答案 0 :(得分：8)

  

引起：org.springframework.beans.factory.NoSuchBeanDefinitionException：找不到匹配的[com.bt.hqn.pcmservice.service.helper.ProductOfferingServiceHelper] 匹配的bean

Spring在上下文中找不到ProductOfferingServiceHelper类型的bean。你有一个名为pcmProductOfferingService的bean，它有：

@Autowired
private ProductOfferingServiceHelper productOfferingServiceHelper;

声明。确保：

  1. 宣布Bean：

      使用<bean/>注释或 在XML中使用
    2. 用例如注释使用@Service 或
      3. 扫描com.bt.hqn.pcmservice.service.helper和<context:component-scan/>包
    3. 由@Bean class
      4. 中使用@Configuration注释的方法返回

  2. 未宣布或创建两次（即两次上下文）;应该导致不同的错误消息，但以防万一

  3. 它未包含在AOP代理中（例如@Transactional）

答案 1 :(得分：0)

我的问题是我缺少上下文：我的应用程序上下文中的组件扫描。如果您正在进行自动接线，这一点非常重要。
