私人vps网站的redis做多字段排序的示例：



在redis编辑器中添加以下代码：



packagecom.example.demo;



importcom.example.demo.common.Constant;



importcom.example.demo.mapper.QuestionAnswerHistoryMapper;



importcom.example.demo.model.QuestionAnswerHistory;



importcom.example.demo.service.QuestionAnswerHistoryService;



importcom.example.demo.thread.BaseTest;



importorg.apache.commons.lang3.RandomUtils;



importorg.junit.Test;



importorg.springframework.beans.factory.annotation.Autowired;



importjava.math.BigDecimal;



importjava.util.List;



/**

*/



publicclassQuestionAnswerHistoryTestextendsBaseTest{



@Autowired



privateQuestionAnswerHistoryMapperhistoryMapper;



@Autowired



privateQuestionAnswerHistoryServicehistoryService;



@Test



publicvoidtest(){



for(inti=1;i<101;i++){



QuestionAnswerHistoryhistory=newQuestionAnswerHistory();



history.setUserId((long)i);



history.setAnswerFinish(true);



BigDecimalbigDecimal=BigDecimal.valueOf(RandomUtils.nextDouble(0,1))



.setScale(2,BigDecimal.ROUND_HALF_UP);



history.setCorrectRate(bigDecimal.doubleValue());



history.setTimeConsumed(RandomUtils.nextInt(15,50));



history.setTimeConsumedMillisecond(RandomUtils.nextInt(0,1000));



history.setStatus(Constant.GenerictStatus.NORMAL);



historyMapper.insert(history);



}



}



@Test



publicvoidqueryRanking(){



Listranking=historyService.getRanking();



for(QuestionAnswerHistoryhistory:ranking){



System.out.println(history.getUserId()+"\t"+history.getCorrectRate()+"\t"+history.getTimeConsumed()+



"\t"+history.getTimeConsumedMillisecond());



}



}



@Test



publicvoidupdateRank(){



LonguserId=25L;



//生成新的答题记录



QuestionAnswerHistoryhistory=newQuestionAnswerHistory();



history.setUserId(userId);



history.setAnswerFinish(true);



BigDecimalbigDecimal=BigDecimal.valueOf(RandomUtils.nextDouble(0,1))



.setScale(2,BigDecimal.ROUND_HALF_UP);



history.setCorrectRate(bigDecimal.doubleValue());



history.setTimeConsumed(RandomUtils.nextInt(15,50));



history.setTimeConsumedMillisecond(RandomUtils.nextInt(0,1000));



history.setStatus(Constant.GenerictStatus.NORMAL);



historyService.updateRank(history);



}



}



输入结果：
