播放框架：使用security.protocol = SASL_SSL的Kafka连接由于错误而无法启动

时间：2019-11-14 05:54:42

标签： java ssl playframework apache-kafka

我想在向其中添加Kafka连接后启动Play应用，但是一旦我们将属性security.protocol设置为使用任何形式的SSL，它在启动期间都会失败。 SASL_SSL是我们的目标配置类型，我使用SASL_PLAINTEXT进行了测试，该应用程序加载得很好。这使我认为它可能找不到信任库？我将信任库放置在下面的属性文件中提到的位置。信任库的密码是在运行时通过env变量添加的，该密码显示在EventProducer.class文件中。事件产生器在运行时注入到另一个类中，正如我将security.protocol=SASL_PLAINTEXT设置为应用程序正常启动时提到的那样，但是security.protocol=SASL_SSL导致崩溃。这就是为什么我认为问题可能出在信任库的位置，但是我也将堆栈跟踪信息粘贴到了下面，因为我不确定是否出了问题。我尝试将信任库放置在应用程序/project_dir/trustore.jks的根目录下，并通过ssl.truststore.location=truststore.jks进行引用，但也失败了。也许我对应用程序如何引用文件的理​​解是不正确的，但会有所帮助。

    @Inject
    public EventProducer(ApplicationLifecycle lifecycle) {
        this.lifecycle = lifecycle;
        this.producer = initializeProducer();

        // add shutdown hook
        this.lifecycle.addStopHook(() -> {
            producer.close();
            return CompletableFuture.completedFuture(null);
        });
    }

    private KafkaProducer<String, String> initializeProducer() {
        Properties props = new Properties();

        try {

// Loads the props from the resource folder
props.load(EventProducer.class.getClassLoader().getResourceAsStream(String.format("kafka/%s", Config.KAFKA_PRODUCER_PROPERTIES)));

            // Adding extra config values for the SASL and SSL configs
            props.put("sasl.jaas.config", Config.KAFKA_SASL_JAAS_CONFIG);
            props.put("ssl.truststore.password", Config.KAFKA_SSL_TRUSTSTORE_PASSWORD);
        } catch (IOException e) {
            Logger.warn("Error reading Kafka producer properties file", e);
        }

        return new KafkaProducer<>(props);
    }
}
