上述文件为web.xml

此为项目配置文件

![项目配置文件][70]

出错原因：

仔细核查后发现是servlet标签下springmvc的解析地址写错了

将classpath:spring/springmvc,xml写成了classpath:spring/spring-\*,xml

导致项目无法解析视图。

修改的地方：

修改 classpath:spring/spring-\*,xml改为classpath:spring/springmvc,xml

再将context-param标签下的param-value中的值

classpath:spring/spring-security.xml改为classpath:spring/spring-\*,xml

更改后，项目就正常了
