Question

我一直在尝试使用简单测试类中的GeoMesa api插入到Cassandra表中。最后，我需要将点数据插入到Cassandra表中，该表具有来自Spark流工作的复合键，但是为了简单地证明它，我只是尝试使用在简单应用类中使用CassandraDataStore的在线GeoMesa api代码。。问题是，由于几个GeoMesa类正在使用的typesafe日志库中的LazyLogging类，我继续遇到编译错误。排除Gradle中的依赖性没有任何影响。这有什么办法吗？代码和例外如下。

代码：

import java.util

object Application extends Serializable {

def main(args: Array[String]): Unit = {

val parameters = new util.HashMap[String, String]
parameters.put("geomesa.cassandra.contact.point", "localhost:9042")
parameters.put("geomesa.cassandra.keyspace", "tgeomesa")
parameters.put("geomesa.cassandra.catalog.table", "tstwrite")

val dataStore:org.geotools.data.DataStore =
  org.geotools.data.DataStoreFinder.getDataStore(parameters)

println("Completed")
}

}

// GeoMesa
compile group: 'org.locationtech.geomesa', name: 'geomesa-cassandra-datastore_2.11', version: '1.3.4'
compile group: 'org.geotools', name: 'gt-main', version: '15.1'

斯卡拉：2.11.8 GeoMesa：1.3.4 卡珊德拉：3.0.15

谢谢。
