一.springboot默认日志配置

1.springboot默认日志配置是使用logback

2.引用springboot依赖包时会自动加载依赖jar包

3.项目中配置logback

===========引用springboot依赖的pom

======application.properties文件

###Tomcat Config
    server.port=8080
    server.tomcat.uri-encoding=UTF-8
    
    ####DataSource Config
    spring.datasource.platform=mysql
    spring.datasource.url=jdbc:mysql://127.0.0.1:3306/lpinfo?useSSL=false&useUnicode=true&characterEncoding=utf8
    spring.datasource.driverClassName=com.mysql.jdbc.Driver
    spring.datasource.username=root
    spring.datasource.password=123456
    
    ###SPBdefaultLoggin Config
    logging.level.root=info

package com.spf.demo;
    
    
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.test.context.junit4.SpringRunner;
    
    /**
     * Unit test for simple App.
     */
    
    
    @RunWith(SpringRunner.class)
    @SpringBootTest(classes = AppTest.class)
    public class AppTest {
        Logger logger = LoggerFactory.getLogger(getClass());
    
        // 日志输出等级 高>低   error > warn > info > debug >trace
        //SpringBoot默认是info级别，只会输出info及以上级别的日志
        @Test
        public void test() {
            logger.error("如果配置文件日志等级error--->[日志只能输出error等级日志]");
            logger.warn("如果配置文件日志等级warn--->[日志只能输出error,warn等级日志]");
            logger.info("如果配置文件日志等级info--->[日志只能输出error,warn,info等级日志]");
            logger.debug("如果配置文件日志等级debug--->[日志只能输出error,warn,info,debug等级日志]");
            logger.trace("如果配置文件日志等级trace--->[日志只能输出error,warn,info,debug,trace等级日志]");
        }
    
    }

运行结果:

二.springboot默认日志logback的详细配置

1.日志参数配置

application.properties中如果配置 logging.file 和logging.path

logging.file:   \# 日志文件,绝对路径或相对路径  
logging.path:   \# 保存日志文件目录路径  
logging.config: \# 日志配置文件,Spring Boot默认使用classpath路径下的日志配置文件,如:logback.xml  
logging.level.xxx:  \# 日志级别
