Spring boot 集成Kafka+Storm
由于业务需求需要把Strom与kafka整合到spring boot项目里,实现其他服务输出日志至kafka订阅话题,storm实时处理该话题完成数据监控及其他数据统计,但是网上教程较少,今天想写的就是如何整合storm+kafka 到spring boot,顺带说一说我遇到的坑。
使用工具及环境配置
1. java 版本jdk-1.8
2. 编译工具使用IDEA-2017
3. maven作为项目管理
4.spring boot-1.5.8.RELEASE
需求体现
1.为什么需要整合到spring boot
为了使用spring boot 统一管理各种微服务,及同时避免多个分散配置
2.具体思路及整合原因
使用spring boot统一管理kafka、storm、redis等所需要的bean,通过其他服务日志收集至Kafka,KafKa实时发送日志至storm,在strom bolt时进行相应的处理操作
遇到的问题
1.使用spring boot并没有相关整合storm
2.以spring boot启动方式不知道如何触发提交Topolgy
3.提交Topology时遇到numbis not client localhost 问题
4.Storm bolt中无法通过注解获得实例化bean进行相应的操作
解决思路
在整合之前我们需要知道相应的spring boot 的启动方式及配置(如果你在阅读本文时，默认你已经对storm,kafka及spring boot有相关了解及使用)
-
spring boot 对storm进行整合的例子在网上很少，但是因为有相应的需求,因此我们还是需要整合.
首先导入所需要jar包:
<dependency> <groupId>org.apache.kafka</groupId> <artifactId>kafka-clients</artifactId> <version>0.10.1.1</version> </dependency> <dependency> <groupId>org.springframework.cloud</groupId>

其中去除jar包是因为需要相与项目构建依赖有多重依赖问题,storm版本为1.1.0 spring boot相关依赖为
```java

ps:maven的jar包仅因为项目使用需求,不是最精简,仅供大家参考.
项目结构:
config-存储不同环境配置文件
存储构建spring boot 相关实现类 其他如构建名
启动spring boot的时候我们会发现
- 其实开始整合前,对storm了解的较少,属于刚开始没有接触过,后面参考发现整合到spring boot里面启动spring boot之后并没有相应的方式去触发提交Topolgy的函数,所以也造成了以为启动spring boot之后就完事了结果等了半个小时什么事情都没发生….-。-才发现没有实现触发提交函数.
为了解决这个问题我的想法是: 启动spring boot->创建kafka监听Topic然后启动Topolgy完成启动,可是这样的问题kafka监听这个主题会重复触发Topolgy,这明显不是我们想要的.看了一会后发现spring 有相关启动完成之后执行某个时间方法,这个对我来说简直是救星啊.所以现在触发Topolgy的思路变为:
启动spring boot ->执行触发方法->完成相应的触发条件
构建方法为:
/**
* @author Leezer
* @date 2017/12/28
* spring加载完后自动自动提交Topology
**/
@Configuration
@Component
public class AutoLoad implements ApplicationListener<ContextRefreshedEvent> {
private static String BROKERZKSTR;
private static String TOPIC;
private static String HOST;
private static String PORT;
public AutoLoad(@Value("${storm.brokerZkstr}") String brokerZkstr,
@Value("${zookeeper.host}") String host,
@Value("${zookeeper.port}") String port,
@Value("${kafka.default-topic}") String topic
){
BROKERZKSTR = brokerZkstr;
HOST= host;
TOPIC= topic;
PORT= port;
}
@Override
public void onApplicationEvent(ContextRefreshedEvent event) {
try {
//实例化topologyBuilder类。
TopologyBuilder topologyBuilder = new TopologyBuilder();
//设置喷发节点并分配并发数，该并发数将会控制该对象在集群中的线程数。
BrokerHosts brokerHosts = new ZkHosts(BROKERZKSTR);
// 配置Kafka订阅的Topic，以及zookeeper中数据节点目录和名字
SpoutConfig spoutConfig = new SpoutConfig(brokerHosts, TOPIC, "/storm", "s32");
spoutConfig.scheme = new SchemeAsMultiScheme(new StringScheme());
spoutConfig.zkServers = Collections.singletonList(HOST);
spoutConfig.zkPort = Integer.parseInt(PORT);
//从Kafka最新输出日志读取
spoutConfig.startOffsetTime = OffsetRequest.LatestTime();
KafkaSpout receiver = new KafkaSpout(spoutConfig);
topologyBuilder.setSpout("kafka-spout", receiver, 1).setNumTasks(2);
topologyBuilder.setBolt("alarm-bolt", new AlarmBolt(), 1).setNumTasks(2).shuffleGrouping("kafka-spout");
Config config = new Config();
config.setDebug(false);
/*设置该topology在storm集群中要抢占的资源slot数，一个slot对应这supervisor节点上的以个worker进程,如果你分配的spot数超过了你的物理节点所拥有的worker数目的话，有可能提交不成功，加入你的集群上面已经有了一些topology而现在还剩下2个worker资源，如果你在代码里分配4个给你的topology的话，那么这个topology可以提交但是提交以后你会发现并没有运行。 而当你kill掉一些topology后释放了一些slot后你的这个topology就会恢复正常运行。
