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;
}
}
@Configuration
public 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;
}
}
@Configuration
public 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;
}
