java - 无法 Autowiring 方法

Question

我收到这个错误

org.springframework.beans.factory.BeanCreationException: 
Could not autowire method:

这是我的spring的xml配置。

<bean ...>   
...
    <property name="InfoModel" ref="InfoModel"></property>
</bean>

这是我在 Java 类中 Autowiring 它的代码

  private InfoModel infoModel;

  @Autowired
  public void setInfoModel(InfoModel infoModel) {
    this.infoModel= infoModel;
  }

我是不是漏掉了什么。我怀疑我应该制作 InfoModel 的 Interface 以使其 Autowiring ？

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.model.InfoModel] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

Answer 1

如果您使用@Autowired，则无需在 xml 中将其标记为属性。只需将 InfoModel 声明为 XML 中的 bean 并从 xml 中删除 property 为你注入(inject) InfoModel

的 bean

总结

1 您需要在 XML 中为 InfoModel

定义一个 bean

2 您需要从 XML 中删除 property

3 确保您已通过添加

来驱动上下文注释

<context:annotation-config />
