将 bean 自动连接到我的控制器。防止使用 getBean 方法
Autowire the beans to my controller. Prevent use of getBean method
我正在尝试一个小型应用程序，但对 Spring mvc 框架还是很陌生。我有一个控制器 class 和一个 bean 配置 xml 文件。如果调用 getBean() 方法，我就可以使用该 bean。但是我的计划是使用自动装配将 bean 注入我的控制器中，而不是使用 getBean()。但我得到错误。我正在使用 maven 来构建我的项目。这是我的控制器 class 在 src/main/java
下的一个包中

// find the saved user again.

}
这是我在 src/main/resources

如果你想使用注释，组件扫描必须在你的配置中定义，你可以告诉spring哪个包需要这个自动扫描。
<context:component-scan base-package="com.xxx.xxx"/>
异常表示：排除了至少 1 个符合...的 bean，这意味着 spring 无法找到它。
如果你想将 bean 注入你的控制器，@Resource 比 @Autowired 好得多。因为
@Autowired
按类型注入。如果要按名称注入，则必须添加 @Qualifier() 注解。如果你使用 @Autowired，你必须确保依赖 bean 存在。如果允许为 null，则添加 @Autowired(required=false)。
我发现你的例外说
No qualifying bean of type [org.springframework.data.mongodb.core.MongoTemplate] found for dependency [org.springframework.data.mongodb.core.MongoTemplate]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoMatchingBeanFound(DefaultListableBeanFactory.java:1406)
检查你的 MongoTemplate bean，也许它根本不存在或者你的 spring 容器找不到它。
@Autowired()
@Qualifier("mongoTemplate")
private MongoTemplate mongoTemplate; // Autowired. Inject by type. if you want to inject by name, you must add @Qualifier() annotation.
@Resource
按名称注入。如果你想按名称注入
@Resource(name="mongoTemplate")
private MongoTemplate mongoTemplate; // Resource. Inject by name.
最重要的是@Resource属于J2EE，@Autowired属于Spring。两者都可以解决问题，但是
如果你弄清楚如何，你会更好。希望对您有所帮助。
您似乎只在 contextConfigLocation 参数中设置了配置文件 /WEB-INF/mvc-dispatcher-servlet.xml。将 baseConfig.xml 的内容添加到该内容，然后重试。如果这解决了问题，那么稍后，您可以设法使用多个配置文件。

如果你想使用注释，组件扫描必须在你的配置中定义，你可以告诉spring哪个包需要这个自动扫描。
<context:component-scan base-package="com.xxx.xxx"/>
异常表示：排除了至少 1 个符合...的 bean，这意味着 spring 无法找到它。
如果你想将 bean 注入你的控制器，@Resource 比 @Autowired 好得多。因为
@Autowired
按类型注入。如果要按名称注入，则必须添加 @Qualifier() 注解。如果你使用 @Autowired，你必须确保依赖 bean 存在。如果允许为 null，则添加 @Autowired(required=false)。
我发现你的例外说
No qualifying bean of type [org.springframework.data.mongodb.core.MongoTemplate] found for dependency [org.springframework.data.mongodb.core.MongoTemplate]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoMatchingBeanFound(DefaultListableBeanFactory.java:1406)
检查你的 MongoTemplate bean，也许它根本不存在或者你的 spring 容器找不到它。
@Autowired()
@Qualifier("mongoTemplate")
private MongoTemplate mongoTemplate; // Autowired. Inject by type. if you want to inject by name, you must add @Qualifier() annotation.
@Resource
按名称注入。如果你想按名称注入
@Resource(name="mongoTemplate")
private MongoTemplate mongoTemplate; // Resource. Inject by name.
最重要的是@Resource属于J2EE，@Autowired属于Spring。两者都可以解决问题，但是
如果你弄清楚如何，你会更好。希望对您有所帮助。
您似乎只在 contextConfigLocation 参数中设置了配置文件 /WEB-INF/mvc-dispatcher-servlet.xml。将 baseConfig.xml 的内容添加到该内容，然后重试。如果这解决了问题，那么稍后，您可以设法使用多个配置文件。
