@RestController
@Slf4j
public class HelloController {

    @GetMapping("/hello")
    public String hello() {
        log.info("s");
        return "Welcome to springboot2 world ~";
    }

}

上述使用到slf4j的日志功能时，启动报错：

网上很多文章都说是lombok插件没有按照，但是我是安装过了的。所以问题不是出在lombok插件上。
后来我将lombok升级到最新版本就可以了，看了是lombok老版本对于新版的IDEA或者springboot支持不是很好。
