springMvc+MyBatis+Maven配置和log4j相似的Logback

  实际上本文是配置与log4j相似的Logback!

pom.xml加载日志相关包:

<!-- log begin -->
<dependency>
<groupId>com.googlecode.log4jdbc</groupId>
<artifactId>log4jdbc</artifactId>
<version>1.2</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>${slf4j.version}</version>
<scope>runtime</scope>
</dependency>
<!-- 代码直接调用log4j会被桥接到slf4j -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>log4j-over-slf4j</artifactId>
<version>${slf4j.version}</version>
<scope>runtime</scope>
</dependency>
<!-- 代码直接调用common-logging会被桥接到slf4j -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jcl-over-slf4j</artifactId>
<version>${slf4j.version}</version>
<scope>runtime</scope>
</dependency>
<!-- 代码直接调用java.util.logging会被桥接到slf4j -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jul-to-slf4j</artifactId>
<version>${slf4j.version}</version>
<scope>runtime</scope>
</dependency>
<!-- log end -->

web.xml配置加载log4j:

<!-- login4j begin -->
<!-- 设置log4j存放Log文件位置（通过spring统一进行管理） -->
<context-param>
<param-name>webAppRootKey</param-name>
<param-value>log.root</param-value>
</context-param>

<!-- 加载log4j的配置文件 -->
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>classpath:/logback.xml</param-value>
</context-param>

<!--Spring默认刷新Log4j配置文件的间隔,单位为millisecond-->
<context-param>
<param-name>log4jRefreshInterval</param-name>
<param-value>60000</param-value>
</context-param>

<!--Spring用于log4j初始化的监听器-->
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
<!-- login4j end -->

根据需求logback.xml相关log4j配置:

<?xml version="1.0" encoding="UTF-8"?>
<configuration info="true">
<!-- 应用名称 -->
<property name="APP_NAME" value="wanxue" />
<!--日志文件的保存路径,首先查找系统属性-Dlog.dir,如果存在就使用其；否则，在当前目录下创建名为logs目录做日志存放的目录 -->
<property name="LOG_HOME" value="D:\\wanxueLog4j" />
<!-- 日志输出格式 -->
<property name="ENCODER_PATTERN"
value="%d{yyyy-MM-dd  HH:mm:ss.SSS} [%thread] %-5level 类名:%logger{80} 方法名:%M 行号:%L- %msg%n" />
<contextName>${APP_NAME}</contextName>

<!-- 控制台日志：输出全部日志到控制台 -->
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<Pattern>${ENCODER_PATTERN}</Pattern>
</encoder>
</appender>

<!-- 文件日志：输出全部日志到文件 -->
<appender name="FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>${LOG_HOME}/output.%d{yyyy-MM-dd}.log</fileNamePattern>
<!-- 保存30天日志文件   -->
<maxHistory>30</maxHistory>
</rollingPolicy>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<pattern>${ENCODER_PATTERN}</pattern>
</encoder>
</appender>

<!-- 错误日志：用于将错误日志输出到独立文件 -->
<appender name="ERROR_FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>${LOG_HOME}/error.%d{yyyy-MM-dd}.log</fileNamePattern>
<maxHistory>30</maxHistory>
</rollingPolicy>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<pattern>${ENCODER_PATTERN}</pattern>
</encoder>
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>WARN</level>
</filter>
</appender>

<!-- 独立输出的同步日志 -->
<appender name="SYNC_FILE"  class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>${LOG_HOME}/sync.%d{yyyy-MM-dd}.log</fileNamePattern>
<maxHistory>30</maxHistory>
</rollingPolicy>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<pattern>${ENCODER_PATTERN}</pattern>
</encoder>
</appender>

<logger name="log.sync" level="INFO" addtivity="true">
<appender-ref ref="SYNC_FILE" />
</logger>

<!-- 全局输出的方式 -->
<root level="INFO">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILE" />
<appender-ref ref="ERROR_FILE" />
</root>
</configuration>
