下载neo4j可以参考

1、pom文件引入neo4j依赖

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

2、application.yml配置

neo4j默认密码为neo4j登录时会提示修改密码 此为修改后的密码

spring:
      data:
        neo4j:
          uri: bolt://127.0.0.1:7687
          username: neo4j
          password: 123

3创建模型Person类

@NodeEntity(label = "Person")
    public class Person {
        @Id
        @GeneratedValue
        private Long nodeId;
    
        @Property(name = "name")
        private String name;
    
        @Property(name = "born")
        private int born;
    
        public Long getNodeId() {
            return nodeId;
        }
    
        public void setNodeId(Long nodeId) {
            this.nodeId = nodeId;
        }
    
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    
        public int getBorn() {
            return born;
        }
    
        public void setBorn(int born) {
            this.born = born;
        }
    }

4、DAO创建 PersonRepository

@Repository
    public interface PersonRepository extends Neo4jRepository<Person, Long> {
    }

Neo4jRepository接口含有的方法

@NoRepositoryBean
    public interface Neo4jRepository<T, ID extends Serializable> extends PagingAndSortingRepository<T, ID> {
        <S extends T> S save(S var1, int var2);
    
        <S extends T> Iterable<S> save(Iterable<S> var1, int var2);
    
        Optional<T> findById(ID var1, int var2);
    
        Iterable<T> findAll();
    
        Iterable<T> findAll(int var1);
    
        Iterable<T> findAll(Sort var1);
    
        Iterable<T> findAll(Sort var1, int var2);
    
        Iterable<T> findAllById(Iterable<ID> var1);
    
        Iterable<T> findAllById(Iterable<ID> var1, int var2);
    
        Iterable<T> findAllById(Iterable<ID> var1, Sort var2);
    
        Iterable<T> findAllById(Iterable<ID> var1, Sort var2, int var3);
    
        Page<T> findAll(Pageable var1);
    
        Page<T> findAll(Pageable var1, int var2);
    }

为了方便，我直接使用里面的save方法测试

创建Controller

@RestController
    @RequestMapping("/person")
    public class PersonController {
        @Autowired
        private PersonRepository personRepository;
    
        @RequestMapping("/addPerson")
        public Person addPerson() {
            Person person = new Person();
            person.setName("张三");
            person.setBorn(2018);
            return personRepository.save(person);
        }
    }
