春天@RequestMapping不工作如果在URL擴展

Question

我有兩個URL請求

/domain/entity/list.vendorname /域/實體/列表

在控制器的映射預期： -

@RequestMapping(value = "/entity/list.{vendorId}") 

@RequestMapping(value = "/entity/list") 

問題： -

我的URL： - /domain/entity/list.vendorname

正被映射到 @RequestMapping(value = "/entity/list")

方法而不是另一個。

請幫幫

Answer 1

原因是默認指找到用於請求URL的映射組件 - RequestMappingHandlerMapping，上後綴還（/entity/list和/entity/list.*被認爲是等價的修復可以是轉動後綴匹配關閉匹配。：

<bean name="handlerMapping" class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"> 
    <property name="useSuffixPatternMatch" value="false"></property> 
</bean> 

然而，這也意味着你將不得不手動註冊的HandlerAdapter也 - 如果你使用<mvc:annotation-driven/>你可以沿着這些路線的東西替代它：

<bean name="handlerAdapter" class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"> 
    <property name="webBindingInitializer"> 
     <bean class="org.springframework.web.bind.support.ConfigurableWebBindingInitializer"> 
      <property name="conversionService" ref="conversionService"></property> 

      </property> 
     </bean> 
    </property> 
    <property name="messageConverters"> 
     <list> 
      <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter"></bean> 
      <bean class="org.springframework.http.converter.StringHttpMessageConverter"></bean> 
      <bean class="org.springframework.http.converter.ResourceHttpMessageConverter"></bean> 
      <bean class="org.springframework.http.converter.xml.SourceHttpMessageConverter"></bean> 
      <bean class="org.springframework.http.converter.xml.XmlAwareFormHttpMessageConverter"></bean> 
      <bean class="org.springframework.http.converter.xml.Jaxb2RootElementHttpMessageConverter"></bean> 
      <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"></bean> 
     </list> 
    </property> 
</bean>

從Spring 3.2開始，您還可以設置RequestMappingHandlerMapping bean的useRegisteredSuffixPatternMatch屬性，以便激活後綴模式識別，但僅限於註冊擴展。

在這裏，你只定義了JSON和XML擴展：

<bean id="handlerMapping" 
     class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"> 
    <property name="contentNegotiationManager" ref="contentNegotiationManager"/> 
    <property name="useRegisteredSuffixPatternMatch" value="true"/> 
</bean> 

<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean"> 
    <property name="favorPathExtension" value="false"/> 
    <property name="favorParameter" value="true"/> 
    <property name="mediaTypes"> 
     <value> 
      json=application/json 
      xml=application/xml 
     </value> 
    </property> 
</bean> 

需要注意的是MVC：註解驅動現在接受contentNegotiation選項提供自定義的bean，但RequestMappingHandlerMapping的財產已被更改爲true（默認假）（參見https://jira.springsource.org/browse/SPR-7632）。

因此，您仍然必須重寫所有mvc：註釋驅動的配置。我打開了Spring的門票以請求自定義的RequestMappingHandlerMapping：https://jira.springsource.org/browse/SPR-11253。請投票，如果你有興趣。

重寫時，要小心也考慮自定義執行管理覆蓋。否則，您所有的自定義異常映射都將失敗。你將有一個列表豆重用messageCoverters：

<util:list id="messageConverters"> 
    <bean class="your.custom.message.converter.IfAny"></bean> 
    <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter"></bean> 
    <bean class="org.springframework.http.converter.StringHttpMessageConverter"></bean> 
    <bean class="org.springframework.http.converter.ResourceHttpMessageConverter"></bean> 
    <bean class="org.springframework.http.converter.xml.SourceHttpMessageConverter"></bean> 
    <bean class="org.springframework.http.converter.xml.XmlAwareFormHttpMessageConverter"></bean> 
    <bean class="org.springframework.http.converter.xml.Jaxb2RootElementHttpMessageConverter"></bean> 
    <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"></bean> 
</util:list> 

<bean name="exceptionHandlerExceptionResolver" 
     class="org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver"> 
    <property name="order" value="0"/> 
    <property name="messageConverters" ref="messageConverters"/> 
</bean> 

<bean name="handlerAdapter" 
     class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"> 
    <property name="webBindingInitializer"> 
     <bean class="org.springframework.web.bind.support.ConfigurableWebBindingInitializer"> 
      <property name="validator"> 
       <bean class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/> 
      </property> 
     </bean> 
    </property> 
    <property name="messageConverters" ref="messageConverters"/> 
</bean> 

<bean id="handlerMapping" 
     class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"> 
    <property name="contentNegotiationManager" ref="contentNegotiationManager"/> 
    <property name="useRegisteredSuffixPatternMatch" value="true"/> 
</bean> 

<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean"> 
    <property name="favorPathExtension" value="false"/> 
    <property name="favorParameter" value="true"/> 
    <property name="mediaTypes"> 
     <value> 
      json=application/json 
      xml=application/xml 
     </value> 
    </property> 
</bean>
