3 spring和mybatis整合

新建config.properties文件,主要是配置mysql数据库链接，内容如下

driver=com.mysql.jdbc.Driver  jdbc_url=jdbc\:mysql\://localhost\:3306/sy?useUnicode\=true&characterEncoding\=UTF-8&zeroDateTimeBehavior\=convertToNull jdbc_username=root  ${jdbc_password}=root  validationQuery=SELECT 1

4 新建spring-mybatis.xml文件，整合spring和mybatis，内容如下

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"><!-- 自动扫描(自动注入) --><context:component-scan base-package="wxd.service" /><!-- JNDI方式配置数据源 --><!-- <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName" value="${jndiName}"></property> </bean> --><!-- 配置数据源 --><bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"><property name="url" value="${jdbc_url}" /><property name="username" value="${jdbc_username}" /><property name="password" value="${jdbc_password}" /><!-- 初始化连接大小 --><property name="initialSize" value="0" /><!-- 连接池最大使用连接数量 --><property name="maxActive" value="20" /><!-- 连接池最大空闲 --><property name="maxIdle" value="20" /><!-- 连接池最小空闲 --><property name="minIdle" value="0" /><!-- 获取连接最大等待时间 --><property name="maxWait" value="60000" /><!-- <property name="poolPreparedStatements" value="true" /> <property name="maxPoolPreparedStatementPerConnectionSize" value="33" /> --><property name="validationQuery" value="${validationQuery}" /><property name="testOnBorrow" value="false" /><property name="testOnReturn" value="false" /><property name="testWhileIdle" value="true" /><!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 --><property name="timeBetweenEvictionRunsMillis" value="60000" /><!-- 配置一个连接在池中最小生存的时间，单位是毫秒 --><property name="minEvictableIdleTimeMillis" value="25200000" /><!-- 打开removeAbandoned功能 --><property name="removeAbandoned" value="true" /><!-- 1800秒，也就是30分钟 --><property name="removeAbandonedTimeout" value="1800" /><!-- 关闭abanded连接时输出错误日志 --><property name="logAbandoned" value="true" /><!-- 监控数据库 --><!-- <property name="filters" value="stat" /> --><property name="filters" value="mergeStat" /></bean><!-- myBatis文件 --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource" /><!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 --><property name="mapperLocations" value="classpath:wxd/mapping/*.xml" /></bean><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="wxd.dao" /><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /></bean><!-- 配置事务管理器 --><bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource" /></bean><!-- 注解方式配置事物 --><!-- <tx:annotation-driven transaction-manager="transactionManager" /> --><!-- 拦截器方式配置事物 --><tx:advice id="transactionAdvice" transaction-manager="transactionManager"><tx:attributes><tx:method name="add*" propagation="REQUIRED" /><tx:method name="append*" propagation="REQUIRED" /><tx:method name="insert*" propagation="REQUIRED" /><tx:method name="save*" propagation="REQUIRED" /><tx:method name="update*" propagation="REQUIRED" /><tx:method name="modify*" propagation="REQUIRED" /><tx:method name="edit*" propagation="REQUIRED" /><tx:method name="delete*" propagation="REQUIRED" /><tx:method name="remove*" propagation="REQUIRED" /><tx:method name="repair" propagation="REQUIRED" /><tx:method name="delAndRepair" propagation="REQUIRED" /><tx:method name="get*" propagation="SUPPORTS" /><tx:method name="find*" propagation="SUPPORTS" /><tx:method name="load*" propagation="SUPPORTS" /><tx:method name="search*" propagation="SUPPORTS" /><tx:method name="datagrid*" propagation="SUPPORTS" /><tx:method name="*" propagation="SUPPORTS" /></tx:attributes></tx:advice><aop:config><aop:pointcut id="transactionPointcut" expression="execution(* wxd.service..*Impl.*(..))" /><aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" /></aop:config><!-- 配置druid监控spring jdbc --><bean id="druid-stat-interceptor" class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor"></bean><bean id="druid-stat-pointcut" class="org.springframework.aop.support.JdkRegexpMethodPointcut" scope="prototype"><property name="patterns"><list><value>wxd.service.*</value></list></property></bean><aop:config><aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut" /></aop:config></beans>

5 整合springMVC，新建配置文件spring-mvc.xml 主要作用：1启动注解 2 自动扫描@controller  3模型视图解析，配置如下

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->  <context:component-scan base-package="wxd.controller" /><!-- 避免IE执行AJAX时,返回JSON出现下载文件 --><bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"><property name="supportedMediaTypes"><list><value>text/html;charset=UTF-8</value></list></property></bean><!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 --><bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"><property name="messageConverters"><list><ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 --></list></property></bean><!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/" p:suffix=".jsp" /><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><property name="defaultEncoding"><value>UTF-8</value></property><property name="maxUploadSize"><value>32505856</value><!-- 上传文件大小限制为31M，31*1024*1024 --></property><property name="maxInMemorySize"><value>4096</value></property></bean></beans>

