AOP实现的统一日志处理
编写一个切面类
package com.**.sale.score.service.aspect; import com.zhangmen.sale.score.common.Result; import org.aspectj.lang.ProceedingJoinPoint; import org.aspectj.lang.annotation.Around; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Pointcut; import org.aspectj.lang.reflect.MethodSignature; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.dao.DuplicateKeyException; import org.springframework.stereotype.Component; @Aspect @Component public class ExceptionAspect { private static final Logger logger = LoggerFactory.getLogger(ExceptionAspect.class); @Pointcut("execution(* com.*.sale.score.service.impl.*Impl.*(..))") public void pointcut() { } @Around("pointcut()") public Object interceptor(ProceedingJoinPoint proceedingJoinPoint) { MethodSignature methodSignature = (MethodSignature) proceedingJoinPoint.getSignature(); String className = methodSignature.getDeclaringTypeName(); String methodName = methodSignature.getName(); Object returnObject; try { returnObject = proceedingJoinPoint.proceed(); } catch (Exception e) { if (e instanceof DuplicateKeyException) { logger.error("call {},系统异常-DuplicateKeyException异常:{}", methodName, e); throw (DuplicateKeyException) e; } if (e instanceof ArithmeticException) { logger.error("call {},系统异常-ArithmeticException异常:{}", methodName, e); throw (ArithmeticException) e; } if (e instanceof BusinessException) { logger.error("call {},自定义异常-BusinessException异常:{}", methodName, e); return Result.failure(e.getMessage()); } logger.error("call {},系统异常-其他异常:{}", methodName, e); throw new RuntimeException(e); } catch (Throwable e) { logger.error("call {},系统异常:{}", methodName, e); throw new RuntimeException(e); } return returnObject; } }
可以捕获自己定义的异常
package com.**.sale.score.service.aspect;/** /** *@ClassName BusinessException *@Description 自定义异常,全局捕获 *@Author wangwei *@Date 2019/10/16 10:27 *@Version V1.0 **/ public class BusinessException extends RuntimeException { public BusinessException(String message) { super(message); } }
