前端像后台传入数组，后台使用list接收的方法

前端AJAX:

        $.ajax({

          url:'http://192.168.1.112:8181/runtime/uav/bookmark/point/insert',

          type: 'post',

          async: false,

          data: JSON.stringify(linePoints),

          contentType: 'application/json;charset=utf-8',

          dataType: 'json',

          success(res) {

            debugger

            console.log(res)

          }

        }) 

 

注意：1.contentType必须为 'application/json;charset=utf-8',默认（会报415）   2.dataType: 'json',  3.data要序列化

 

后端：参数栏使用@RequestBody注解

public Integer insertLinePoint(@RequestBody List<LinePoint> linePoints) {
    Integer addCount = 0;
    return addCount;
}
