}
4.CacheConfiguration
@Configuration
@EnableConfigurationProperties(RedisProperties.class)
public class CacheConfiguration {
@Autowired
RedisProperties redisProperties;
@Configuration
@ConditionalOnClass({Redisson.class})
@ConditionalOnExpression("'${spring.redis.mode}'=='single' or '${spring.redis.mode}'=='cluster' or '${spring.redis.mode}'=='sentinel'")
protected class RedissonSingleClientConfiguration {
/**
* 单机模式 redisson 客户端
*/
@Bean
@ConditionalOnProperty(name = "spring.redis.mode", havingValue = "single")
RedissonClient redissonSingle() {
Config config = new Config();
String node = redisProperties.getSingle().getAddress();
node = node.startsWith("redis://") ? node : "redis://" + node;
SingleServerConfig serverConfig = config.useSingleServer()
.setAddress(node)
.setTimeout(redisProperties.getPool().getConnTimeout())
.setConnectionPoolSize(redisProperties.getPool().getSize())
.setConnectionMinimumIdleSize(redisProperties.getPool().getMinIdle());
if (StringUtils.isNotBlank(redisProperties.getPassword())) {
serverConfig.setPassword(redisProperties.getPassword());
}
return Redisson.create(config);
}
/**
* 集群模式的 redisson 客户端
*
* @return
*/
@Bean
@ConditionalOnProperty(name = "spring.redis.mode", havingValue = "cluster")
RedissonClient redissonCluster() {
System.out.println("cluster redisProperties:" + redisProperties.getCluster());
Config config = new Config();
String[] nodes = redisProperties.getCluster().getNodes().split(",");
List newNodes = new ArrayList(nodes.length);
Arrays.stream(nodes).forEach((index) -> newNodes.add(
index.startsWith("redis://") ? index : "redis://" + index));
ClusterServersConfig serverConfig = config.useClusterServers()
.addNodeAddress(newNodes.toArray(new String[0]))
.setScanInterval(
redisProperties.getCluster().getScanInterval())
.setIdleConnectionTimeout(
redisProperties.getPool().getSoTimeout())
.setConnectTimeout(
redisProperties.getPool().getConnTimeout())
.setFailedAttempts(
redisProperties.getCluster().getFailedAttempts())
.setRetryAttempts(
redisProperties.getCluster().getRetryAttempts())
.setRetryInterval(
redisProperties.getCluster().getRetryInterval())
.setMasterConnectionPoolSize(redisProperties.getCluster()
.getMasterConnectionPoolSize())
.setSlaveConnectionPoolSize(redisProperties.getCluster()
.getSlaveConnectionPoolSize())
.setTimeout(redisProperties.getTimeout());
if (StringUtils.isNotBlank(redisProperties.getPassword())) {
serverConfig.setPassword(redisProperties.getPassword());
}
return Redisson.create(config);
}
/**
* 哨兵模式 redisson 客户端
* @return
*/
@Bean
@ConditionalOnProperty(name = "spring.redis.mode", havingValue = "sentinel")
RedissonClient redissonSentinel() {
System.out.println("sentinel redisProperties:" + redisProperties.getSentinel());
Config config = new Config();
String[] nodes = redisProperties.getSentinel().getNodes().split(",");
List newNodes = new ArrayList(nodes.length);
Arrays.stream(nodes).forEach((index) -> newNodes.add(
index.startsWith("redis://") ? index : "redis://" + index));
SentinelServersConfig serverConfig = config.useSentinelServers()
.addSentinelAddress(newNodes.toArray(new String[0]))
.setMasterName(redisProperties.getSentinel().getMaster())
.setReadMode(ReadMode.SLAVE)
.setFailedAttempts(redisProperties.getSentinel().getFailMax())
.setTimeout(redisProperties.getTimeout())
.setMasterConnectionPoolSize(redisProperties.getPool().getSize())
.setSlaveConnectionPoolSize(redisProperties.getPool().getSize());
if (StringUtils.isNotBlank(redisProperties.getPassword())) {
serverConfig.setPassword(redisProperties.getPassword());
}
return Redisson.create(config);
}
}
}
5.使用时候直接注入RedissClient客户端就可以使用
如下这样写的目的是为了统一给其它服务提供接口
@Autowired
RedissonClient redisson;
@RequestMapping(value = "lock", method = RequestMethod.POST, consumes = "application/json;charset=UTF-8", produces = "application/json;charset=UTF-8")
public @ResponseBody
ServerResponse lock(@RequestBody ServerRequest req) {
return callR(redisson -> {
RLock lock = redisson.getLock(req.getReqBody().getLockKey());
lock.lock(req.getReqBody().getTimeout(), req.getReqBody().getUnit());
return lock;
});
}
//省略部分代码
private ServerResponse callR(Function function) {
ServerResponse dv = RespHelper.serverResponse(RespCodeService.ERROR, "");
try {
long startTime = System.currentTimeMillis();
dv = RespHelper.serverResponse(RespCodeService.SUCCESS, function.apply(redisson));
logger.info("CALLR METHOD USE TIME:{}", System.currentTimeMillis() - startTime);
} catch (Throwable e) {
System.out.println("callR error");
}
return dv;
}
