oracle数据源是可以用idesktop打开的，下面是完整的测试代码：
val conf = new SparkConf().setAppName("Guide Example")
conf.set("spark.serializer","org.apache.spark.serializer.KryoSerializer")
conf.set("spark.kryo.registrator", classOf[GeoMesaSparkKryoRegistrator].getName)
conf.setMaster("local[*]")
val sc = new SparkContext(conf)
val params = new util.HashMap[String, java.io.Serializable]()
params.put("dbtype", "oracle")
params.put("host", "localhost")
params.put("port", 1521)//端口号
params.put("schema", "qjdc")//oracle读取时设置为与“User”用户名参数一致即可
params.put("database", "orcl")//数据库名
params.put("user", "qjdc")//用户名
params.put("passwd", "salis")//密码
params.put("numPartitions", 64)//oracle读取时的分区数量，数据量大时可适当增大该值，只用于读取
params.put("partitionField", "partfield")//分区依赖的字段名，有主键时可缺省默认使用主键，无主键时"partitionField"与"predicates"需有一个有效值
params.put("providerType", "JDBC")//引擎类型的唯一标识
val featurerdd = FeatureRDDProviderFactory(params).rdd(new Configuration(), sc, params, new Query("qjdckj_zd_xz"))
val param2 = new util.HashMap[String,java.io.Serializable]()
param2.put("dbType", "UDBX")
param2.put("server", "D:\\2-code\\2-test\\test.udbx")
param2.put("providerType", "SDX")
FeatureRDDProviderFactory(param2).save(featurerdd, param2, featurerdd.schema.getTypeName)
