自定义lockback拦截配置

方法一：需要配置拦截字符

1.在 <evaluator>子标签下，  message.contains("response :")，contains里面就是配置需要拦截的字符串。如果当行里面有xxxx,就拦截下来

<!-- Configure the monthly calculator log  -->
    <appender name="JSONOUT" class="ch.qos.logback.core.rolling.RollingFileAppender">   
        <filter class="ch.qos.logback.core.filter.EvaluatorFilter">         
            <evaluator>  
              <expression>return message.contains("response :");</expression>   
            </evaluator>   
            <OnMatch>NEUTRAL</OnMatch>  
            <OnMismatch>DENY</OnMismatch>  
        </filter>  
        <file>H:/Java/workspace_one/OCR_Server/logs/ocr_server_json_result.log</file>

                <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                        <!-- Daily rollover -->
                        <fileNamePattern>H:/Java/workspace_one/OCR_Server/logs/ocr_server_json_result.log.%d{yyyy-MM-dd}.log
                        </fileNamePattern> 
        
                <!-- Keep 180 days' worth of history -->
                        <maxHistory>180</maxHistory>
         </rollingPolicy>
         
        <encoder>   
          <pattern>   
          %d{HH:mm:ss.SSS} %-5level [%thread] %logger - %msg%n  
          </pattern>   
        </encoder>   
    </appender>

 2.最后还不要忘记添加

<appender-ref ref="JSONOUT" />

3.不输出一些框架信息

把不想输出的包路径写进去

<logger name="org.springframework" level="info" />

 不输出info级别，只输出debug级别的：

<!-- Root Logger -->
        <root>
                <priority value="debug" />
                <appender-ref ref="console" />
                <appender-ref ref="file" />
        </root>

4.依赖包：

compile 'org.slf4j:slf4j-api:1.7.12'
  compile 'org.slf4j:jcl-over-slf4j:1.7.12'
  compile 'ch.qos.logback:logback-classic:1.1.3'
  
  compile 'org.codehaus.janino:janino:3.0.0'
  compile 'org.codehaus.janino:commons-compiler:3.0.0'

方法二：分文件

1.

<appender name="REGULAR_EXP" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>{path}/regular_exp_result.log</file>

        <encoder>
          <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level-%msg%n</pattern>
        </encoder>

        <filter class="ch.qos.logback.classic.filter.LevelFilter">
          <level>ERROR</level>
        </filter>

      <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
          <!-- Daily rollover -->
          <fileNamePattern>{path}/regular_exp_result.%d{yyyy-MM-dd}.log
          </fileNamePattern>

          <!-- Keep 180 days' worth of history -->
          <maxHistory>180</maxHistory>
      </rollingPolicy>

      <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
        <maxFileSize>50KB</maxFileSize>
      </triggeringPolicy>
    </appender>

 2.

<logger name="REGULAR_EXP" level="DEBUG">
          <appender-ref ref="REGULAR_EXP" />
      </logger>

 3.new logger 使用

private static final Logger regExLogger = LoggerFactory.getLogger("REGULAR_EXP");
