有点晚的答案，但也许这会对将来的某人有所帮助：
在数据表设置中，我们需要告诉 jQuery不处理数据并发送 JSON：
ajax: {
url: "/some/url.json"),
type: "POST",
data: function (data) {
return JSON.stringify(data);
},
dataType: "json",
processData: false,
contentType: 'application/json;charset=UTF-8'
},
在 Spring 方面：
@RequestMapping(value = "/some/url")
@ResponseBody
public DataTablesResponse<Element> list(@RequestBody final DataTablesRequest dataTablesRequest) {
// query the DB to get the number of elements (without filtering)
// and the list of elements (filtered and/or paginated)
return new DataTablesResponse(numberOfElements, notifications.getTotalElements(), dataTablesRequest.getDraw(), "", listOfElements);
}
DataTablesRequest 等的以下内容（@Data 来自 lombok，javadoc cmets 来自官方数据表文档。）：
@Data
public class DataTablesRequest {
/**
* Draw counter. This is used by DataTables to ensure that the Ajax returns from server-side processing requests are drawn in sequence by DataTables
* (Ajax requests are asynchronous and thus can return out of sequence). This is used as part of the draw return parameter (see below).
