使用java代码提交flink job 任务

转：https://blog.csdn.net/pingweicheng/article/details/118223041

以下代码是使用java程序客户端提交flink job的示例代码

package client;
import org.apache.flink.api.common.ExecutionConfig;
import org.apache.flink.api.common.JobID;
import org.apache.flink.client.deployment.StandaloneClusterId;
import org.apache.flink.client.program.PackagedProgram;
import org.apache.flink.client.program.PackagedProgramUtils;
import org.apache.flink.client.program.rest.RestClusterClient;
import org.apache.flink.configuration.Configuration;
import org.apache.flink.configuration.JobManagerOptions;
import org.apache.flink.configuration.RestOptions;
import org.apache.flink.core.fs.Path;
import org.apache.flink.runtime.jobgraph.JobGraph;
import org.apache.flink.runtime.jobgraph.JobVertex;
import org.apache.flink.runtime.jobgraph.SavepointRestoreSettings;
import org.apache.flink.runtime.jobgraph.tasks.AbstractInvokable;
import org.apache.flink.streaming.api.graph.StreamGraph;
  
import java.io.File;
import java.util.ArrayList;
import java.util.concurrent.CompletableFuture;
