学习spring boot 2.x时，使用jsp作为前端页面。在application.properties配置了jsp所在位置
spring.mvc.view.prefix:/WEB-INF/views/
spring.mvc.view.suffix:.jsp
启动spring boot时报错，找不到页面
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available
服务器端日志输出为：
o.s.w.s.r.ResourceHttpRequestHandler : Path with "WEB-INF" or "META-INF": [WEB-INF/views/home.jsp]
原因是spring boot默认不使用jsp，需要在pom中引用jsp的编译程序：
<!--jsp页面使用jstl标签 -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
<!--用于编译jsp -->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
