利用AOP,logback区分服务日志文件

1.写好AOP类

@Aspect
@Component
public class LogAspect {
    final Logger logger = LoggerFactory.getLogger("aopLog"); //自定义的logger

    @Pointcut("execution(* com.gks.creditloan.dataservice.mapper.*.*.*(..))")
    public void mapperLog(){

    }

    /**
     * 前置通知(Before) 在目标方法被调用之前调用通知功能
     * @param joinPoint
     */
  //  @Before("mapperLog()")
    public void beforeAdvice(JoinPoint joinPoint){
        logger.info("beforeAdvice>>>>>> start");
        String name =joinPoint.getSignature().getName();
        logger.info("调用方法为:"+name);
        logger.info("beforeAdvice>>>>>> end");
    }
    /**
     * 后置通知(After)在目标方法完成之后调用通知，不会关心方法的输出是什么。
     * @param joinPoint
     */
  //  @After("mapperLog()")
    public void afterAdvice(JoinPoint joinPoint){
        logger.info("afterAdvice>>>>>> start");
        String name =joinPoint.getSignature().getName();
        logger.info("调用方法为:"+name);
        logger.info("afterAdvice>>>>>> end");
    }

    /**
     * 返回通知(After-returning)： 在目标方法成功执行之后调用通知。
     * @param joinPoint
     * @param result
     */
    @AfterReturning(pointcut = "mapperLog()",returning = "result")
    public Object afterReturnAdvice(JoinPoint joinPoint,Object result){
        logger.info("LogAspect.afterReturnAdvice>>>>>> start");
        //获取方法名
        String methodName = joinPoint.getSignature().getName();
        //获取类名
        String targetName = joinPoint.getSignature().getDeclaringType().getName();
        String name=targetName+"."+methodName;
        //获取传入目标方法的参数对象
        Object[] args= joinPoint.getArgs();
        //WriteDateUseDateFormat 默认为yyyy-MM-dd HH:mm:ss
        String argsJson= JSONObject.toJSONString(args, SerializerFeature.WriteDateUseDateFormat);
        logger.info("LogAspect调用方法"+name+"入参为:"+argsJson);
        logger.info("LogAspect调用方法"+name+"结果为:"+JSONObject.toJSONString(result, SerializerFeature.WriteDateUseDateFormat));
        logger.info("LogAspect.afterReturnAdvice>>>>>> end");
        return result;
    }

    /**
     * 异常通知(After-throwing)：在目标方法抛出异常后调用通知。
     */
    @AfterThrowing(pointcut = "mapperLog()",throwing = "exception")
    public void AfterThrowingAdvice(JoinPoint joinPoint,Exception exception){
        logger.info("LogAspect.AfterThrowingAdvice>>>>>> start");
        //获取方法名
        String methodName = joinPoint.getSignature().getName();
        //获取类名
        String targetName = joinPoint.getSignature().getDeclaringType().getName();
        String name=targetName+"."+methodName;
        //获取传入目标方法的参数对象
        Object[] args= joinPoint.getArgs();
        String argsJson= JSONObject.toJSONString(args, SerializerFeature.WriteDateUseDateFormat);
        logger.error("LogAspect.调用方法"+name+"参数为:"+argsJson);
        logger.error("LogAspect.调用方法"+name+"发生异常:",exception);
        logger.info("LogAspect.AfterThrowingAdvice>>>>>> end");
    }
}

2.定义自己的filter

public class LogFilter extends ThresholdFilter {
    String filterStr;

    @Override
    public FilterReply decide(ILoggingEvent event) {
        if (!isStarted()) {
            return FilterReply.NEUTRAL;
        }
        String msg= event.getMessage();
        if(msg !=null && !"".equals(msg)){
              if(msg.startsWith(filterStr)){
                  return FilterReply.DENY;
              }
        }
        return FilterReply.NEUTRAL;
    }

    public void setFilterStr(String filterStr) {
        this.filterStr = filterStr;
    }

    public String getFilterStr() {
        return filterStr;
    }
}

3.配置logback文件(我的是xml)

<!--增加SQL查询的入参出参的打印...见意只保留一个月时效,-->
<appender name="FILE-SQL" class="ch.qos.logback.core.rolling.RollingFileAppender">
   <filter class="com.lakala.creditloan.component.helper.LogFilter"  >
      <param name="filterStr" value="LogAspect" />
   </filter>
   <File>${log.base}/${log.name}-sql.log</File>
   <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"><!-- rollover daily -->
      <FileNamePattern>${log.base}/${log.name}-err-%d{yyyy-MM-dd}.%i.zip</FileNamePattern>
      <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
         <maxFileSize>30MB</maxFileSize><!-- or whenever the file size reaches 5MB -->
      </timeBasedFileNamingAndTriggeringPolicy>
      <!-- <maxHistory></maxHistory> -->
   </rollingPolicy>
   <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
      <Pattern>%-5level [%contextName] %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %logger.%method - %msg%n</Pattern>
   </encoder>
</appender>

<!--自定义的logger 在AOP中引用-->

<logger name="aopLog" additivity="false"><appender-ref ref="FILE-SQL" /> </logger>
