一、新建一个web项目,命名为:struts2
二、导入strut2所需的jar包 所需jar下载:http://pan.baidu.com/s/1dDxP4Z3
三、配置struts2的启动文件,在web.xml添加如下内容
<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>/*</url-pattern> </filter-mapping>
四、在src包下,新建struts.xml和struts.properties这2个文件
在struts.xml添加如下内容
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <!-- 请求参数的编码方式 --> <constant name="struts.i18n.encoding" value="UTF-8"/> <!-- 当struts.xml改动后,是否重新加载。默认值为false(生产环境下使用),开发阶段最好打开 --> <constant name="struts.configuration.xml.reload" value="true"/> <!-- 是否使用struts的开发模式。开发模式会有更多的调试信息。默认值为false(生产环境下使用),开发阶段最好打开 --> <constant name="struts.devMode" value="true"/> <!-- 设置浏览器是否缓存静态内容。默认值为true(生产环境下使用),开发阶段最好关闭 --> <constant name="struts.serve.static.browserCache" value="false" /> <!-- 含有Action类的路 从action包开始--> <constant name="struts.convention.package.locators" value="action" /> <package name="json" extends="json-default"> </package> </struts>
在struts.properties文件添加如下内容(指定结果页面的路径)
struts.convention.result.path=/
五、现在我们已经完成了strut2的环境配置了,接下来说介绍个使用的demo
demo1
在src下新建一个包命名为:com,在com包下新建一个包命名为:action,在action包下新建一个包命名为:demo
在demo 包下新建一个IndexAction.java的类
package com.action.demo;
import org.apache.struts2.convention.annotation.ParentPackage;
import com.opensymphony.xwork2.ActionSupport;
@ParentPackage(value = "struts-default")
public class IndexAction extends ActionSupport {
/**
*
*/
private static final long serialVersionUID = -903752277625921821L;
private String name;
@Override
public String execute() {
setName("stuts2 零配置的实现");
return SUCCESS;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
在WebRoot目录下新建一个文件夹命名为:demo
在WebRoot/demo目录新建一个index.jsp 内容如下
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<s:property value="name"/>
</body>
</html>
启动tomcat,在浏览器输入:http://localhost:8080/struts2/demo/index
demo2
在src/com/action/demo包下新建一个类IndexTestAction.java
package com.action.demo;
import org.apache.struts2.convention.annotation.Action;
import com.opensymphony.xwork2.ActionSupport;
@Action
public class IndexTestAction extends ActionSupport {
/**
*
*/
private static final long serialVersionUID = -903752277625921821L;
private String name;
@Override
public String execute() {
setName("stuts2 零配置的实现,路径配置," +
"IndexTestAction对应的结果界面:WebRoot/demo/index-text.jsp action去掉," +
"中间有大写的转换成小写,加上'-' " +
"例如:TestDemoAction 结果页面的是:test-demo.jsp");
return SUCCESS;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
在WebRoot/demo目录新建一个index-test.jsp 内容如下
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

<meta http-equiv="pragma" content="no-cache">
