第二种
System.setProperty(“java.security.auth.login.config”, “/software/servers/maoxiangyi/kafka_client_jass.conf”); //配置文件路径
第三种
可以在程序启动参数中设置java.security.auth.login.config, 也就是启动参数加上-Djava.security.auth.login.config=/software/servers/maoxiangyi/kafka_client_jass.conf
java -jar -Djava.security.auth.login.config=/software/servers/maoxiangyi/kafka_client_jass.conf xxx.jar
