前端传JSON对象到后端转到List集合

前端代码：

依赖JQ

$.ajax({
    url: url,
    type: "post",
    async: false,
    data: JSON.stringify(json),  //主要是这里传参方式，需要把JSON对象转成JSON字符串
    dataType : "json",
    contentType : 'application/json;charset=utf-8',
    success:function(data){
        
    },
    error : function(xhr,textStatus) {
        
    }
});

JAVA 后端Controller接收代码：

@RequestMapping(value = "/saveTest", method = RequestMethod.POST)
@ResponseBody
public void saveTest(
        HttpServletResponse response,
        HttpServletRequest request,
        @RequestBody List<CheckDetail> checkDetailList //主要是这里接收参数
)  {

    log.info(checkDetailList.toString());

}
