 <!-- flink运行时的webUI -->
 <dependency>
     <groupId>org.apache.flink</groupId>
     <artifactId>flink-runtime-web</artifactId>
     <version>${flink-version}</version>
     <scope>compile</scope>
 </dependency>

// 配置和启动
import org.apache.flink.configuration.Configuration;
import org.apache.flink.configuration.RestOptions;

Configuration configuration = new Configuration();
configuration.setString(RestOptions.BIND_PORT,"8081");
StreamExecutionEnvironment env = StreamExecutionEnvironment.createLocalEnvironmentWithWebUI(configuration);

// 任务启动起来，访问localhost 8081 即可
