Spring MVC：“在名为“dispatcher”的 DispatcherServlet 中没有 [...] 映射”
有人可以帮助我吗？在 Spring MVC 中，我收到错误
- 警告：没有 [/TechBooks/details.htm] 的映射 名称为“dispatcher”的 DispatcherServlet
1) 首先，在 web.xml 中，我使用标准的 DispatcherServlet 来拦截所有 *.htm，这里没有什么不寻常的，这是预先编写的我：
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
2）在dispatcher-servlet.xml中，我使用SimpleUrlHandlerMapping，这也是标准的和预先编写的：
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="index.htm">indexController</prop>
</props>
</property>
</bean>
3）也在dispatcher-servlet.xml，我定义了名为“DetailsFormController”的 FormController 类，它映射到 details.htm：
<bean name="/details.htm" class="techbooks.web.DetailsFormController"/>
4）DetailsFormController 类是表单的 FormController。
package techbooks.web;
public class DetailsFormController extends SimpleFormController {
....
}
但是，当我执行资源 /details.htm 时，出现上述错误。
- 警告：[/TechBooks/details.htm] 中没有映射 名称为“dispatcher”的 DispatcherServlet
任何想法将不胜感激。谢谢。
Can someone help me. In Spring MVC I'm getting the error
- WARNING: No mapping for [/TechBooks/details.htm] in
DispatcherServlet with name 'dispatcher'
1) First of all, in web.xml, I use the standard DispatcherServlet which intercepts all *.htm, nothing unusual here, this was pre-written for me:
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
2) In dispatcher-servlet.xml, I am using the SimpleUrlHandlerMapping, again this is standard and pre-written:
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="index.htm">indexController</prop>
</props>
</property>
</bean>
3) Also in dispatcher-servlet.xml, I define my FormController class called "DetailsFormController", that maps to details.htm:
<bean name="/details.htm" class="techbooks.web.DetailsFormController"/>
4) And the class DetailsFormController is a FormController for a form.
package techbooks.web;
public class DetailsFormController extends SimpleFormController {
....
}
When I execute the resource /details.htm, however, I get the above error.
- WARNING: No mapping for [/TechBooks/details.htm] in
DispatcherServlet with name 'dispatcher'
Any ideas would be appreciated. Thanks.

您可以将 bean 定义更改为
或为 TechBooks 编写一个 urlmapping 处理程序吗
Can you change your bean difinition to
Or write a urlmapping handler for TechBooks
我发现问题是什么了。
使用 SimpleUrlHandlerMapping 时，控制器名称必须是 DetailsController，而不是 DetailsFormController，因此它会自动映射到正确的 JSP。
I found out what the issue was.
When using the SimpleUrlHandlerMapping, the Controller name has to be DetailsController, not DetailsFormController, so it maps automatically to the right JSP.
