前端传入list 后端接受

转载与

前端页面传来数组,后台用对象集合list接收数据的写法
//保存页面显示应用
$("#save").click(function(){
var data = [{"applicationtypeid":"65","applicationsystemid":"30"},{"applicationtypeid":"65","applicationsystemid":"31"}];
$.ajax({
url: "${ctx}/applicationuser/save",
type: "POST",
contentType : 'application/json;charset=utf-8', //设置请求头信息
dataType:"json",
data: JSON.stringify(data), //将Json对象序列化成Json字符串，JSON.stringify()原生态方法
success: function(result){
console.log("保存页面显示应用",result);
},
error: function(res){
layer.msg("操作失败!",{icon: 5,time:2000});
}
});
});

/**

• 保存页面显示应用
  */
  @RequestMapping("/save")
  @ResponseBody
  //@RequiresPermissions("applicationuser:save")
  public JSONObject saveApplicationUser(@RequestBody List applicationUserList){
  return applicationUserService.saveApplicationUser(applicationUserList);
  }

第二种写法
/**

• 保存页面显示应用
  */
  @RequestMapping("/save")
  @ResponseBody
  public JSONObject saveApplicationUser(@RequestBody String str ,HttpServletRequest request){
  List applicationUserList = JSONArray.parseArray(str, ApplicationUserEntity.class);
  return applicationUserService.saveApplicationUser(applicationUserList,request);
  }
