Calculating service execution time using AOP implementations in Springboot

1, increase the pom.xml of the dependency rack package

<!--Introducing Spring AOP Dependency--
<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-aop</artifactId>
</dependency>

2. Writing AOP Tangent body classes
such as: Logservicetaketime

Description:
1. Add annotations on the body of the class to define the facets and declare @Aspect defined facets
2, @Pointcut ("Execution (* com.leecx.service).  *.*(..))") Defining pointcuts, generally using expressions to declare the scope of a cut
all methods, such as the Com.leecx.service package, will be intercepted to
3. @Before: The method of pre-processing before starting point
4. @After: The method of execution at the end of Pointcuts
5. @AfterReturning: The method executed after the Pointcut return data (typically used to wrap the returned data)
6. @Around: Methods to be executed before and after Pointcuts
  7. @AfterThrowing: Throws Exception Execution method
