springboot集成调用Azkaban

springboot集成调用Azkaban

 

一、 说明

  1.Azkaban是由Linkedin公司推出的一个批量工作流任务调度器,主要用于在一个工作流内以一个特定的顺序运行一组工作和流程,它的配置是通过简单的key:value对的方式,通过配置中的dependencies 来设置依赖关系,这个依赖关系必须是无环的,否则会被视为无效的工作流。Azkaban使用job配置文件建立任务之间的依赖关系,并提供一个易于使用的web用户界面维护和跟踪你的工作流。

        2.springboot版本:2.0.5  azkaban版本:3.59.0

 

二、maven依赖

        <dependency>
            <groupId>com.google.code.gson</groupId>
            <artifactId>gson</artifactId>
            <version>2.8.5</version>
        </dependency>
        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-pool2</artifactId>
            <version>2.5.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpcore</artifactId>

            <version>2.9.7</version>
        </dependency>

三、代码

  1.azkaban配置文件(注意需要在启动类@PropertySource标签中引入读取该配置文件)

monitor.azkaban.username=azkaban
monitor.azkaban.password=azkaban
monitor.azkaban.url=http://192.168.11.12:8081
monitor.azkaban.connectTimeout=60000
monitor.azkaban.readTimeout=120000
azkaban.properties

  2.azkaban配置实体类

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.client.SimpleClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;

@Configuration
public class AzkabanConfig {
    @Value("${monitor.azkaban.username}")
    private String azkUsername;
    @Value("${monitor.azkaban.password}")
    private String azkPassword;
    @Value("${monitor.azkaban.url}")
    private String azkUrl;
    @Value("${monitor.azkaban.connectTimeout}")
    private int connectTimeout;
    @Value("${monitor.azkaban.readTimeout}")
    private int readTimeout;

    @Bean
    public RestTemplate getRestTemplate() {
        SimpleClientHttpRequestFactory requestFactory = new SimpleClientHttpRequestFactory();
        requestFactory.setConnectTimeout(connectTimeout);
        requestFactory.setReadTimeout(readTimeout);
        RestTemplate restTemplate = new RestTemplate(requestFactory);
        return restTemplate;
    }

    public String getAzkUsername() {
        return azkUsername;
    }

    public void setAzkUsername(String azkUsername) {
        this.azkUsername = azkUsername;
    }

    public String getAzkPassword() {
        return azkPassword;
    }

    public void setAzkPassword(String azkPassword) {
        this.azkPassword = azkPassword;
    }

    public String getAzkUrl() {
        return azkUrl;
    }

    public void setAzkUrl(String azkUrl) {
        this.azkUrl = azkUrl;
    }

}
AzkabanConfig

  3.HttpClient配置SSL绕过https证书 

import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.X509Certificate;

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

public class SSLUtil {

    private static final String PROTOCOL = "SSL";
    private static final TrustManager[] UNQUESTIONING_TRUST_MANAGER = new TrustManager[] { new X509TrustManager() {

        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return null;
        }

        public void checkClientTrusted(X509Certificate[] certs, String authType) {
        }

        public void checkServerTrusted(X509Certificate[] certs, String authType) {
        }
    } };

    private SSLUtil() {
    }

    public static void turnOffSslChecking() throws NoSuchAlgorithmException, KeyManagementException {
        final SSLContext sc = SSLContext.getInstance(PROTOCOL);
        sc.init(null, UNQUESTIONING_TRUST_MANAGER, null);
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    }

    public static void turnOnSslChecking() throws KeyManagementException, NoSuchAlgorithmException {
        SSLContext.getInstance(PROTOCOL).init(null, null, null);
    }
}
SSLUtil

  4.常量类

public interface SysContants {
    
        /**azkaban成功状态**/
    String AZK_SUCCESS = "success";
    
}
SysContants

  5.根据azkaban返回数据定制实体类(注释少抱歉)

  8.调用demo

    /**
     * 根据flowId 立即执行任务
     * @param projectName 项目名称
     * @param flow 流id
     * @throws CommonException 阿兹卡班异常
     */

            throw new CommonException("调度初始化完毕,立即执行任务异常",e);
        }
    }
demo

 

四、注意

  1.如遇报错情况,请关注azkaban相关log日志。

  2.如果pom文件jar包不全 请评论。
