修改一：先说父类依赖版本号，根据百度由2.0.1改为了1.5.6
修改二：再说导入jsp依赖的报错：Missing artifact org.apache.tomcat.embed:tomcat-embed-jasper:jar:8.5.16
如果不添加jsp依赖，就直接下载jsp文件，添加了就报错，现在我已经懵了。。。。
记录一下，有大神解答更是求之不得！！！
2019-10-10自己已经解决：
最后发现是版本的问题，从1.5.6测试到了2.0.3，发现2.0.3这个版本没有问题，证明了这个版本适合我的电脑和我的eclipse
操作系统：win10 64位
eclipse：Version: 2019-09 R (4.13.0)
maven应该是3.5.0
1、下面是jsp需要的依赖：
<!--servlet依赖begin -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<scope>provided</scope>
</dependency>
<!--servlet依赖end -->
<!--jsp标签库begin -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
<!--jsp标签库end -->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
2、接着是application.yml中添加前后缀
spring:
mvc:
view:
prefix: /WEB-INF/views
suffix: .jsp
