我正在使用Spring @ MVC3，我遇到了问题。 Spring bean已创建，但@Autowired在类中不起作用。这是我的设置和源代码：

问题bean是mediaDao。但它是在Spring容器中创建的。这是问题正在发生的Java源代码。

mediaDao为null，但@Autowired的其他Java源代码都可以。我不知道遗失了什么？

3 个答案:

答案 0 :(得分：0)

您没有扫描类的包，因此注释将被忽略。将其包添加到组件扫描元素中，就像您已经为控制器包做的那样。

答案 1 :(得分：0)

我的想法是，你是否用@Service注释注释了服务，如果没有，那么spring不会认为它是Spring托管类，它可能不会为你注入DAO。它应该是服务或组件注释。另外，Dave告诉包装是否按照弹簧上下文扫描包装。您已为控制器包提供了组件扫描。我不确定MediaService是否也放在同一个包中。只需检查所有这些因素。

答案 2 :(得分：0)

以下是正确的表格。

@Autowired private MediaDaoInterface mediaDaoInt;
