ANT_HOME%\bin （为了方便在dos环境下操作）

实验了总是失败，没办法换成地址 C:/ apache-ant-1.8.1/bin，而不再使用变量。。。成功了。。

】

三、验证ant

为了验证ant是否成功安装，可以进行如下操作：

依次选择：开始->运行->cmd，输入如下命令：ant

如果出现如下内容，说明安装成功：

Buildfile: build.xml does not exist!

Build failed

【说明ant安装成功！因为ant默认运行build.xml文件，这个文件需要我们建立。】

查看版本：ant -version

但如果出现如下内容，说明安装失败：（可以重复前述步骤，直至安装成功。）

'ant' 不是内部或外部命令，也不是可运行的程序或批处理文件。

从别处移动过来的：

使用：
(1)在D盘根目录下建立build.xml

1<?xml version="1.0" encoding="GBK"?>
2<project name="测试脚本" default="copyfile" basedir="." >
3   <target name="copyfile">
4      <copy file="d:/a.txt" todir="e:/Temp" overwrite="true" />
5   </target>
6</project>

（2）在D盘根目录下建立文件a.txt。
（3）进入dos，
         d:
         ant

         此时可在E:/Temp目录下见到文件aa.txt，内容与a.txt一样，即拷贝成功！

Cd\进入根目录

Cd d:aa锁定d盘下的aa文件夹

D:则直接进入d盘下的aa文件夹

sql语句如何查询不重复记录

如果只使用select distinct [name] from [table]的话后面就不能加order by [score]了

select name,score from tablename group by name,score order by score;

select distinct COMMUNITY_NAME from res_community where COMMUNITY_NAME!=''

出现空的话，xml解析数据会出错

SQL2000里的数据类型为datetime默认值getdate()

mysql建表语句里把字段default now()?? 这个是不行的，now是在你insert或者update时候写入的，比如： insert into 表 (字段) values (now());

kcontext.setVariable("setInCode",inCode);将inCode赋值给流程变量setInCode,后面的节点使用input data mapping引用setInCode

//hql

StringBuffer hql = new StringBuffer();

hql.append("select new com.eshine.ump.repo.bo.RepoIn(b.repoName,a.matName")

.append(",a.matModel,a.matUnit,a.inNum,b.inTime,b.inMan,b.inType)")

.append("from RepoInMaterail a,RepoInLog b ")

.append("where a.id.inCode = b.inCode");

//查询条件

StringBuffer params = new StringBuffer();

String matName = form.get("matName");

if(matName !=null && !"".equals(matName)){

params.append(" and a.matName = '" + matName + "'");

}

String repoName = form.get("repoName");

if(repoName !=null && !"".equals(repoName)){

params.append(" and b.repoName = '" + repoName + "'");

}

//查询

if(params.toString().length()==0){

//查询相同入库编号的记录

Pager p = new Pager();

return this.pageByHqls(hql.toString(), p, null);

}else{

//根据条件查询

hql.append(params);

Pager p = new Pager();

return this.pageByHqls(hql.toString(), p, null);

关于安卓开发时，调用扫描二维码的功能时，代码的理解

分享| 2015-02-04 08:54灬奈丶何氵 | 浏览 783 次

AppAndroid移动开发

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.setAction("com.google.zxing.client.android.SCAN");
intent.setClassName("com.google.zxing.client.android", "com.google.zxing.client.android.CaptureActivity");
startActivityForResult(intent, 0);
}
这段代码的括号内的代码的意思是什么？现在我主要看不懂的是最后一行的startActivityForResult(intent, 0);这行的作用和意思是什么？

2015-02-04 09:33提问者采纳

最后一行和startActivity区别是
在这个activity里面会重写这个方法onActivityResult（int requestCode, int resultCode, Intent data）；当跳转到CaptureActivity后执行可以返回给上面你提供代码的activity数据通过setResult( int resultCode, data); 来传递。有点类似回调、
里面的0就是重写方法里面的第一个参数用来判断的作用。

1.解析简单的josn格式字符串

String msg = "{'rs':0,'fs':'登录成功!'}";

JSONObject jsonObject = new JSONObject(msg);

System.out.println(jsonObject.getString("fs"))

