Spring boot应用程序中的Spring Kafka SSL设置

Question

我正在尝试用Kafka客户端设置一个Spring Boot应用程序以使用SSL。我有我的密钥库。jks和信任库。jk存储在文件系统（docker容器上）上，因为：https://github.com/spring-projects/spring-kafka/issues/710

以下是我的application.yml：

spring:
  kafka:
      ssl:
        key-password: pass
        keystore-location: /tmp/kafka.client.keystore.jks
        keystore-password: pass
        truststore-location: /tmp/kafka.client.truststore.jks
        truststore-password: pass

但是当我启动应用程序(在docker容器中)时，它说:

Caused by: java.lang.IllegalStateException: Resource 'class path resource [tmp/kafka.client.keystore.jks]' must be on a file system
[..]
Caused by: java.io.FileNotFoundException: class path resource [tmp/kafka.client.keystore.jks] cannot be resolved to URL because it does not exist

我检查了容器，.jks在 /tmp 中。

我不明白如何通过。jks到Spring靴。

更新06/07/2018

这是我的dockerfile

FROM openjdk:8-jdk-alpine
VOLUME /tmp
COPY ssl/kafka.client.keystore.jks /tmp
COPY ssl/kafka.client.truststore.jks /tmp
ARG JAR_FILE
ADD ${JAR_FILE} app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

根据讨论并启用 kafka ssl 配置，首先需要在消费者工厂中启用和设置 ssl 属性

@Bean
public ConsumerFactory<String, ReportingTask> consumerFactory() {
    Map<String, Object> props = new HashMap<>();
    props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
    props.put(ConsumerConfig.GROUP_ID_CONFIG, groupId);
    props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
    props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, JsonSerializable.class);
    props.put(ConsumerConfig.CLIENT_ID_CONFIG, clientId);
    props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, enableAutoCommit);
    props.put(ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG, autoCommitInterval);
    props.put(ConsumerConfig.SESSION_TIMEOUT_MS_CONFIG, sessionTimeout);
    props.put(ConsumerConfig.MAX_POLL_RECORDS_CONFIG, maxRecords);
    props.put(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, offSet);
    if (sslEnabled) {
        props.put("security.protocol", "SSL");
        props.put("ssl.truststore.location", trustStoreLocation);
        props.put("ssl.truststore.password", trustStorePassword);

        props.put("ssl.key.password", keyStorePassword);
        props.put("ssl.keystore.password", keyStorePassword);
        props.put("ssl.keystore.location", keyStoreLocation);
    }
    return new DefaultKafkaConsumerFactory<>(props, new StringDeserializer(), new JsonDeserializer<>(Task.class));
}

并将证书复制到docker容器中

COPY ssl/stage/* /var/lib/kafka/stage/

如果有人还在看这个，请尝试在file：//之前添加文件路径：

truststorelocation: "file:///tmp/kafka.client.keystore.jks"

错误是抱怨缺少URL-添加协议（file://）使路径成为URL（基本上来说）
