我在我的新項目中使用了neo4j-2.3.1和spring-data-neo4j 4。我將這一切設置爲post（Spring Data Neo4j 4）。但是，我不能將任何數據存儲到數據庫中。 這裏是我的Neo4j配置：Spring Data Neo4j 4沒有存儲任何數據
@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();
}
}
這裏是REST API，它只是簡單地調用庫中存儲的對象：
@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);
}
這裏是倉庫：
@Repository
@Transactional
public interface ProjectRepository extends GraphRepository<Project> {
}
這是項目類：
@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();
}
}
這裏是轉換器類：
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);
}
}
後，我做出捲曲後，一切正常，並沒有任何異常和錯誤。然後我去localhost：7474獲取所有數據，我什麼也沒得到。 這是日誌，我做了一個捲曲貼和捲曲得到。沒有任何異常
