最近出bug出的太勤了，再来一条

关于配置spring中dbcp2时错误java.lang.AbstractMethodError: com.mysql.jdbc.Connection.isValid(I)Z的解决

只需要在jdbc.properties里面另外加一个

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test
jdbc.username=root
jdbc.password=a
jdbc.validationQuery=select 1

然后再在beans.xml配置文件里:
