springboot使用logback

由于springboot默认集成logback，所以不用引入任何pom新坐标

package com.greentran.origin.controller;


import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.*;


@Validated
@RestController
@RequestMapping("/user")
public class userController {

    private Logger logger = LoggerFactory.getLogger(this.getClass());

    @PostMapping(value = "login")
    public String login() {
        logger.info("nihaoshijie");
        return "登录返回值111";
    }


}
