Logback日志配置

一直用log4j记日志多无聊。换个Logback来管理日志看看。

一、在pom文件中添加依赖的jar包：

......

<!-- 版本配置 -->
<properties>
	<slf4j.version>1.7.21</slf4j.version>
        <logback.version>1.1.7</logback.version>
</properties>

......

<!-- slf4j+LOGBack依赖包 -->
<dependency>
	<groupId>org.slf4j</groupId>
	<artifactId>slf4j-api</artifactId>
	<version>${slf4j.version}</version>
</dependency>
<dependency>
	<groupId>org.slf4j</groupId>
	<artifactId>log4j-over-slf4j</artifactId>
	<version>${slf4j.version}</version>
</dependency>
<dependency>
	<groupId>ch.qos.logback</groupId>
	<artifactId>logback-core</artifactId>
	<version>${logback.version}</version>
</dependency>
<dependency>
	<groupId>ch.qos.logback</groupId>
	<artifactId>logback-classic</artifactId>
	<version>${logback.version}</version>
</dependency>

二、添加 logback.xml文件到编译目录。具体内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
	<property name="LOG_HOME" value="c:/log" />
	
	<!-- 控制台输出 -->
	<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
		<Encoding>UTF-8</Encoding>
		<layout class="ch.qos.logback.classic.PatternLayout">
			<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n
			</pattern>
		</layout>
	</appender>
	
	<!-- 按照每天生成日志文件 -->
	<appender name="FILE"
		class="ch.qos.logback.core.rolling.RollingFileAppender">
		<Encoding>UTF-8</Encoding>
		<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
			<FileNamePattern>${LOG_HOME}/myApp.log.%d{yyyy-MM-dd}.log</FileNamePattern>
			<MaxHistory>30</MaxHistory>
		</rollingPolicy>
		<layout class="ch.qos.logback.classic.PatternLayout">
			<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n
			</pattern>
		</layout>
	</appender>

	<root level="DEBUG">
		<appender-ref ref="STDOUT" />
		<appender-ref ref="FILE" />
	</root>
</configuration>
