springBoot添加日志管理

一。

近期自己的项目想要一个记录日志的功能，而springboot本身就内置了日志功能，然而想要输入想要的日志，并且输出到磁盘，然后按天归档，或者日志的切分什么的，自带的日志仅仅具有简单的功能，百度了一番，总结如下，适合大多数的应用场景

二。

springboot的pom文件都会引一个parent

　　<parent>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starter-parentartifactId>
        <version>2.0.0.RELEASEversion>
    parent>

点进去这个parent，会有一个这个dependency

　　<parent>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-dependenciesartifactId>
        <version>2.0.0.RELEASEversion>
        <relativePath>../../spring-boot-dependenciesrelativePath>
    parent>

再点进去就是2.0版本，所谓的它给你集成的各种包依赖，而且规定了版本号，其中有一个包如下

　　 <dependency>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starterartifactId>
        <version>2.0.0.RELEASEversion>
    dependency>

再点进去

    <dependency>
      <groupId>org.springframework.bootgroupId>
      <artifactId>spring-boot-starter-loggingartifactId>
      <version>2.0.0.RELEASEversion>
      <scope>compilescope>
    dependency>

再点，啊哈，出来了，这些都是原有的日志包，所以，不必再引依赖了，直接用就ok了，用法如下：

    <dependency>
      <groupId>ch.qos.logbackgroupId>
      <artifactId>logback-classicartifactId>
      <version>1.2.3version>
      <scope>compilescope>
    dependency>
    <dependency>
      <groupId>org.apache.logging.log4jgroupId>
      <artifactId>log4j-to-slf4jartifactId>
      <version>2.10.0version>
      <scope>compilescope>
    dependency>
    <dependency>
      <groupId>org.slf4jgroupId>
      <artifactId>jul-to-slf4jartifactId>
      <version>1.7.25version>
      <scope>compilescope>
    dependency>

============================分割线====================================

首先，官方推荐使用的xml名字的格式为：logback-spring.xml而不是logback.xml，至于为什么，因为带spring后缀的可以使用这个标签。

在resource下创建logback-spring.xml文件

内容如下，每行都有注释了

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

其中说一下，彩色日志这个东东，得下载插件才可以哦，怎么下？我不知道哈哈

然后在yml或者properties中配置

logging.config=classpath:log/logback-spring.xml
logging.path=D:/nmyslog/nmys

日志的使用方式，就跟普通使用一样，只不过，此配置配置的是不仅在控制台输出而且在磁盘上也会保留，并且info/debug/error/warn的日志都区分开了，并且按照每天做了归档
