Question

我有两个请求网址

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

控制器中的映射是： -

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

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

问题： -

我的网址： - /domain/entity/list.vendorname

正在映射到 @RequestMapping(value = "/entity/list")

方法而不是另一方法。

请帮忙

Answer 1

原因是默认情况下，找到请求网址的映射的组件 - RequestMappingHandlerMapping，后缀匹配（/entity/list和/entity/list.*也被视为等效。修复可能是关闭后缀匹配：

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

但是，这也意味着您还必须手动注册handlerAdapter - 如果您使用<mvc:annotation-driven/>，则可以将其替换为以下内容：

<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>

从Spring 3.2开始，您还可以设置RequestMappingHandlerMapping bean的useRegisteredSuffixPatternMatch属性，以便激活后缀模式识别，但仅限于已注册的扩展名。

这里只定义json和xml扩展名：

<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>

请注意，mvc：annotation-driven现在接受contentNegotiation选项以提供自定义bean，但RequestMappingHandlerMapping的属性必须更改为true（默认为false）（参见https://jira.springsource.org/browse/SPR-7632）。

因此，您仍然必须覆盖所有mvc：annotation驱动的配置。我打开了一张Spring的票，要求自定义RequestMappingHandlerMapping：https://jira.springsource.org/browse/SPR-11253。如果您有兴趣，请投票。

在覆盖时，请注意自定义执行管理覆盖。否则，所有自定义异常映射都将失败。您必须将messageCoverters与list bean重用：

<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>
