前后端分离 SSM 统一异常处理 解决404不被拦截的问题
优点就不再啰嗦了...................
感谢@书呆子Rico，
这位博主在spring-mvc.xml文件中设置了
导致spring对404的错误码不能拦截。
代码撸起来吧..........................
统一返回文件

}
}有web.xml配置文件的SSM架构实现如下：
spring
org.springframework.web.servlet.DispatcherServlet
throwExceptionIfNoHandlerFound
true
contextConfigLocation
classpath:config/spring-mvc.xml
1
因为 DispatcherServlet源码中对于 throwExceptionIfNoHandlerFound 默认是 false 我们需要在初始化DispatcherServlet时将参数值更改为true.
spring-mvc.xml
所以一定要注释调此处
