我有elasticsearch和Kibana是启动和运行，我想使用logstash读取日志，所以我已经通过csv文件作为输入在logstash.conf文件，但它不阅读日志和自动关闭。
这是我运行logstash命令的方式：

D:\logstash-8.1.0\bin>logstash -f "D:/logstash.conf"

日志存储.conf

input{
 file{
   path => "D:/unicorn.csv"
   start_position => beginning
 }
}
output{
  elasticsearch{
    hosts => "localhost:9200"
    index => "indexforlogstash"
}
stdout{}
}

下面是终端输出：

you have compelling reasons for using your own JDK (organizational-specific compliance 
requirements, for example), you can configure LS_JAVA_HOME to use that version instead.
