java - BeanNotOfRequiredTypeException : Bean named X is expected to be of type X but was actually of type 'com. sun.proxy.$Proxy

Question

我有这样的类和 Spring 上下文。

如何修复这个错误的 Java 配置，而不是 xml？

我尝试了其他帖子中的一些解决方案，但没有成功。

@Service
@Transactional
public class XCalculationService implements VoidService<X> {
}

public interface VoidService<Input> {
}

@AllArgsConstructor
public class XService {
private XCalculationService calculationService;
}

@Configuration
public class ServiceConfiguration {
@Bean
public OrderService orderService(XCalculationService calculationService) {
    return new XService(calculationService);
}

@Bean
public XCalculationService calculationService() {
    return new XCalculationService ();
}
}

错误

BeanNotOfRequiredTypeException: Bean named 'calculationService' is expected to be of type 'com.x.XCalculationService' but was actually of type 'com.sun.proxy.$Proxy

Answer 1

这是 100% 修复:

@EnableTransactionManagement(proxyTargetClass = true)
