com.yucong.blog.title=Spring Boot Course
com.yucong.blog.desc=${com.yucong.blog.name} is learing ${com.yucong.blog.title}
# 随机字符串
com.yucong.blog.value=${random.value}
# 随机int
com.yucong.blog.number=${random.int}
# 随机long
com.yucong.blog.bignumber=${random.long}
# 10以内的随机数
com.yucong.blog.test1=${random.int(10)}
# 10-20的随机数
com.yucong.blog.test2=${random.int[10,20]}
# 多环境配置文件激活属性
