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>
