jboss给出org.apache.kafka.common.kafkaexception:无法读取auth.conf

当我在wildflyv10中部署我的简单kafka项目的war（它可以很好地作为一个jar工作）时，我得到了一些zookeeper连接异常[1]

错误是由Kafka中的以下代码引起的

String loginConfigFile = System.getProperty(JAVA_LOGIN_CONFIG_PARAM);
if (loginConfigFile != null && loginConfigFile.length() > 0) {
        File configFile = new File(loginConfigFile);
        if (!configFile.canRead()) {
            throw new KafkaException("File " + loginConfigFile + "cannot be read.");
        }
...

在wildfly 10中，javax\u login\u config param的属性( java.security.auth.login.config )设置为 jar:file:/opt/jboss/wildfly/modules/system/layers/base/org/picketbox/main/picketbox-4.9.4.Final.jar!/auth.conf .
在wildfly 9中，上述属性为空。因此，快速解决方法是通过将该属性设置为null来模拟wildfly 9。
为此，请使用 -Djava.security.auth.login.config= 选项，即空值。我的standalone.conf如下所示：

if [ "x$JAVA_OPTS" = "x" ]; then
    JAVA_OPTS="-Xms2048m -Xmx2048m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m -Djava.net.preferIPv4Stack=true"
    JAVA_OPTS="$JAVA_OPTS -Djboss.modules.system.pkgs=$JBOSS_MODULES_SYSTEM_PKGS -Djava.awt.headless=true -Djava.security.auth.login.config="
else
    echo "JAVA_OPTS already set in environment; overriding default settings with values: $JAVA_OPTS"
fi
