Whitelabel 错误页面而不是特定的 jsp 页面

Question

我已经看到了几个关于这个问题的问题，但我还没有解决这个问题：

我已经检查过它们：

Springboot Whitelabel Error Page --- 我的控制器被spring找到并注册了。

Spring boot - Whitelabel 错误页面--- 我的控制器带有注释，@Controller并且我返回与我想查看的 jsp 文件名匹配的字符串。

这是我的pom.xml文件：

<?xml version="1.0" encoding="UTF-8"?>

        </plugins>

</project>

这是application.properties文件：

server.port=8088

spring.mvc.view.prefix=/WEB-INF/views/

spring.mvc.view.suffix=.jsp

这是文件夹结构：

您需要在您的 pom 中添加以下依赖项&nbsp; &nbsp; <dependency>&nbsp; &nbsp; &nbsp; &nbsp; <groupId>org.springframework.boot</groupId>&nbsp; &nbsp; &nbsp; &nbsp; <artifactId>spring-boot-starter-tomcat</artifactId>&nbsp; &nbsp; &nbsp; &nbsp; <scope>provided</scope>&nbsp; &nbsp; </dependency>&nbsp; &nbsp; <dependency>&nbsp; &nbsp; &nbsp; &nbsp; <groupId>org.apache.tomcat.embed</groupId>&nbsp; &nbsp; &nbsp; &nbsp; <artifactId>tomcat-embed-jasper</artifactId>&nbsp; &nbsp; &nbsp; &nbsp; <scope>provided</scope>&nbsp; &nbsp; </dependency>它应该工作。如需更多参考，您可以按照本教程进行操作https://github.com/spring-projects/spring-boot/tree/v2.1.1.RELEASE/spring-boot-samples/spring-boot-sample-web-jsp
