1. logback 의존성 추가

https://mvnrepository.com/search?q=logback

testImplementation group: 'ch.qos.logback', name: 'logback-classic', version: '1.2.11'

 

2. application.yml 설정

# 파일 삭제
# /project-board/back-end/gundam/src/main/resources/application.properties

# 파일 추가
# /project-board/back-end/gundam/src/main/resources/application.yml


# server
server:
  port: 8080
  servlet:
    context-path: /
    # encoding:
    #   charset: UTF-8
    #   enabled: true
    #   force: true



# log level
logging:
  logback:
    rollingpolicy:
      file-name-pattern: "/Users/djkang/dev/gundam/product-src/logs/abc.%d{yyyy-MM-dd}.%i"
  pattern:
    file: "[%d{HH:mm:ss.SSS}][%-5level][%logger.%method:line%line] - %msg%n"
  file:
    name: /Users/djkang/dev/gundam/product-src/logs/abc.log
    max-history: 300
  level:
    '[com.main.gundam.sample]': INFO
    org:
      springframework: INFO

 

3. 로그 확인 코드 추가

package com.main.gundam.controller;

import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import lombok.RequiredArgsConstructor;
import lombok.extern.slf4j.Slf4j;

// import org.slf4j.Logger;
// import org.slf4j.LoggerFactory;

@RestController
@RequestMapping(value = "/main", produces = {MediaType.APPLICATION_JSON_VALUE, MediaType.TEXT_PLAIN_VALUE})
@RequiredArgsConstructor
@Slf4j
public class RestApiController {

    // private static final Logger logger = LoggerFactory.getLogger(RestApiController.class);

    @GetMapping("home")
    public String home() {
        log.info("home");
        // logger.info("home");

        return "<h1>home</h1>";
    }
    
    @GetMapping("/get/{userId}")
    public String get(@PathVariable(value = "userId") final String userId) {
        // logger.info("get user");
        log.info("get user");

        return userId;
    }
}

 

4. 설정된 경로에 로그파일 생기는지 확인
