【Struts2复习知识点七】-用Action的属性接收参数

struts.xml

View Code

<struts>
<constant name="struts.devMode" value="true" />
<package name="user" extends="struts-default" namespace="/user">

<action name="user" class="com.bjsxt.struts2.user.action.UserAction">
<result>/user_add_success.jsp</result>
</action>
</package>
</struts>

 UserAction.java

View Code

package com.bjsxt.struts2.user.action;

import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport {

private String name;
private int age;

public String add() {
        System.out.println("name=" + name);
        System.out.println("age=" + age);
return SUCCESS;
    }

public String getName() {
return name;
    }

public void setName(String name) {
this.name = name;
    }

public int getAge() {
return age;
    }

public void setAge(int age) {
this.age = age;
    }

}

name和age会自动注入到 UserAction.java 中。 此注入是通过set方法注入的，换言之setName对应参数name  ，注意拼写及大小写。
