我尝试实现基本的Spring Boot应用程序,但是当进入localhost:8080 /时,出现白标签错误页面。
从https://start.spring.io/(Maven项目,java 8,jar,spring boot 2.3.0)创建了我的项目,并将其导入了eclipse。
在pom.xml中,
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
运行mainapp.java(在src.main.java.project.projectname中)时,它似乎可以正常运行

localhost:8080 /应该给我一个“欢迎”,但是我却遇到了这个Whitelabel错误,知道如何解决这个问题吗?
