[Spring] 간단 한 Spring MVC 입문 예

머리말
테스트 특성 은 간단 한 Spring MVC 의 예 를 만들어 기록 해 야 한다. 예 일 뿐 입문 자의 예 일 뿐이다.
버 전 설명
POM 파일 을 설명 하고 도입 할 JAR 을 지정 합 니 다.

<properties>
        <spring.version>4.0.9.RELEASE</spring.version>
    </properties>

Controller 예 를 들 어 자주 사용 하 는 두 가지 방식 을 포함 합 니 다. 뛰 기, 되 돌려 주기 문자열 (예 를 들 어 JSON)

package controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import service.UserService;

@Controller
@RequestMapping("user")
public class UserController {
    
    @Autowired
    private UserService userService;
    
    @RequestMapping("update")
    public String update() {
        this.userService.update();
        return "hello"; //   hello.jsp  
    }
    
    @RequestMapping("isUser")
    @ResponseBody
    public String isUser() {
        this.userService.update();
        return "yes"; //      
    }

}

간단 한 서비스

package service;

import org.springframework.stereotype.Service;

@Service
public class UserService {
    
    public void update() {
        System.out.println("update user.");
    }
    
}
