先粘出我自己的pom代碼：

修改一：先說父類依賴版本號，根據百度由2.0.1改為了1.5.6
修改二：再說導入jsp依賴的報錯：Missing artifact org.apache.tomcat.embed:tomcat-embed-jasper:jar:8.5.16
如果不添加jsp依賴，就直接下載jsp文件，添加了就報錯，現在我已經懵了。。。。
記錄一下，有大神解答更是求之不得！！！
2019-10-10自己已經解決：
最后發現是版本的問題，從1.5.6測試到了2.0.3，發現2.0.3這個版本沒有問題，證明了這個版本適合我的電腦和我的eclipse
操作系統：win10 64位
eclipse：Version: 2019-09 R (4.13.0)
maven應該是3.5.0
1、下面是jsp需要的依賴：
<!--servlet依賴begin --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <scope>provided</scope> </dependency> <!--servlet依賴end --> <!--jsp標簽庫begin --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!--jsp標簽庫end --> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> <scope>provided</scope> </dependency>
2、接着是application.yml中添加前后綴
spring:
mvc:
view:
prefix: /WEB-INF/views
suffix: .jsp
