在名称为“dispatcher”的 DispatcherServlet 中找不到带有 URI [/st/test.htm] 的 HTTP 请求的映射

Question

我正在尝试使用 spring 框架并且是新手。 使用 nebeans 在我的 Spring 应用程序中获取以下日志

Nov 27, 2012 8:20:16 PM org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/st/test.htm] in DispatcherServlet with name 'dispatcher'

我使用 netbeans 创建了应用程序，它为我创建了所有默认配置，如下所示。

调度程序-servlet

    <!--
    Most controllers will use the ControllerClassNameHandlerMapping above, but
    for the index controller we are using ParameterizableViewController, so we must
    define an explicit mapping for it.
    -->
    <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <props>
                <prop key="index.htm">indexController</prop>
            </props>
        </property>
    </bean>

    <bean id="viewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          p:prefix="/WEB-INF/jsp/"
          p:suffix=".jsp" />

    <!--

    -->
    <bean name="indexController"
          class="org.springframework.web.servlet.mvc.ParameterizableViewController"
          p:viewName="index" />

</beans>

应用上下文

    <!-- ADD PERSISTENCE SUPPORT HERE (jpa, hibernate, etc) -->

</beans>

我的控制器（在默认包中，（src 文件夹根目录））

@Controller
@RequestMapping(value="test")
public class TstCnt {


    public String tst(){
        return "aks";
    }
}

网址命中

http://localhost:8084/st/test.htm

Answer 1

尝试将控制器映射更改为此：

 @Controller
 @RequestMapping("/st")
 public class TstCnt {

 @RequestMapping(value = "/test", method = RequestMethod.GET)      
 public String tst(){
     return "test";
   }
 }

并确保web.xml 包含 Dispatcher servlet 的映射，如下所示：

<servlet-mapping>
    <servlet-name>DispatcherServlet</servlet-name>
    <url-pattern>*.htm</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>DispatcherServlet</servlet-name>
    <url-pattern>*.html</url-pattern>
</servlet-mapping> 

Answer 2

尝试将控制器映射更改为此：

 @Controller

 public class TstCnt {

 @RequestMapping(value = "/st/test")      
 public String tst(){
     return "test";
   }
 }
