前端ajax传参发请求：
$.ajax({
url:'/tjcx/qyzxcx/cwzb/gjcwzb',
type:'post',
data:{
'djxh':djxh,
'nds':app.lastYears
},
success:function (res) {
let data = res.data;
if (data.code === 200) {
app.tableData6 = data.data;
}
}
})
发出的数组叫nds
接收：
@ApiOperation("查询财务报表数据")
@PostMapping("/gjcwzb")
public ApiResponse getDataByDjxh(@RequestParam("djxh") @ApiParam(name = "djxh", value = "登记序号", required = true) String djxh,
@RequestParam("nds[]") @ApiParam(name = "nds[]", value = "最近三年数组", required = true) String[] nds) {
logger.info("请求->查询财务报表数据->输入参数【djxh:" + djxh + ",nds:" + nds + "】");
接收的时候，@RequestParam不能用nds接收，要用nds[]接收
