1、单机配置
@Component@ConfigurationProperties(prefix = "spring.redis")public class RedisConfigProperties { private String password; private String database; private int port; private String host; /** * @return the password */ public String getPassword() { return password; } /** * @param password the password to set */ public void setPassword(String password) { this.password = password; } /** * @return the database */ public String getDatabase() { return database; } /** * @param database the database to set */ public void setDatabase(String database) { this.database = database; } /** * @return the port */ public int getPort() { return port; } /** * @param port the port to set */ public void setPort(int port) { this.port = port; } /** * @return the host */ public String getHost() { return host; } /** * @param host the host to set */ public void setHost(String host) { this.host = host; } }
@Configurationpublic class RedissonConfig { @Autowired private RedisConfigProperties redisConfigProperties; //添加redisson的bean @Bean public Redisson redisson() { //redisson版本是3.5,集群的ip前面要加上“redis://”,不然会报错,3.2版本可不加 String redissonAddr = "redis://" + redisConfigProperties.getHost()+":"+redisConfigProperties.getPort(); Config config = new Config(); SingleServerConfig singleConfig = config.useSingleServer().setAddress(redissonAddr). //心跳检测,定时与redis连接,可以防止一段时间过后,与redis的连接断开 setPingConnectionInterval(1000); singleConfig.setPassword(redisConfigProperties.getPassword());//设置密码 return (Redisson) Redisson.create(config); } }
2、集群配置
@Component@ConfigurationProperties(prefix = "spring.redis")public class RedisConfigProperties { private String password; private cluster cluster; public static class cluster { private List<String> nodes; public List<String> getNodes() { return nodes; } public void setNodes(List<String> nodes) { this.nodes = nodes; } } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public RedisConfigProperties.cluster getCluster() { return cluster; } public void setCluster(RedisConfigProperties.cluster cluster) { this.cluster = cluster; } }
@Configurationpublic class RedissonConfig { @Autowired private RedisConfigProperties redisConfigProperties; //添加redisson的bean @Bean public Redisson redisson() { //redisson版本是3.5,集群的ip前面要加上“redis://”,不然会报错,3.2版本可不加 List<String> clusterNodes = new ArrayList<>(); for (int i = 0; i < redisConfigProperties.getCluster().getNodes().size(); i++) { clusterNodes.add("redis://" + redisConfigProperties.getCluster().getNodes().get(i)); } Config config = new Config(); ClusterServersConfig clusterServersConfig = config.useClusterServers() .addNodeAddress(clusterNodes.toArray(new String[clusterNodes.size()])); //心跳检测,定时与redis连接,可以防止一段时间过后,与redis的连接断开 clusterServersConfig.setPingConnectionInterval(1000); clusterServersConfig.setPassword(redisConfigProperties.getPassword());//设置密码 return (Redisson) Redisson.create(config); } }
3、使用方法
public boolean test1() throws Exception { String LOCK_STATUS = "lock_status"; RLock lock = null; try { lock = redissonClient.getLock(LOCK_STATUS); if (lock.tryLock()) { //业务..... } else { return false; } } catch (Exception e) { logger.error("err",e); }finally { if(null != lock && lock.isHeldByCurrentThread()) { lock.unlock(); } } return true; }
