Question

我已经在一个侧面项目工作了一段时间，我仍然对spring框架有些新意。我注意到当我在tomcat服务器上编译Web应用程序时，永远不会识别请求映射。我已经确保正在使用组件扫描xml标签，但我不确定在哪里可以查找为什么它们没有被加载。这是github项目的链接：

http://github.com/dmcquillan314/YouthMinistryHibernate.git

根据要求，这是我的web.xml

<web-app id="WebApp_ID" 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">

和我的spring-mvc.xml文件

    <mvc:annotation-driven/>

    <context:component-scan base-package="com.youthministry.controller"  />

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

            <value>/WEB-INF/jsp/</value>
        </property>

        <property name="basenames">
            <list>
                <value>message</value>
            </list>
        </property>
    </bean>

</beans>

如果我需要进一步发布，请告诉我。

非常感谢任何帮助。提前谢谢。

我无法检查您的本地问题的项目，下面的链接解释了您可能使用的不同类型的配置标记，例如mvc:annotation-drive ,context component-scan等。

Different Spring Annotation XML Declarations

我还建议您将log4j添加到项目中，然后将日志级别设置为debug。因此，当您启动项目时，它可以打印出@RequestMapping中的所有URL，当您向服务器发送请求时，它还可以打印出您发送的URL，这样您就可以轻松找到问题。

Answer 2

您的web.xml是什么样的？（也许你可以直接在这篇文章上发布相关的配置文件....）必须指定路径“拾取”。

http://static.springsource.org/spring/docs/3.2.x/spring-framework-reference/html/mvc.html

<web-app>

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

  <servlet-mapping>
    <servlet-name>example</servlet-name>
    <url-pattern>/example/*</url-pattern>
  </servlet-mapping>

</web-app>

查看上下文xml文件，添加了组件扫描标记。但是缺少一个标签，使应用程序能够读取注释。

<annotation-driven/>

<context:component-scan base-package="com.youthministry.controller" />

尝试添加缺少的标记。
