安装redis忽略,对redis加密码,增加安全性 在redis.config 里面添加requirepass passWord(密码内容) 然后绑定本机ip (bind 127.0.0.1)如下 (未实验)
修改 redis.conf 文件,添加密码
requirepass passWord(密码内容)
修改 redis.conf 文件,绑定本机ip(指定哪个ip能够访问)
bind 127.0.0.1
配置redis
spring项目下,需要导入commons-pool-1.5.6.jar、commons-pool2-2.4.2.jar、jedis-2.7.3.jar、spring-data-redis-1.6.0.RELEASE.jar文件。在spring配置文件中加入以下元素:
<bean id="redisUtil" class="com.project.controller.Redis.RedisUtil"> <!-- 初始化类 --> <property name="addr"><value>127.0.0.1</value></property> <!-- 访问地址,默认本地 --> <property name="port"><value>6379</value></property> <!-- 端口号 --> <property name="auth"><value>master</value></property> <property name="maxIdle"><value>200</value></property> <property name="maxActive"><value>1024</value></property> <property name="maxWait"><value>10000</value></property> <property name="timeOut"><value>10000</value></property> <property name="testOnBorrow"><value>true</value></property> </bean>
RedisUtil代码:
public class RedisUtil implements Serializable{ private static final long serialVersionUID = -1149678082569464779L; //Redis服务器IP private static String addr; //Redis的端口号 private static int port; //访问密码 private static String auth; //可用连接实例的最大数目,默认值为8; //如果赋值为-1,则表示不限制;如果pool已经分配了maxActive个jedis实例,则此时pool的状态为exhausted(耗尽)。 private static int maxActive; //控制一个pool最多有多少个状态为idle(空闲的)的jedis实例,默认值也是8。 private static int maxIdle; //等待可用连接的最大时间,单位毫秒,默认值为-1,表示永不超时。如果超过等待时间,则直接抛出JedisConnectionException; private static int maxWait; private static int timeOut; //在borrow一个jedis实例时,是否提前进行validate操作;如果为true,则得到的jedis实例均是可用的; private static boolean testOnBorrow; public static Jedis jedis;//非切片额客户端连接 public static JedisPool jedisPool;//非切片连接池 public static ShardedJedis shardedJedis;//切片额客户端连接 public static ShardedJedisPool shardedJedisPool;//切片连接池 private static void initialPool() { // 池基本配置 JedisPoolConfig config = new JedisPoolConfig(); config.setMaxTotal(maxActive); config.setMaxIdle(maxIdle); config.setMaxWaitMillis(maxWait); config.setTestOnBorrow(testOnBorrow); jedisPool = new JedisPool(config, addr, port); } private static void initialShardedPool() { // 池基本配置 JedisPoolConfig config = new JedisPoolConfig(); config.setMaxTotal(maxActive); config.setMaxIdle(maxIdle); config.setMaxWaitMillis(maxWait); config.setTestOnBorrow(testOnBorrow); // slave链接 List<JedisShardInfo> shards = new ArrayList<JedisShardInfo>(); shards.add(new JedisShardInfo(addr, port, auth)); // 构造池 shardedJedisPool = new ShardedJedisPool(config, shards); } public static void afterPropertiesSet() throws Exception { // TODO Auto-generated method stub initialPool(); initialShardedPool(); try { shardedJedis = shardedJedisPool.getResource(); } catch (Exception e) { System.out.println("连接shardedJedisPool失败!"); } try { jedis = jedisPool.getResource(); } catch (Exception e) { System.out.println("连接jedisPool失败!"); } } public String getAddr() { return addr; } public void setAddr(String addr) { this.addr = addr; } public int getPort() { return port; } public void setPort(int port) { this.port = port; } public String getAuth() { return auth; } public void setAuth(String auth) { this.auth = auth; } public int getMaxActive() { return maxActive; } public void setMaxActive(int maxActive) { this.maxActive = maxActive; } public int getMaxIdle() { return maxIdle; } public void setMaxIdle(int maxIdle) { this.maxIdle = maxIdle; } public int getMaxWait() { return maxWait; } public void setMaxWait(int maxWait) { this.maxWait = maxWait; } public int getTimeOut() { return timeOut; } public void setTimeOut(int timeOut) { this.timeOut = timeOut; } public boolean isTestOnBorrow() { return testOnBorrow; } public void setTestOnBorrow(boolean testOnBorrow) { this.testOnBorrow = testOnBorrow; } }
测试功能
//redis-server.exe启动状态下 public void selectReviewsByGoodsId(HttpServletRequest request){ try { Jedis jedis = new Jedis(); Date time1 = new Date(); jedis.set("goodsName","IphoneX"); Date time2 = new Date(); System.out.println("消耗时间:"+(time2.getTime()-time1.getTime())); System.out.println("商品列表存入redis完毕"); System.out.println(jedis.get("goodsName")); } catch (Exception e) { //如果缓存连不上,则不处理 System.out.println("登录无法更新该用户缓存"); } }