*/
config.setNumWorkers(1);
LocalCluster cluster = new LocalCluster();
cluster.submitTopology("kafka-spout", config, topologyBuilder.createTopology());
} catch (Exception e) {
e.printStackTrace();
}
}
}
注:
- 启动项目时因为使用的是内嵌tomcat进行启动,可能会报如下错误
[Tomcat-startStop-1] ERROR o.a.c.c.ContainerBase - A child container failed during start java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Tomcat].StandardHost[localhost].TomcatEmbeddedContext[]] at java.util.concurrent.FutureTask.report(FutureTask.java:122) ~[?:1.8.0_144] at java.util.concurrent.FutureTask.get(FutureTask.java:192) ~[?:1.8.0_144] at org.apache.catalina.core.ContainerBase.startInternal(ContainerBase.java:939) [tomcat-embed-core-8.5.23.jar:8.5.23] at org.apache.catalina.core.StandardHost.startInternal(StandardHost.java:872) [tomcat-embed-core-8.5.23.jar:8.5.23] at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) [tomcat-embed-core-8.5.23.jar:8.5.23] at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1419) [tomcat-embed-core-8.5.23.jar:8.5.23] at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1409) [tomcat-embed-core-8.5.23.jar:8.5.23] at java.util.concurrent.FutureTask.run$$$capture(FutureTask.java:266) [?:1.8.0_144] at java.util.concurrent.FutureTask.run(FutureTask.java) [?:1.8.0_144] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) [?:1.8.0_144] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) [?:1.8.0_144] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_144]
这是因为有相应导入的jar包引入了servlet-api版本低于内嵌版本,我们需要做的就是打开maven依赖把其去除
<exclusion> <artifactId>servlet-api</artifactId> <groupId>javax.servlet</groupId> </exclusion>
然后重新启动就可以了.

启动过程中还有可能报:
org.apache.storm.utils.NimbusLeaderNotFoundException: Could not find leader nimbus from seed hosts [localhost]. Did you specify a valid list of nimbus hosts for config nimbus.seeds?at org.apache.storm.utils.NimbusClient.getConfiguredClientAs(NimbusClient.java:90
这个问题我思考了很久,发现网上的解释都是因为storm配置问题导致不对,可是我的storm是部署在服务器上的.并没有相关的配置,按理也应该去服务器上读取相关配置,可是结果并不是这样的。最后尝试了几个做法发现都不对,这里才发现,在构建集群的时候storm提供了相应的本地集群
LocalCluster cluster = new LocalCluster();
进行本地测试,如果在本地测试就使用其进行部署测试，如果部署到服务器上需要把:
cluster.submitTopology("kafka-spout", config, topologyBuilder.createTopology()); //修正为: StormSubmitter.submitTopology("kafka-spout", config, topologyBuilder.createTopology());进行任务提交;
以上解决了上面所述的问题1-3
问题4:是在bolt中使用相关bean实例,我发现我把其使用@Component加入spring中也无法获取到实例:我的猜想是在我们构建提交Topolgy的时候，它会在:
topologyBuilder.setBolt("alarm-bolt",new AlarmBolt(),1).setNumTasks(2).shuffleGrouping("kafka-spout");执行bolt相关:
@Override public void prepare(Map stormConf, TopologyContext context, OutputCollector collector) { this.collector = collector; StormLauncher stormLauncher = StormLauncher.getStormLauncher(); dataRepositorys =(AlarmDataRepositorys) stormLauncher.getBean("alarmdataRepositorys"); }而不会实例化bolt,导致线程不一而spring 获取不到.（这里我也不是太明白,如果有大佬知道可以分享一波)
而我们使用spring boot的意义就在于这些获取这些繁杂的对象,这个问题困扰了我很久.最终想到,我们可以通过上下文getbean获取实例不知道能不能行,然后我就开始了定义:
例如我需要在bolt中使用一个服务:
