java – Intellij Idea – 无法自动装配.找不到’ApplicationRep

我正在制作这个tutorial(Spring MVC Hibernate Tomcat)

到目前为止,一切都很好.当我尝试创建ApplicationController时,我无法自动装配ApplicationRepository.

部署应用程序时,我收到此错误消息和404错误代码：

Could not autowire. No beans of 'ApplicationRepository' type found. less...     
(Ctrl+F1) 
Checks autowiring problems in a bean class.

好的谈话很便宜.

编辑#1

我编辑了web.xml并添加了代码：

<web-app version="2.4"
    xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
    http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

    <display-name>Spring MVC Application</display-name>

    <servlet>
        <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
</web-app>

但是现在我得到了Element listener-class,不允许她来自Intellij IDEA.

我的应用程序甚至没有部署.

编辑#2

问题仍然存在.

我将persistance.xml重命名为persistence.xml.

重新启动Intellij的想法,仍然收到此错误.

也许这是一个错误？

我可能会投降这个春天的东西,它超出了我……
