概要：

logback的配置，需要配置输出源appender，打日志的loger（子节点）和root（根节点），实际上，它输出日志是从子节点开始，子节点如果有输出源直接输入，如果无，判断配置的addtivity，是否像上级传递，即是否向root传递，传递则采用root的输出源，否则不输出日志。

appender：

负责写日志的组件，它有两个必要属性name和class。name指定appender名称，class指定appender的全限定名，如ConsoleAppender 把日志输出到控制台，该组件常用子节点<encoder>等。

<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> 
      <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> 
        <fileNamePattern>logFile.%d{yyyy-MM-dd}.log</fileNamePattern> 
        <maxHistory>30</maxHistory> 
      </rollingPolicy> 
      <encoder> 
        <pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern> 
      </encoder> 
    </appender>

logger：

用来设置某一个包或具体的某一个类的日志打印级别、以及指定<appender>。<loger>仅有一个name属性，一个可选的level和一个可选的addtivity属性。

root：

它也是<loger>元素，但是它是根loger,是所有<loger>的上级。只有一个level属性，因为name已经被命名为"root",且已经是最上级了。

示例：

<configuration debug="false">
          
        <property name="LOG_HOME" value="/home" />  
           
        <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
            <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> 
                  
                <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>   
            </encoder> 
        </appender>
           
        <appender name="FILE"  class="ch.qos.logback.core.rolling.RollingFileAppender">   
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                
                <FileNamePattern>${LOG_HOME}/TestWeb.log.%d{yyyy-MM-dd}.log</FileNamePattern> 
                
                <MaxHistory>30</MaxHistory>
            </rollingPolicy>   
            <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> 
                 
                <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>   
            </encoder> 
            
           <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
             <MaxFileSize>10MB</MaxFileSize>
           </triggeringPolicy>
        </appender> 
        
        <logger name="org.hibernate.type.descriptor.sql.BasicBinder"  level="TRACE" />  
        <logger name="org.hibernate.type.descriptor.sql.BasicExtractor"  level="DEBUG" />

        <logger name="java.sql.Statement" level="DEBUG"/>
        <logger name="java.sql.PreparedStatement" level="DEBUG"/>
        
        
        <root level="INFO">
            <appender-ref ref="STDOUT" />
            <appender-ref ref="FILE" />
        </root> 
           
        <appender name="DB" class="ch.qos.logback.classic.db.DBAppender">
             
            <connectionSource class="ch.qos.logback.core.db.DriverManagerConnectionSource">
                
               <dataSource class="com.mchange.v2.c3p0.ComboPooledDataSource">
                  <driverClass>com.mysql.jdbc.Driver</driverClass>
                  <url>jdbc:mysql://127.0.0.1:3306/databaseName</url>
                  <user>root</user>
                  <password>root</password>
                </dataSource>
            </connectionSource>
      </appender>
    </configuration>

<logger> 继承自 <root> ， logger中的additivity默认为true，会将消息传递给父（<root>节点），<logger>不指定appender或，level，则只能依赖root的appender或level
