我已经为此工作了一段时间，根本不知道出了什么问题。我正在 Tomcat 7 上部署 Spring 3.1 MVC 应用程序。通过查看 DEBUG 输出，我可以看到 1）MVC 调度程序 servlet 根据需要获取我的所有 URL 2）映射到控制器注释的任何 URL 都可以正常工作 3）任何 URL需要映射到 JSP 得到 404。另外，我使用的是 JDK 1.7.0_09。我的 JSP 页面位于 /WEB-INF/jsp/ 中。

提前感谢我可能遗漏的任何提示！

这是我的 web.xml：

    <?xml version="1.0" encoding="UTF-8"?>
<web-app 
    id="WebApp_ID" 
    version="2.5" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="
        http://java.sun.com/xml/ns/javaee 
        http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <display-name></display-name>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
    </context-param>

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

    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

我尝试将我的 URL 模式修改为 /、/ 、/。, . “/”似乎是我迄今为止最远的地方。另外，我可能是错的，但我不认为 URL 是问题，因为调试日志显示所有 URL 都将发送到调度程序 servlet——这正是我想要的。

这是我的调度程序-servlet.xml：

<?xml version="1.0" encoding="UTF-8"?>

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <!--JSR-303 (Bean validation) support will be detected on classpath and enabled automatically-->
    <mvc:annotation-driven />

    <!--This tag allows for mapping the DispatcherServlet to "/" (all extensions etc)-->

    <!-- ControllerClassNameHandlerMapping -->

        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <bean class = "org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping" />
    <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter" />
</beans>

我尝试通过http://localhost:8080/hello. 我的应用程序被部署到“/”并且解析器没有将“/home”视图映射到/WEB-INF/jsp/hello.jsp，尽管调试日志显示它正确地确认“/home”是传入视图姓名。

http://localhost:8080/rest/user/bob_user效果很好，并映射到 Controller 注释。

任何帮助将不胜感激！谢谢！

更新：以下是http://localhost:8080/hello应转换为 /WEB-INF/jsp/hello.jsp的调试日志

也许您的 mvc:annotation-driven 正在覆盖您的 RequestMappingHandlerMapping。

还要从组件扫描中排除 @Controller 类：

<context:component-scan base-package="org.example">
    <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

因为控制器已经被

所以.. 我通过创建一个新的 Controller 类来解决这个问题，该类的方法带有@RequestMapping("/{viewName}"). Spring MVC 的匹配方式，这应该是最后也是最通用的匹配。结果，如果我得到 URL，它将尝试首先匹配其他控制器，然后最后匹配这个。当它匹配时，我只返回一个带有视图名称的字符串，所以它最终会转到/WEB-INF/jsp/[view-name].jsp. 有人有更好的主意吗？谢谢！
