No Webapplicationcontext Found: No Contextloaderlistener Or Dispatcherservlet Registered?
No WebApplicationContext found: not in a DispatcherServlet request and no ContextLoaderListener registered?
在使maven构建SpringMVC 国际化(i18n) 项目中中出现页面显示异常，尝试查找了所有答案。一度怀疑是tomcat出了问题，但是经过测试得出tomcat是正常的，以下是项目的配置和运行异常。

-
翻译：没有发现WebApplicationContext:不是在DispatcherServlet请求中，也不存在已注册的ContextLoaderListener ? (是有道翻译)
-
web容器在加载web.xml的时候，初始化页面是web.xml配置中的login.jsp页面，login需要引用国际化(i18n)的文件并没有被WebApplicationContext加载。
-
解决思路：通过SpringmMVC 的 Controller视图跳转,来加载WebApplicationContext。然而该Context存在了，会自动加载国际化文件。
-
总结：初始化页面是，引用了未创建WebApplicationContext中的国际化文件,是不合法的，必须先创建好了Contxt容器了，才可以引用容器的资源。
- 笔者是编程小白，初次写博客还存在许多不足之处，希望能够得到批评和指正。
调试成功后的运行结果：
- 中文国际化
- 英文国际化
