Cannot resolve method addSource
原始代碼如下:
ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
BatchTableEnvironment tableEnv = BatchTableEnvironment.create(env);
DataStream<Row> source = env.addSource(new RichSourceFunction<Row>() ...
Intellij提示:
Cannot resolve method 'addSource(anonymous org.apache.flink.streaming.api.functions.source.RichSourceFunction<org.apache.flink.types.Row>)'
設法改成:
ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
StreamTableEnvironment tableEnv = StreamTableEnvironment.create(env);
Intellij提示:
in create(org.apache.flink.streaming.api.environment.StreamExecutionEnvironment)
StreamTableEnvironment
cannot be applied to
(org.apache.flink.api.java.ExecutionEnvironment)
再次設法改成:
StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
StreamTableEnvironment tEnv = StreamTableEnvironment.create(env);
