代码就是flink自带的例子。
public class WordCountStreamingByJava {
public static void main(String[] args) throws Exception {
// 创建执行环境
StreamExecutionEnvironment env =
StreamExecutionEnvironment.getExecutionEnvironment();
// 设置socket数据源
DataStreamSource<String> source = env.socketTextStream("zongteng75", 9001,
"\n");
// 转化处理数据
DataStream<WordWithCount> dataStream = source.flatMap(new
FlatMapFunction<String, WordWithCount>() {
@Override
public void flatMap(String line, Collector<WordWithCount> collector) throws
Exception {
System.out.println(line);
for (String word : line.split(" ")) {
collector.collect(new WordWithCount(word, 1));
}
}
}).keyBy("word")//以key分组统计
.timeWindow(Time.seconds(2),Time.seconds(2))//设置一个窗口函数，模拟数据流动
.sum("count");//计算时间窗口内的词语个数
// 输出数据到目的端
dataStream.print();
// 执行任务操作
env.execute("Flink Streaming Word Count By Java");
}
我现在加了flink环境变量 这个例子 可以过了。就很奇怪
