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~

Controller

@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)

pom依赖：

 <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。如有错误或未考虑完全的地方，望不吝赐教。

离开之后，我想你不要忘记一件事：不要忘记想念我。
