无法导入组织。h2.server.web.WebServlet
Cannot import org.h2.server.web.WebServlet
我正在尝试配置我的 spring 引导应用程序以使用 h2 控制台。找了一些文章,都是用的webServlet。但是我无法导入 class,尽管我在 pom.xml 中添加了 h2 依赖项。我收到此错误消息 can not resolve the symbol WebServlet
。我的进口线

h2 不应该是 compile
(而不是 runtime
)依赖项吗?
我遇到了同样的问题,可能运行同样的例子。具有正确的 Maven pom.xml 依赖项,但出于某种原因必须直接从 Maven 下载 h2 驱动程序 jar。然后上面的代码起作用了。去掉"runtime"元素会默认编译
<!-- https://mvnrepository.com/artifact/com.h2database/h2 -->
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.192</version>
</dependency>
只需从您的 h2 依赖项中删除运行时,一切都会好起来的
仅供参考,'runtime' 作用域是设计的默认值。原因在下面的 Github 页中提到。 (我留给你决定)
