struts2开发action 的三种方法以及通配符、路径匹配原则、常量

struts2开发action 的三种方法

1、继承ActionSupport

public class UserAction extends ActionSupport {// Action中业务处理方法public String login() {System.out.println("UserAction.login()");
//      return "success";return SUCCESS;}
}

 

 

2、实现Action

public class UserAction3 implements Action {// Action中业务处理方法public String login() {System.out.println("UserAction.login()");return "success";}@Overridepublic String execute() throws Exception {return null;}
}

 

 

3、既不继承也不实现任何的方法

public class UserAction {private String userName;public void setUserName(String userName) {this.userName = userName;}// Action中业务处理方法public String login() {System.out.println("UserAction.login()" + userName);return "login";}public String register() {System.out.println("register()" + userName);return "register";}
}
