This question already has answers here:

Why does Spring MVC respond with a 404 and report “No mapping found for HTTP request with URI […] in DispatcherServlet”?

早上，我已经检查了该问题的大多数答案(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')，但是我仍然收到“在DispatcherServlet中名称为'bmoa'的URI [/bmoa-surrounds/bmoa]的HTTP请求中未找到映射。 ”，因此，任何需要帮助的人:

然后我的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 Spring 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 Controller

@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中名称为“'的URI [/bmoa-surrounds/bmoa]的HTTP请求中仍找不到任何映射。 bmoa'，有什么想法吗？我的环境是java6 a部署到jboss

还我确定bean是良性加载的，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'

最后一个不是表示已加载映射吗？请帮忙 ;(

最佳答案

我现在真的感觉很蠢。...(首先感谢Angad的提示)，url-pattern错误，它应该指向servlet，而且，加载的bean是BMOAServlet而不是bmoa，所以当我更改了url-patter no bmoa，设法看到了错误，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>

和这样的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));
    }

现在一切正常，我还更改了servlet类，如下所示:

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