springboot快速集成neo4j

1.导入坐标，我这里是springboot3.0.2

        <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-neo4j</artifactId></dependency>

 

2.写yml

spring:data:neo4j:database: neo4j:uri: bolt://localhost:7687authentication:username: password: 

3.写实体类

举个例子：

 在neo4j中查询，点击表格查看数据结构

 

identity即id，labels标签，一般我们的实体类就是以他为基准

@Node("症状")
@Data
@NoArgsConstructor
public class Symptom {@Id  // 标识这是主键，对应Neo4j的内部id
    @GeneratedValueprivate Long identity;@Property("名称")  // 对应properties中的"名称"属性private String name;
}

 

dao层

public interface SymptomRepository  extends Neo4jRepository<Symptom, Long> {@Query("MATCH (n:`症状`) RETURN n")List<Symptom> findAll();}

service层

@Service
public class SymptomService {@AutowiredSymptomRepository symptomRepository;public List<Symptom>findAll(){List<Symptom> all = symptomRepository.findAll();return all;}
}

controller层

@RestController
@RequestMapping("/collect")
public class CollectController {@AutowiredSymptomService service;@RequestMapping("/all")public Result getAll(){return Result.success(service.findAll());}}
