Springboot整合log4j2【详细步骤】

1.去除logback中的依赖包

 1 <dependency>
 2             <groupId>org.springframework.boot</groupId>
 3             <artifactId>spring-boot-starter</artifactId>
 4             <exclusions>
 5                 <exclusion>
 6                     <groupId>org.springframework.boot</groupId>
 7                     <artifactId>spring-boot-starter-logging</artifactId>
 8                 </exclusion>
 9             </exclusions>
10         </dependency>

2.添加log4j2的依赖

 1     <dependency>
 2             <groupId>org.apache.logging.log4j</groupId>
 3             <artifactId>log4j-api</artifactId>
 4             <version>2.10.0</version>
 5         </dependency>
 6         <dependency>
 7             <groupId>org.apache.logging.log4j</groupId>
 8             <artifactId>log4j-core</artifactId>
 9             <version>2.10.0</version>
10         </dependency>        

3.默认的properties配置对log4j2不够友好,我们应用外部配置文件,在资源文件夹src/main/resources下添加log4j2.xml或者log4j2-spring.xml,启动后spring boot自动加载,配置文件的内容如下:

<?xml version="1.0" encoding="utf-8"?>  
<configuration>  
    <properties>  
        <!-- 文件输出格式 -->  
        <property name="PATTERN">%d{yyyy-MM-dd HH:mm:ss.SSS} |-%-5level [%thread] %c [%L] -| %msg%n</property>  
    </properties>  
  
    <appenders>  
        <Console name="CONSOLE" target="system_out">  
            <PatternLayout pattern="${PATTERN}" />  
        </Console>  
    </appenders>  
      
    <loggers>  
        <logger name="com.roncoo.education" level="debug" />  
        <root level="info">  
            <appenderref ref="CONSOLE" />  
        </root>  
    </loggers>  
  
</configuration>  

配置完成重启工程,日志输出格式将使用该配置的格式输出
