Action接收参数有三种方式
Action接收参数有三种方式，分别是字段属性方式、域模型方式（常用）、模型驱动方式。
字段属性方式：
public class UserAction extends ActionSupport {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
前台传参方式：？name=tom
域模型方式:
public class User {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
public class UserAction extends ActionSupport {
private User user;
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
前台传参方式：？user.name=tom
模型驱动方式:
public class User {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
public class UserAction extends ActionSupport implements ModelDriven<User>{
private User user = new User();
public String add() {
System.out.println("name=" + user.getName());
System.out.println("age=" + user.getAge());
return SUCCESS;
}
@Override
public User getModel() {
return user;
}
}
前台传参方式：？name=tom
