This time I will show you how to use postman json springmvc to implement the batch addition function, and what are the precautions for using postman json springmvc to implement the batch addition function. The following is a practical case, let's take a look.
postman tool configuration and data preparation:
1) Enter the test IP address and the interface address corresponding to the port number in the address bar;2) Add the parameter Content-Type=application/json in the Headers column;has been tested locally as an example: the corresponding configuration diagram is as follows:
data set to be transferred and added in the corresponding text areacombination;
This example has two pieces of data, as shown below:
The object corresponds to a database record to be saved by the backend interface, a java object;
At this point, the configuration of postMan is completed. Just click the send button to trigger the send event to send the data in json format to the backend. interface.Server interface configuration: springmvc has been used to illustrate:
Annotations on the controller class object are the same as other ordinary controller objects;@RestController @RequestMapping("/room-call") public class RoomCallController { /** * 同时添加多条即时建议接口,参数接收要测试。 * * @param roomCallModels 要存储的即时建议集合 * @return 存储成功 */ @RequestMapping(value = "/add-all", method = RequestMethod.POST) public JSONResult addAllRoomCall(@RequestBody List<RoomCallModel> roomCallModels) { //对接收参数做空判断,防止空指针 if (CollectionUtils.isEmpty(roomCallModels)) { return CommonError.PARAM_IS_NULL.toJSONResult("即使建议数据"); } for (RoomCallModel roomCallModel : roomCallModels ) { //操作接受到的对象集合,依次入库,完成指定业务; } }
