使用场景
某些网页有反扒机制,使用jsoup和httpclient不能满足要求,使用selenium可以。
环境配置
https://registry.npmmirror.com/binary.html?path=chromedriver/
下载解压即可,解压路径代码中会使用到。

数据库设置
db.setting放入到resources里边
## db.setting文件
url = jdbc:mysql://xxxxxx:3306/tiantian_fund?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
user = root
pass = xxxxxxx
## 可选配置
# 是否在日志中显示执行的SQL
showSql = true
# 是否格式化显示的SQL
formatSql = false
# 是否显示SQL参数
showParams = true
# 打印SQL的日志等级,默认debug,可以是info、warn、error
sqlLevel = debug
