java - 在java中将JSON从ajax请求转换为JSON对象

Question

这是表单数据

selectedDtlId: [{"id":"3","isReviewed":true,"notes":"notes asdf test add 2"},{"id":"2","isReviewed":true,"notes":""},{"id":"1","isReviewed":true,"notes":""}]
isReviewedAll: true
notesAll: 

在 Controller 中运行以下代码后

Gson gson = new Gson();
gson.toJson(request.getParameter("selectedDtlId"));

回应

"[{\"id\":\"3\",\"isReviewed\":true,\"notes\":\"notes asdf test add 2\"},{\"id\":\"2\",\"isReviewed\":true,\"notes\":\"\"},{\"id\":\"1\",\"isReviewed\":true,\"notes\":\"\"}]"

预期 react

[
   {
      "id": "3",
      "isReviewed": true,
      "notes": "notes asdf test add 2"
   },
   {
      "id": "2",
      "isReviewed": true,
      "notes": ""
   },
   {
      "id": "1",
      "isReviewed": true,
      "notes": ""
   }
]

当你应该调用 fromJson 时，你却调用了 toJson:

gson.fromJson(request.getParameter("selectedDtlId"), JsonElement.class);

或者如果您有模型:

gson.fromJson(request.getParameter("selectedDtlId"), MyModel.class);
