Spring的scheme有问题：
1.缺少scheme，需要添加上对应的scheme
2.scheme版本不对，在你所使用的spring发行包中，去找xsd文件，看它的版本是什么(可能会有多个，只要对应上一个就行)，看是否对应的上。
我这次的错误情况数据第二种，报错时候的scheme如下：
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.1.xsd"需要改为，因为在org.springframework.context.config中有spring-context-2.5.xsd、spring-context-3.0.xsd、spring-context-3.1.xsd，并没有4.1：
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd"

1.用户名、密码错误，仔细再输入，或者数据库的连接有问题，如没有连接权限，等等
2.数据库有SSL加密，需要在spring配置文件中，把加密设置为false。（该错误在控制台的报错信息中会有sslException字样，我的并没有）
3.问题出在tomcat的webapps下面的生成的项目太多了，而且我的所有项目的配置文件名都一样的。。。。（我的就是这个原因）
解决方法：我怀疑我的问题就是这个，所以我把server.xml中的<Context docBase="SSM" path="/SSM" reloadable="true" source="org.eclipse.jst.jee.server:SSM"/>删除，然后把项目从新添加到tomcat中，重启，就好了)
