java.lang.IllegalStateException:Type handler was null on parameter mapping for property ‘__frch_listItem_2’. It was either not specified and/or could not be found for the javaType ([J) : jdbcType (null) combination.
今天数据库报这个错误,后来发现是因为参数类型写错了
应该是这样,而我却写成小写了 long
@PutMapping("/pull/many") public Result pullMany(@RequestBody Long[] ids) { int count = spuService.pullMany(ids); return new Result(true,StatusCode.OK,"下架架"+count+"个商品"); }
错误示范:
