java 分布式微服务配置统一的日志输出包括logstash-Toy模板网

在springcloud分布式微服务中，每个微服务都要配置一个日志输出文件，当微服务多起来的时候，日志输出有变动就要一个一个微服务去修改，这样使工作量增加，变得很麻烦，还有可能出现错误。

对日志文件进行统一的配置处理是个不错的选择。

首先在微服务中有一个基础的模块是存放一些基础的，共用的工具，配置，common模块，所有项目都依赖common模块。

微服务统一日志管理,java,分布式,微服务

首先在服务中appliction-dev.yml中进行配置：

微服务统一日志管理,java,分布式,微服务

logging:
  path: /yunpan/logs/admin
  config: classpath:logback-spring.xml
# logstash连接配置
  host: 
  port: 
  level:
    root: info

在服务中进行spring_logback.xml配置：

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

<configuration debug="false" packagingData="true">

    <!-- log application level -->
    <springProperty scope="context" name="LOG_LEVEL" source="logging.level.root" />

    <include resource="com/zj/common/logback/commonLogback.xml" />

    <!-- 日志输出级别 -->
    <root level="${LOG_LEVEL}">
        <appender-ref ref="CONSOLE" />
        <appender-ref ref="ALL_LOG" />
        <appender-ref ref="ALL_ERROR" />
        <appender-ref ref="LOGSTASH" />
    </root>

</configuration>

在commonLogback.xml 中这样配置，当然还可以添加其他的配置属性，具体配置可以另行查找。

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

    <include resource="org/springframework/boot/logging/logback/defaults.xml" />
    <!-- <configuration scan="false" scanPeriod="60 seconds" debug="false"> -->
    <!-- log application name -->
    <springProperty scope="context" name="springAppName" source="spring.application.name" />
    <springProperty scope="context" name="logLevel" source="logging.level.root" />
    <!--设置系统日志目录-->
    <springProperty scope="context" name="logPath" source="logging.path"/>
    <!--logstash输入地址-->
    <springProperty scope="context" name="LOG_HOST" source="logging.host"/>
    <springProperty scope="context" name="LOG_PORT" source="logging.port"/>

    <property name="FILE_LOG_PATTERN"

    <!--配置logstash-->

    <logger name="com.vanmilk" additivity="false" level="DEBUG">

        <appender-ref ref="ALL_ERROR" />
        <appender-ref ref="LOGSTASH" />

    <!-- 去掉spring打印，实际并没有错， Could not find default TaskScheduler bean异常 -->
    <logger name="org.springframework.scheduling">
        <level value="info" />
    </logger>

</included>

这样在以后添加其他的微服务只需要添加logback-spring.xml就可以了，其他的都会共用commonLogback.xml中的省去了许多工作量。

最好的是能在common模块中再加一个AOP进行全局日志输出管理。文章来源地址https://www.toymoban.com/news/detail-654065.html