/** * @author Leezer * @date 2017/12/27 * 存储操作失败时间 **/ @Service("alarmdataRepositorys") public class AlarmDataRepositorys extends RedisBase implements IAlarmDataRepositorys { private static final String ERRO = "erro"; /** * @param type 类型 * @param key key值 * @return 错误次数 **/ @Override public String getErrNumFromRedis(String type,String key) { if(type==null || key == null){ return null; }else { ValueOperations<String, String> valueOper = primaryStringRedisTemplate.opsForValue(); return valueOper.get(String.format("%s:%s:%s",ERRO,type,key)); } } /** * @param type 错误类型 * @param key key值 * @param value 存储值 **/ @Override public void setErrNumToRedis(String type, String key,String value) { try { ValueOperations<String, String> valueOper = primaryStringRedisTemplate.opsForValue(); valueOper.set(String.format("%s:%s:%s", ERRO,type, key), value, Dictionaries.ApiKeyDayOfLifeCycle, TimeUnit.SECONDS); }catch (Exception e){ logger.info(Dictionaries.REDIS_ERROR_PREFIX+String.format("key为%s存入redis失败",key)); } }这里我指定了该bean的名称,则在bolt执行prepare时:使用getbean方法获取了相关bean就能完成相应的操作.
然后kafka订阅主题发送至我bolt进行相关的处理.而这里getbean的方法是在启动bootmain函数定义:
@SpringBootApplication
@EnableTransactionManagement
@ComponentScan({"service","storm"})
@EnableMongoRepositories(basePackages = {"storm"})
@PropertySource(value = {"classpath:service.properties", "classpath:application.properties","classpath:storm.properties"})
@ImportResource(locations = {
"classpath:/configs/spring-hadoop.xml",
"classpath:/configs/spring-hbase.xml"})
public class StormLauncher extends SpringBootServletInitializer {
//设置 安全线程launcher实例
private volatile static StormLauncher stormLauncher;
//设置上下文
private ApplicationContext context;
public static void main(String[] args) {
SpringApplicationBuilder application = new SpringApplicationBuilder(StormLauncher.class);
// application.web(false).run(args);该方式是spring boot不以web形式启动
application.run(args);
StormLauncher s = new StormLauncher();
s.setApplicationContext(application.context());
setStormLauncher(s);
}
private static void setStormLauncher(StormLauncher stormLauncher) {
StormLauncher.stormLauncher = stormLauncher;
}
public static StormLauncher getStormLauncher() {
return stormLauncher;
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(StormLauncher.class);
}
/**
* 获取上下文
*
* @return the application context
*/
public ApplicationContext getApplicationContext() {
return context;
}
/**
* 设置上下文.
*
* @param appContext 上下文
*/
private void setApplicationContext(ApplicationContext appContext) {
this.context = appContext;
}
/**
* 通过自定义name获取 实例 Bean.
*
* @param name the name
* @return the bean
*/
public Object getBean(String name) {
return context.getBean(name);
}
/**
* 通过class获取Bean.
*
* @param <T> the type parameter
* @param clazz the clazz
* @return the bean
*/
public <T> T getBean(Class<T> clazz) {
return context.getBean(clazz);
}
/**
* 通过name,以及Clazz返回指定的Bean
*
* @param <T> the type parameter
* @param name the name
* @param clazz the clazz
* @return the bean
*/
public <T> T getBean(String name, Class<T> clazz) {
return context.getBean(name, clazz);
}
到此集成storm 和kafka至spring boot已经结束了,相关kafka及其他配置我会放入github上面
对了这里还有一个kafkaclient的坑:
Async loop died! java.lang.NoSuchMethodError: org.apache.kafka.common.network.NetworkSend.
项目会报kafka client 问题,这是因为storm-kafka中，kafka使用的是0.8版本,而NetworkSend是0.9以上的版本,这里集成需要与你集成的kafka相关版本一致.
虽然集成比较简单,但是参考都比较少,加之刚开始接触storm所以思考比较多,也在这记录一下.
