　　SpringBoot启动类，测试日志打印

package com.st;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class SpringbApplication {        private static final Logger logger = LoggerFactory.getLogger(SpringbApplication.class);    public static void main(String[] args) {        SpringApplication.run(SpringbApplication.class, args);        String msg = "习惯日志记录";        logger.info("打印日志...{}",msg);    }}

　　启动后，控制台输出如下：
