Spring Data Neo4j 4没有存储任何数据

我在我的新项目中使用了neo4j-2.3.1和spring-data-neo4j 4。我将这一切设置为post（Spring Data Neo4j 4）。但是，我不能将任何数据存储到数据库中。这里是我的Neo4j配置：Spring Data Neo4j 4没有存储任何数据

@Configuration 
@EnableNeo4jRepositories("org.drexel.cas.repository") 
@EnableTransactionManagement 
@ComponentScan("org.drexel.cas") 
public class RootConfig extends Neo4jConfiguration { 
    @Override 
    public SessionFactory getSessionFactory() { 
     return new SessionFactory("org.drexel.cas.domain"); 
    } 
    @Bean 
    public Neo4jServer neo4jServer() { 
     return new RemoteServer("http://localhost:7474", "neo4j", "xxxxxx"); 
    } 
    @Override 
    @Bean 
    @Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS) 
    public Session getSession() throws Exception { 
     return super.getSession(); 
    } 
}

这里是REST API，它只是简单地调用库中存储的对象：

@Autowired 
ProjectRepository repository; 

@RequestMapping(value = "project", method = POST, consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE) 
public ResponseEntity<Project> create(@RequestBody Map<String, Object> param) { 
    Project project = new Project(param); 
    repository.save(project); 
    return ResponseEntity.ok(project); 
}

这里是仓库：

@Repository 
@Transactional 
public interface ProjectRepository extends GraphRepository<Project> { 

}

这是项目类：

@NodeEntity 
public class Project { 
@GraphId 
private Long id; 
@Convert(MapJson.class) 
private Map<String, Object> attributes; 

public Project() { 
    this.attributes = new HashMap<>(); 
} 

public Project(Map<String, Object> params) { 
    id = System.currentTimeMillis(); 
    this.attributes = params; 
} 

public boolean equals(Object object) { 
    if (object == null) 
     return false; 
    if (!(object instanceof Project)) 
     return false; 
    Project other = (Project) object; 
    if (!other.getId().equals(this.id)) 
     return false; 
    return true; 
} 

public int hashCode() { 
    return this.id.hashCode(); 
} 

}

这里是转换器类：

public class MapJson implements AttributeConverter<Map<String, Object>, String> { 

    @Override 
    public String toGraphProperty(Map<String, Object> value) { 
     Gson gson = new Gson(); 
       Type type = new TokenType<Map<String, Object>>(){}.getType(); 
       return gson.toJson(value, type); 
      } 

      @Override 
      public Map<String, Object> toEntityAttribute(String value) { 
       Gson gson = new Gson(); 
       Type type = new TokenType<Map<String, Object>>(){}.getType(); 
       return gson.fromJson(value, type); 
      } 

     }

后，我做出卷曲后，一切正常，并没有任何异常和错误。然后我去localhost：7474获取所有数据，我什么也没得到。这是日志，我做了一个卷曲贴和卷曲得到。没有任何异常

没有例外。有谁知道如何解决它？

请提供更多信息。你的项目实体是什么样的，SDN是如何配置的？日志中的任何例外情况？ – Luanne

@Luanne我添加了你问的信息。日志中没有任何例外。 –

你的转换器是什么样的？ – Luanne

尽量不要自己设置@GraphId属性的值。

public Project(Map<String, Object> params) { 
    //id = System.currentTimeMillis(); 
    this.attributes = params; 
}

转换器本身和引线不它说转换从Project到String，而不是Map到String。

目前已经开放了泛型问题中的错误，所以到那是固定的，你必须忽略它们，并使用来代替：

@Convert(MapJson.class) 
private Map attributes;

与属性转换

public class MapJson implements AttributeConverter<Map,String> { 

    @Override 
    public String toGraphProperty(Map value) { 
     //do something 
    } 

    @Override 
    public Map<String, Object> toEntityAttribute(String value) { 
     //do something 
    } 
}

即时通讯对不起，这是一个错字错误，我没有使用AttributeConverter ，String>。如果我有泛型问题，则不能编译代码。但是，我没有得到任何例外 –

当我使用它时，绝对有一个运行时异常。 – Luanne
