SpringBoot中slf4j的使用

1、引入jar包依赖

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>4.1.6.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>1.7.25</version>
        </dependency>

2、使用log4j

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

public Map<String,Object> test(HttpServletRequest request){

        logger.info("id:{}",id);
        logger.info("username:{}",username);

    }
