Struts 2 框架搭建HelloWorld

1.导包

导入相应的jar包,在blank项目中会出现

2.书写Action类

package com.littlepage.struts;

public class HelloAction {
    public String hello() {
        System.out.println("HelloWorld");
        return "success";
    }
}

3.书写src/struts.xml

<?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>
    <package name="hello" namespace="/popopo" extends="struts-default">
        <action name="HelloAction" class="com.littlepage.struts.HelloAction" method="hello">
            <result name="success">/hello.jsp</result>
        </action>
    </package>
</struts>

4.将struts2核心Filter配置到web.xml

<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>

5.访问localhost:8080/项目名/namespace/actionname
