springboot配置日志存储路径和使用springboot+log4j打印日志输出

一.配置springboot默认的日志存储路径

这个是使用springboot自带的日志，然后配置其存储路径。

1.1 工程结构

1.2 pom文件

    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.11</version>
      <scope>test</scope>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

1.3 application配置文件

#################################################日志####################################################
#logging.config= classpath:logback-spring.xml  暂时没有启用，有需要再改成单独xml方式
#spring boot 自带日志 Jakarta Commons Logging API (JCL)
logging.file=../14.log
logging.level.com.ljf=DEBUG

1.4测试类

package com.ljf.spring.boot.demo;





import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * Hello world!
 *
 */
@SpringBootApplication
public class App 
{
    private static final Logger logger = LoggerFactory.getLogger(App.class);
   // private static Logger logger = Logger.getLogger(App.class);
    public static void main(String[] args) {

        final String[] temp = args;
        SpringApplication.run(App.class, args);
        logger.info("oops: main入口函数编码-" +System.getProperty("file.encoding"));
        try{
            int k=5/0;
        }
        catch (Exception e){
            e.printStackTrace();
            logger.error("算术异常====================="+e);
        }
        logger.info("启动完成了！！！！！！" );

    }

}

二.springboot+log4j日志存储

2.1 工程结构

2.2 pom文件

  <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.11</version>
      <scope>test</scope>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-test</artifactId>
      <scope>test</scope>
    </dependency>
