SpringBoot集成neo4j示例

SpringBoot集成neo4j

配置

• xml配置：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-neo4j</artifactId>
     <version>2.1.9.RELEASE</version>
</dependency>

• SpringBoot配置:

@SpringBootApplication
@EnableNeo4jRepositories
public class TestApplication {
   

    public static void main(String[] args) {
   
        SpringApplication.run(TestApplication.class, args);
    }

}

到这里SpringBoot配置完成，接下来是增删改查

• 实体类

1. 节点类

@Data
@NoArgsConstructor
@NodeEntity
public class Bill {
   

    @Id @GeneratedValue
    private Long id;

    @Property
    private Integer billNo;
    @Property
    private String name;
    @Property
    private BigDecimal quantity;

}

2. 关系类

@RelationshipEntity(type = "MERGE")
@Data
@NoArgsConstructor
