剛開始按網上博客搭建 spring boot 和 neo4j一直報sessionFactory找不到，直到下載了spring-data-neo4j的實例demo對比才搭建成功，而且用戶名是neo4j，不是創建一個數據庫時的名字，搞了幾個小時終於搞成功了。以后還是多看官方文檔，搜來搜去，什么鬼都搜不到。記錄一下自己踩的坑。

pom文件
是springboot進行過封裝的spring-boot-starter-data-neo4j提供了一些基礎的方法,有點像spring-data-jpa

dao類
-
@Repository
-
public
interface UserRepository extends Neo4jRepository<UserNode,Long>{
-
-
}
測試類
-
@Component
-
public
class UserRepositoryTest extends Neo4jDemoApplicationTests{
-
-
Logger logger = LoggerFactory.getLogger(UserRepositoryTest.class);
-
-
@Autowired
-
UserRepository userRepository;
-
-
@Test
-
public void createUserNode(){
-
System.out.println(userRepository);
-
UserNode userNode =
new UserNode();
-
userNode.setName(
"xupan");
-
userNode.setUserId(
"123");
-
UserNode save = userRepository.save(userNode);
-
logger.info(save.toString());
-
Assert.assertTrue(save!=
null);
-
}
-
-
@Test
-
public void delAll(){
-
userRepository.deleteById(
new Long(
27));
-
-
}
-
}
啟動類的@EnableNeo4jRepositories一定要加
-
@SpringBootApplication
-
@EnableNeo4jRepositories
-
public
class Neo4jDemoApplication {
-
-
public static void main(String[] args) {
-
SpringApplication.run(Neo4jDemoApplication.class, args);
-
}
-
}
Application.yml
-
spring:
-
data:
-
neo4j:
-
uri: bolt:
//localhost:7687
-
username: neo4j
-
password:
