如何在Spring MVC控制器的@RequestMapping路徑中限制路由擴展？

Question

我有一個相當簡單的任務，我想完成，但似乎無法找到有關Spring MVC路由的信息。我有一個非常簡單的控制器的路由到一個視圖的路徑：

@Controller 
@RequestMapping(value = "/help") 
public class HelpController { 

    private static final String HELP = "help"; 

    @RequestMapping(method = RequestMethod.GET) 
    public String help(Model model, Locale locale) { 
     model.addAttribute("locale", locale); 
     return HELP; 
    } 
} 

我想拋出一個404，如果http://mysite.com/help.some.extension.is.entered，但春天似乎解決了/幫助的例子。 javadoc說@RequestMapping註釋只是一個servlet URI映射，但我認爲/幫助意味着它需要完全匹配。任何澄清將不勝感激。

Answer 1

您可以在@RequestMapping註解

是相同的，因爲只有Servlet的URL模式提到它。

@Controller 
public class HelpController { 

    private static final String HELP = "help"; 

    @RequestMapping(value = "/help" method = RequestMethod.GET) 
    public String help(Model model, Locale locale) { 
     model.addAttribute("locale", locale); 
     return HELP; 
    } 

    @RequestMapping(value = "help/*" method = RequestMethod.GET) 
    public String helpWithExtraWords() { 
     return "error"; 
    } 
}

我能想到的最好的辦法是明確地配置您的RequestMappingHandlerMapping不考慮suffixpaths，這種方式：

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

但是，如果你已經使用mvc:annotation-driven配置你的Spring MVC，這不會工作，你將不得不展開整個處理適配器的定義，這是不難做到的（這不是完整的，你可以查看整個定義的org.springframework.web.servlet.config.AnnotationDrivenBeanDefinitionParser）：

<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 name="validator"> 
       <bean class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/> 
      </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> 

<bean name="handlerMapping" class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"> 
    <property name="useSuffixPatternMatch" value="false"></property> 
</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="conversionService" ref="conversionService"></property> 
      <property name="validator"> 
       <bean class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/> 
      </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> 

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

Answer 3

使用Spring 3.0.X您可以使用useDefaultSuffixPattern屬性。

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"> 
    <property name="useDefaultSuffixPattern" value="false" /> 
</bean> 

你將需要刪除</mvc:annotation-driven>

參考URL Pattern Restricting in SPRING MVC

Answer 4

春天4這是很容易解決：

<mvc:annotation-driven> 
    <mvc:path-matching suffix-pattern="false" /> 
</mvc:annotation-driven> 

所以，你仍然可以使用mvc:annotation-driven爲你的配置。
