上面是访问mvc后出现的报错信息
网上对于这段异常的解释最为接近的是：jar的冲突 。
我得到解决突破的最后一个查阅：

| 3 down vote | Any time I get those kinds of Method Not Found exceptions inside frameworks (especially mature ones) the first thing I do is to look for conflicting dependencies. Sometimes two different libraries include different versions of the same dependency which, in my experience, commonly causes this type of issue. |
| up vote 3 down vote | Your Servlet has a Spring 3 dependency (where the ResourceEditor(ResourceLoader,PropertyResolver) constructor is present) but you use a Spring 2 library where no such constructor is available! |
然后我开始检查自己的依赖管理和最终target下lib中的jar包：
发现如图：
target的lib目录中也有此jar包。
我首先把这个spring:2.5.6SEC03.jar 从lib中删除，
再次启动项目访问， ok，O(∩_∩)O 可以正常访问了。
然后分析为什么会突然多了这么个东西：
查看依赖管理，如上图，其他我的pom文件中是没有此依赖添加的。
那么就只可能是此module本身创建是的环境里就带上了这么个东西，所以我查看项目构建环境
打开 file > project structure: （这个地带jar包的截图我之前查找问题时复制的工程里截的，上面那个工程我已经解决）
崩溃。。。
说明项目构建这一块还是太嫩了。。
勾选然后删除，点击应用即可！
