jdbc 相关问题

尝试连接到亚马逊红移驱动程序时出现“Caused by: java.lang.ClassNotFoundException: java.sql.SQLException”

下面是POM依赖 com.amazon.redshift redshift-jdbc42 下面是POM依赖 <dependency> <groupId>com.amazon.redshift</groupId> <artifactId>redshift-jdbc42</artifactId> <version>2.1.0.28</version> </dependency> 数据库连接代码包含在以下路径中 src -> main -> utils -> DatabaseConnection.java import java.sql.Driver; import java.util.Properties; import java.sql.*; public class DatabaseConnection { Logger logger = LoggerFactory.getLogger(DatabaseConnection.class); Connection connection = null; Properties props = new Properties(); public void getDataBaseConnection() { try { Class.forName("com.amazon.redshift.jdbc42.Driver"); logger.info("Connecting to database..."); String jdbcUrl = "jdbc:redshift://endpoint:port/dbname"; String dbUsername = "username"; String dbPassword = "password"; jdbcUrl = jdbcUrl + "?AccessKeyID=" + dbUsername + "&SecretAccessKey=" + dbPassword + "&DbUser=admin&ssl=true&tcpKeepAlive=true"; props.setProperty("ssl", "true"); props.setProperty("user", dbUsername); props.setProperty("password", dbPassword); connection = DriverManager.getConnection(jdbcUrl, props); if (connection != null) { logger.info("Connected to the database!"); } else { logger.info("Failed to make connection!"); } } catch (Exception e) { e.printStackTrace(); } } } 并在testng文件的以下路径中调用上面的代码 src->测试->java->测试->名称->sample_test.java import utils.DatabaseConnection; public class sample_test extends TestBase { DatabaseConnection dbconn = new DatabaseConnection(); @Test public void db_test(){ dbconn.getDataBaseConnection(); } } 执行上述操作后，出现以下错误 at java.lang.reflect.Method.invoke (Method.java:566) at org.codehaus.plexus.classworlds.launcher.Launcher.launchEnhanced (Launcher.java:283) at
