内容传送服务报告"无法检索所需结果".

Question

在使用Web浏览器测试我的Tridion内容交付Web服务时,我可以通过调用"http://webservice/odata.svc/"成功获取可用集合的列表,但是当我尝试访问其中一个集合时,例;

http://webservice/odata.svc/Publications

我明白了

<message xml:lang="en-US">Unable to retrieve desired results.</message>

或特定项目

http://webservice/odata.svc/Publications(19)

我明白了:

<message xml:lang="en-US">Unable to build publication entry: 
                             Unable to retrieve desired results.</message>

在日志中,我得到以下内容(我删除了时间戳等,使其更具可读性):

FilterValue - value: 25 is Integer
JPQLExecutor - JPAQueryDAO has not been instantiated. Probably FS storage type was used.

此消息指向我的存储配置,但是我无法在文档中找到有关如何设置它以支持Web服务的任何明确指导.

我的存储应该如何配置？期望为服务和网站设立单独的部署者是否正常？我应该考虑哪些其他问题？

CD Web服务要求您的所有内容都在CD DB中.这对文件系统没有任何意义.如果你的FS上还有东西,那么CD Web服务的某些部分将无法正常工作.例如,考虑可能在FS上的页面 - 您将无法通过CD Web服务检索PageContent.

对于您的问题,请检查您的CD Webservice cd_storage_conf.xml是否定义了数据库(JPA)连接.当然它是功能性的.检查通常的嫌疑人,数据库连接,用户,通行证,网址,JAR ...

编辑:仔细查看堆栈跟踪,您必须将FS定义为默认存储介质(由于getOriginalDAO(...)产生a FSDAOFactory.getDAOForTypeMapping(...)).所以我认为这是问题的根源.还要检查您的许可证是否有效,以及由于缺少/过期的CD许可证,您的"绑定"未恢复为FS.
