Struts2入门

使用Struts2开发程序的步骤

1.导入jar包

 <dependency>
            <groupId>javaee</groupId>
            <artifactId>javaee-api</artifactId>
            <version>5</version>
        </dependency>

        <dependency>
            <groupId>org.apache.struts</groupId>
            <artifactId>struts2-core</artifactId>
            <version>2.3.4.1</version>
        </dependency>

        <dependency>
            <groupId>org.apache.struts.xwork</groupId>
            <artifactId>xwork-core</artifactId>
            <version>2.3.4.1</version>
        </dependency>

 

 

2.配置  web.xml文件

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>

  <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>

</web-app>

 

 

3.页面

<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<s:form method="POST" action="userAction">
    请输入用户名： <s:textfield  name="username"></s:textfield> <br/>
    <s:textfield name="password"></s:textfield><br/>
    <s:submit value="登陆"></s:submit>
</s:form>
</body>
</html>

 

4.控制层

public class UserAction implements Action{
    //SpringMvc Controller
    public String execute() throws Exception {
        return SUCCESS;
    }
}

 

 

5.Struts2.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="default" namespace="/" extends="struts-default">
        <action name="userAction" class="cn.bdqn.action.UserAction">
            <result name="success">/index.jsp</result>
            <result name="input">/login.jsp</result>
        </action>
    </package>
</struts>

 

6.部署，运行项目