1. List receiveList = offDao.findByHql(hql, page, row);

2. if(receiveList.size()>0&&receiveList!=null){

3. Iterator it = receiveList.iterator();

4. while(it.hasNext()){

5. Object[] object = (Object[])it.next();

6. OffAnnouncementReceive offReceive = new OffAnnouncementReceive();

7. String consigneeid=object[0].toString();

8. String flgs = object[1].toString();

9. String sendmail = object[2].toString();

10. String sendPeo = object[4].toString();

11. Date sendDate = (Date)object[5];

12. String announcementReceiveId = object[6].toString();

13. offReceive.setAnnouncementReceiveId(announcementReceiveId);

14. offReceive.setConsigneeId(consigneeid);

15. offReceive.setSendmailId(sendmail);

16. if(sendDate!=null&&!sendDate.equals("")){

17. offReceive.setSendDate(sdf.format(sendDate));

18. }

19. }

20. }

使用sql返回的list<Object>转成需要的实体对象，看下面的Map的使用,很方便（需要将Query对象setResultTransformer）：

[java] view plain copy

1. List list = session.createSQLQuery(sql)

2. .setResultTransformer(

3. Transformers.ALIAS_TO_ENTITY_MAP)

4. .list();

5. //此时，每个Object可以转换成一个Map

6. Map map = (Map) list.get(i);

7. map.get("student_id"); //这里的key 一定是数据库对应的字段名才行

做项目的时候遇到这样的问题，hibernate执行SQL语句返回来的list集合调试断点的时候检查list集合有值，但是返回action遍历的时候在list.get(i);这句话时报异常，调试结果是list集合为空，查找到的结果就是用SQL语句不能自动转换成bean对象，所以要转换成数组形式在进行遍历，这时返回的list集合里的值就可以遍历出来了.

偷个懒把别人的代码粘过来了，还有个错误没有写，有时间在总结吧：

Hibernate执行sql语句

Hibernate执行sql语句：
BasicServiceImpl basicServiceImpl = new BasicServiceImpl();
String hql = "select * from AccountInfo where selfId='0000100003' or(left(selfId,10)='0000100004' and
nodeSum=0)";

*写SQL语句的时候做好给表名起个别名

TManager tManager = TManagerImpl.getInstance();
List accountList = tManager.getSession().createSQLQuery(hql).list();
//List accountList = tManager.getSession().createSQLQuery(hql).addEntity(AccountInfo.class).list();
for(int i=0;i<accountList.size();i++){
Object[] objects = (Object[])accountList.get(i);
for(int j=0;j<objects.length;j++){
System.out.println(objects[j].getClass().getName());// 从这个输出结果可以看出，objects[j]的
值实际上是AccountInfo的属性（表的字段）而不是AccountInfo对象，
}
System.out.println(objects.length);
}
信息: java.lang.ClassCastException:Ljava.lang.Object; cannot be cast to net.yjiasoft.sss.table.AccountInfo
分析：原来是查询出来的字段并不能自动转换为bean对象，所以要添加addEntity(Clazz class)。
扩展：
1.SQL返回一个Map对象，也就是说在在list里包含多个Map，代码如下
Query query = session.createSQLQuery("select id,name from Tree t where pid in (select id from Tree) ").setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP); //返回一个map,KEY:为DB中名称一致（大小写一致）遍历list时就可以
Map map = (Map)list.get[i];
map.get("id");map.get("name");来取值。按你的SQL语句select后的字段名来作为map的Key，但这个key必须与数据库中的字段名一模一样。
2.可以用作函数方面的。如
Query query = session.createSQLQuery("select sum(id) SUMID from Tree t where pid in (select id from Tree)
.addScalar("SUMID",Hibernate.INTEGER) //转换类型，按DB中的type转
.setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP); //返回一个map,KEY:为DB中名称一致（大小写一致）
直接就map.get("SUMID")可以取值了
还有一点就是这个方法在Hibernate3.2版本上才能正常运行。
3.hibernate 中createQuery与createSQLQuery两者区别是：
前者用的hql语句进行查询，后者可以用sql语句查询
前者以hibernate生成的Bean为对象装入list返回
后者则是以对象数组进行存储
所以使用createSQLQuery有时候也想以hibernate生成的Bean为对象装入list返回，就不是很方便
突然发现createSQLQuery有这样一个方法可以直接转换对象
Query query = session.createSQLQuery(sql).addEntity(XXXXXXX.class);
XXXXXXX 代表以hibernate生成的Bean的对象，也就是数据表映射出的Bean。
呵呵以后多注意，还是时不时的要看看hibernate各个对象方法的使用。
还有另外一个相关的小细节应注意：
比如有这样一个po
PO: User.class
properties: userId,userName
DDL: create table tuser (userid varchar(10),username varchar(20));
当执行：
session.createQuery("from User u").list()时生成的SQL：
select userid,username from tuser;
当执行：
session.createQuery("from User u").iterator()时生成的SQL：
select userid from tuser;
可以看出list()一次将数据从数据库中读出直接填充到List中
iterator()将数据的主键从数据库中读出，当循环这个Iterator时才添加执行：
select userid,username from user where userid=?;把数据读出。
在不同的应用范围使用不同的方法，具体在hibernate应用中应当注意。

