Spring+springmvc+maven adding facets using @aspectj

I do it by myself on the information on the Internet, for reference only.

Be clear: Using the @aspect annotation method, the project is a MAVEN project.

Using the @aspect annotation method, the main areas that need to be modified are:

1, pom file, add:

<!-- https://mvnrepository.com/artifact/org.aspectj/aspectjweaver  -->    <dependency>        < Groupid>org.aspectj</groupid>        <artifactid> aspectjweaver</artifactid>        <version>1.7.4</ version>    </dependency>    <!-- https:// mvnrepository.com/artifact/aspectj/aspectjrt -->    <dependency>         <groupId>org.aspectj</groupId>         <artifactId>aspectjrt</artifactId>         <version>1.7.4</version>    </dependency> 

Here's a question to be aware of. The version I used here was 1.5.4, but when I started it, I encountered an error,

0 can ' t find referenced pointcut, this problem makes me very puzzled, later after the online search information, said is the environmental problem.

In general:

My JDK version is 1.7, so I switched to 1.7.4ok.

2, SPRINGMVC configuration, I here is the default name, called Springmvc-servlet.xml

This configuration file needs to be added

<!--scan AOP, which corresponds to its own defined annotation class--<context:component-scan base-package= "Com.tarena.vote.aspect"/> <!--start a SPECTJ annotation support, Proxy-target-class equals true is mandatory with Cglib proxy--<aop:aspectj-autoproxy proxy-target-class= "true"/>

3, define the annotation class.

Description: I this is an experimental nature, so there is no specific business code. Inside you can add the business you need, such as logging, transaction control, and so on.

At this point, the work that needs to be done has been completed. The results of running the project are as follows:
