【java】解析jaas.conf小demo

kafka-jaas.conf

KafkaClient {
  com.sun.security.auth.module.Krb5LoginModule required
  useKeyTab=true
  useTicketCache=false
  keyTab="config/user.keytab"
  principal="user@XXXXX.COM"
  serviceName="kafka";
};

scala语言：

import sun.security.provider.ConfigFile
import java.net.{URI, URL}

    val spi = new ConfigFile.Spi(new URI("file:///D:///tmp/kafka-jaas.conf"))
    val opts = spi.engineGetAppConfigurationEntry("KafkaClient").head.getOptions
    val principal: String = opts.get("principal").toString
    val keytab: String = opts.get("keyTab").toString
    println(principal, keytab)

其他的field直接在map里边获取就好了。
