struts2框架配置

项目整体结构
web.xml
过滤器是必要的，其他的辅助配置暂时不管

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">  <display-name>HelloWord</display-name>  <!-- 过滤器 -->  <filter>    <filter-name>struts2</filter-name>    <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>  </filter>  <!-- 映射(映射名称与过滤器保持一致) --> <filter-mapping>    <filter-name>struts2</filter-name>    <url-pattern>/*</url-pattern> </filter-mapping> <!-- 起始页面 -->  <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list></web-app>

struts.xml
1. :将每个功能模块独立出来用include引用
2.
3. 拦截器
4. 全局配置类似于ssm中的jdbc.properties）

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC        "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"        "http://struts.apache.org/dtds/struts-2.5.dtd"><struts>   <package name="default" namespace="/" extends="struts-default">        <action name="as" class="com.wx.Action.HelloWorldAction">            <result>/result.jsp</result>        </action>        <action name="result">            <result>/result.jsp</result>        </action>   </package></struts>

HelloWorldAction.java

package com.wx.Action;import com.opensymphony.xwork2.ActionSupport;public class HelloWorldAction extends ActionSupport {    /**     *      */    private static final long serialVersionUID = -8615452363248473209L;    @Override    public String execute() throws Exception {        System.out.println("Action:第一个struts项目");        return SUCCESS;    }

result.jsp
