这是前端的数据结构 

  data() {
            return {
                loading: false,
                inputForm: {
                    id: '${gridProject.id}',
                    gridName: '',
                    gridId: '',
                    projectName: '',
                    projectId: '',
                    type: ''
                },
                data: [],
                value: []
            }

        },

        其中 gridId 和 type 是单个参数 , value 是个数组，注意 这里data中的value[]不要直接给后端传过去，需要转接下再发送过去

// 提交
doSubmit(call) {
                let value = this.value
                let type = this.inputForm.type
                this.post('${ctx}/basicinfo/gridProject/save?gridId=' + this.inputForm.gridId + '&type=' + type, value).then((res) => {
                    if (res.success) {
                        this.$message.success(res.msg)
                        call()
                    } else {
                        this.$message.error(res.msg)
                    }
                })
}

        后端做接受时需要添加 @RequestBody 和 @RequestParam注解区分前端传来的数据

    /**
     * 保存网格项目关联信息
     *
     */
    @ApiOperation("保存")
    @ResponseBody
    @PostMapping(value = "save")
    public AjaxJson save(@RequestBody @RequestParam("gridId") String gridId,@RequestBody String[] value,@RequestBody @RequestParam("type") String type) throws Exception {
        gridProjectService.saveProject(gridId,value,type);
        return AjaxJson.success("保存网格项目关联信息成功");
    }
