改造RedisConnectionFactory

/*** 根据缓存策略的不同，RedisConnectionFactory不同* 示例是单机模式。** @return*/
@Bean
public RedisConnectionFactory redisConnectionFactory() {while (true) {try {LOCK.tryLock(100, TimeUnit.MILLISECONDS);/*** 心跳返回的请求为空；*/String response = HttpUtils.doGet("http://localhost:5005/cache/client/redis/standalone/10000.json?clientVersion=1.0-SNAPSHOT");if (response == null || response.isEmpty()) {continue;}JSONObject jsonObject = null;try {jsonObject = JSONObject.parseObject(response);} catch (Exception e) {}if (jsonObject == null) {continue;}/*** 从心跳中提取HostAndPort，构造JedisPool实例；*/String instance = jsonObject.getString("standalone");String[] instanceArr = instance.split(":");if (instanceArr.length != 2) {continue;}//收集上报数据ClientDataCollectReportExecutor.getInstance("http://localhost:5005/cachecloud/client/reportData.json");String password = jsonObject.getString("password");String host = instanceArr[0];String port = instanceArr[1];JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory();jedisConnectionFactory.setPassword(password);jedisConnectionFactory.setHostName(host);jedisConnectionFactory.setPort(Integer.parseInt(port));return jedisConnectionFactory;} catch (InterruptedException e) {logger.error("error in build().", e);}}
}

改造 jedis-2.9.0

Connection.java

/*** 命令捕获，异常保存* @param cmd* @param args*/
public void sendCommand(final ProtocolCommand cmd, final byte[]... args) {try {//统计开始UsefulDataModel costModel = UsefulDataModel.getCostModel(threadLocal);costModel.setCommand(cmd.toString().toLowerCase());costModel.setStartTime(System.currentTimeMillis());connect();Protocol.sendCommand(outputStream, cmd, args);} catch (JedisConnectionException ex) {UsefulDataCollector.collectException(ex, getHostPort(), System.currentTimeMillis());broken = true;throw ex;}
}

JedisClusterCommand.java

private T runWithRetries(byte[] key, int attempts, boolean tryRandomNode, boolean asking) {if (attempts <= 0) {JedisClusterMaxRedirectionsException exception = new JedisClusterMaxRedirectionsException("Too many Cluster redirections? key=" + SafeEncoder.encode(key));//收集UsefulDataCollector.collectException(exception, "", System.currentTimeMillis(), ClientExceptionType.REDIS_CLUSTER);throw exception;}
}

更新spring-boot-starter-data-redis依赖

 <!--Redis-->
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId><exclusions><exclusion><artifactId>jedis</artifactId><groupId>redis.clients</groupId></exclusion></exclusions>

<!--上步改造后编译的jar-->
<dependency><groupId>com.github.pig</groupId><artifactId>pig-cache-cloud-jedis</artifactId><version>2.9.1</version>
</dependency>

部署服务war

这一步直接参考 cachecloud 的文档即可

总结

1. 源码，参考pig： https://gitee.com/log4j/pig
2. 关于pig， 这是一套微服务应用的实践基于Spring Cloud、Spring Security Oauth2.0开发企业级认证与授权，提供常见服务监控、链路追踪、日志分析、缓存管理、任务调度等实现
3. 改造写于2017-2018的跨年夜，文章整理与2018.1.1，真惨，不过我喜欢 ?
4. 2017 失去很多，2018本命年 ? 汪汪汪！
