1.加载Struts 2类库

<dependencies>
  <!-- Struts 2 核心包-->
  <dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-core</artifactId>
    <version>2.3.4.1</version>
  </dependency>
  <!-- Struts 2 构建基础-->
  <dependency>
    <groupId>org.apache.struts.xwork</groupId>
    <artifactId>xwork-core</artifactId>
    <version>2.3.4.1</version>
  </dependency>
</dependencies>
<build>
  <resources>
    <resource>
      <directory>src/main/java</directory>
      <includes>
        <include>**/*.xml</include>
      </includes>
    </resource>
  </resources>
</build>

2.配置wbe.xml文件

<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.开发视图层页面

<%@ taglib uri="/struts-tags" prefix="s"   %>
<html>
<head>
    <title>Struts</title>
</head>
<body>
    <h2>第一个Strusts 2案例</h2>
    <s:property value="message"></s:property>
    <form action="helloWorld" method="post">
        用户名：<input name="uname" /><s:fielderror fieldName="uname"></s:fielderror>
        密码：  <input type="password" name="upwd"/><s:fielderror fieldName="pwd" ></s:fielderror>
        <input type="submit" value="提交">
    </form>
</body>
</html>
 

4.开发控制层页面Action

public class HelloWorldAction extends ActionSupport implements Action {
    private String uname;
    private String upwd;
    private String message;
    //唯一的执行方法
    public String execute() throws Exception {
        if (this.getUname().equals("1")&&this.getUpwd().equals("1")){
            this.setMessage("Hello!"+this.getUname());
            return "success";
        }else{
            return "input";
        }
        
    }
    //服务器端数据校验
    public void validate(){
        if (this.getUname().length()==0){
            addFieldError("uname","用户名不能为空");
        }
        if (this.getUpwd().length()==0){
            addFieldError("pwd","密码不能为空");
        }
    }

    public String getUpwd() {
        return upwd;
    }

    public void setUpwd(String upwd) {
        this.upwd = upwd;
    }

    public String getUname() {
        return uname;
    }

    public void setUname(String uname) {
        this.uname = uname;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }
    
}

5.配置Struts.xml

<struts>
    <package name="default" namespace="/" extends="struts-default">
        <action name="helloWorld" class="HelloWorldAction">
            <result name="success">/First.jsp</result>
            <result name="input">/First.jsp</result>
        </action>
    </package>
</struts>

6.部署、运行项目

　　

  • 直接运行

  • 正确输入用户名，密码
