Struts2--DomainModel接收参数---使用广泛!!!
1. JSP文件调用格式:
<a href="user/user!add?user.name=a&user.age=8">添加用户</a>
2. struts.xml文件:
<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>
3. action文件:和jsp传递过来的name和age一一对应传值进去
package com.bjsxt.struts2.user.action; import com.bjsxt.struts2.user.model.User; import com.opensymphony.xwork2.ActionSupport; 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; } }
Model:
package com.bjsxt.struts2.user.model; 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; } }
衍伸: DTO:通过DTO new一个User对象出来,把值传过去: newUser(UserDTO dto)()
package com.bjsxt.struts2.user.dto; public class UserDTO { private String name; private String password; private String confirmingPassword; }
