我在尝试使用neo4j bolt驱动程序运行简单的密码时遇到错误.什么出了什么问题？
public void boltDriver() {
Config noSSL = Config.build()
.withEncryptionLevel(Config.EncryptionLevel.NONE).toConfig();
Driver driver = GraphDatabase.driver("bolt://localhost:7474",
AuthTokens.basic("neo4j", "neo4j1"), noSSL); // <password>
try (Session session = driver.session()) {
StatementResult result;
String foafQuery = " MATCH (n) WHERE EXISTS(n.country) RETURN DISTINCT \"node\" as element, n.country AS country ";
result = session.run(foafQuery, parameters("name", "Joe"));
while (result.hasNext()) {
Record next = result.next();
System.out.println(next.get("element"));
System.out.println(next.get("country"));
}
}
}