select * from " + tableName + " where 1=0

用于查看表结构，而不读取数据记录

public boolean isTableCreate(String tableName) {

try {

String sql = "select * from " + tableName + " where 1=0";

jdbcDao.queryForList(sql);

return true;

} catch (Exception e) {

return false;

}

JAVA发送手机短信,流传有几种方法:(1)使用webservice接口发送手机短信,这个可以使用sina提供的webservice进行发送,但是需要进行注册;(2)使用短信mao的方式进行短信的发送,这种方式应该是比较的常用,前提是需要购买硬件设备,呵呵(3)使用中国网建提供的SMS短信平台（申请账号地址：http://sms.webchinese.cn/default.shtml）

本程序主要是运用了中国网建提供的SMS短信平台，这个短信平台基于java提供个专门的接口

三个jar包：

commons-codec-1.4

commons-httpclient-3.1

commons-logging-1.1.1

请自行下载，呵呵

GBK编码发送接口地址：
http://gbk.sms.webchinese.cn/?Uid=本站用户名&Key=接口安全密码&smsMob=手机号码&smsText=短信内容
UTF-8编码发送接口地址：
http://utf8.sms.webchinese.cn/?Uid=本站用户名&Key=接口安全密码&smsMob=手机号码&smsText=短信内容
获取短信数量接口地址(UTF8)：
http://sms.webchinese.cn/web_api/SMS/?Action=SMS_Num&Uid=本站用户名&Key=接口安全密码
获取短信数量接口地址(GBK)：

mysql查询前一个月的问题

select * from table where date_column between '2011-07' and DATE_ADD('2011-07',INTERVAL 1 MONTH)

查询一天： select * from table where to_days(column_time) = to_days(now()); select * from table where date(column_time) = curdate(); 查询一周： select * from table where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(column_time); 查询一个月： select * from table where DATE_SUB(CURDATE(), INTERVAL INTERVAL 1 MONTH) <= date(column_time);

Js定时器

1.倒计定时器：timename=setTimeout("function();",delaytime);

2..循环定时器：timename=setInterval("function();",delaytime);

3.用clearTimeout(timename) 来关闭倒计时定时器，而用clearInterval(timename)来关闭循环定时器。

网站大并发解决方案

使用高性能的服务器、高性能的数据库、高效率的编程语言、还有高性能的Web容器。

小成本方法：

1、HTML静态化

1. 将部分内容进行后台更新的时候进行静态化，这样避免了大量的数据库访问请求。当我们每次更新了数据库中的相应信息以后，我们便可以重新执行这个方法，将这个页面重新静态化，当我们每次访问这个网页的时候便不会每一次都去数据库中查询数据了，而是访问的一个已经一次性生成了的静态页面，这也就达到了提高网站运行速度的目标。 //防止浏览器缓存，用于重新生成新的html

2. UUID uuid = UUID.randomUUID();

3. Writer out = new OutputStreamWriter(new FileOutputStream(dirPath+"/"+uuid+indexFileName),"UTF-8");

4. ProcessClient.processBody(out);

5. response.sendRedirect("templates/html/"+uuid+"index.html");

