我正在尝试连接PostgreSQL数据库Logstash以将数据postgres从elasticsearch. 我正在使用 JDBC 驱动程序来Logstash连接postgres.

但我收到以下错误

[2019-06-27T13:04:05,943][ERROR][logstash.javapipeline] 插件出现不可恢复的错误。将重新启动此插件。

我的配置是

  • Java 版本 - “1.8.0_211”
  • postgres (PostgreSQL) 11.0
  • logstash-7.2.0

这是我的logstash conf文件

input {
    jdbc{
        #input configuration
        jdbc_driver_library => "postgresql-42.2.6.jar"
        jdbc_driver_class => "org.postgresql.Driver"
        jdbc_connection_string => "jdbc:postgresql://localhost:5432/LogstashTest"
        jdbc_user => "postgres"
        jdbc_password => "root"
        statement => 'SELECT  * FROM public."contacts";'
    }
}
output{
    stdout { codec => json_lines }
}

当您将不正确的配置文件传递给 Logstash 时，由于 PostgreSQL JDBC 驱动程序损坏，可能会出现此问题。我有同样的问题，你需要检查你的 JDBC 驱动程序文件。
