在使用IgniteDataStreamer插入数据时，有时会在地理空间部分遇到异常，因为它试图删除一行：
org.apache.ignite.internal.processors.query.h2.opt.GridH2SpatialIndex.remove(GridH2SpatialIndex.java:250) ~[ignite-geospatial-2.5.2.jar:2.6.0]
我使用单个数据库（一个具有一个数据库且所有Java应用程序为客户端的集群）进行了测试。
这是“部分”类：
public class LNSData implements Comparable<LNSData>{
@QuerySqlField(index = true)
public Long id;
...
@JsonIgnore
@QuerySqlField(index=true)
Geometry gwGeoCoordinates;
@JsonIgnore
@QuerySqlField(index=true)
Geometry gpsGeoCoordinates;
//constructor, getters, setters
}
两个几何都不应该为空，并且创建为：
WKTReader r = new WKTReader();
try {
gwGeoCoordinates = r.read("POINT(" + gatewayLong + " " + gatewayLat + " " + gatewayAlt +")");
} catch (ParseException e) {
LogManager.getLogger(LNSData.class).catching(e);
}
try {
gpsGeoCoordinates = r.read("POINT(" + gpsLongitude + " " + gpsLatitude + " " + gpsAltitude +")");
} catch (ParseException e) {
LogManager.getLogger(LNSData.class).catching(e);
}
这是流光部分：
TreeMap<Long, LNSData> dataToSave = new TreeMap<>();
try {
for (LNSData lnsData : lLNSData) {
dataToSave.put(lnsData.getId(), lnsData);
}
logger.debug("Calling repository save on " + lLNSData.size() + " elements");
if(stmr == null) {
stmr = databaseConfiguration.igniteInstance().dataStreamer("LNSDataCache");
stmr.autoFlushFrequency(2000);
}
stmr.addData(dataToSave);
}
最后是完整的错误：
