問題描述
在切面中使用@DeclareParents註解的代碼如下：
@Aspect
public class MyAspect {
/**
* 爲UserService接口引入UserValidator接口
*/
@DeclareParents(value = "cn.zyt.springbootlearning.service.impl.UserServiceImpl+", defaultImpl = UserValidatorImpl.class)
public UserValidator userValidator;
}
啓動Spring Boot項目後，出現如下的異常信息：
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

問題解決
通過查找資料，發現上述的異常時由於如下註解中使用的+號導致的：
@DeclareParents(value = "cn.zyt.springbootlearning.service.impl.UserServiceImpl+", defaultImpl = UserValidatorImpl.class)
具體的解決方法就是將+號去掉，測試發現Spring Boot項目正常啓動，並且該註解的功能正常。這裏說明一下這裏使用的Spring Boot版本爲：2.2.4。
對於這裏+號的使用，資料中顯示：
之前版本（具體版本未知）中+號表示自身及其子類，但目前+僅表示其子類而不包括自身。
而由於當前UserServiceImpl對象沒有子類，因此這裏不應該帶+號。
