mongodb you can't add a second

问题信息：

Due to limitations of the com.mongodb.BasicDBObject, you can't add a second 'createTime' expression specified as 'createTime : { "$lt" : 1468339200000}'. Criteria already contains 'createTime : { "$gt" : 1468252800000}'.

------------------------之前代码----------------------------------------

if(endTime!=null){

    endTime = DateUtil.getEndOfDay(endTime);

}

if (startTime !=null) {

    criteria.and("createTime").gte(startTime);

}

if(endTime!=null){

    criteria.and("createTime").lte(endTime);

}

------------------------修改代码----------------------------------------

if(endTime!=null){

    endTime = DateUtil.getEndOfDay(endTime);

}

if (startTime !=null&&endTime==null) {

    criteria.and("createTime").gte(startTime);

}else if(startTime==null&&endTime!=null){

    criteria.and("createTime").lte(endTime);

}else if(startTime!=null&&endTime!=null){

    criteria.andOperator(

            Criteria.where("createTime").gte(startTime),

            Criteria.where("createTime").lte(endTime)

    );
}
