Springboot使用AOP实现统一处理Web请求日志

1.要使我们自定义的记录日志能够打印出来，我们需要先排除springboot默认的记录日志，添加如下的设置

2.新建 resources/log4j.properties

我的设置为：

# LOG4J\u914D\u7F6E

log4j.rootCategory=INFO, stdout, file, errorfile

log4j.category.com.wutongshu=DEBUG, bootfile

log4j.logger.error=errorfile

# \u63A7\u5236\u53F0\u8F93\u51FA

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %5p %c{}:%L - %m%n

# root\u65E5\u5FD7\u8F93\u51FA

log4j.appender.file=org.apache.log4j.DailyRollingFileAppender

log4j.appender.file.file=logs/all.log

log4j.appender.file.DatePattern='.'yyyy-MM-dd

log4j.appender.file.layout=org.apache.log4j.PatternLayout

log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %5p %c{}:%L - %m%n

# error\u65E5\u5FD7\u8F93\u51FA

log4j.appender.errorfile=org.apache.log4j.DailyRollingFileAppender

log4j.appender.errorfile.file=logs/error.log

log4j.appender.errorfile.DatePattern='.'yyyy-MM-dd

log4j.appender.errorfile.Threshold = ERROR

log4j.appender.errorfile.layout=org.apache.log4j.PatternLayout

log4j.appender.errorfile.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %5p %c{}:%L - %m%n

# com.springboot\u4E0B\u7684\u65E5\u5FD7\u8F93\u51FA

log4j.appender.bootfile=org.apache.log4j.DailyRollingFileAppender

log4j.appender.bootfile.file=logs/my.log

log4j.appender.bootfile.DatePattern='.'yyyy-MM-dd

log4j.appender.bootfile.layout=org.apache.log4j.PatternLayout

log4j.appender.bootfile.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %5p %c{}:%L ---- %m%n

3.然后创建Web层日志切面类，这里我设置的是controller层的所有请求都会打印日志信息

其中@Order(i)表示AOP切面的优先级

在切入点前的操作，按order的值由小到大执行
在切入点后的操作，按order的值由大到小执行

/**

 * 日志切面类

 */

@Aspect

@Component

@Order()

public class WebLogAspect {

    private Logger logger=Logger.getLogger(getClass());

    private ThreadLocal<Long> startTime=new ThreadLocal<>();

    @Pointcut("execution(public * com.*.*.web.*.*(..))")

    public void webLog(){

    }

    @Before(value = "webLog()")

    public void doBefore(JoinPoint point){

        startTime.set(System.currentTimeMillis());

        logger.info("WebLogAspect.doBefore............");

        ServletRequestAttributes attributes=

                (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();

        HttpServletRequest request=attributes.getRequest();

        logger.info("IP : "+request.getRemoteAddr());

        logger.info("URL:" + request.getRequestURL().toString());

        logger.info("HTTP_METHOD:" +request.getMethod());

        logger.info("CLASS_NAME : " + point.getSignature().getDeclaringTypeName()+"."+point.getSignature().getName());

        logger.info("ARGS : " + Arrays.toString(point.getArgs()));

    }

    @AfterReturning(value = "webLog()",returning = "ret")

    public void doAferReturning(Object ret){

        logger.info("WebLogAspect.doAfterReturning.............");

        logger.info("Resp: " + ret);

        logger.info("Spend Time : " + (System.currentTimeMillis()-startTime.get()));

    }

}
