java - Spring RestClient 内容类型不匹配

Question

我正在尝试使用 Terremark 企业云中的 REST Web 服务之一。这是我所做的:1)获取xsd并生成jaxb工件2) 发送 Rest 调用并让 Restclient 填充 Organizations 类。

ResponseEntity exchange = template.exchange("https://services.enterprisecloud.terremark.com/cloudapi/ecloud/organizations/", 
                    HttpMethod.GET, 
                    new HttpEntity(operation.getInput(), operation.getHeader()), 
                    Organizations.class, 
                    urlVariables);

我看到的错误是

org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type [com.dto.Organizations] and content type [application/vnd.tmrk.cloud.organization;type=collection]

在上述错误中，com.dto.Organizations 是由 JAXB 生成的 java 类。任何解决此问题的通用 Spring 指针也会有所帮助。

附注在 Spring 调度程序中，我有以下内容:

<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
    <property name="messageConverters">
        <list>
           <bean id="marshallingHttpMessageConverter" 
            class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter"
            p:marshaller-ref="jaxb2Marshaller" p:unmarshaller-ref="jaxb2Marshaller" />
            <bean class="org.springframework.http.converter.StringHttpMessageConverter"/>
            <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"/>
            <bean class="org.springframework.http.converter.ResourceHttpMessageConverter"/>
        </list>
    </property>
</bean>

Answer 1

我相信您需要设置由您的 MarshallingHttpMessageConverter 处理的内容类型:

...
<bean id="marshallingHttpMessageConverter" 
        class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter"
        p:marshaller-ref="jaxb2Marshaller" p:unmarshaller-ref="jaxb2Marshaller" 
        p:supportedMediaTypes="application/vnd.tmrk.cloud.organization"/>
...

...类似的东西。 MarshallingHttpMessageConverter 默认支持的媒体类型就是 application/*+xml。
