springBoot记录日志log4j2

一，新建maven项目

二，pom文件中加入一下配置

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.liu</groupId>
<artifactId>springBootHelloword</artifactId>
<version>0.0.1-SNAPSHOT</version>


   <parent>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-parent</artifactId>
       <version>1.5.22.RELEASE</version>
   </parent>
   <dependencies>
       
       <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-web</artifactId>
           <exclusions>
<exclusion>

<！--排除项目依赖的logback日志-->
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
</exclusion>
</exclusions>
       </dependency>
       <dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-log4j2</artifactId>
</dependency>

</dependencies>
</project>

三,加入log配置文件log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration status="OFF">
<appenders>

<RollingFile name="RollingFileDebug" fileName="./logs/debug.log"
filePattern="logs/$${date:yyyy-MM}/debug-%d{yyyy-MM-dd}-%i.log.gz">
<Filters>
<ThresholdFilter level="DEBUG"/>
<ThresholdFilter level="INFO" onMatch="DENY" onMismatch="NEUTRAL"/>
</Filters>
<PatternLayout

<Policies>
<SizeBasedTriggeringPolicy size="500 MB"/>
<TimeBasedTriggeringPolicy/>
</Policies>
</RollingFile>

<RollingFile name="RollingFileInfo" fileName="./logs/info.log"
filePattern="logs/$${date:yyyy-MM}/info-%d{yyyy-MM-dd}-%i.log.gz">
<Filters>

<ThresholdFilter level="INFO"/>
<ThresholdFilter level="WARN" onMatch="DENY" onMismatch="NEUTRAL"/>
</Filters>
<PatternLayout
pattern="[%d{yyyy-MM-dd HH:mm:ss}] %-5level %class{36} %L %M - %msg%xEx%n"/>
<Policies>
<SizeBasedTriggeringPolicy size="500 MB"/>
<TimeBasedTriggeringPolicy/>
</Policies>
</RollingFile>

<RollingFile name="RollingFileWarn" fileName="./logs/warn.log"
filePattern="logs/$${date:yyyy-MM}/warn-%d{yyyy-MM-dd}-%i.log.gz">
<Filters>

<Policies>
<SizeBasedTriggeringPolicy size="500 MB"/>
<TimeBasedTriggeringPolicy/>
</Policies>
</RollingFile>

<RollingFile name="RollingFileError" fileName="./logs/error.log"
filePattern="logs/$${date:yyyy-MM}/error-%d{yyyy-MM-dd}-%i.log.gz">
<ThresholdFilter level="ERROR"/>
<PatternLayout
pattern="[%d{yyyy-MM-dd HH:mm:ss}] %-5level %class{36} %L %M - %msg%xEx%n"/>
<Policies>
<SizeBasedTriggeringPolicy size="500 MB"/>
<TimeBasedTriggeringPolicy/>
</Policies>
</RollingFile>

<RollingFile name="druidSqlRollingFile" fileName="./logs/druid-sql.log"
filePattern="logs/$${date:yyyy-MM}/api-%d{yyyy-MM-dd}-%i.log.gz">
<PatternLayout pattern="[%d{yyyy-MM-dd HH:mm:ss}] %-5level %L %M - %msg%xEx%n"/>
<Policies>
<SizeBasedTriggeringPolicy size="500 MB"/>
<TimeBasedTriggeringPolicy/>
</Policies>
</RollingFile>
</appenders>

<logger name="druid.sql.Statement" level="debug" additivity="false">
<appender-ref ref="druidSqlRollingFile"/>
</logger>
<logger name="druid.sql.Statement" level="debug" additivity="false">
<appender-ref ref="druidSqlRollingFile"/>
</logger>

<Logger name="org.apache.catalina.startup.DigesterFactory" level="error" />
<Logger name="org.apache.catalina.util.LifecycleBase" level="error" />
<Logger name="org.apache.coyote.http11.Http11NioProtocol" level="warn" />
<logger name="org.apache.sshd.common.util.SecurityUtils" level="warn"/>

<Logger name="org.eclipse.jetty.util.component.AbstractLifeCycle" level="error" />
<Logger name="org.hibernate.validator.internal.util.Version" level="warn" />
<logger name="org.springframework.boot.actuate.autoconfigure.CrshAutoConfiguration" level="warn"/>
<logger name="org.springframework.boot.actuate.endpoint.jmx" level="warn"/>
<logger name="org.thymeleaf" level="warn"/>
</loggers>
</configuration>

四，加入全局配置文件

application.yml

server:
port: 8888
# 日志配置文件
logging:
config: classpath:log4j2/log4j2.xml

五加入测试类

package com.liu.controller;

import java.util.HashMap;
import java.util.Map;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

//标识该接口全部返回json格式。
@RestController

public class HelloWorldController {

   Logger logger = LoggerFactory.getLogger(HelloWorldController.class);

   @RequestMapping("/index")
   public String index() {
       logger.debug("Hello debug");
       logger.info("Hello info");
       logger.warn("Hello warn");
       logger.error("Hello error");
       return "success";
   }

   @RequestMapping("/getMap")
   public Map<String, Object> getMap() {
       Map<String, Object> result = new HashMap<String, Object>();
       result.put("errorCode", "200");
       result.put("errorMsg", "成功..");
       return result;
   }

}

六，运行项目

http://localhost:8888/index

index

[17:16:36.622] INFO com.liu.controller.HelloWorldController 21 index - Hello info
[17:16:36.625] WARN com.liu.controller.HelloWorldController 22 index - Hello warn
[17:16:36.632] ERROR com.liu.controller.HelloWorldController 23 index - Hello error

项目路径下多了几个日志文件
