Question

我从3.1.1迁移到spring-data-neo4j-rest v3.3.0。在我编译并运行正常之后我发现的是在保存具有空间属性的实体（wkt）时出现错误，该实体应该由LocationIndex索引编制索引。

我得到的错误是：

"exception": "NotFoundException",
"fullname": "org.neo4j.graphdb.NotFoundException",

],

        "org.neo4j.gis.spatial.indexprovider.LayerNodeIndex.add(LayerNodeIndex.java:126)",
        "org.neo4j.gis.spatial.indexprovider.LayerNodeIndex.add(LayerNodeIndex.java:41)",
        "org.neo4j.server.rest.web.DatabaseActions.addToNodeIndex(DatabaseActions.java:708)",
        "org.neo4j.server.rest.web.RestfulGraphDatabase.addToNodeIndex(RestfulGraphDatabase.java:1058)",

        "java.lang.Thread.run(Thread.java:745)"
    ]
}

}

在调用addToIndex方法之前，对象确实具有该属性，因此我看到了检查属性：

@Override
    public <T extends PropertyContainer> void addToIndex(T entity, RestIndex index, String key, Object value) {
        final RestEntity restEntity = (RestEntity) entity; //at this point "wkt":"POINT(-12.130000 51.120000)"
        String uri = restEntity.getUri();       
        if (value instanceof ValueContext) {
            value = ((ValueContext)value).getCorrectValue();
        }
        final Map<String, Object> data = map("key", key, "value", value, "uri", uri);
        final RequestResult result = getRestRequest().post(indexPath(index, null, null), data);
        if (result.statusOtherThan(Status.CREATED)) throw new RuntimeException(String.format("Error adding element %d %s %s to index %s", restEntity.getId(), key, value, index.getIndexName()));
    }

如果我撤消我的更改并返回到v3.1.1，点击相同的数据库（带有空间2.1.2插件的neo4j 2.1.1），它就像魅力一样。

可能是在调用addToIndex方法之前，属性没有保存到数据库中吗？

Spring数据neo4j休息3.3.0错误保存空间索引
