【Struts2复习知识点八】DomaimModel域模型接收参数

 DomaimModel域模型  就是将参数封装成 dto 对象。

struts.xml

<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>

User.java

public class User {
    private String name;
    private int age;
    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;
    }
}

 UserAction.java

public class UserAction extends ActionSupport {

    private User user;

    // private UserDTO userDTO;
    public String add() {
        System.out.println("name=" + user.getName());
        System.out.println("age=" + user.getAge());
        return SUCCESS;
    }

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }

}
