logback简介

为什么使用logback：

开始使用：

1.导入依赖：

2.在项目的resources目录下新建一个logback.xml文件

3.填入配置

4.项目启动

--------------------

### logback简介 ###

Logback是由[log4j][]创始人设计的又一个开源日志组件。logback当前分成三个模块：logback-core,logback- classic和logback-access。logback-core是其它两个模块的基础模块。logback-classic是log4j的一个 改良版本。此外logback-classic完整实现SLF4J API使你可以很方便地更换成其它日志系统如log4j或JDK14 Logging。logback-access访问模块与[Servlet][]容器集成提供通过Http来访问日志的功能。

### 为什么使用logback： ###

[企业开发中选择logback而不是log4j的理由 - Rollen Holt - 博客园 (cnblogs.com)][logback_log4j_ - Rollen Holt - _ _cnblogs.com]

### 开始使用： ###

#### 1.导入依赖： ####

其实在实际开发中我们不需要直接添加该依赖，你会发现spring-boot-starter其中包含了spring-boot-starter-logging，该依赖内容就是 Spring Boot 默认的日志框架就是logback。

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

#### 2.在项目的resources目录下新建一个logback.xml文件 ####

#### 4.项目启动 ####

项目启动后会自动生成一个logs文件夹包含Debug、Info、Warn、Error四个级别的log文件，可以点击所对应的级别日志文件查看。

Debug:指出细粒度信息事件对调试应用程序是非常有帮助的  
Info:消息在粗粒度级别上突出强调应用程序的运行过程  
Warn:输出警告及warn以下级别的日志  
Error:输出错误信息日志
