Question

尝试将JavaScript对象传递给Spring MVC。我收到400错误的请求错误。尝试了所有不同的方法，但仍然没有运气。我已经附加了Controller，我在JS和Java中传递的对象以及响应。将不胜感激。当我将@RequestBody更改为@ModelAttribute时，我在控制器中接收到参数，但整数为零，数组为空。

控制器

    @RequestMapping(value="/getInstrumentsByTypeMakeModel" , method=RequestMethod.GET)
    public @ResponseBody List<Instrument> getInstrumentsByTypeMakeModel(@RequestBody SearchInstrument search) {
     // do Something and create searchResult;   
    return searchResult;
}

JavaScript

var searchInstrument = {

    operator: siteOperator,
    companyId:loggedInUserCompanyId ,
    isServiceProvider:isServiceProvider ,
    types:selectedType,
      makes:selectedMake,
      models:selectedModel,
      typeOthers:selectedTypeOther,
      makeOthers:selectedMakeOther,
      modelOthers:selectedModelOther

    };



     jQuery.ajax({
         url:server_name+ "/getInstrumentsByTypeMakeModel",
         type: "GET",
        dataType: "JSON",
        data:JSON.stringify(searchInstrument),   
         contentType: 'application/json; charset=utf-8',
         success: function(resultData) {
             console.log(resultData);
            },
             error: function(jqXHR, status) {
                 // error handler

            }
        });

SearchInstrument类

public class SearchInstrument  {
    public SearchInstrument(){

    }

        public SearchInstrument(int operator,int companyId, boolean isServiceProvider,
                List<Integer>  types,List<Integer>  makes,  List<Integer>  models,
                List<String>  typeOthers,List<String>  makeOthers,List<String>  modelOthers
                ){

this.operator=operator;
this.companyId=companyId;
this.types=types;
this.makes=makes;
this.models=models;
this.typeOthers=typeOthers;
this.makeOthers=makeOthers;
this.modelOthers=modelOthers;
        }
        private int operator;
        private int companyId;
        private boolean isServiceProvider;
        private List<Integer>  types=new ArrayList<Integer> ();
        private List<Integer>  makes=new ArrayList<Integer> ();
        private List<Integer>  models=new ArrayList<Integer> ();    
        private List<String>  typeOthers=new ArrayList<String> ();
        private List<String>  makeOthers=new ArrayList<String> ();
        private List<String>  modelOthers=new ArrayList<String> ();

//getters and setters       

    }

我不确定，但是结合GET请求并尝试传递一个对象并不是最好的主意，这就是为什么您在URL中看到searchController JS对象的原因第二张图片。

以下question有更详尽的解释。

我认为您应该尝试将其转换为POST请求。

或者，如果您出于某种原因仍希望将其保留为GET，则应在URL中将对象作为参数传递，并在控制器中使用@RequestParam。
