Spring 尝试将Json插入Neo4j

大家好，我是neo4j的新手，我正在尝试将Json输入neo4j，但我得到的是匹配语句，而不是创建语句。早些时候，我自己尝试了一些东西，当我插入Json消息时，只作为 {“姓名”：“约翰”，“系”：“科学”} 它没有出现故障，但每次我想要添加数字数据时，它都会出错

ID(n) as id, {type} as type","parameters":{"type":"node","rows":[{"nodeId":23,"props":{"name":"raj",
"dept":"science","age":11}}]},"resultDataContents":["row"],"includeStats":false}]}

这些是我的课 卡夫卡形象

@EnableKafka
@Configuration
public class KafkaConfiguration {

    @Bean
    public ConsumerFactory<String, Users> userConsumerFactory(){
        Map<String, Object> config = new HashMap<>();
         config.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "127.0.0.1:9092");
         config.put(ConsumerConfig.GROUP_ID_CONFIG, "group_json");
         config.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
         config.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, JsonDeserializer.class);
         return new DefaultKafkaConsumerFactory<>(config, new StringDeserializer(),
                    new JsonDeserializer<>(Users.class));
        }

    @Bean
    public ConcurrentKafkaListenerContainerFactory<String, Users> kafkaListenerContainerFactory() {
        ConcurrentKafkaListenerContainerFactory<String, Users> factory = new ConcurrentKafkaListenerContainerFactory<>();
        factory.setConsumerFactory(userConsumerFactory());
        return factory;
    }
}

Neo4J服务

@Service
public class Neo4jservice {

    @Autowired
    private UsersRepo userRepo;

    public UsersInfo saveIntoStudentsTable(UsersInfo users) {
        UsersInfo usern = userRepo.save(users);
        return (usern);
    }   

}

UsersRepo

@Repository
public interface UsersRepo extends Neo4jRepository<UsersInfo, Long>{

}

同样，UsersInfo类

@NodeEntity
public class Users {

    @Id
    private Long id;
    private String name;
    private String dept;
    private Integer age;

    **getters,setters and toString method here**
}

任何帮助都将不胜感激。谢谢

您正在设置

用户

类的

id

值。 这将使Spring数据Neo4j和用于持久化的Neo4j对象图映射器认为实体已经存在。

在这种情况下，它将

匹配现有
id（n）
上的
，并更新日志中显示的属性，而不是
创建一个新节点。
输入Json是什么意思？通常使用cypher create或merge语句或load CSV或Json加载数据。
public class Users {

    private Long id;
    private String name;
    private String dept;
    private Integer age;

    **getters,setters and toString method here**
}

@NodeEntity
public class Users {

    @Id
    private Long id;
    private String name;
    private String dept;
    private Integer age;

    **getters,setters and toString method here**
}
