以前运行好好的,不过现在怎么都运行不了,controller进不去,打开网页就是404,很郁闷,调试了十多天还是一样的,找不到问题

项目结构截图
你这边把controller给排除了,怎么可能访问到
这里不是应该用include吗,spring-mvc.xml,你自己exclude(排除)了Controller注解
http://localhost:8080/acp/
无法找到该网页
我记得 @Controller 这里需要映射路径的 @RequestMapping(value="/acp")
web-inf/view/index.jsp这个文件有吗???按照你的http://localhost:8080/acp/是跳转到这个页面的吧
试一下,如果,还不行,我在截图其它配置。
controller 下面的RequestMapping呢
你的配置是不是把controller给过滤掉了。。
