  • Struts2(一)

    一、Struts下载地址

    http://struts.apache.org/download.cgi

    二、导入包、配置Web.xml和struts.xml

    在下载的包中从示例中找到一些包就可以 

    struts2-2.3.4.1-allstruts-2.3.4.1appsstruts2-blankWEB-INFlib

    在Web.xml在加入

     <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>
      

    struts.xml可以在struts2-2.3.4.1-allstruts-2.3.4.1appsstruts2-blankWEB-INFclasses下找到示例更改即可

    <?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
        "http://struts.apache.org/dtds/struts-2.3.dtd">
    
    <struts>
    <!-- 
        <constant name="struts.enable.DynamicMethodInvocation" value="false" />
        <constant name="struts.devMode" value="false" />
    
        <package name="default" namespace="/" extends="struts-default">
    
            <default-action-ref name="index" />
    
            <global-results>
                <result name="error">/error.jsp</result>
            </global-results>
    
            <global-exception-mappings>
                <exception-mapping exception="java.lang.Exception" result="error"/>
            </global-exception-mappings>
    
            <action name="index">
                <result type="redirectAction">
                    <param name="actionName">HelloWorld</param>
                    <param name="namespace">/example</param>
                </result>
            </action>
        </package>
    
        <include file="example.xml"/>
        class="com.opensymphony.xwork2.ActionSupport"
     -->
        <!-- Add packages here -->
        <constant name="struts.devMode" value="true" />
    <package name="default" namespace="/" extends="struts-default">
     
           
            <action name="hello" class="com.pb.web.action.HelloAction3">
                <result>
                   /helloStruts.jsp
                </result>
            </action>
        </package>
    </struts>

    三、实现

    action

    package com.pb.web.action;
    
    import com.opensymphony.xwork2.ActionSupport;
    /*
     * 第三种 继承  ActionSupport类它是Action的实现类
     */
    public class HelloAction3 extends ActionSupport {
    
        /**
         * 
         */
        private static final long serialVersionUID = 1L;
    
        @Override
        public String execute() throws Exception {
            // TODO Auto-generated method stub
            return "success";
        }
        
    
    }

    页面

    helloStruts.jsp
    <%@ page language="java" contentType="text/html; charset=UTF-8"
        pageEncoding="UTF-8"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>HelloStruts</title>
    </head>
    <body>
    <h1 align="center">Hello Struts!</h1>
    </body>
    </html>

    在地址栏中输入http://localhost:8080/StrutsDemo1/hello.action

    以hello.action访问就可以跳到helloStruts.jsp页面
