第一種
Properties props = new Properties();
props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, “node01:9092”);
props.put(“acks”, “all”);
props.put(“retries”, 0);
props.put(“batch.size”, 16384);

props.put(“sasl.jaas.config”,

第二種
System.setProperty(“java.security.auth.login.config”, “/software/servers/maoxiangyi/kafka_client_jass.conf”); //配置文件路徑
第三種
可以在程序啟動參數中設置java.security.auth.login.config, 也就是啟動參數加上-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
