项目场景：

在ES的使用过程中，用到了时间范围的查询功能，出现时间解析错误的报错信息：“caused_by”:{“type”:“illegal_argument_exception”,“reason”:"failed to parse date field …

问题描述

查询query对象部分字段描述

    @ApiModelProperty(value = "开始时间")
    @JsonFormat(locale="zh", timezone="GMT+8", pattern="yyyy-MM-dd HH:mm:ss")
    private Date searchStartTime;

    @ApiModelProperty(value = "结束时间")
    @JsonFormat(locale="zh", timezone="GMT+8", pattern="yyyy-MM-dd HH:mm:ss")
    private Date searchEndTime;

查询时间范围错误java代码

        //时间范围
        if (query.getSearchStartTime()!=null  && query.getSearchEndTime()!=null){
            RangeQueryBuilder rangeQuery = QueryBuilders.rangeQuery("createTime");
            rangeQuery.from(query.getSearchStartTime());
            rangeQuery.to(query.getSearchEndTime());
            //因为filter比query快，也可以将rangeQuery放入sourceBuilder
            boolQueryBuilder.filter(rangeQuery);
        }

原因分析：

es和mysql不同，mysql传入date后经过解析可以直接作为参数进行sql拼写，但是es貌似不行，需要转为时间戳

解决方案：

将时间参数转为时间戳进行查询

        //时间范围
        if (query.getSearchStartTime()!=null  && query.getSearchEndTime()!=null){
            RangeQueryBuilder rangeQuery = QueryBuilders.rangeQuery("createTime");
            rangeQuery.from(query.getSearchStartTime().getTime());
            rangeQuery.to(query.getSearchEndTime().getTime());
            //因为filter比query快，也可以将rangeQuery放入sourceBuilder
            boolQueryBuilder.filter(rangeQuery);
        }
