自动连线依赖项的注入失败了嵌套异常



我正在尝试部署 Map Portlet，这是一个弹簧 MVC 框架工作。部署时出现错误，如下所示。

13:57:25,966 ERROR [org.springframework.web.portlet.DispatcherPortlet] (ServerService Thread Pool -- 146) Context initialization failed: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mapViewController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void org.jasig.portlet.maps.mvc.portlet.MapViewController.setMapDao(org.jasig.portlet.maps.dao.IMapDao); nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.jasig.portlet.maps.dao.IMapDao] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

它们是RestfulJsonMapDaoImpl类的@Autowired，该类具有接口类IMapDao。

我不知道我哪里出了问题，但错误是连续且相同的。如果有人提前解决这个问题，这对我有很大帮助，谢谢。

我认为您的应用程序中缺少以下代码片段.xml 

<mvc:annotation-driven />

以及 servlet 上下文中的相应命名空间。

Spring 在标签中定义的包中搜索 bean 

<context:component-scan base-package="org.jasig.portlet" />

由于标签，它能够使用@Controller或@RequestMapping等注释

<mvc:annotation-driven />

我认为您需要两者：

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
    ...
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context ...">
    ...
    <context:component-scan base-package="org.jasig.portlet" />
    <mvc:annotation-driven />
...
</beans>

尝试允许 Spring 扫描您的软件包以自动连线：

您的应用程序.xml应包含：

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:context="http://www.springframework.org/schema/context"
   xsi:schemaLocation="
    ...
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context ...">
    ...
    <context:component-scan base-package="org.jasig.portlet" />
...
</beans>

尝试在applicationContext XML文件中使用它。 组件扫描应该是根包。 <context:component-scan base-package="org.jasig" />
