详细异常信息如下：

          }
        }
      }
    ]
  },
  "status": 400

从caused_by找出导致异常的根本原因，For input string:\"|""。因为查询参数中传入了数组，再查看项目中构建DSL语句，终于找到异常爆发的原因了，

 if(!CollectionUtils.isEmpty(params.getBrandId())){
      boolQuery.filter(QueryBuilders.termQuery("brandId",params.getBrandId()));
  }

而参数brandId是List类型，允许传入多个值，因此使用termQuery是错误的，它只能传入一个值，很明显是这里调错方法了,多个值的集合、数组，应该使用termsQuery方法，把方法调整过来就不报错了。附2个方法的传参对比：
