如何使用Kafka生产者来读取文件的内容？这里找到的典型解决方案（将文件通过|传递给生产者）看起来很脏而且很丑。
答案 0 :(得分：1)
我最近发现一个解决方案比将文件内容传递到生成器shell更合适，即使用FileSource Connector。
根据链接，FileSource Connector旨在准确解决＆＃34;将文件数据读入生产者＆＃34;的用例，例如检查日志文件的内容并在{{1}时启动警报遇到{或[ERROR]。
完整的命令是（假设我们在Kafka的根文件夹中）：
[FATAL]要配置的两个属性文件：
bin/connect-standalone.sh config/connect-standalone.properties config/connect-file-source.properties
config/connect-standalone.properties 第一个定义了如何连接到独立连接器。它就像：
config/connect-file-source.properties相当直截了当。只有两件事需要注意：

# The converters specify the format of data in Kafka and how to translate it into Connect data. Every Connect user will
# need to configure these based on the format they want their data in when loaded from or stored into Kafka

# The internal converter used for offsets and config data is configurable and must be specified, but most users will

# Set to a list of filesystem paths separated by commas (,) to enable class loading isolation for plugins
# (connectors, converters, transformations). The list should consist of top level directories that include
# any combination of:
# a) directories immediately containing jars with plugins and their dependencies
# b) uber-jars with plugins and their dependencies
# c) directories immediately containing the package directory structure of classes of plugins and their dependencies
# Note: symlinks will be followed to discover dependencies or plugins.
# Examples:
# plugin.path=/usr/local/share/java,/usr/local/share/kafka/plugins,/opt/connectors,
#plugin.path=
：Kafka引导程序服务器bootstrap.servers=localhost:9092：您必须将它们设置为(internal.)key/value.converter.schemas.enable=false以解析文件中的字符串行。第二个文件更简单：
falsename=local-file-source
connector.class=FileStreamSource
tasks.max=1
file=/tmp/test.txt
topic=connect-test
：要阅读的文件file：创建一个让消费者倾听的主题如果您想使用Storm消费内容，那就足够了。
如果要将Kafka中的内容写入文件，而不是读取文件，则使用FileSink Connector。我个人并没有使用它，但我想也是如此，但在消费者方面。配置文件为topic。
