先粘出我自己的pom代码：

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
