springmvc报404错误No mapping found for HTTP request with URI [/mavenSpringmvc/requesttest] in DispatcherServlet with name 'spring'

问题404错误的原因有很多种

有这种，后边不带url的

springmvc报404错误No mapping found for HTTP request with URI [/mavenSpringmvc/requesttest] in DispatcherServlet with name 'spring'-LMLPHP

这种一般就是没有进入到controller中

可以在toncat中看到信息

十一月 12, 2018 12:21:25 下午 org.springframework.web.servlet.DispatcherServlet noHandlerFound
警告: No mapping found for HTTP request with URI [/mavenSpringmvc/requesttest] in DispatcherServlet with name 'spring'

查看controller

springmvc报404错误No mapping found for HTTP request with URI [/mavenSpringmvc/requesttest] in DispatcherServlet with name 'spring'-LMLPHP

请求确实无法匹配

修改为

springmvc报404错误No mapping found for HTTP request with URI [/mavenSpringmvc/requesttest] in DispatcherServlet with name 'spring'-LMLPHP

问题解决
