我正在开发简单的Spring Boot MVC应用程序。以前我只使用了Spring + Hibernate（也就是servlet.xml等），我试图重建项目以使用Spring Boot。虽然我已阅读了很多答案，但我仍然无法修复Spring Boot找不到我的.jsp文件 - 它显示白标签错误页面。
关于SO的很多答案都包括tomcat-embed-jasper和jstl在pom.xml但我已经拥有它。我正在使用IntelliJ IDEA 17 Ultimate，Tomcat 8.5.13，最新版本的Spring和Spring Boot。Spring Boot jsp文件无法找到

你在哪里添加bean viewResolver –
我想我没有什么像viewResolver在我的项目中，我既没有XML文件也没有任何配置类 – Colonder
看到我的答案，你的基本问题是不使用预期的Maven项目布局。 –
