Question

以下是我的Restful API的结构

@GET
@Path("/getprovider/{queryKey}/requests/{queryValue}")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response getApiProv(HttpServletRequest request,HttpServletResponse response,@PathParam("queryKey") String queryKey, @PathParam("queryValue") String queryValue) {
..........
..........
}

使用以下网址http://localhost:8080/v1/getprovider/service/requests/abc_demo

调用它

显示

HTTP ERROR 500
Problem accessing /v1/getprovider/service/requests/abc_demo
Reason:
java.io.EOFException: No content to map to Object due to end of input

我无法理解为什么它甚至不去方法体。请帮忙。

Answer 1

@Consumes(MediaType.APPLICATION_JSON)表示请求正文将包含一个有效的JSON对象，但错误消息表明您没有提供一个。您是否要添加@Consumes，如果是，您是否在请求正文中提供了JSON对象？

（请注意，GET的请求正文不受广泛支持，如果您实际上尝试使用该内容，那么您的终端可能不是幂等，是HTTP GET的一个关键属性。如果你真的想在请求体中使用JSON，那么你应该切换到@PUT或@POST）。

无法使用@PathParam在Jersey Rest中调用@GET
