有没有人在从 Logstash JDBC 输入插件连接到 Oracle 数据库时遇到这个问题：

我能够通过 SQL 开发人员使用相同的凭据和连接详细信息进行连接。

这是我的 Logstash JDBC 输入：

jdbc { 
    jdbc_connection_string => "jdbc:oracle:thin:@<ORACLE_HOST>:<ORACLE_PORT>:<ORACLE_SID>"
    jdbc_user => "<USER>"
    jdbc_password => "<PASSWORD>"
    jdbc_driver_library => "<PATH>/lib/ojdbc8-21.1.0.0.jar"
    jdbc_driver_class => "Java::oracle.jdbc.driver.OracleDriver"
    jdbc_paging_enabled => true
    connection_retry_attempts => 5
    connection_retry_attempts_wait_time => 10
    statement=> "select<Fields> from <Table>"
    type => "<Temp Val>"
  }

我的 Oracle 版本是 19.3 和 Logstash-7.9.1 (windows)

【解决方案1】：

我看到您正在使用 oracle jdbc 驱动程序 21.1 版本中的 ojdbc8.jar。尝试一个简单的独立 java 测试来连接你的数据库，看看你是否得到同样的错误。如果问题重现，则粘贴完整的错误堆栈跟踪。 SQLDeveloper 可能正在使用不同版本的 ojdbc jar。
