控制层:HelloAction.java
package spring_mvc;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
//@Controller注解解析的时候看作控制器
@Controller
public class HelloAction {
public HelloAction(){
System.out.println("---------------------"+this.hashCode());
}
//hello.action的请求都交给都交由次方法处理
@RequestMapping(value="/hello.action")
public String Hello() throws Exception{
System.out.println("后台输出");
return "success.jsp";
}
}