6 配置spring.xml 作用：扫描注入service

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsd"><!-- 引入属性文件 --><context:property-placeholder location="classpath:config.properties" /><!-- 自动扫描(自动注入) --><context:component-scan base-package="wxd.service" /></beans>

7 配置web.xml

<?xml version="1.0" encoding="UTF-8"?>  <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"><display-name>mybatis</display-name><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring.xml,classpath:spring-mybatis.xml</param-value></context-param><filter><description>字符集过滤器</description><filter-name>encodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><description>字符集编码</description><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><listener><description>spring监听器</description><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 防止spring内存溢出监听器 --><listener><listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class></listener><!-- spring mvc servlet --><servlet><description>spring mvc servlet</description><servlet-name>springMvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><description>spring mvc 配置文件</description><param-name>contextConfigLocation</param-name><param-value>classpath:spring-mvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springMvc</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping><welcome-file-list><welcome-file>/index.jsp</welcome-file></welcome-file-list><!-- 配置session超时时间，单位分钟 --><session-config><session-timeout>15</session-timeout></session-config></web-app>

8 log4j配置

为了方便调试，一般都会使用日志来输出信息，Log4j是Apache的一个开放源代码项目，通过使用Log4j，我们可以控制日志信息输送的目的地是控制台、文件、GUI组件，甚至是套接口服务器、NT的事件记录器、UNIX Syslog守护进程等；我们也可以控制每一条日志的输出格式；通过定义每一条日志信息的级别，我们能够更加细致地控制日志的生成过程。

配置详细说明

http://blog.csdn.net/zhshulin/article/details/37937365

通用配置如下：

</pre><pre name="code" class="html">#定义LOG输出级别  log4j.rootLogger=DEBUG,Console,File  #定义日志输出目的地为控制台  log4j.appender.Console=org.apache.log4j.ConsoleAppender  log4j.appender.Console.Target=System.out  #可以灵活地指定日志输出格式，下面一行是指定具体的格式  log4j.appender.Console.layout = org.apache.log4j.PatternLayout  log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n    #文件大小到达指定尺寸的时候产生一个新的文件  log4j.appender.File = org.apache.log4j.RollingFileAppender  #指定输出目录  log4j.appender.File.File = logs/ssm.log  #定义文件最大大小  log4j.appender.File.MaxFileSize = 10MB  # 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志  log4j.appender.File.Threshold = ALL  log4j.appender.File.layout = org.apache.log4j.PatternLayout  log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n  

9 mysql安装 代码生成

1 下载 mysql-5.5.20-winx64.msi，

2 下载Navicat_for_MySQL.exe 并配置链接，建测试表user

DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `id` int(20) NOT NULL AUTO_INCREMENT,
  `name` varchar(40) DEFAULT NULL,
  `passwd` varchar(9) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

3 按照http://blog.csdn.net/zhshulin/article/details/23912615操作用mybatis-generator-core-1.3.2自动创建代码

10 junit测试

建立完测试类后要执行maven test 编译java文件

问题：

maven instal时报错，找不到wxd/mapping/路径，把mapping文件夹拷贝入workspace该项目的target下的wxd目录下编译即可通过

参考http://blog.csdn.net/zhshulin/article/details/37956105

常见问题

1 测试时报*.xml不存在，或者一些类没有定义，在pom.xml中增加以下配置

<build>  <resources>   <resource>    <directory>src/main/java</directory>    <includes>     <include>**/*.xml</include>    </includes>   </resource>  </resources> </build>

原因：

maven默认会把src/main/resources下的所有配置文件以及src/main/java下的所有java文件打包或发布到target\classes下面，但是现实我们可能会在src/main/java下面也放置一些配置文件如hibernate配置文件或mybatis mapper配置文件等，如果不做一些额外配置，那我们打包后的项目可能找不到这些必须的资源文件，因此在pom.xml中增加类似如下配置，就会将src/main/java下的xml文件随同java编译后的class文件一同copy到相应的class目录

2 测试时报：java.lang.Exception: No tests found matching Method test2(test.TestMyBatis)  

原因是junit 加的@Test没有生效，原因不明，过一段时间就生效了，修改代码后也是等一会才能生效

3 maven install时报错 class path resource [spring.xml] cannot be opened because it does not exist
