Der Kern-JS-Code lautet wie folgt:

table.render({
   elem: &#39;#test-table-toolbar&#39;
 ,url:"http://localhost:8090/program-web/api/magic_change/oj/problem/page_list?userId=youcongtech"
   ,toolbar: &#39;#test-table-toolbar-toolbarDemo&#39;
   ,title: &#39;程序设计题绑定&#39;
,cols: [[
  {type: &#39;checkbox&#39;, fixed: &#39;left&#39;},
     {field:&#39;problemId&#39;, width:300, title: &#39;ID&#39;, sort: true}
     ,{field:&#39;title&#39;, width:400, title: &#39;题目&#39;}
     ,{width:215, align:&#39;center&#39;, fixed: &#39;right&#39;, toolbar: &#39;#test-table-toolbar-barDemo&#39;}
   ]]
   ,page: true
 });

Das erforderliche Hintergrund-Rückgabedatenformat muss sein:

{
  "msg": "success",
  "code": "0",
  "data": [
    {
      "title": "for循环输出",
      "problemId": 1139
    },
    {
      "title": "测试2",
      "problemId": 1138
    },
    {
      "title": "测试1",
      "problemId": 1137
    },
    {
      "title": "for循环-Plus",
      "problemId": 1140
    },
    {
      "title": "第一个C++程序",
      "problemId": 1141
    }
  ]
}

Andernfalls werden relevante Eingabeaufforderungen angezeigt (z. B. muss der Wert des Codes 0 und nicht 000000 sein, und die entsprechenden Daten müssen andernfalls wie oben sein). Es wird nicht automatisch in Spalten abgebildet.

Der Hintergrundimplementierungscode lautet wie folgt:

Steuerschichtcode (Routing)

@GetMapping("/page_list")
@ApiOperation(value="根据用户ID获取题目分页列表",httpMethod="GET",notes="根据用户ID获取题目分页列表")
public JSONObject page_list(@RequestParam String userId, @RequestParam (value="page") String pageno, @RequestParam (value="limit") String pagesize) {
    
    System.out.println("userId:"+userId+"|| pageno:"+pageno+"||pagesize:"+pagesize);
    
    JSONObject json = new JSONObject();
    
    //当前页
    Integer page = Integer.parseInt(pageno.trim());
    //每页的数量
    Integer size = Integer.parseInt(pagesize.trim());

    Map<String, Object> paramMap = new HashMap<>();
    paramMap.put("userId", userId);
    paramMap.put("start", (page - 1) * size);  //当前页的数量
    paramMap.put("size", size);  //当前页
    
    List<Problem> problemList = problemService.getProblemPageListInfo(paramMap);
     
    int count =problemService.getProblemPageTotalCount(paramMap);

    if(!problemList.isEmpty()) {

        json.put("msg", "success");
        json.put("code", "0");
        json.put("data", problemList);
        json.put("count", count);
        
    }else {
        
        json.put(CommonEnum.RETURN_MSG, "error");
        json.put(CommonEnum.RETURN_CODE, "222222");
    }
    
    return json;

}

Dienst und seine Implementierungsklasse:

Dienstimplementierungsklasse:
