使用Spring Data neo4j创建空间索引时出错

我正在研究Neo4j Spring Data项目，并希望在节点上执行一些与空间相关的操作。

实体类

@NodeEntity public class User { @GraphId Long id; private String fname; private String lname; private String uname; private String pwd; private Double latitude, longitude; @Indexed(indexType = IndexType.POINT, indexName = "geom") private String wkt; public void setLocation(Double lon, Double lat) { this.wkt = String.format("POINT( %.2f %.2f )", lon, lat); } @RelatedTo(type = "KNOWS", direction = Direction.OUTGOING) public Set knows; //getter and setter methods 

调节器

  @RequestMapping(path = URI_SAVE, method = RequestMethod.POST) public String handleUriSave(@ModelAttribute(value = "insuser") User user) { System.out.println("save method called"); System.out.println("User : " + user); try { User retrivedUser = userService.findUser(user); if (retrivedUser != null) { if (retrivedUser.getUname().equals(user.getUname())) { throw new Exception("User Already Exist !!"); } } user.setLocation(user.getLongitude(), user.getLatitude()); userService.create(user); 

UserServiceImpl

  @Service public class UserServiceImpl implements IUserService { @Autowired private UserEntityRepository userrepository; @Override public User create(User user) { return userrepository.save(user); } 

UserEntityRepository

 import org.springframework.data.neo4j.repository.GraphRepository; import org.springframework.data.neo4j.repository.SpatialRepository; import org.springframework.stereotype.Repository; import com.ga.data.entity.User; @Repository public interface UserEntityRepository extends GraphRepository, SpatialRepository { User findByUname(String uname); } 

在保存用户时它会给出exception，

例外

  java.lang.RuntimeException: Erroraddingelement0wktPOINT(85.4225.02)toindexgeomstatus500{ "message": "No such property, 'wkt'.", "exception": "NotFoundException", "fullname": "org.neo4j.graphdb.NotFoundException", "stackTrace": [ "org.neo4j.kernel.impl.core.NodeProxy.getProperty(NodeProxy.java:469)", "org.n xNodeWrapper.addNode(LegacyIndexNodeWrapper.java:52)", "org.neo4j.kernel.impl.api.StateHandlingStatementOperations.nodeAddToLegacyIndex(StateHandlingStatementOperations.java:1420)", "org.neo4j.kernel.impl.api.Ope LegacyIndexProxy.java:390)", "org.neo4j.server.rest.web.DatabaseActions.addToNodeIndex(DatabaseActions.java:699)", "org.neo4j.server.rest.web.RestfulGraphDatabase.addToNodeIndex(RestfulGraphDatabase.java:1059)", " java:745)" ], "errors": [ { "code": "Neo.DatabaseError.General.UnknownFailure", "message": "No such property, 'wkt'.", "stackTrace": "org.neo4j.graphdb.NotFoundException: No such property, 'wkt'.\r\n\tat org.neo4j.kernel x.add(LayerNodeIndex.java:41)\r\n\tat org.neo4j.gis.spatial.indexprovider.LegacyIndexNodeWrapper.addNode(LegacyIndexNodeWrapper.java:52)\r\n\tat org.neo4j.kernel.impl.api.StateHandlingStatementOperations.nodeAd egacyIndexProxy.internalAdd(LegacyIndexProxy.java:536)\r\n\tat org.neo4j.kernel.impl.coreapi.LegacyIndexProxy.add(LegacyIndexProxy.java:390)\r\n\tat org.neo4j.server.rest.web.DatabaseActions.addToNodeIndex(Data reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)\r\n\tat java.lang.reflect.Method.invoke(Method.java:606)\r\n\tat com.sun.jersey.spi.container.JavaMethodInvokerFactory$1.invoke( her.dispatch(ResourceJavaMethodDispatcher.java:75)\r\n\tat org.neo4j.server.rest.transactional.TransactionalRequestDispatcher.dispatch(TransactionalRequestDispatcher.java:139)\r\n\tat com.sun.jersey.server.impl ri.rules.RightHandPathRule.accept(RightHandPathRule.java:147)\r\n\tat com.sun.jersey.server.impl.uri.rules.RootResourceClassesRule.accept(RootResourceClassesRule.java:84)\r\n\tat com.sun.jersey.server.impl.appl 9)\r\n\tat com.sun.jersey.server.impl.application.WebApplicationImpl.handleRequest(WebApplicationImpl.java:1409)\r\n\tat com.sun.jersey.spi.container.servlet.WebComponent.service(WebComponent.java:409)\r\n\tat ervletHolder.handle(ServletHolder.java:800)\r\n\tat org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1669)\r\n\tat org.neo4j.server.rest.web.CollectUserAgentFilter.doFilter(Coll a:221)\r\n\tat org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1125)\r\n\tat org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:515)\r\n\tat org.eclipse.jetty.serv ndle(HandlerList.java:52)\r\n\tat org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:97)\r\n\tat org.eclipse.jetty.server.Server.handle(Server.java:497)\r\n\tat org.eclipse.jetty.server. a:620)\r\n\tat org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:540)\r\n\tat java.lang.Thread.run(Thread.java:745)\r\n" } ] } 

我是neo4j DB的新手。 我已经阅读了一些文章并在neo4j中通过REST API创建了索引，但使用spring数据创建neo4j会产生这种类型的exception。 我正在使用neo4j-community-2.3.1-windows版本和spring-data-neo4j 3.4.0 RELEASE版本。

任何建议请。

Answer 1

您使用的是哪个版本的spring-data-neo4j？ 你在使用spring-data-neo4j-rest吗？ 还是嵌入在服务器中？

这是以前存在的用户吗？

在exception中似乎缺少一些堆栈跟踪。

你能用unit testing重新制作它吗？
