SpringBoot使用自定义的日志框架，日志的存储方式为json日志格式

「爱情、让人受尽委屈。」 2022-05-21 09:34 330阅读 0赞

首先SpringBoot实现了它自己的日志框架即默认日志Logback，可以直接在SpringBoot配置文件配置 比如logging.path=xx，logging.level.root=xx等等，启动项目会自动生成对应的日志文件并记录，但是不能实现json格式的日志存储，所以为了满足需要，我们可以选择自定义的的日志并配置，

SpringBoot自1.4以上的版本开始，不支持log4日志转而开始使用log4j2日志，要使用自定义的日志框架的话，必须把SpringBoot默认使用的日志排除,提示log4j2支持json日志格式

log4j 2.x版本不再支持像1.x中的.properties后缀的文件配置方式，2.x版本配置文件后缀名只能为”.xml”,”.json”或者”.jsn”.

<dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-web</artifactId>
       <exclusions>
          <exclusion>
             <groupId>org.springframework.boot</groupId>
             <artifactId>spring-boot-starter-logging</artifactId>
          </exclusion>
       </exclusions>
    </dependency>

在引入log4j2 依赖

<dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-log4j2</artifactId>
       <version>1.5.8.RELEASE</version>
    </dependency>

<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> <log4j2.level>debug</log4j2.level> <log4j2.root.path>/data/springcloud/logs/xx/config/config</log4j2.root.path> <log4j2.error.path>/data/springcloud/logs/xx/config/config</log4j2.error.path>

<dependency>
          <groupId>com.fasterxml.jackson.core</groupId>

        </dependency>
        <dependency>
          <groupId>com.fasterxml.jackson.core</groupId>
          <artifactId>jackson-databind</artifactId>
    
        </dependency>

<sourceDirectory>src/main/java</sourceDirectory>
        <resources>
          <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
            <includes>
              <include>**/*</include>
            </includes>
          </resource>
        </resources>

添加必须的插件

<plugin>
              <artifactId>maven-resources-plugin</artifactId>
              <configuration>
                <encoding>utf-8</encoding>
                <useDefaultDelimiters>true</useDefaultDelimiters>
              </configuration>
            </plugin>
    
      <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
      </plugin>

SpringBoot配置文件指定log4j.xml

> logging.config=classpath:log4j2.xml

log4j2.xml的配置：  
log4j2有很多的布局方式，其中 JosnLayout 表示记录方式是json方式

<?xml version="1.0" encoding="UTF-8" ?>
    <configuration status="WARN">
    
        
        <Properties>
            <Property name="pattern">%d{yyyy-MM-dd HH:mm:ss,SSS} %5p %c{1}:%l - %m%n</Property>
        </Properties>
    
    
        <Loggers>
            <Root level="DEBUG">
                <AppenderRef ref="console"></AppenderRef>
                <AppenderRef ref="rolling_file"></AppenderRef>
            </Root>
            
           
        </Loggers>
    
        <Appenders>
            <Console name="console" target="SYSTEM_OUT" follow="true">
                
                <ThresholdFilter level="INFO" onMatch="ACCEPT" onMismatch="DENY"/>
    
    
                 
    
    
                
    
    
    
            </Console>
            
            <RollingFile name="rolling_file" fileName="${log4j2.root.path}.log" filePattern="${log4j2.root.path}_%d{yyyy-MM-dd}.log">
                <JsonLayout/>
                <ThresholdFilter level="error" onMatch="ACCEPT" onMismatch="DENY"/>
    
               
    
    
                <Policies>
                    <TimeBasedTriggeringPolicy/>
                    <SizeBasedTriggeringPolicy size="100 MB"/>
                </Policies>
    
    
            </RollingFile>
    
            <File name="file" fileName="${log4j2.package.path}.log">
                
                <ThresholdFilter level="DEBUG" onMatch="ACCEPT" onMismatch="DENY"/>
               
                <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
            </File>
    
        </Appenders>
    
    </configuration>

**如果报下面这个错，说明SpringBoot自带的日志包为排除干净**
