org.springframework.beans.factory.BeanCreationException 与事务管理器
org.springframework.beans.factory.BeanCreationException with Transaction Manager
我一直在 Spring 应用程序上研究 Spring MVC，但我正在努力让它工作。
我的应用程序具有以下结构：
- @Entity Classes
- @Repository Classes（使用 @Transactional 进行查询）
- @RestfulController Classes（为了简化，我没有实现服务层）
我想使用 @Transactional 进行查询，但在 on server start 配置它时收到错误消息spring xml 文件.

提前感谢您关注我的问题！
您在 CalendarController 中的 repository 字段应该由接口定义，而不是 class。 Spring 围绕您的 CalendarRepository 创建了一个 Proxy，它实现了相同的接口，但不是 CalendarRepository.
的子 class
这个问题是关于完全相同的问题：@Autowired return exception on UserDetails in Spring-security
You are trying to autowire your user details service by class, but that can't work, because the spring bean is actually a proxy created around that class (and not an instance of the class). The proxy will however implement all interfaces of the original bean, so injecting by interface is safe.
Exchange this line:
@Autowired
private MyCustomUserDetailsService myCustomUserDetailsService;
for this one:
@Autowired
private UserDetailsService myCustomUserDetailsService;
Read the section on Proxying Mechanisms in the Spring AOP to understand the details.
所以在你的情况下，你可以用你需要的方法创建一个新的 interface CalendarRepository，然后在 class CalendarRepositoryImpl implements CalendarRepository:
中实现
interface CalendarRepository extends br.com.milo.repository.Repository<Calendar, Owner>{
void save(Calendar calendar);
void update(Calendar calendar);
void delete(Integer id);
... (and all other methods you need)
}
@Repository
class CalendarRepositoryImpl implements CalendarRepository {
... (what you currently have in CalendarRepository)
}
class CalendarController {
@Autowired
CalendarRepository repository; // NOT CalendarRepositoryImpl
}

提前感谢您关注我的问题！
您在 CalendarController 中的 repository 字段应该由接口定义，而不是 class。 Spring 围绕您的 CalendarRepository 创建了一个 Proxy，它实现了相同的接口，但不是 CalendarRepository.
这个问题是关于完全相同的问题：@Autowired return exception on UserDetails in Spring-security
You are trying to autowire your user details service by class, but that can't work, because the spring bean is actually a proxy created around that class (and not an instance of the class). The proxy will however implement all interfaces of the original bean, so injecting by interface is safe.
Exchange this line:
@Autowired private MyCustomUserDetailsService myCustomUserDetailsService;for this one:
@Autowired private UserDetailsService myCustomUserDetailsService;Read the section on Proxying Mechanisms in the Spring AOP to understand the details.
所以在你的情况下，你可以用你需要的方法创建一个新的 interface CalendarRepository，然后在 class CalendarRepositoryImpl implements CalendarRepository:
interface CalendarRepository extends br.com.milo.repository.Repository<Calendar, Owner>{
void save(Calendar calendar);
void update(Calendar calendar);
void delete(Integer id);
... (and all other methods you need)
}
@Repository
class CalendarRepositoryImpl implements CalendarRepository {
... (what you currently have in CalendarRepository)
}
class CalendarController {
@Autowired
CalendarRepository repository; // NOT CalendarRepositoryImpl
}