2、图片服务器分离

3、数据库集群和库表散列

负载均衡 1：如何实现多应用服务器间的session共享：（一台服务器崩溃，另外一台服务器可以继续支持）

2：如何分发请求到各个应用服务器实现压力分解：（这里的解决方案是用apache做 web服务器）

tomcat内存的设置：1.4GBJVM+256MB的池

[java] view plain copy

1. set JAVA_HOME=C:\JAVA\JDK15

2. set CATALINA_OPTS=-server -Xms 1400m -Xmx1400m -XX:PermSize=256m -XX:MaxPermSize=256m

tomcat线程的设置：初始产生1000线程数最大支持2000线程

[java] view plain copy

1. <Connector port="80" maxHttpHeaderSize="8192"

2. maxThreads="4000" minSpareThreads="1000" maxSpareThreads="2000"

3. enableLookups="false" redirectPort="8443" acceptCount="2000"

4. connectionTimeout="20000" disableUploadTimeout="true" />

Java泛型中的标记符含义：

E - Element (在集合中使用，因为集合中存放的是元素)

T - Type（Java 类）

K - Key（键）

V - Value（值）

N - Number（数值类型）

？ - 表示不确定的java类型

S、U、V -2nd、3rd、4th types

为java配置本地环境变量，并测试java环境是否配置成功。

#vi /etc/profile

JAVA_HOME=/usr/local/java

JRE_HOME=/usr/local/java/jre

Linux下Tomcat的安装配置

一.下载安装对应的jdk,并配置Java环境。

官网下载地址：

http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u26-download-400750.html

下载将jdk加压后放到/usr/local目录下：

[root@master ~]#chmod 755 jdk-6u5-linux-x64.bin

[root@master ~]# ./jdk-6u5-linux-x64.bin

[root@master ~]#mv jdk1.6.0_05 /usr/local

建立/usr/local/下的jdk软连接方便以后版本升级：

[root@master ~]# ln -s /usr/local/jdk1.6.0_05/ /usr/local/jdk

配置环境变量：

在 /etc/profile 中加入以下内容：

JAVA_HOME=/usr/local/jdk1.6.0_05

JAVA_BIN=/usr/local/jdk1.6.0_05/bin

PATH=$PATH:$JAVA_BIN

CLASSPATH=$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export JAVA_HOME JAVA_BIN PATH CLASSPATH

保存退出

[root@master ~]source /etc/profile

查看java环境变量是否生效

[root@master ~]# java -version

java version "1.6.0_05"

Java(TM) SE Runtime Environment (build 1.6.0_05-b13)

Java HotSpot(TM) 64-Bit Server VM (build 10.0-b19, mixed mode)

测试成功

二．下载安装tomcat（http://tomcat.apache.org/）

[root@master ~]# unzip apache-tomcat-6.0.30.zip

[root@master ~]# mv apache-tomcat-6.0.30/ /usr/local/

[root@master ~]cd /usr/local/

[root@master local]# ln -s /usr/local/apache-tomcat-6.0.30/ /usr/local/tomcat

[root@master local]# cd tomcat/bin/

[root@master bin]#ls

[root@master bin]#vim catalina.sh

添加以下内容：

CATALINA_HOME=/usr/local/apache-tomcat-6.0.30/

[root@master local]#chmod +x *.sh

三．启动tomcat服务器

[root@master tomcat]# /usr/local/tomcat /bin/catalina.sh start

Using CATALINA_BASE: /usr/local/apache-tomcat-6.0.30/

Using CATALINA_HOME: /usr/local/apache-tomcat-6.0.30/

Using CATALINA_TMPDIR: /usr/local/apache-tomcat-6.0.30//temp

Using JRE_HOME: /usr/local/jdk1.6.0_05

Using CLASSPATH: /usr/local/apache-tomcat-6.0.30//bin/bootstrap.jar

[root@master logs]# cd /usr/local/tomcat/logs/

[root@master logs]# tail -f catalina.out

at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)

at java.lang.reflect.Method.invoke(Method.java:597)

at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:289)

at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:414)

