java中redis增删查以及清理缓存的案例

我就废话不多说了，大家还是直接看代码吧~

@ApiOperation(value = '获取信息放入Redis中') @RequestMapping(value = '/getPropertyTakeLookShoppingDetailRedis',method = RequestMethod.POST) public JsonResult getPropertyTakeLookShoppingDetailRedis(@RequestBody PropertyTakeLookRedisParam param) throws Exception { log.info('PropertyTakeLookController.getPropertyTakeLookShoppingDetailRedis:' + param); JSONObject jsonObject = propertyTakeLookWriteService.getPropertyTakeLookShoppingDetailRedis(param); log.info('PropertyTakeLookController.getPropertyTakeLookSysInfo:' + jsonObject); return JsonResult.getResult(jsonObject); }Service

增删查区分 读缓存 = 0; 添加 =1;删除 = 2 ; 清除相应经纪人清单缓存 = 3 ')

/** * 获取信息放入Redis中 * @return * @throws Exception */ public JSONObject getPropertyTakeLookShoppingDetailRedis(PropertyTakeLookRedisParam param) throws Exception { String takeLookStr = 'DKQD'; checkArgument(StringUtils.isNotBlank(param.getTakeLookUserEmpNo()), '工号不能为空！'); checkArgument(param.getSelOrAddOrRemove() != null, '增删查区分不能为空！'); String takeLookUserEmpNo = param.getTakeLookUserEmpNo(); JSONObject jsonObject; if(redisHandle.exists(takeLookUserEmpNo+takeLookStr) && param.getSelOrAddOrRemove() == 0){ jsonObject = JSONObject.parseObject(redisHandle.get(takeLookUserEmpNo+takeLookStr).toString()); } else if(param.getSelOrAddOrRemove() == 1 || param.getSelOrAddOrRemove() == 2){ Long[] effectiveIds = param.getPropertyEffectiveId(); PropertyTakeLookShoppingCartParam propertyTakeLookShoppingCartParam = new PropertyTakeLookShoppingCartParam(); BeanUtils.copyProperties(param,propertyTakeLookShoppingCartParam); propertyTakeLookShoppingCartParam.setPropertyEffectiveId(effectiveIds); //获取信息 PageInfo<?> takeLookDetail = propertytakelookService.getPropertyTakeLookShoppingCartDetail(propertyTakeLookShoppingCartParam); System.out.print('参数查看' + JsonResult.getResult(takeLookDetail).toJson()); jsonObject = JSONObject.parseObject(JsonResult.getResult(takeLookDetail).toJson()); Object jsonArray = jsonObject.get('data'); redisHandle.set(takeLookUserEmpNo+takeLookStr,jsonArray); }else if (redisHandle.exists(takeLookUserEmpNo+takeLookStr) && param.getSelOrAddOrRemove() == 3){ //物理清除缓存 redisHandle.remove(takeLookUserEmpNo+takeLookStr); jsonObject = new JSONObject(); jsonObject.put('code',ErrorCode.SUCCESS.getCode()); jsonObject.put('msg',ErrorCode.SUCCESS.getMsg()); }else { jsonObject = new JSONObject(); jsonObject.put('code',ErrorCode.SUCCESS.getCode()); jsonObject.put('msg',ErrorCode.SUCCESS.getMsg()); } return jsonObject; }

补充：java按照关键字指定的key删除redis(支持模糊删除)

<dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.5.0</version> </dependency>代码直接可用：

import org.testng.annotations.BeforeClass;import org.testng.annotations.Test;import redis.clients.jedis.Jedis;import java.util.HashMap;import java.util.Iterator;import java.util.List;import java.util.Map;public class TestRedis { private Jedis jedis; @BeforeClass public void setup() { //连接redis服务器，ip jedis = new Jedis('ip', 6379); //权限认证 jedis.auth('123456'); } /** * 删除数据 * * * @param key：要删除数据的key * @return：返回boolean值，表示是否删除成功 */ public boolean delete(String key) { if (jedis.exists(key)) { if (jedis.del(key) == 1) { System.out.println('删除数据成功'); return true; } else { System.out.println('删除数据失败'); return false; } } else { System.out.println(key + '不存在'); return false; } } @Test public void test() { delete('age'); }}

以上为个人经验，希望能给大家一个参考，也希望大家多多支持好吧啦网。如有错误或未考虑完全的地方，望不吝赐教。
