https://developer.aliyun.com/profile/5yerqm5bn5yqg?spm=a2c6h.12873639.0.0.6eae304abcjaIB你仔细观察观察
没错吧这个，config是resource文件下，跟src同级有这个 welcome-servlet.xml文件不？
有的好久没看java了，
welcome-servlet.xml放置的路径不对，好像应该放在web-inf下面
你看看它编译出来是否在WEB-INF\classes目录下加一个
<mvc:default-servlet-handler/>
试试可以吗 osc居然有叫controller的，我要改一个RequestMapping的名字JDK和Spring的版本是多少？回复 @java种子选手:http://blog.csdn.net/sgls652709/article/details/49878741估计是版本问题，再检查下jdk1.6和1.8都试过，spring4.2 classpath*:config/ welcome-servlet.xml一般都是要配置两个配置文件的，你只配置了一个回复 @java种子选手:spring自己要一个，springmvc要一个，里面管理的bean作用域不一样的为何要两个？2020-06-09 16:01:56赞同 展开评论 打赏
