,# play 介绍
Play作为web容器，相当于struts+ibatis+页面，都涉及到。启动的方式也是有几种，可以采用tomcat方式进行启动，也可以用play项目自带的test.launch来启动(默认端口号是9000,这个主要是基于mina来实现通信的). 优点： 1) 编译java文件。刷新浏览器无需重启服务 2) 基于hibernate，Memcached等插件 3) 非阻塞io模型,允许基于长轮询和websockedts的web应用- 先看下如何建立一个play 项目
1) 下载jar包 http://downloads.typesafe.com/play/1.2.7/play-1.2.7.zip
官方网站是:http://www.playframework.com
2) 配置环境变量 Path = D:\paly-1.2.7
3) cmd- >play 查看是否安装成功
4) play new Test cases : 创建Test cases项目
play eclipsify Test cases
将Test cases 导入到eclipse 中，右键运行Test cases.launch。在浏览器输入http://localhost:9000
// test.launch文件 <?xml version="1.0" encoding="UTF-8"?><launchConfiguration type="org.eclipse.jdt.launching.localJavaApplication"> <listAttribute key="org.eclipse.debug.core.MAPPED_RESOURCE_PATHS"> <listEntry value="/test"/> </listAttribute> <listAttribute key="org.eclipse.debug.core.MAPPED_RESOURCE_TYPES"> <listEntry value="4"/> </listAttribute> <booleanAttribute key="org.eclipse.debug.core.appendEnvironmentVariables" value="true"/> <listAttribute key="org.eclipse.jdt.launching.CLASSPATH"> <listEntry value="<?xml version="1.0" encoding="UTF-8"?> <runtimeClasspathEntry containerPath="org.eclipse.jdt.launching.JRE_CONTAINER" javaProject="test" path="1" type="4"/> "/> <listEntry value="<?xml version="1.0" encoding="UTF-8"?> <runtimeClasspathEntry internalArchive="/test/conf" path="3" type="2"/> "/> <listEntry value="<?xml version="1.0" encoding="UTF-8" standalone="no"?> <runtimeClasspathEntry externalArchive="E:\play-1.2.7/modules/testrunner/lib/play-testrunner.jar" path="3" type="2"/> "/> <listEntry value="<?xml version="1.0" encoding="UTF-8"?> <runtimeClasspathEntry id="org.eclipse.jdt.launching.classpathentry.defaultClasspath"> <memento exportedEntriesOnly="false" project="test"/> </runtimeClasspathEntry> "/> </listAttribute> <booleanAttribute key="org.eclipse.jdt.launching.DEFAULT_CLASSPATH" value="false"/> <stringAttribute key="org.eclipse.jdt.launching.MAIN_TYPE" value="play.server.Server"/> <stringAttribute key="org.eclipse.jdt.launching.PROJECT_ATTR" value="test"/> <stringAttribute key="org.eclipse.jdt.launching.VM_ARGUMENTS" value="-Xmx512m -Xms512m -XX:PermSize=256m -XX:MaxPermSize=512m -Xdebug -Dplay.debug=yes -Dplay.id= -Dapplication.path="${project_loc:test}" -Djava.endorsed.dirs="E:\play-1.2.7/framework/endorsed" -javaagent:"E:\play-1.2.7/framework/play-1.2.7.jar""/></launchConfiguration>- 来利用maven 来查看play 源代码
1) 下载maven包并且解压 http://apache.fayea.com/maven/maven-3/3.1.1/binaries/apache-maven-3.1.1-bin.zip
2) 环境变量
maven_home=C:\Program Files\Java\apache-maven-3.1.1
path变量末尾增加：%maven_home%\bin
检查是否安装成功：在CMD中输入mvn，看是否识别该命令
3）I) 用play命令来创建
进入到已经创建好的play目录下eg: cd C:\Test cases
play install maven
对于已经存在的工程，在conf/application.conf中加入以下内容 module.maven=${play.path}/modules/maven-head
play mvn:init 命令在工程目录下自动生成pom.xml文件，然后将需要依赖的dependency 加入pom.xml文件即可（需要添加对应的repositories）
play mvn:update 或者 play mvn:up 会获取定义的依赖，并将其放在app/lib下面
play mvn:re 刷新依赖包
play mvn:src 这里的操作是获取源码包的jar包。source包从maven中央仓库同步到maven本地仓库。
II) maven命令来实现
新建个项目
play new Test cases
play eclipsify Test cases
然后导入eclipse中，右键configuer->转变成maven项目
修改pom.xml。

</build></project>把依赖的jar包都删掉，除了pay-1.12.jar
cmd 项目所在的位置
mvn dependency:sources 下载源代码
2. 部署项目到tomcat下
cmd C:\Test cases
play war –exclude .svn:logs:tmp:db -o E:\war2131 生成war包
将这个包放入到E:\清理\tomcat\t1\webapps\ROOT ,tomcat下。重启tomcat即可
附加一个添加java的源码，也就是rt.jar
- 打开eclipse，点 “window”-> “Preferences” -> “Java” -> “Installed JRES”
- 此时”Installed JRES”右边是列表窗格，列出了系统中的 JRE 环境，选择你的JRE，然后点边上的 “Edit…”， 会出现一个窗口(Edit JRE)
- 选中rt.jar文件的这一项：“c:\program files\java\jre_1.5.0_06\lib\rt.jar” 点 左边的“+” 号展开它
- 展开后，可以看到“Source Attachment:(none)”，点这一项，点右边的按钮“Source Attachment…”, 选择你的JDK目录下的 “src.zip”文件
maven 仓库地址： http://repo.maven.apache.org/maven2/
根据jar来搜索所在maven仓库的地址http://mvnrepository.com/artifact/org.sonatype.tycho/org.eclipse.jdt.core/3.6.0.v_A48
所有的jar和源代码都是从maven仓库中下载的
