关于idea maven工程创建struts2入门配置及案例

1.在maven工程下添加需要导入的jar包节点

<dependencies>

  <dependency>

    <groupId>org.apache.struts</groupId>

    <artifactId>struts2-core</artifactId>

    <version>2.3.24</version>

  </dependency>

  <dependency>

    <groupId>org.apache.struts.xwork</groupId>

    <artifactId>xwork-core</artifactId>

    <version>2.3.24</version>

  </dependency>

</dependencies>

2.web-inf文件下配置web.xml节点

  <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>

3.构建index.jsp页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<%@ taglib prefix="s" uri="/struts-tags" %>

<%@ page isELIgnored="false" %>

<html>

<head>

    <title>Title</title>

</head>

<body>

<s:fielderror value="error"></s:fielderror>

<s:actionerror/>

<s:property value="ret"/>

<s:debug/>

<form action="testAction" method="post">

    用户名：<input name="uname"/><br/>

    密码：<input name="upwd"/><br/>

    <input type="submit"/>

</form>

</body>

</html>

4.创建TestAction

方法一：实现Action接口

public String execute() throws Exception {

        System.out.println("action");

        if (this.getUname().equals("")) {

            addFieldError("error", "用户名为空值");

            addActionError("actionerror");

            return "ret1";

        }else if (this.getUpwd().equals("")){

            addFieldError("error", "密码为空值");

            return "ret1";

        }

        return "ret1";

    }

方法二：继承ActionSupport类

public void validate() {

        System.out.println("actionsuppo");

        if (this.getUname().equals("")) {

            addFieldError("error", "用户名为空值");

            addActionError("actionerror");

        }else if (this.getUpwd().equals("")){

            addFieldError("error", "密码为空值");

        }

    }

5.配置struts.xml文件

<constant name="struts.enable.DynamicMethodInvocation" value="false"/>

    <constant name="struts.devMode" value="true"/>

    <package name="default" namespace="/" extends="struts-default">

        <action name="testAction" class="action.TestAction">

            <result name="input">index.jsp</result>

        </action>

    </package>

6.测试页面

但用户名为空时

但密码为空时
