Spring Data Neo4j 4没有存储任何数据
我在新项目中使用neo4j-2.3.1和spring-data-neo4j 4。我将所有内容都设置为post（Spring Data Neo4j 4）。但是，我不能将任何数据存储到数据库中。 这是我的neo4j配置：
@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();
}
}
这是REST api，它只是简单地调用存储库来存储对象：
@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);
}
这是存储库：
@Repository
@Transactional
public interface ProjectRepository extends GraphRepository<Project> {
}
这是Project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);
}
}
我做了一个卷发帖后，一切正常，没有任何异常和错误。然后我去localhost：7474获取所有数据，我什么都没得到。 这是日志，我做了一个卷曲的帖子和卷曲得到。没有任何例外

转换器不正确 - 它说从Project转换为String而不是Map转换为String。
已经存在针对泛型问题的错误，因此在修复之前，您必须省略它们并使用它们：
@Convert(MapJson.class)
private Map attributes;
使用属性转换器
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
}
}
