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> </dependency> <dependency> <groupId>com.sohu.tv</groupId> <artifactId>cachecloud-open-client-redis</artifactId> <version>1.0-SNAPSHOT</version> <exclusions> <exclusion> <artifactId>jedis</artifactId> <groupId>redis.clients</groupId> </exclusion> </exclusions> </dependency> <!--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
- 源码，参考pig： https://gitee.com/log4j/pig
- 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
- 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
- 2017 失去很多，2018本命年 汪汪汪！
