问题：
为什么我得到这个错误没有找到HTTP请求与URI的映射
商同化
我试图将我的Springmvc项目转换为Spring启动。我根据Spring启动转换了所有必要的文件。控制台上没有错误。但是当我在浏览器中运行我的网络应用程序时，我得到了这个错误。
在名为“DispatcherServlet”的DispatcherServlet中找不到URI为[/onlineshopping/WEB-INF/views/page.jsp]的HTTP请求的映射
我尝试运行的任何url都会收到相同的错误，为什么？

您的视图解析器似乎没有用于处理JSP的viewclass。尝试在AppConfig中设置viewclass。JAVA
/** View resolver for JSP */
@Bean
public ViewResolver getViewResolver(){
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setViewClass(JstlView.class);
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".jsp");
return resolver;
}

添加此配置后，我的问题解决了
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
添加此配置后，白页错误停止，但jsp页面代码开始显示为html，因此添加了这两个依赖项。
