我正在用 Spring 构建非常基本的 mvc 应用程序。它有一个控制器，应该在请求正文上调用验证。问题是，如果我在 web.xml 中定义映射，它会停止寻找正确的控制器，但是当我修改 servlet 应用程序上下文时，Spring 星会即时进行一些新的绑定，但是这次基于注释的验证被忽略了。如何在仍然调用基于注释的验证的同时控制 web.xml 中的映射？
以下是详细信息：
控制器：
@Controller
@RequestMapping("/api")
public class UserActionsController {
@RequestMapping(value="/choice", method = RequestMethod.POST)
public @ResponseBody NameValue addUserChoice(@Valid @RequestBody NameValue action)
{
return action;
}
}
这是 servlet 应用程序上下文：
<mvc:annotation-driven/>
<context:component-scan base-package="com.my.package" />
<bean
class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<property name="mediaTypes">
<map>
<entry key="json" value="application/json" />
</map>
</property>
<property name="defaultContentType" value="application/json" />
<property name="defaultViews">
<list>
<bean
class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" />
</list>
</property>
</bean>
网页xml：
<servlet>
<servlet-name>action-api</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>action-api</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
上面的配置正在运行。当我尝试更改 web.xml 时问题就开始了，因此控制器将只负责“/api/*”。我将其更改为<url-pattern>/api/*</url-pattern>. 在这种情况下，Spring 找不到合适的控制器。
(DispatcherServlet:819) - DispatcherServlet with name 'action-api' processing POST request for [/api/choice]
(RequestMappingHandlerMapping:209) - Looking up handler method for path /choice
(RequestMappingHandlerMapping:219) - Did not find handler method for [/choice]
(PageNotFound:1080) - No mapping found for HTTP request with URI [/api/choice] in DispatcherServlet with name 'action-api'
(DispatcherServlet:913) - Successfully completed request
修改 servlet 应用程序上下文会有所帮助，Spring 现在能够找到控制器，但不再调用验证。
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="alwaysUseFullPath" value="true" />
<property name="messageConverters">
<util:list id="beanList">
<bean class="org.springframework.http.converter.StringHttpMessageConverter"/>
<bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"/>
</util:list>
</property>
</bean>
<bean
class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="alwaysUseFullPath" value="true" />
</bean>
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="alwaysUseFullPath" value="true" />
</bean>
这是日志：
(DispatcherServlet:819) - DispatcherServlet with name 'action-api' processing POST request for [/api/choice]
(RequestMappingHandlerMapping:209) - Looking up handler method for path /choice
(RequestMappingHandlerMapping:219) - Did not find handler method for [/choice]
(DefaultAnnotationHandlerMapping:124) - Mapping [/api/choice] to HandlerExecutionChain with handler [com.my.package.controller.UserActionsController@1f86dbd] and 1 interceptor
(HandlerMethodInvoker:638) - Reading [com.my.package.model.NameValue] as "application/json" using [org.springframework.http.converter.json.MappingJacksonHttpMessageConverter@2059ef]
(HandlerMethodInvoker:173) - Invoking request handler method: public com.my.package.model.NameValue com.citypath.dima.controller.UserActionsController.addUserChoice(com.my.package.model.NameValue)
(AnnotationMethodHandlerAdapter:1037) - Written [com.my.package.model.NameValue@166685b] as "application/json;charset=UTF-8" using [org.springframework.http.converter.json.MappingJacksonHttpMessageConverter@2059ef]
(DispatcherServlet:957) - Null ModelAndView returned to DispatcherServlet with name 'action-api': assuming HandlerAdapter completed request handling
(DispatcherServlet:913) - Successfully completed request
看起来 Spring 进行了一些即时绑定，但这次验证器被忽略了。我需要有 2 个控制器，比如“/api”和“/something”。如何在 web.xml 中定义它，以便 Spring 能够找到它们并调用验证？
谢谢。
