将spring从3.1升级到3.2启动tomcat出现如上错误：
仔细检查过web.xml中关于spring配置引入，spring-mvc配置引入都没有问题，以及spring配置文件读取方式，都是对的
引入spring jar包换回成3.1又没有问题，换成3.2又不行，查看编译环境用的是1.8，将1.8降为1.7，问题解决，服务启动正常,
也就是说spring 3.2不支持1.8编译环境，解决办法就是降为1.7编译环境
spring官网说了，要使用java8，只支持spring 4.X以上版本，而spring的使用最低java要求java5及以上，
如果出现例外，那就例外说了，比如一开始spring 3.1就可以在java8上编译。
