RedissonConfig
@Configuration
public class RedissonConfig {
@Value("${spring.redis.host}")
public String host;
@Value("${spring.redis.port}")
public String port;
@Bean
public RedissonClient redissonClient() {
Config config = new Config();
config.useSingleServer().setAddress("redis://" + host + ":" + port);
return Redisson.create(config);
}
}
使用
@Autowired
private RedissonClient redissonClient;
public void test(String phone) {
String key = "redis:phone:" + phone;
RLock rLock = redissonClient.getLock(key);
try {
boolean result = rLock.tryLock(3, 10, TimeUnit.SECONDS);
if (!result) {
System.out.println("获取分布式锁失败1");
} else {
System.out.println("获取分布式锁成功");
}
} catch (Exception e) {
System.out.println("获取分布式锁失败2");
} finally {
if(rLock.isLocked()) {
if(rLock.isHeldByCurrentThread()) {
rLock.unlock();
}
}
}
}
