# The entropy gathering device can also be specified with the System
# property "java.security.egd". For example:
#
#   % java -Djava.security.egd=file:/dev/random MainClass
#
# Specifying this System property will override the
# "securerandom.source" Security property.
#
# In addition, if "file:/dev/random" or "file:/dev/urandom" is
# specified, the "NativePRNG" implementation will be more preferred than
# SHA1PRNG in the Sun provider.
#
#securerandom.source=file:/dev/random

securerandom.source=file:/dev/./urandom

注释 securerandom.source=file:/dev/random  添加一行 securerandom.source=file:/dev/./urandom
