mosquitto本机测试，启动客户端无法收到之前订阅过的消息

[CrossroadW]

测试步骤:
客户端启动，订阅了topic，关闭程序
命令行发布topic
再次启动客户端，并没有收到之前订阅过的消息，与预期不符

排除是重新生成clientid导致的可能性，这几次都是同一个clientid

windows 才有此问题，且测试即使修改了 mosquitto.conf 配置文件，开启了持久化

# =================================================================
# Persistence
# =================================================================

# If persistence is enabled, save the in-memory database to disk
# every autosave_interval seconds. If set to 0, the persistence
# database will only be written when mosquitto exits. See also
# autosave_on_changes.
# Note that writing of the persistence database can be forced by
# sending mosquitto a SIGUSR1 signal.
autosave_interval 1800

# If true, mosquitto will count the number of subscription changes, retained
# messages received and queued messages and if the total exceeds
# autosave_interval then the in-memory database will be saved to disk.
# If false, mosquitto will save the in-memory database to disk by treating
# autosave_interval as a time in seconds.
autosave_on_changes true

# Save persistent message data to disk (true/false).
# This saves information about all messages, including
# subscriptions, currently in-flight messages and retained
# messages.
# retained_persistence is a synonym for this option.
persistence true

# The filename to use for the persistent database, not including
# the path.
persistence_file mosquitto.db

# Location for persistent database.
# Default is an empty string (current directory).
# Set to e.g. /var/lib/mosquitto if running as a proper service on Linux or
# similar.
persistence_location D:\\mosquitto\\data\\

依然无效，测试管理员模式运行也无效。
