Spring boot with Spring web更新spring boot版本后无法加载JSP

Question

最近我将 Spring boot 版本从 2.3.1.RELEASE 更新到 2.5.12.

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.5.12</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

更改版本后，只需稍作修改，我就可以按原样运行代码。 从 STS 运行时，此应用程序运行良好。

运行 mvn clean;mvn install 并生成构建后，当我使用 java -jar 命令启动此应用程序时，应用程序成功运行但无法返回 JSP 页面。

我还在之前版本的 application.properties 中添加了以下代码。

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

我尝试在我的 pom.xml 文件中添加 spring-boot-starter-tomcat 依赖项。我的 pom.xml 中确实已经有 tomcat-embed-jasper（已提供）和 jstl（已提供）依赖项

在调试模式下运行时出现以下错误：

我尝试用 jsp 重命名 WEB-INF 文件夹，但这不起作用。

也试过 mvn:spring-boot 命令但同样的问题。