Jul 4, 2011 11:06:57 AM org.apache.coyote.http11.Http11Protocol pause

INFO: Pausing Coyote HTTP/1.1 on http-8080

Jul 4, 2011 11:06:58 AM org.apache.catalina.core.StandardService stop

INFO: Stopping service Catalina

Jul 4, 2011 11:06:58 AM org.apache.coyote.http11.Http11Protocol destroy

INFO: Stopping Coyote HTTP/1.1 on http-8080

四．在浏览器中输入

http://localhost:8080/（如果不是本机，则输入对应的ip地址）

测试出现tomcat页面则测试成功

ps：需要说明的是tomcat的默认测试页面是放在webapps下面，这个其实是在server.xml文件中配置的，如下所示：

[root@SOR_SYS apache-tomcat-6.0.30]# ls
LICENSE NOTICE RELEASE-NOTES RUNNING.txt bin conf lib logs temp webapps work

1)webapps文件夹主要用于web应用程序部署，比如你可以把你的应用程序包，如war文件拷到该目录下，容器会自动部署。
　　2)conf文件夹下主要是放置tomcat的服务器的相关配置文件

五。添加应用，再次进行测试

在webapps目录下放测试包（注意：webaapps目录下面主要是放应用包的.war在tomcat重启访问后会自动解压）

[root@master webapps]# pwd
/usr/local/tomcat/webapps

[root@master webapps]# tar -zxvf moni2.tar.gz

[root@master webapps]# ls
docs examples host-manager manager moni2 moni2.tar.gz ROOT

[root@master webapps]# /usr/local/tomcat/bin/catalina.sh start（重启tomcat）
Using CATALINA_BASE:   /usr/local/apache-tomcat-6.0.30/
Using CATALINA_HOME:   /usr/local/apache-tomcat-6.0.30/
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-6.0.30//temp
Using JRE_HOME:        /usr/local/jdk1.6.0_05
Using CLASSPATH:       /usr/local/apache-tomcat-6.0.30//bin/bootstrap.jar

在浏览器中输入如下地址：

http://192.168.55.229:8080/moni2/

六。修改tomcat的监听端口

[root@master ~]# cd /usr/local/tomcat/conf

[root@master ~]# ls

[root@master ~]# vim server.xml

<Server port="8005" shutdown="SHUTDOWN">【停止tomcat时的端口】

<Connector port="8081" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" /> 【tomcat默认的监听端口是8080，现在改成8081】

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />【apache+tomcat模式时访问tomcat的端口】

现在重启tomcat。访问http://192.168.55.229:8081/moni2/【注意：这时就需要修改端口了，嘿嘿。。。】

(1)load(InputStream inStream)

　　这个方法可以从.properties属性文件对应的文件输入流中，加载属性列表到Properties类对象。如下面的代码：

Properties pro = new Properties();FileInputStream in = new FileInputStream("a.properties");pro.load(in);in.close();

(2)store(OutputStream out, String comments)

这个方法将Properties类对象的属性列表保存到输出流中。如下面的代码：

FileOutputStream oFile = new FileOutputStream(file, "a.properties");pro.store(oFile, "Comment");oFile.close();

public static Properties loadProperty(String propFileName) {

InputStream inputStream = PropertiesUtil.class.getResourceAsStream("/"

+ propFileName);

Properties properties = new Properties();

try {

properties.load(inputStream);

} catch (IOException e) {

e.printStackTrace();

} finally {

if (inputStream != null)

try {

inputStream.close();

} catch (IOException e) {

e.printStackTrace();

}

return properties;

