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%>"> <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-test
