spring boot 2.x Path with "WEB-INF" or "META-INF"

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>