}

Java GC:修改eclipse.ini文件参数。

Eclipse dropins文件夹放插件。

使用自定义标签函数<%@ taglib prefix="fns" uri="/WEB-INF/tlds/fns.tld" %>

<description>获取当前用户的菜单对象列表</description>

<name>getMenuList</name>

<function-class>com.yida.modules.sys.utils.UserUtils</function-class>

<function-signature>java.util.List getMenuList()</function-signature>

<example>${fns:getMenuList()}</example>

</function>

使用SHIRO的步骤： 1，导入jar 2，配置web.xml 3，建立dbRelm 4，在Spring中配置

@Service @Transactional public class MyShiro extends AuthorizingRealm{ @Inject private UserService userService; /** * 权限认证 */ @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { //获取登录时输入的用户名 String loginName=(String) principalCollection.fromRealm(getName()).iterator().next(); //到数据库查是否有此对象 User user=userService.findByName(loginName); if(user!=null){ //权限信息对象info,用来存放查出的用户的所有的角色（role）及权限（permission） SimpleAuthorizationInfo info=new SimpleAuthorizationInfo(); //用户的角色集合 info.setRoles(user.getRolesName()); //用户的角色对应的所有权限，如果只使用角色定义访问权限，下面的四行可以不要 List<Role> roleList=user.getRoleList(); for (Role role : roleList) { info.addStringPermissions(role.getPermissionsName()); } return info; } return null; } /** * 登录认证; */ @Override protected AuthenticationInfo doGetAuthenticationInfo( AuthenticationToken authenticationToken) throws AuthenticationException { //UsernamePasswordToken对象用来存放提交的登录信息 UsernamePasswordToken token=(UsernamePasswordToken) authenticationToken; //查出是否有此用户 User user=userService.findByName(token.getUsername()); if(user!=null){ //若存在，将此用户存放到登录认证info中 return new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), getName()); } return null;

1、使用注解@AspectJ定义切面

applicationcontext.xml里加入

AOP的XML命名空间和声明相关schema
命名空间:
xmlns:aop="http://www.springframework.org/schema/aop"
schema声明:
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-2.0.xsd

加入<aop:aspectj-autoproxy />标签
@Aspect
@Service
@Order(1)
public class HttpAspect {
private static final org.apache.log4j.Logger logger = org.apache.log4j.Logger
.getLogger(HttpAspect.class);
public static final String Http_RequestIdentifier = "requestIdentifier";
//用于累加周期
private static long start = 0L;
private static long end = 0L; //控制时钟周期
private static final long invet = 1000L*60*60L;
private static int callTimes = 0;

java中的==是用来判断对象所使用的内存地址是不是同一个，进而判断是不是同一个对象。例如 objA == objB
注意这里是同一个对象才会是true，如果不是同一个对象，哪怕两个对象所有属性都相同也会返回false。

而equals则是一个方法，你可以为自己的类编写equals方法来判断是不是相等。这里String类就提供了equals方法来判断两个String对象是不是相同，而不是去判断两个String对象是不是同一个对象，因为我们一般使用中，只关心两个字符串内容相同与否，而不会关心是不是同一个对象。

HttpClient client = new HttpClient();///创建HttpClient实例
HttpMethod method = new GetMethod(url);//创建请求连接方法的实例
method.setRequestHeader( "Content-Type", "text/html;charset=utf-8" );
client.executeMethod( method );//用HttpClient实例的execute方法来执行第二步中创建好的 method 实例
System.out.println( method.getStatusLine() );// 打印服务器返回的状态
取得目标地址的内容有三种方法：
第一种，getResponseBody，该方法返回的是目标的二进制的byte流；
第二种，getResponseBodyAsString，这个方法返回的是String类型，值得注意的是该方法返回的String的编码是根据系统默认的编码方式，所以返回的String值可能编码类型有误，在本文的"字符编码"部分中将对此做详细介绍；
第三种，getResponseBodyAsStream，这个方法对于目标地址中有大量数据需要传输是最佳的。在这里我们使用了最简单的
InputStream inputStream=method.getResponseBodyAsStream();
ByteArrayOutputStream output = new ByteArrayOutputStream();
byte[] buffer = new byte[4096];
int n = 0;
while (-1 != (n = inputStream.read(buffer))) {
output.write(buffer, 0, n);
}
byte[] body = output.toByteArray();
// 打印返回的信息
String aString=new String(body, "utf-8" );
//返回数据
System.out.println("接口返回信息:"+aString);
JSONObject jobj =JSONObject.fromObject(aString);
//查询成功
String success=jobj.optString("success");
//返回状态码
String msg=jobj.optString("msg");
//异常信息
String errInfo=jobj.optString("errInfo");

JavaScript encodeURI() 函数可把字符串作为 URI 进行编码
JavaScript decodeURI() 函数对 encodeURI() 函数编码过的 URI 进行解码。
要进行两次转码才不会出现乱码(默认为UTF-8)
encodeURI(encodeURI(http://localhost/qq/index.jsp?title=专业));
java接收参数代码：
String title = request.getParameter("title");

title = URLDecoder.decode(title, "UTF-8");
