如何解决 mysql 与 logstash 的连接错误？

Google中的所有信息我都试过了。

然而，它继续失败，在堆栈溢出中留下问题。

请帮助我。

文件名：mysql.conf（logstash文件有相同的路径）

input {
    jdbc {
        clean_run => true
        jdbc_driver_library => "C:\ElasticSearch\mysql-connector-java-8.0.23\mysql-connector-java-8.0.23.jar"
        jdbc_driver_class => "com.mysql.jdbc.Driver"
        jdbc_connection_string => "jdbc:mysql://localhost:3306/jobschema", "root","1234"
        schedule => "* * * * *"
        statement => "select jobid, jobname, executiontime, jobstatus from logstashplugin WHERE jobid > :sql_last_value"
        use_column_value => true
        tracking_column => "jobid"
    }
}
output{
    elasticsearch {
        hosts => ["localhost:9200"]
        index => "logstashmysql"
    }
    stdout {
        codec => rubydebug
    }
}

如果您阅读错误消息，您会看到它说

:exception=>"LogStash::ConfigurationError", :message=>"Expected one of [ \t\r\n], \"#\", \"{\", \"}\" at line 6, column 74 (byte 282) after 
input {\n    
    jdbc {\n        
    clean_run => true\n        
    jdbc_driver_library => \"C:\ElasticSearch\mysql-connector-java-8.0.23\mysql-connector-java-8.0.23.jar\"\n
    jdbc_driver_class => \"com.mysql.jdbc.Driver\"\n
    jdbc_connection_string => \"jdbc:mysql://localhost:3306/jobschema\""

你的配置显示的是

    jdbc_connection_string => "jdbc:mysql://localhost:3306/jobschema", "root","1234"

我想你的意思是

jdbc_connection_string => "jdbc:mysql://localhost:3306/jobschema"
jdbc_user => "root"
jdbc_password => "1234"
