春季数据库配置问题

Question

我是新来Spring-MVC，我试图创建在controller使用annotation一个Spring-MVC项目，也创造databases。

应用程序工作正常，当我在spring-dispatcher-servlet.xml文件写所有的xml代码，但是当我分开spring database connection xml和spring servlet xml文件，它停止工作。

下面的代码创建成功数据库表中，但它不能负载控制器，它给了我404 not found页时，我尝试打任何控制器。 如果我在web.xml文件注释<listner>代码它成功加载所有的控制器，但没有执行数据库操作。

请指导我我在做什么错在这里。

的web.xml

<!-- JPA --> 
    <listener> 
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
    </listener> 
    <context-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value>/WEB-INF/spring.xml</param-value> 
    </context-param> 



<!-- Servlet Dispatcher --> 
    <servlet> 
     <servlet-name>spring-dispatcher</servlet-name> 
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 

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

    <servlet-mapping> 
     <servlet-name>default</servlet-name> 
     <url-pattern>*.css</url-pattern> 
    </servlet-mapping> 

Spring.xml

<mvc:annotation-driven />

    <tx:annotation-driven transaction-manager="transactionManager" /> 

</beans> 

弹簧调度-servlet.xml中

你需要添加上下文：组分扫描基包=“控制器封装”在调度的servlet XML，使其工作。 扫描软件包并注册您的控制器类需要组件扫描
