模块开发完成后,接到通知需要添加操作记录功能,看着那一堆接口,如果一个方法一个方法的加,那真是太麻烦了。为了偷懒,就百度了一下,发现可以通过自定义注解和aop的形式来统一添加操作记录,只需要在每个方法上面添加自定义的注解就可以了。我在这里用的是springboot2.0以及jpa,废话不多说,直接上代码~
自定义注解serverLog
import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target; /** * 请输入一段话进行描述 * * @author Holley * @create 2018-07-03 14:23 **/ @Target(ElementType.METHOD) @Retention(RetentionPolicy.RUNTIME) public @interface serverLog { public String comment() default ""; }
