从xml移动到Java配置时出现VirtualServerName异常

Question

在春季启动中从XML迁移到Java配置时，我收到了以下错误。

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String;

当我从SpringBootServletInitializer扩展类中删除@ImportResource("classpath:applicationContext.xml")时，会出现此错误。

我已经检查了pom依赖层次结构中的servlet api版本，它被设置为3.0.1，并且只有一个servlet api依赖，并且没有冲突的较低版本。

我使用的是春季启动版本1.3.3.RELEASE。

Answer 1

getVirtualServerName已添加到Servlet 3.1的Servlet上下文中。

请将servlet api更新到最新版本。
