mysql - Logstash管道错误: error registering jdbc plugin

Question

当我第一次创建 Logstash jdbc conf 文件以将 MySQL 数据导入 Elasticsearch 时，它运行良好。但是，突然间，工作正常的相同文件不再工作，并给出错误“注册插件时出错”。

这是我的 sms-logstash.conf 文件

input {
  jdbc { 
    jdbc_connection_string => "jdbc:mysql://localhost:3306/sms"
    # The user we wish to execute our statement as
    jdbc_user => "root"
    jdbc_password => ""
    # The path to our downloaded jdbc driver
    jdbc_driver_library => "C:/Users/robesh/Downloads/logstash-6.2.3/logstash-6.2.3/bin/mysql-connector-java-5.1.45-bin.jar"
    jdbc_driver_class => "com.mysql.jdbc.Driver"
    # our query
    statement => "SELECT * FROM salon_reg" 

    }
  }

output {
  stdout { codec => rubydebug }

  elasticsearch {
  "hosts" => "localhost:9200"
  "index" => "sms"
  "document_type" => "salon_reg"


  }


}  

当我运行此命令时 bin/logstash -f sms-logstash.conf

出现以下错误

有趣的是，同一个文件以前工作正常，并且很好地将我的数据索引到 Elasticsearch，但现在突然出现错误。

可能是编码问题，请确保logstash文件有UTF-8编码。
