SPRINGAOP to monitor the execution time of each method in the service layer

Using AOP is too convenient and especially suitable for this type of scenario.

The code is as follows, where the information to be counted is written to the log file, or it can be designed to be written into a table.

Package Com.ecsoft.interceptor;import Org.aspectj.lang.ProceedingJoinPoint;import Org.aspectj.lang.annotation.Around;import Org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.reflect.MethodSignature;import Org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.stereotype.Component;@Aspect@Component Public classTimeinterceptor {Private StaticLogger log = Loggerfactory.GetLogger(Timeinterceptor.class);//Service layer Statistics time slices, type must be final string type, the variables to be used in annotations can only be static constant type     Public Static FinalString point ="Execution (* com.ecsoft.service). *impl.* (..))
