springmvc 接收数组 list对象参数

今天遇到一个数组类型的对象，传递到后台的问题，各种查阅资料，再此做个记录，遇到同样问题的同学也可以作个参考。

后台springmvc 接口：

@RequestMapping("/saveFileBusiness")
    	@ResponseBody
    	public HttpJsonResponse saveFileBusiness(FileBusinessList fbs) {
    		try {
    			List<FileBusiness> list = fbs.getFbs();
    			if(ListUtil.isNotBlank(list)) {
    				for(FileBusiness fb:list) {
    					fb.setFbadduserid(getCurtAccount().getId());
    				}
    				fileBusinessService.batchAdd(list);
    			}
    			return getResponseSuc(null);
    		}catch (Exception e) {
    			LogUtil.PrintErrorMsg(e, log);
    			return getResponseErr(e);
    		}
    		
    	}

后台封装了个list<对象>类FileBusinessList

public class FileBusinessList {
    
    	private List<FileBusiness> fbs;
    
    	public List<FileBusiness> getFbs() {
    		return fbs;
    	}
    
    	public void setFbs(List<FileBusiness> fbs) {
    		this.fbs = fbs;
    	}
    }

前台ajax核心部分

var data =new Object();
    for(var i=0;i<Obj.length;i++){
    	data["fbs["+i+"].fbfileid"]=Obj[i].fileId;
    	data["fbs["+i+"].fbtype"]=Obj[i].fileType;
    	data["fbs["+i+"].fbconverttype"]=Obj[i].conerType;
    	data["fbs["+i+"].fbpages"]=Obj[i].pages;
    	data["fbs["+i+"].fbdesc"]="文件说明";
    	data["fbs["+i+"].fbpatientid"]="1";
    	data["fbs["+i+"].fbillnessid"]="1";
    	data["fbs["+i+"].fbillnesscheckid"]="1";
    };
    //data,作为ajax的data参数
    sendAjax(data);

postman测试

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xvdmVib3NvbQ_size_16_color_FFFFFF_t_70][]

上图是key-value模式，下图是Buik Edit模式：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xvdmVib3NvbQ_size_16_color_FFFFFF_t_70 1][]

这样后台就能接收到数据了 ，
