在名称为“ [重复] 的 DispatcherServlet 中未找到带有 URI [] 的 HTTP 请求的映射

Question

早上，我已经检查了这个问题 (No mapping found for HTTP request with URI.... in DispatcherServlet with name) 和 (No mapping found for HTTP request with URI [/ChickenTest/index] in DispatcherServlet with name 'dispatcherServlet') 的大部分答案，但我仍然收到“找不到带有 URI [/bmoa-surrounds/bmoa] 的 HTTP 请求的映射]在名为 'bmoa' 的 DispatcherServlet 中，因此，任何帮助都值得赞赏：

然后是我的 web.xml

<display-name>bmoa-surrounds</display-name>

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

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

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

    <servlet-mapping>
        <servlet-name>bmoa</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>


    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

我的弹簧配置文件

<context:component-scan base-package="xxxx"/>
    <context:annotation-config/>
    <context:spring-configured/>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

最后是我的控制器

@Controller
public class BMOAServlet implements HttpRequestHandler {


    /**
     * 
     */
    @RequestMapping("/bmoa-surrounds/bmoa")
    public void handleRequest(final HttpServletRequest request,
            final HttpServletResponse response) throws ServletException,
            IOException {

         response.getWriter().write("result=" + handleIncomingMessage(request));
    }

我正在调用“http:// localhost :8080/bmoa-surrounds/bmoa?juan=9898”，但在 DispatcherServlet 中仍然没有找到带有 URI [/bmoa-surrounds/bmoa] 的 HTTP 请求的映射名称为“bmoa”，有什么想法吗？我的环境是 java6 a 部署到 jboss

我也确定 bean 已加载，我在服务器日志中得到了这个

12:34:06,671 INFO  [org.springframework.beans.factory.support.DefaultListableBeanFactory] (MSC service thread 1-5) Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@57ffa0: defining beans [BMOABussinesDelegate,properties,BMOAServlet,.........]; parent: org.springframework.beans.factory.support.DefaultListableBeanFactory@122d7c6

还有这个

12:34:06,753 INFO  [org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping] (MSC service thread 1-5) Mapped URL path [/bmoa-surrounds/bmoa] onto handler 'BMOAServlet' 12:34:06,754 INFO  [org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping] (MSC service thread 1-5) Mapped URL path [/bmoa-surrounds/bmoa.*] onto handler 'BMOAServlet' 12:34:06,755 INFO  [org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping] (MSC service thread 1-5) Mapped URL path [/bmoa-surrounds/bmoa/] onto handler 'BMOAServlet'

最后一个是否意味着映射已加载？请帮忙;(

Answer 1

我现在感觉真的很愚蠢....起初（感谢 Angad 的线索），url 模式是错误的，它应该指向 servlet，而且加载的 bean 是 BMOAServlet 而不是 bmoa ，所以当我更改 url-patter no bmoa 时，设法看到错误，最后我的 web.xml 需要看起来像这样：

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

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

     <servlet>
        <servlet-name>bmoa</servlet-name>
        <servlet-class>org.springframework.web.context.support.HttpRequestHandlerServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>bmoa</servlet-name>
        <url-pattern>/bmoa</url-pattern>
    </servlet-mapping>


    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

还有这样的 bean 类：

@Controller("bmoa")
public class BMOAServlet implements HttpRequestHandler {



    /**
     * 
     */
    @RequestMapping("/bmoa-surrounds/bmoa")
    public void handleRequest(final HttpServletRequest request,
            final HttpServletResponse response) throws ServletException,
            IOException {

         response.getWriter().write("result=" + handleIncomingMessage(request));
    }

现在一切顺利，我还像这样更改了 servlet 类：

<servlet>
        <servlet-name>bmoa</servlet-name>
        <servlet-class>org.springframework.web.context.support.HttpRequestHandlerServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

Answer 2

检查这个配置文件：src\main\webapp\WEB-INF\spring\appServlet\controllers.xml

内容如下：

<context:component-scan base-package="org.springframework.samples.mvc" />

你的控制器在“org.springframework.samples.mvc”中吗？

在 pom.xml 中确保将包装设置为 war 就像 <packaging>war</packaging> 一样，而不是 jar 或其他任何东西。
