import org.neo4j.driver.AuthTokens;

import org.neo4j.driver.GraphDatabase;
import org.neo4j.driver.Session;

public class Neo4jExample {
    public static void main(String[] args) {
        // 连接Neo4j服务器
        Driver driver = GraphDatabase.driver("bolt://localhost:7687", AuthTokens.basic("username", "password"));
        
        // 获取Session
        try (Session session = driver.session()) {
            // 执行Cypher查询等操作
            // ...
        }
        
        // 关闭连接
        driver.close();
    }
