# 简介 #

Logback是由log4j创始人设计的一个开源日志组件。3个组件：  
logback-core:提供了LogBack的核心功能，是另外两个组件的基础。  
logback-classic:实现了Slf4j的API，所以当想配合Slf4j使用时，需要引入logback-classic。  
logback-access:为了集成Servlet环境而准备的，可提供HTTP-access的日志接口。

# 配置 #

## 配置加载 ##

如果配置文件 logback-test.xml 和 logback.xml 都不存在，那么 logback 默认地会调用BasicConfigurator ，创建一个最小化配置。最小化配置由一个关联到根 logger 的ConsoleAppender 组成。输出用模式为%d\{HH:mm:ss.SSS\} \[%thread\] %-5level %logger\{36\} - %msg%n 的 PatternLayoutEncoder 进行格式化。root logger 默认级别是 DEBUG。

## 常见的logger配置 ##

<logger name="org.hibernate.type.descriptor.sql.BasicBinder" level="TRACE" />
    <logger name="org.hibernate.type.descriptor.sql.BasicExtractor" level="DEBUG" />
    <logger name="org.hibernate.SQL" level="DEBUG" />
    <logger name="org.hibernate.engine.QueryParameters" level="DEBUG" />
    <logger name="org.hibernate.engine.query.HQLQueryPlan" level="DEBUG" />
    
    
    <logger name="com.apache.ibatis" level="TRACE"/>
    <logger name="java.sql.Connection" level="DEBUG"/>
    <logger name="java.sql.Statement" level="DEBUG"/>
    <logger name="java.sql.PreparedStatement" level="DEBUG"/>

# SpringBoot #

spring boot默认使用logback实现。  
默认会加载classpath:logback-spring.xml或者classpath:logback-spring.groovy。  
需要自定义：logging.config=classpath:logback-vander.xml

基本配置：

<?xml version="1.0" encoding="UTF-8"?>
    <configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml"/>
    <logger name="org.springframework.web" level="DEBUG"/>
    </configuration>
