Question

我使用Dropwizard获取这些缺少的依赖项错误：

ERROR [2013-07-31 22:17:01,918] com.sun.jersey.spi.inject.Errors: The following errors and warnings have been detected with resource and/or provider classes:
  SEVERE: Missing dependency for method public com.pronto.mpds.domain.MerchantProfileGroup com.pronto.mpds.service.MPDSResource.getMerchantProfiles(java.util.List,java.util.List) at parameter at index 0
  SEVERE: Missing dependency for method public com.pronto.mpds.domain.MerchantProfileGroup com.pronto.mpds.service.MPDSResource.getMerchantProfiles(java.util.List,java.util.List) at parameter at index 1

我的资源类看起来像这样：

@Path("merchants")
public class MPDSResource {

    @GET
    @Path("{merchantId}/profile")
    @Produces(APPLICATION_JSON)
    public MerchantProfile getMerchantProfile(@PathElem("merchantId") String merchantId) {
        throw new UnsupportedOperationException("not yet implemented");
    }

    @GET
    @Path("featured")
    @Produces(APPLICATION_JSON)
    public FeaturedMerchantGroup getFeaturedMerchants(@RequestParam(value = "browseId") String browseId) {
        throw new UnsupportedOperationException("not yet implemented");
    }

    @GET
    @Path("profile")
    @Produces(APPLICATION_JSON)
    public MerchantProfileGroup getMerchantProfiles(
            @RequestParam(value = "merchantIds", delimiter = "|") List<String> merchantIds,
            @RequestParam(value = "selectors", delimiter = "|") List<String> selectors) {
        throw new UnsupportedOperationException("not yet implemented");
    }

    @GET
    @Path("{merchantId}/cpc")
    @Produces(APPLICATION_JSON)
    public MerchantCpcData getMerchantCpcData(@PathElem("merchantId") String merchantId,
            @RequestParam(value = "mexpCategoryIds", delimiter = "|") Optional<List<String>> mexpCategoryIds) {
        throw new UnsupportedOperationException("not yet implemented");
    }
}

有四种方法，但错误只发生在采用多个参数的方法上。

我已经确认我在Maven导入中使用了一致的Jersey版本。我已经确认包含上述Resource类的Web模块在包含自定义PathElem和RequestParam类的包上包含Maven依赖项。我想不出任何其他可能性。有谁知道如何解决这个问题？

Answer 1

我还将这个问题发布到了dropwizard邮件列表，Coda Hale回答说：“你似乎将Spring MVC注释与Jersey混合在一起。我从来没有尝试过，但是如果有效的话，我会感到惊讶。我会建议使用标准的JAX-RS @PathParam和朋友。“ HTH别人。

Answer 2

我正在使用@FormParam。但将其更改为@RequestParam解决了这个问题。
