1.安裝zookeeper 3.6.3（elastic-job實現http類型作業 要求zookeeper版本在3.6以上）

1.1 pom.xml

<dependency><groupId>org.apache.shardingsphere.elasticjob</groupId><artifactId>elasticjob-lite-spring-boot-starter</artifactId><version>3.0.1</version></dependency><dependency><groupId>org.apache.shardingsphere.elasticjob</groupId><artifactId>elasticjob-lite-lifecycle</artifactId><version>3.0.1</version></dependency>

1.2 配置文件

elasticjob.reg-center.server-lists=127.0.0.1:2181 elasticjob.reg-center.namespace=elastic-job-zhangmr elasticjob.reg-center.maxRetries=3 elasticjob.reg-center.baseSleepTimeMilliseconds=1000 elasticjob.reg-center.maxSleepTimeMilliseconds=3000 elasticjob.reg-center.session-timeout-milliseconds=3000 elasticjob.reg-center.connection-timeout-milliseconds=3000 elasticjob.shardingTotalCount = 4

1.3 demo代碼

@Service public class TaskServer {@Value("${elasticjob.reg-center.server-lists}")private String serverLists;@Value("${elasticjob.reg-center.namespace}")private String namespace;@Value("${elasticjob.shardingTotalCount}")private int shardingTotalCount;@Autowiredprivate ZookeeperRegistryCenter zookeeperRegistryCenter;public void addTask(){JobConfiguration jobConfiguration = JobConfiguration.newBuilder("javaHttpJob", shardingTotalCount).setProperty(HttpJobProperties.URI_KEY, "http://127.0.0.1:8082/job/excutor").setProperty(HttpJobProperties.METHOD_KEY, "POST").setProperty(HttpJobProperties.DATA_KEY, "source=ejob").cron("* * * * * ? *").shardingItemParameters("0=test0,1=test1, 2=test2, 3=test3").failover(true).misfire(true).overwrite(true).build();ScheduleJobBootstrap scheduleJobBootstrap = new ScheduleJobBootstrap(zookeeperRegistryCenter, "HTTP", jobConfiguration);scheduleJobBootstrap.schedule();} }

1.4 調用添加方法

@RestController @RequestMapping("/job") public class TaskController {@Autowiredprivate TaskServer taskServer;@RequestMapping("/excutor")@ResponseBodypublic String excutor(){System.out.println("123");return "log info success";}@RequestMapping("/add")public String add(){taskServer.addTask();return "log info success";} }

1.5 查看zookeeper信息

1.6 查看接口文本信息

注意 ：一開始使用linux服務器上的zookeeper3.6.3,一直連接不上zookeeper ,注冊不上，后來在本地安裝了個zookeeper3.6.3 使用127.0.0.1：2181 可以正常連接（原因是我的linux配置太低，可以把elasticjob.reg-center.session-timeout-milliseconds=300000 elasticjob.reg-center.connection-timeout-milliseconds=300000 這兩個參數調大就可以連上）
