由于使用jsp运行我的Spring Boot App，我最终得到了这个日志。

If your application is running on WebSphere Application Server you may
be able to resolve this problem by setting
com.ibm.ws.webcontainer.invokeFlushAfterService to false
很明显，在Spring Boot中，不需要手动配置。那么，我该如何解决这个错误？
我无法解决如何解决问题。我在application.properties中配置了jsp解析器。
spring.mvc.view.prefix=/WEB-INF/view/
spring.mvc.view.suffix=.jsp
我在pom.xml中有tomcat-embedded-jasper。
