  1.1
        直接创建接收的数据类型

 1         public class HelloAction extends ActionSupport {
 2     
 3             private String name;
 4             private int age;
 5             
 6             public String add(){
 7                 System.out.println("name="+name);
 8                 System.out.println("age="+age);
 9                 return SUCCESS;
10             }
11 
12             public String getName() {
13                 return name;
14             }
15 
16             public void setName(String name) {        //服务器自动调用
17                 this.name = name;
18             }
19 
20             public int getAge() {
21                 return age;
22             }
23 
24             public void setAge(int age) {
25                 this.age = age;
26             }
27         }

 


        在URL中: http://localhost:8080/Struts2_0100_Introduction/HelloAction_add?name=a&age=123
    1.2
        创建一个User类, 放置接收的参数

 1             public class User {
 2                 private String name;
 3                 private int age;
 4                 public String getName() {
 5                     return name;
 6                 }
 7                 public void setName(String name) {
 8                     this.name = name;
 9                 }
10                 public int getAge() {
11                     return age;
12                 }
13                 public void setAge(int age) {
14                     this.age = age;
15                 }
16             }

 


            不需要自己new user类

 1             public class UserAction extends ActionSupport{
 2                 private User user;
 3                 
 4                 public String add(){
 5                     System.out.println("User is run.");
 6                     System.out.println("name="+ user.getName());
 7                     System.out.println("age="+user.getAge());
 8                     return SUCCESS;
 9                 }
10                 public User getUser() {
11                     return user;
12                 }
13                 public void setUser(User user) {
14                     System.out.println("setUser run");
15                     this.user = user;
16                 }
17             }

 


            在URL中: http://localhost:8080/Struts2_0100_Introduction/UserAction_add?user.name=a&user.age=123
    1.3
        基本不用
        创建一个User类, 放置接收的参数
            public class User {
            添加了implements ModelDriven<User>
            需要自己new User
          

 1  public class ModelUserAction extends ActionSupport implements ModelDriven<User>{
 2                 private User user = new User();
 3                 
 4                 public String add(){
 5                     System.out.println("ModelUser is run.");
 6                     System.out.println("name="+ user.getName());
 7                     System.out.println("age="+user.getAge());
 8                     return SUCCESS;
 9                 }
10 
11                 @Override
12                 public User getModel() {
13                     // TODO 自动生成的方法存根
14                     return user;
15                 }
16             }
