在Sping Boot logback的使用

在Sping Boot logback的使用：
只需要4步即可完成配置：
1 在application.properties中配置logback.xml

# log
logging.config=classpath:logback.xml
debug=true
#彩色输出日志
#NEVER：禁用ANSI-colored输出（默认项）
#DETECT：会检查终端是否支持ANSI，是的话就采用彩色输出（推荐项）
#ALWAYS：总是使用ANSI-colored格式输出，若终端不支持的时候，会有很多干扰信息，不推荐使用
spring.output.ansi.enabled=detect

2 配置logback，如下：

<!-- Logback configuration. See http://logback.qos.ch/manual/index.html -->
<configuration scan="true" scanPeriod="10 seconds">


    <include resource="org/springframework/boot/logging/logback/base.xml"/>
    <!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径-->
    <property name="LOG_PATH" value="app-log"/>

    <!-- 彩色日志依赖的渲染类 -->
    <conversionRule conversionWord="clr"
                    converterClass="org.springframework.boot.logging.logback.ColorConverter" />
    <conversionRule conversionWord="wex"
                    converterClass="org.springframework.boot.logging.logback.WhitespaceThrowableProxyConverter" />
    <conversionRule conversionWord="wEx"
                    converterClass="org.springframework.boot.logging.logback.ExtendedWhitespaceThrowableProxyConverter" />

    <!-- 彩色日志格式 -->
    <property name="CONSOLE_LOG_PATTERN" value="${CONSOLE_LOG_PATTERN:-%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}" />
    <!-- Console 输出设置 -->

3 添加maven依赖：

<!-- https://mvnrepository.com/artifact/ch.qos.logback/logback-classic -->
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.2.3</version>
    <scope>test</scope>
