RequestMapping注解

HelloController類:

package cn.itcast.controller;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

// 控制器類

@Controller

@RequestMapping(path="/user")

public class HelloController {

/**

* 入門案例

* @return

*/

@RequestMapping(path="/hello")

public String sayHello(){

System.out.println("Hello StringMVC");

return "success";

}

/**

* RequestMapping注解

* @return

*/

@RequestMapping(value="/testRequestMapping
