Camunda服务器正在启动，无法启动jdbc连接（oracle DB）

Question

我有一个到oracle DB的jdbc连接；

if(connection == null || connection.isClosed()) {
    try {
        connection = null;
        connection = DriverManager.getConnection("jdbc:oracle:thin:@//localhost:1521/ORCL", "usr", "pass");
} catch(Exception e) {
    e.printStackTrace();
    throw e;
}

谢谢！

问题解决了！

您首先需要通过反射获得jdbc驱动程序类，当我启动SpringBoot应用程序时，Spring会自动创建类

  if(connection == null || connection.isClosed()) {
        try {
            connection = null;
            Class.forName("oracle.jdbc.driver.OracleDriver");
            connection = DriverManager.getConnection("jdbc:oracle:thin:@//localhost:1521/ORCL","usr","pass");
        }
        catch(Exception e) {
            e.printStackTrace();
            throw e;
        }
    }
    return connection;
