JDBCTHINURL中的hibernatereactive发生错误

在 Hibernate Reactive 中使用 JDBC THIN Driver 时，需要对 JDBC 连接 URL 进行特殊处理。以下是一份示例代码：

import io.r2dbc.spi.ConnectionFactories;
import io.r2dbc.spi.ConnectionFactory;
import org.hibernate.reactive.pool.impl.PoolConfiguration;
import org.hibernate.reactive.provider.Settings;
import org.hibernate.reactive.provider.jdbc.JdbcResourceLocalTransactionCoordinatorBuilderImpl;
import org.hibernate.reactive.provider.jdbc.JdbcService;
import org.hibernate.reactive.provider.jdbc.JdbcServiceImpl;

import java.util.Properties;

public class CustomJdbcService extends JdbcServiceImpl {

  @Override
  protected Settings.SettingsBuilder<?, ?> configureSettings(Settings.SettingsBuilder<?, ?> settingsBuilder, Properties properties) {
    // 添加 url 参数：
    // - 将协议头替换为 jdbc:oracle:thin
    // - 将端口号后面的 uri 编码部分替换为 connectString 参数的值
    final String url = properties.getProperty("hibernate.connection.url");
    if (url == null) {
      throw new IllegalArgumentException("hibernate.connection.url not specified");
    }
    final String[] urlParts = url.split(":");
    String newUrl = "jdbc:oracle:thin:@" + properties.getProperty("connectString", "") +
            (urlParts.length > 3 ? ":" + urlParts[3] : "") +
            (urlParts.length > 4 ? ":" + urlParts[4] : "");
    settingsBuilder.applyJdbcUrl(newUrl);

    // 进行正常的 Hibernate Reactive 配置：
    return super.configureSettings(settingsBuilder, properties);
  }

  @Override
  public JdbcResourceLocalTransactionCoordinatorBuilderImpl getTransactionCoordinatorBuilder() {
    return new JdbcResourceLocalTransactionCoordinatorBuilderImpl(null) {
      @Override
      protected ConnectionFactory createConnectionFactory(PoolConfiguration configuration) {
        // 建立 R2DBC 的连接工厂并转换为 JDBC 连接工厂
        ConnectionFactory r2dbcConnectionFactory = ConnectionFactories.get(configuration.getUrl());
        return new ReactiveJdbcConnectionFactory(
          new io.r2dbc.spi.ConnectionFactory() {
            @Override
            public Connection create() { return r2dbcConnectionFactory.create().block
