Question

我使用Geomesa Native API在java中执行accumulo客户端。以下是java客户端代码：

package org.locationtech.geomesa.api;
import java.time.ZonedDateTime;
import java.util.*;
import org.geotools.geometry.jts.JTSFactoryFinder;

import com.google.gson.Gson;

import com.vividsolutions.jts.geom.Coordinate;
import com.vividsolutions.jts.geom.GeometryFactory;
public class GeomesaAccumuloClient {
    public static void main(String args[]){
        System.out.println("hello1");
        try {
            GeoMesaIndex<DomainObject> index =
                AccumuloGeoMesaIndex.build(
                        "asd",
                        "localhost:2181",
                        "hps",
                        "root", "9869547580",
                        false,
                        new DomainObjectValueSerializer(),
                        new DefaultSimpleFeatureView<DomainObject>("aj_p"));
        }
        catch(Throwable t) {
            System.err.println("Uncaught exception is detected! " + t
                    + " st: "+ Arrays.toString(t.getStackTrace()));
        }
    }
    public static class DomainObject {
        public final String id;
        public final int intValue;
        public final double doubleValue;

        public DomainObject(String id, int intValue, double doubleValue) {
            this.id = id;
            this.intValue = intValue;
            this.doubleValue = doubleValue;
        }
    }
    public static class DomainObjectValueSerializer implements ValueSerializer<DomainObject> {
        public static final Gson gson = new Gson();
        @Override
        public byte[] toBytes(DomainObject o) {
            System.out.println(gson.toJson(o).toString());
            return gson.toJson(o).getBytes();
        }

        @Override
        public DomainObject fromBytes(byte[] bytes) {
            return gson.fromJson(new String(bytes), DomainObject.class);
        }
    }
    private static Date date(String s) {
        return Date.from(ZonedDateTime.parse(s).toInstant());
    }
}

但是当我使用命令

执行此文件时

accumulo org.locationtech.geomesa.api.GeomesaAccumuloClient

我遇到以下异常：

我已经在GeoMesa 1.3.0和1.3.1的副本上测试了您的代码，我无法直接重现您的问题。但是，我认为正在发生的事情是你以某种方式混合了新旧罐子。在1.3.x系列中

new DefaultSimpleFeatureView<DomainObject>("aj_p")

无效，因为DefaultSimpleFeatureView不接受导致编译失败的参数。删除＆＃34; aj_p＆＃34;并且正在运行

accumulo -add ./geomesa-native-api_2.11-1.3.1.jar org.locationtech.geomesa.api.GeomesaAccumuloClient

似乎工作正常，测试表出现在我的Accumulo实例表中。

我建议您验证类路径上的jar并重新安装或下载GeoMesa jar。
