推荐答案
如果你想在spring boot中使用embedded tomcat，你必须改变你的依赖库tomcat-jasper 到 tomcat-embed-jasper.
If you want to use embedded tomcat in spring boot, you must change your dependency libriary tomcat-jasper to tomcat-embed-jasper.
spring-boot-starter-web中有spring-boot-starter-tomcat.你可以看到这里.
spring-boot-starter-tomcat中有tomcat-embed-core可以使用embedded tomcat.你可以看到这里.
There is tomcat-embed-core in spring-boot-starter-tomcat to use embedded tomcat. you can see here.
embed-jaspser 包含对 tomcat-embed-core 的依赖.你可以看到这里.
embed-jaspser which includes dependency with tomcat-embed-core. you can see here.
您使用的 tomcat-jasper 是不必要的，因为它不包含依赖项 tomcat-embed-core.您可以在此处查看.
The tomcat-jasper you used is unnecessary because it doesn't include with dependency tomcat-embed-core. you can see here.
