我的服务器端代码: -
@ApplicationPath("/externalpartnerws")
public class ExternalPartnerApplication extends javax.ws.rs.core.Application {
public Set<Class<?>> getClasses() {
return new HashSet<Class<?>>() { { add(ExternalPartnerApplicationResource.class); } };
}
}
@Path(value="/retrievetier2")
public class ExternalPartnerApplicationResource {
/**
* public constructor according to JSR-3.1.2 specification.
*/
public ExternalPartnerApplicationResource() {}
@GET
@Path("/bycountry/{distributorId}/{countryCd}")
// type "text/plain"
@Produces("application/xml")
public String retrieveTier2ByCountry(
@PathParam("distributorId") String distributorId,
@PathParam("countryCd") String countryCd
) {
if(distributorId == null && countryCd == null)
return null;
else //Moving logic from Controller to (Business) Model.
return "<?xml version=\"1.0\" encoding=\"UTF-8\"?><retrieveTier2ByCountry/>";
}

The following error occurred during the invocation of the handlers chain: 404 - Not Found with message ''null'' while processing GET request sent to ......
我在做任何基本错误吗?最近两天我花在这上面。 如果您需要更多信息,请与我们联系。
答案 0 :(得分:1)
看起来您的路径或路径模板错误。在您给出的示例中,您要将请求发送到以下路径(相对于您的应用程序根目录):
/bycountry/distributorId/2/countryCd/2
(即总共5个路径段:bycountry,distributorId,2,countryCd,2)
但是,资源上的模板显示:
/bycountry/{distributorId}/{countryCd}
(即只有3个路径段:bycountry,{distributorId},{countryCd})
这不匹配 - 所以你得到404。
您应该更改发送请求的网址,如下所示:
/bycountry/2/2
或者您应该将资源上的路径模板更改为:/bycountry/distributorId/{distributorId}/countryCd/{countryCd}
然后它应该工作。
