SpringBoot------自定义Logback日志

帮助文档：

https://docs.spring.io/spring-boot/docs/2.1.0.BUILD-SNAPSHOT/reference/htmlsingle/#boot-feature-logging

log4j.properties转换logback.xml

https://logback.qos.ch/translator/
https://logback.qos.ch/manual/index.html

转换前代码：

### 设置###
log4j.rootLogger = debug,stdout,D,E

### 输出信息到控制抬 ###
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n

### 输出DEBUG 级别以上的日志到=E://logs/error.log ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = E://logs/log.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = DEBUG
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n

### 输出ERROR 级别以上的日志到=E://logs/error.log ###
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File =E://logs/error.log
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n

1.添加pom.xml的依赖

<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">

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

2.添加lockback-spring.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>

<configuration>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>
                %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
            </pattern>
        </encoder>
    </appender>

    <!-- 日志记录器，日期滚动记录 -->
    <appender name="fileInfoApp" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <!-- 正在记录的日志文件的路径及文件名 -->
        <!-- <file>${LOG_PATH}/warn/log_warn.log</file> -->
        <!-- 日志记录器的滚动策略，按日期，按大小记录 -->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!-- 归档的日志文件的路径，例如今天是2013-12-21日志，当前写的日志文件路径为file节点指定，可以将此文件与file指定文件路径设置为不同路径，从而将当前日志文件或归档日志文件置不同的目录。
            而2013-12-21的日志文件在由fileNamePattern指定。%d{yyyy-MM-dd}指定日期格式，%i指定索引 -->
            <fileNamePattern>app_log/log/log-error-%d{yyyy-MM-dd}.%i.log</fileNamePattern>
            <!-- 表示只保留最近30天的日志，以防止日志填满整个磁盘空间。-->
            <maxHistory>30</maxHistory>
            <!--用来指定日志文件的上限大小，例如设置为1GB的话，那么到了这个值，就会删除旧的日志。-->
            <totalSizeCap>1GB</totalSizeCap>
            <!-- 除按日志记录之外，还配置了日志文件不能超过2M，若超过2M，日志文件会以索引0开始，命名日志文件，例如log-error-2013-12-21.0.log -->
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>2MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
       </rollingPolicy>
       <!-- 追加方式记录日志 -->
       <append>true</append>
       <!-- 日志文件的格式 -->
       <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
           <pattern>===%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level %logger Line:%-3L - %msg%n</pattern>
           <charset>utf-8</charset>
       </encoder>
       <!-- 此日志文件只记录war级别的 -->
       <filter class="ch.qos.logback.classic.filter.LevelFilter">
              <!-- 只保留error日志 -->
              <!-- level:debug,info,warn,error -->
           <level>ERROR</level>
           <onMatch>ACCEPT</onMatch>
           <onMismatch>DENY</onMismatch>
       </filter>
    </appender>

    <!-- root节点要放到appender之后 -->
    <root level="INFO">
        <appender-ref ref="STDOUT" />
        <appender-ref ref="fileInfoApp" />
    </root>
</configuration>

3.添加控制器

package top.ytheng.demo.controller;

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

@RestController
@RequestMapping("/api/v1/log")
public class LogController {

    private Logger logger = LoggerFactory.getLogger(this.getClass());

    @GetMapping("/test")
    public Object test() {

        logger.debug("this is debug level");
        logger.info("this is info level");
        logger.warn("this is warn level");
        logger.error("this is error level");
        return "success";
    }
}

4.添加启动类

package top.ytheng.demo;

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication //等于下面3个
//@SpringBootConfiguration
//@EnableAutoConfiguration
//@ComponentScan
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

5.右键项目Rum As启动，访问地址

http://localhost:8080/api/v1/log/test

如图：
