@Target(ElementType.METHOD)

public class ProductSendLogAspect {
@Resource
private RedisDaoImpl redisDao;
@Pointcut("@annotation(com.xkd.common.annotation.ProductSendLog)")
public void aspect() {

@AfterReturning(value="@annotation(annotation)", returning = "obj")
public void doAfter(JoinPoint joinPoint, ProductSendLog annotation, Object obj){
...
}
@Component
@Aspect
@Slf4j
public class StatisticalLogAspect {
@Resource
private RedisDaoImpl redisDao;
@Pointcut("@annotation(com.xkd.common.annotation.StatisticalLogAnnotation)")
public void aspect() {

@AfterReturning(value="@annotation(annotation)", returning = "obj")
public void doAfter(JoinPoint joinPoint, StatisticalLogAnnotation annotation, Object obj){
...
}
以上情况，同一个接口添加了两个自定义注解，并且两个自定义注解所执行的aop的自定义注解对象都是通过@annotation()方式引入的。 将会导致两个自定义注解一起注入到参数的自定义注解类中。
例如：StatisticalLogAspect类中的doAfter方法的参数StatisticalLogAnnotation 在依赖注入的时候，会注入StatisticalLogAnnotation对象和ProductSendLog对象。导致参数类型不匹配问题。
将其中一个切面地注入自定义注解类的方式修改成其他形式。
例如：
@Component
@Aspect
@Slf4j
public class ProductSendLogAspect {
@Resource
private RedisDaoImpl redisDao;
@Pointcut("@annotation(com.xkd.common.annotation.ProductSendLog)")
public void aspect() {
}
@AfterReturning(value = "aspect()", returning = "obj")
public void doAfter(JoinPoint joinPoint, Object obj){
MethodSignature signature = null;
if (joinPoint.getSignature() instanceof MethodSignature) {
signature = (MethodSignature) joinPoint.getSignature();
}
if (signature != null) {
Method method = signature.getMethod();
ProductSendLog annotation = method.getAnnotation(ProductSendLog.class);
}
...
}
