在网上查看资料总结的原因大概是:windows系统中的用户名的属性也叫username,和外部配置文件中设置的username冲突,而
                                                       且控制台中显示的用户名称还是乱码,这是因为配置文件时gbk的缘故,所以在spring配置文件                                                         中使用${username}取值时,获取的是windows中的username的值,也就是我控制台中显乱码
                                                       部分,所以在连接数据库的时候用户名不正确获取不到连接
