aop拦截的是controller层请求，正常的请求用@Before来拦截，
异常的请求用@AfterThrowing来拦截
1、引用aop jar包

    <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-aop</artifactId> <version>2.0.3.RELEASE</version> </dependency> 

2、代码实现

@Aspect
@Component
@Slf4j
public class LogAop { @Autowired private MongoTemplate mongoTemplate; @Pointcut("execution(public * com.caody.muyi.controller.*.*(..))") public void logAop(){}; @Before("logAop()") public void around(JoinPoint joinPoint){ log.info("user:cdy"); log.info("time:" new Date()); log.info("CLASS_METHOD : "   joinPoint.getSignature().getDeclaringTypeName()   "."   joinPoint.getSignature ().getName()); log.info("ARGS : "   Arrays.toString(joinPoint.getArgs())); OperationLog operationLog = new OperationLog(); operationLog.setLogname("cdy"); operationLog.setLogtype("业务日志"); operationLog.setCreatetime(new Date()); operationLog.setUserid(1); operationLog.setClassname(joinPoint.getSignature().getDeclaringTypeName()); operationLog.setMethod(joinPoint.getSignature().getName()); operationLog.setSucceed("成功"); operationLog.setMessage(""); mongoTemplate.save(operationLog); } // @AfterReturning(returning = "object", pointcut = "logAop()") // public void after(Object object){ // System.out.println(object); // log.info("RESPONSE : "   object); // } @AfterThrowing(pointcut = "logAop()", throwing="e") public void afterThrowing(JoinPoint joinPoint, Throwable e){ log.info("user:cdy"); log.info("time:" new Date()); log.info("path : "   joinPoint.getSignature().getDeclaringTypeName()   "."   joinPoint.getSignature ().getName()); log.info("param : "   Arrays.toString(joinPoint.getArgs())); log.info("异常代码:"   e.getClass().getName()); log.info("异常信息:"   e.getMessage()); OperationLog operationLog = new OperationLog(); operationLog.setLogname("cdy"); operationLog.setLogtype("异常日志"); operationLog.setCreatetime(new Date()); operationLog.setUserid(1); operationLog.setClassname(joinPoint.getSignature().getDeclaringTypeName()); operationLog.setMethod(joinPoint.getSignature().getName()); operationLog.setSucceed("失败"); operationLog.setMessage(e.getMessage()); mongoTemplate.save(operationLog); } }
