使用 hikaricp 的 Oracle 数据库连接 java
Oracle db connection using hikaricp java
我正在尝试使用 hikaricp 和 java..
为 Oracle 数据库创建连接池
下面是我的代码..
public class OracleCon {
public static void main(String[] args) {
try {
Connection con = dataSource().getConnection();
Statement stmt = con.createStatement();
} catch (Exception e) {
System.out.println(e);
}
}
private static DataSource dataSource() {
final HikariDataSource ds = new HikariDataSource();
ds.setMaximumPoolSize(100);
ds.setDataSourceClassName("oracle.jdbc.driver.OracleDriver");
ds.addDataSourceProperty("serverName", "localhost");
ds.addDataSourceProperty("port", "5432");
ds.addDataSourceProperty("databaseName", "test");
ds.addDataSourceProperty("user", "user");
ds.addDataSourceProperty("password", "password");
return ds;
}
}
我遇到了以下错误。

任何建议也会有所帮助..谢谢..
在 dataSource()
方法中,您试图将 驱动程序 class 分配给 数据源 class 属性。不要使用 setDataSourceClassName()
,而是使用 setDriverClassName()
方法。
您的最终配置如下所示 -
private static DataSource dataSource() {
final HikariDataSource ds = new HikariDataSource();
ds.setMaximumPoolSize(100);
ds.setDriverClassName("oracle.jdbc.driver.OracleDriver");
ds.addDataSourceProperty("serverName", "localhost");
ds.addDataSourceProperty("port", "5432");
ds.addDataSourceProperty("databaseName", "test");
ds.addDataSourceProperty("user", "user");
ds.addDataSourceProperty("password", "password");
return ds;
}
