  <display-name>框架测试</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>

  <!-- struts配置 -->
    <filter>
      <filter-name>struts2</filter-name>
      <filter-class>
        org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
      </filter-class>
   </filter>

   <filter-mapping>
      <filter-name>struts2</filter-name>
      <url-pattern>/*</url-pattern><!-- 对-ura用 -->
   </filtermpping>

</web-app>

5.action类

package test;

public class HelloStruts{
    public String execute() {
        System.out.println("执行action");
        return "success";
    }
}

6. 配置struts.xml

<?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="test" namespace="" extends="struts-default">
        <!-- 包名自定 -->
            <action name="hellostruts" class="test.HelloStruts" method="execute">
              <!-- name: action名称，在jsp页面用 action的name.action访问 -->
              <!-- class: 实现类 -->
              <!-- method: 实现的方法 -->
                <result name="success"><!-- 结果集 ，根据name的值转到不同的页面 -->
                /test.jsp
                </result>
            </action>
        </package>
    </struts>

7. 测试页面index.jsp和test.jsp

index.jsp:

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<!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>Insert title here</title>
</head>
<body>
<s:form action="/hellostruts.action"><!--/actionname . action--!>
    <s:submit value="Click Here"></s:submit>
</s:form>
</body>
</html>

这里写图片描述

test.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">
