ConfigBrowser插件
http://struts.apache.org/release/2.2.x/docs/config-browser-plugin.html
l 第一个开发实践
通过Struts2返回第一个JSON对象的源码下载：
http://bobproject.googlecode.com/svn/tags/tag_ReportWebApp_source_v1.0
一、通过maven的pom.xml引入相关组件
1、struts2的dependency
http://mvnrepository.com/artifact/org.apache.struts/struts2-core/2.3.15.2
2、json的dependency
<dependency>
<groupId>net.sf.json-lib</groupId>
<artifactId>json-lib</artifactId>
<version>2.4</version>
<classifier>jdk15</classifier>
</dependency>
3、javax.servlet的dependency
<dependency>
<groupId>org.eclipse.jetty.orbit</groupId>
<artifactId>javax.servlet</artifactId>
<version>3.0.0.v201112011016</version>
</dependency>
4、log4j2的dependency http://logging.apache.org/log4j/2.x/maven-artifacts.html
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.0-beta9</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.0-beta9</version>
</dependency>
5、ConfigBrowser插件
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-config-browser-plugin</artifactId>
<version>2.3.15.2</version>
</dependency>
二、搭建struts2程序框架
1、创建ReportAction.java
创建public void doAction() throws IOException；
2、创建struts.xml配置文件
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<package name="default" extends="struts-default" namespace="/">
<action name="testJSONFromActionByGeneral" class="com.tuoming.iqa.action.ReportAction"
method="doAction">
</action>
</package>
</struts>
3、web.xml中添加struts2配置代码
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
</web-app>
4、index.jsp中添加客户端代码
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<metahttp-equiv="Content-Type"content="text/html; charset=UTF-8">
<title>Struts2与JSON测试</title>
<script type="text/javascript" src="js/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="js/index.js"></script>
</head>
<body>
<a href="<%=basePath%>testJSONFromActionByGeneral.action" title="测试从Action以常规方式获取JSON数据">测试从Action以常规方式获取JSON数据</a>
</body>
</html>
5、pom.xml中添加tomcat-maven-plugin的plugin
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>tomcat-maven-plugin</artifactId>
<version>1.0-beta-1</version>
<configuration>
<url>http://localhost:8080/manager/text</url>
<path>/ ReportWebApp</path>
<server>tomcat</server>
<username>admin</username>
<password>password</password>
</configuration>
</plugin>
6、Right Click >> Run As >> Maven Build,在窗口中的Goals内输入：package tomcat:redeploy
三、采用Log4j2实现日志功能
1、指定目录下创建log4j2.xml，内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appenders>
<RollingFile name="outErrorFile" fileName="RWA_logs/exception.log"
filePattern="RWA_logs/$${date:yyyy-MM}/exception-%d{MM-dd-yyyy}-%i.log.gz">
<PatternLayout
pattern="%d{yyyy.MM.dd HH:mm:ss z} %-5level %class{36} %L %M - %msg%xEx%n" />
<SizeBasedTriggeringPolicy size="10MB" />
</RollingFile>
<RollingFile name="outDebugFile" fileName="RWA_logs/debug.log"
filePattern="RWA_logs/$${date:yyyy-MM}/exception-%d{MM-dd-yyyy}-%i.log.gz">
<PatternLayout
pattern="%d{yyyy.MM.dd HH:mm:ss z} %-5level %class{36} %L %M - %msg%xEx%n" />
<SizeBasedTriggeringPolicy size="10MB" />
</RollingFile>
<RollingFile name="outInfoFile" fileName="RWA_logs/info.log"
filePattern="RWA_logs/$${date:yyyy-MM}/exception-%d{MM-dd-yyyy}-%i.log.gz">
<PatternLayout
pattern="%d{yyyy.MM.dd HH:mm:ss z} %-5level %class{36} %L %M - %msg%xEx%n" />
<SizeBasedTriggeringPolicy size="10MB" />
</RollingFile>
<Console name="consolePrint" target="SYSTEM_OUT">
<PatternLayout
pattern="%d{yyyy.MM.dd HH:mm:ss z} %-5level %class{36} %L %M - %msg%xEx%n" />
</Console>
</appenders>
<loggers>
<root level="DEBUG">
<appender-ref level="DEBUG" ref="outDebugFile" />
<appender-ref level="ERROR" ref="outErrorFile" />
<appender-ref level="INFO" ref="outInfoFile" />
</root>
</loggers>
</configuration>
2、需打印日志的Class中添加成员变量代码
private static Logger log = LogManager.getLogger(ReportInfo.class.getName());
3、打印日志方法如下
log.debug("通过action是以传统方式返回JSON数据");
4、C: omcatinRWA_logs目录下查看日志是否生成
