Spring 控制器未分派请求的视图
我是春天的新手。运行程序后,我收到如下错误 -名为“dispatcher”的DispatcherServlet正在处理[/SpringLoginApp/save]的POST请求 -请求[/save]的匹配模式为[/**] -请求[/save]的URI模板变量为{} -使用handler-[org.springframework.web.servlet.resource将[/save]映射到HandlerExecutionChain。DefaultServletHttpRequestHandler@5771b5fa] 和1个拦截器-跳过CORS处理:请求来自同一来源 -返回给名为“dispatcher”的DispatcherServlet的Null ModelAndView:-假设HandlerAdapter已完成请求处理 -已成功完成请求 这是我要指挥的控制器Spring 控制器未分派请求的视图,spring,Spring,我是春天的新手。运行程序后,我收到如下错误 -名为“dispatcher”的DispatcherServlet正在处理[/SpringLoginApp/save]的POST请求 -请求[/save]的匹配模式为[/**] -请求[/save]的URI模板变量为{} -使用handler-[org.springframework.web.servlet.resource将[/save]映射到HandlerExecutionChain。DefaultServletHttpRequestHandler

员工服务。添加员工(员工);
返回“重定向:/add”;
}

公共模型和视图addEmployee(@ModelAttribute(“命令”)EmployeeBean EmployeeBean,BindingResult)

如果我错了,请原谅。。。有什么帮助吗?没有错误,只是调试信息。@M.Deinum…是的。但我想问一下为什么返回空视图…而不返回匹配模式…尽管它在控制器中…请帮助没有匹配模式(这就是消息告诉您的)。。。如上所述,它只是信息/调试/跟踪日志记录。关于模型,它是一个没有模型的重定向。
