使用 java spring 从另一台服务器获取 API 数据的代理代码/应用程序

Question

I have to get data from an API which the response is JSON file, but the API server doesn't allow client Access, therefor I have to make a proxy code in JAVA order JAVA Spring to get the data from the API Server and return the响应，我在 c# 中做到了：

namespace Proxy.Controllers
{
    public class AutoCompleteController : ApiController
    {
        // GET api/AutoComplete
        public IRestResponse Get(string term)
        {
            var client = new RestClient("API Link" + term);
            //client.Timeout = -1;
            var request = new RestRequest(Method.GET);
            if (this.Request.Headers.Contains("session name"))
                request.AddHeader("session name", this.Request.Headers.GetValues("X-Autocomplete-Session").First());
            request.AddHeader("Authorization", "some infos");
            IRestResponse response = client.Execute(request);
            Console.WriteLine(response.Content);
            return response;          
        }
    }
}

和配置

namespace Proxy
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            var cors = new EnableCorsAttribute("*", "*", "*");
            config.EnableCors(cors);
            // Web API configuration and services

            // Web API routes
            config.MapHttpAttributeRoutes();

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );
        }
    }
}

它工作得很好但是，现在我必须在 JAVA 中重写它，你能帮我做一个应用程序吗？

ps 我将在前端使用 jQuery 中的数据
