我希望在Spring 4中使用Gson进行Web服务。我按照这篇教程中的步骤进行了操作。

在 SocialGraphUI.java 中获取请求方法。有一个名为 test 的对象和一个名为 allNodes 的方法,该方法返回类 Node 的对象列表,allEdges 返回类 Edge 的对象列表。
@RequestMapping(value = "/", method = RequestMethod.GET)
public String getNodesAndEdges(ModelMap model) {
model.addAttribute("nodes", test.allNodes);
model.addAttribute("edges", test.allEdges);
return "index";
}
I get these error messages:
type Exception report

description The server encountered an internal error that prevented it from fulfilling this request.
