redis存取list集合

一 、存取为list类型

1. @RestController

2. @RequestMapping("/test")

3. @Slf4j

4. publicclassTestController

5. @Autowired

6. private RedisTemplate redisTemplate;

7. @ApiOperation("redis-savelist")

8. @PostMapping("/redis/save/list")

9. public void redisSaveList() {

10. Listlist = getPersonList();

11. //清空

12. while (redisTemplate.opsForList().size("oowwoo") >0){

13. redisTemplate.opsForList().leftPop("oowwoo");

14. }

15. //存储

16. redisTemplate.opsForList().rightPushAll("oowwoo",list);

17. //取出

18. List oowwoo = redisTemplate.opsForList().range("oowwoo",0,-1);

19. log.info(">>>>>>>>>>>>>>>list = {}", oowwoo.toString());

20. Iterator it = oowwoo.iterator();

21. while(it.hasNext()){

22. Person p = it.next();

23. log.info("person = {}", p.toString());

24. }

25. }

26. privateList getPersonList() {

27. Person p1 =new Person();

28. p1.setId(1L);

29. p1.setName("张一");

30. p1.setAge(11);

31. Person p2 =new Person();

32. p2.setId(2L);

33. p2.setName("张二");

34. p2.setAge(22);

35. Person p3 =new Person();

36. p3.setId(3L);

37. p3.setName("张三");

38. p3.setAge(33);

39. Listlist =new ArrayList<>();

40. list.add(p1);

41. list.add(p2);

42. list.add(p3);

43. returnlist;

44. }

45. }

二 、将list转为json对象存取

1. import com.alibaba.fastjson.JSON;

2. import com.alibaba.fastjson.JSONObject;

3. @Autowired

4. private StringRedisTemplate stringRedisTemplate;

5. //存

6. List businessIdList = eeFreecarriageShopService.selectBusinessIdInPromotion();

7. stringRedisTemplate.opsForValue().set(RedisConstants.FREECARRIAGE_BUSINESSIDLIST, JSON.toJSON(businessIdList).toString());

8. //取

9. String businessJsonArray = stringRedisTemplate.opsForValue().get(RedisConstants.FREECARRIAGE_BUSINESSIDLIST);

10. List businessIdList = JSONObject.parseArray(businessJsonArray,Long.class);
