Answer 4

 No matching handler method found for servlet request: path '/login.xhtml....
没有找到映射方法，原因可能有下列：
1、jsp页面定义的方法与controller中注解方法不一致，如jsp中form定义get则：
注解 @RequestMapping(value = '/login.xhtml", method = RequestMethod.GET )如是POST则：method = RequestMethod.POST
2、没有把controller类所在的包进行扫描：
3、映射路径写的有问题
