Struts2_接收参数
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 }

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 }

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 }
