我想使用JDBC SQL Server作为输入使用Logstash在ElasticSearch中导入数据，我尝试应用此help page 我有感觉wat是预期但logstash抛出一个错误告诉我它无法连接到我的源数据库
input {
jdbc {
jdbc_driver_library => "C:\logstash-5.1.1\driver\sqljdbc_6.0\enu\sqljdbc42.jar"
jdbc_driver_class => "com.microsoft.sqlserver.jdbc.SQLServerDriver"
jdbc_connection_string => "jdbc:sqlserver://(LocalDb)\MSSQLLocalDB;databaseName=testDB;Integrated Security=true"
jdbc_user => "myUsername"
#jdbc_password => "YOUR DATABASE PASSWORD, IF YOU DONT HAVE ONE REMOVE jdbc_password"
statement => " select * from CUSTOMERS "
}
}
output {
stdout { codec => json_lines }
}
它给我写了一个错误：

简短翻译：它首先告诉我与数据源的连接失败
你知道为什么会这样吗？
