Question

我正在尝试以JSON格式向Rest服务发送请求。当我发送请求时：

http://localhost:8080/MyProject/MyPackage/hello/{"no":"12","op":"read"}

它工作正常，但是当我尝试发送数组以及其他参数时：

http://localhost:8080/MyProject/MyPackage/hello/{"no":"12","op":"read","attributes":[{"name"},{"id"}]}

这里我得到的错误是：

休息服务类就像这样

public class RestService {
    private static final Logger LOGGER = Logger.getLogger(RestService.class.getName());
    @GET
    @Path("/{param}")
    @Consumes("text/plain")
    @Produces("application/json")
    public String readJSON(@PathParam("param") String json) {
    //doing mytask
}

在第一种情况下，上述功能的主体是可访问的，但在2种情况下它甚至没有进入功能体。

这个错误的根本原因是什么？

在请求中使用JSON数组来休息服务
