结果:

在这之前，要引入

<!-- AspectJ --><dependency><groupId>org.aspectj</groupId><artifactId>aspectjrt</artifactId><version>${org.aspectj-version}</version></dependency><!-- javassist  --><dependency><groupId>org.javassist</groupId><artifactId>javassist</artifactId><version>3.20.0-GA</version></dependency>
