我正在尝试在我的 Spring 应用程序中使用 PGJDBC-NG 驱动程序进行 Postgress JDBC 连接。

@Bean
@Qualifier("dataSource1")
public DataSource getDataSource1() {

    PGDataSource dataSource = new PGDataSource();

    // anmol :Removed VCAP_SERVICES and Changes has done according to docker
    try {
        
        dataSource.setUser(env.getRequiredProperty(PROPERTY_BLUEMIX_DEMO_NAME_POSTGRESQL_DATABASE_USERNAME).trim());
        dataSource.setPassword(env.getRequiredProperty(PROPERTY_BLUEMIX_DEMO_NAME_POSTGRESQL_DATABASE_PASSWORD).trim());
        dataSource.setDataSourceName("com.impossibl.postgres.jdbc.PGDataSource");
        dataSource.setDatabaseUrl("jdbc:pgsql://localhost:5432/test");
        dataSource.setRegistrySharing(true);
        dataSource.setApplicationName("com.impossibl.postgres.jdbc.PGDriver");
        dataSource.setSslMode("verify-full");
        dataSource.setSslCertificateFile("postgresql.crt");
        dataSource.setSslCaCertificateFile("root.crt");
        dataSource.setSslKeyFile("postgresql.pk8");
        dataSource.setSslKeyPassword("None");
        dataSource.setSslKeyPasswordCallback("com.impossibl.postgres.protocol.ssl.ConsolePasswordCallbackHandler");
        dataSource.setSslHomeDir(".postgresql");

    }catch (Exception e) {
        e.printStackTrace();
    }
    return dataSource;
}

但是在运行时给出错误...
