Spring boot application.yml 中的 Spring Kafka SSL 设置

Question

我正在尝试使用 Kafka 客户端设置 Spring Boot 应用程序以使用 SSL。因此，我将 keystore.jks 和 truststore.jks 存储在文件系统（在 docker 容器上）中：https : //github.com/spring-projects/spring-kafka/issues/710

这是我的 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。

我无法理解如何将 .jks 传递给 Spring Boot。

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"]

Answer 1

如果有人仍在查看此内容，请尝试在文件路径前添加 file://：

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）

根据讨论和启用kafka ssl配置，首先需要在consumerFactory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/
