Question

我有一个使用Spring MVC开发的Web应用程序。此应用程序必须使用具有Spring注释的库中的bean：

@Service
public class DefaultSampleService implements SampleService {
    @Autowired SampleRepository sampleRepository;

    //Methods of service
}

我无法在我的应用程序中扫描这个bean所以，尽管有Spring注释，我必须通过库提供的工厂来实例化这个bean。

<beans>
    <bean id="libraryFactory" class="com.company.LibraryFactory" />

    <bean id="sampleService" factory-bean="libraryFactory" factory-method="getSampleService" />
</beans>

工厂返回一个sampleService bean，其中填充了sampleRepository属性。但是，当应用程序加载xml配置时，我得到一个NoSuchBeanDefinitionException，因为Spring没有找到SampleRepository的bean。

确实，Spring的beanFactory中没有SampleRepository bean。但我不需要它，因为sampleService由工厂实例化并且其属性被填充。

如何使用sampleService bean阻止自动装配过程？

我尝试将属性autowire =“no”添加到sampleService定义中，但它不起作用。

<bean id="sampleService" factory-bean="libraryFactory" factory-method="getSampleService" autowire="no" />

这是堆栈跟踪：

避免使用工厂创建的自动装配bean
