Do you really have spaces on each side of the slash?

Also, are you sure the jdbc-mysql gem is available in your Logstash installation?

By mistake I write it with spaces  
Part of my code in logstash:

input {  
udp {  
port =\> 5965  
codec =\> plain { charset =\> "UTF-8" }  
type =\> "TextEvent"  
}  
}

filter {  
if [type] == "TextEvent" {  
ruby {  
code =\> "  
require 'rubygems'  
require 'java'  
require 'base64'  
require 'openssl'  
require 'inifile'  
require 'jdbc/mysql'

when reviewing the log it appears:  
[2018-07-16T07:58:38,242][ERROR][logstash.filters.ruby] Ruby exception occurred: no such file to load -- jdbc/mysql
