修改驱动源码后需要重新编译构建，由于mysql编译需要两个jdk版本且还需要hibernate4和junit，这里记录下。

• 安装ant。
• 配置两个jdk，5和8。并修改build.xml配置，如下：

    <property name="com.mysql.jdbc.jdk5" value="/usr/java/jdk1.5.0_15" />
    <property name="com.mysql.jdbc.jdk8" value="/home/vagrant/java/jdk1.8.0_73" />

• 上传hibernate4必须包到src/lib/hibernate4/下。
• 上传junit包到src/lib/下。
• 可能会出现如下报错，这个是jdk的bug，用的jdk版本是jdk-1_5_0_15，需要使用jdk1.5.0_22。
