public void getStudentName() throws IOException { Properties properties = new Properties(); properties.put("driver", ApplicationYmlUtils.getDataSourceDriverClassName()); properties.put("user", ApplicationYmlUtils.getDataSourceUsern.

Spark报错:org.apache.spark.SparkException: Task not serializable一眼就能看出是没有进行序列化，在spark程序中，所有的class都要序列化。如果不需要序列化的用transient修饰修改后的代码:package com.example.controller;import org.apache.spark.api.java.JavaPairRDD;import org.apache.spark.api.java.JavaRDD;
