SpringBoot 自定义注解

1.定义一个注解

@Target({ElementType.METHOD,ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface TestOut {
    String value() default "";
}

2.编写切面文件

@Aspect
@Component
@SuppressWarnings({"unused"})
public class TestOutAspect {
    public static final Logger logger= LoggerFactory.getLogger(TestOutAspect.class);
    public static  final  String  Token="token";
    @Pointcut("@annotation(com.pa.xj.qa.matrix.biz.processor.service.nouse.TestOut)")
    public void annotationPointcut() {

    }
    @Before("annotationPointcut()")
    public void beforePointcut(JoinPoint joinPoint) {
        logger.info("我的注解 before");
        // 此处进入到方法前  可以实现一些业务逻辑
    }
    @Around("annotationPointcut()")
    public Object arount(ProceedingJoinPoint joinPoint) throws Throwable{
        logger.info("我的注解 around");
        return joinPoint.proceed();
    }
    @AfterReturning("annotationPointcut()")
    public void doAfterReturning(JoinPoint joinPoint) {
        logger.info("我的注解 after");
    }
}

3.使用注解

    @GetMapping(value = "/hs")
    @TestOut
    public GenericResponse<String> hstest() {
        GenericResponse<String> resp = new GenericResponse<>();
        resp.setStatus(ResponseConstants.STATUS_SUCCESS);
        resp.setMessage("OK");
        return resp;
    }
