如何使用GraphX的Java API获取图的已连接组件的列表

SparkSession spark = SparkSession.builder()
                .appName("GraphXJavaAPI")
                .master("local[*]")
                .getOrCreate();

JavaRDD<Tuple2<Object, Object>> edges = spark.read()
                .textFile("path/to/edges/file")
                .javaRDD()
                .map(line -> {
                    String[] parts = line.split(" ");
                    return new Tuple2<>(Long.parseLong(parts[0]), Long.parseLong(parts[1]));
                });

Graph<Object, Object> graph = Graph.fromEdgeTuples(edges.rdd(), null, StorageLevel.MEMORY_ONLY(),
                StorageLevel.MEMORY_ONLY(), scala.reflect.ClassTag$.MODULE$.apply(Object.class),
                scala.reflect.ClassTag$.MODULE$.apply(Object.class));

ConnectedComponents<Object> connectedComponents = graph.ops().connectedComponents();
JavaRDD<Tuple2<Object, Object>> componentList = connectedComponents
                .run().toJavaRDD();

componentList.foreach(component -> System.out.println(component._1() + " belongs to component " + component._2()));
