我正在使用 dfc.properties，任何人都可以帮助我上述错误的原因是什么
我的 dfc.properties 文件是
dfc.data.dir=./dfc
dfc.registry.mode=file
dfc.search.ecis.enable=false
dfc.search.ecis.host=
dfc.search.ecis.port=
dfc.tokenstorage.dir=./dfc/apptoken
dfc.tokenstorage.enable=false
dfc.docbroker.host[0]=random host_name
dfc.docbroker.port[0]=1489
#Additions 3/22
dfc.security.keystore.file=./dfc/dfc.keystore
dfc.session.secure_connect_default=try_native_first
dfc.globalregistry.repository[0]=random docbase
dfc.globalregistry.username=username
dfc.globalregistry.password=password
#dfc.cache.object.size=100
#dfc.session.pool.expiration_interval=10
dfc.properties 中的任何值是否导致上述错误？请帮我
