Question

尝试在Servlet容器中启动Spring Boot应用程序时，我遇到了这个奇怪的错误。

相同的WAR通常在独立的Tomcat服务器中启动，但如果使用Gretty Gradle插件启动，则会出现以下错误

这意味着什么？

Spring-boot 1.3.3，Gradle 2.12，Gretty 1.2.4，Tomcat 8

显然，Gretty中存在与类加载相关的错误。用WAR启动Gretty，例如gradlew appRunWar允许解决它。

为它打开了多个错误：

无法找到类'org / springframework / boot / context / web / SpringBootServletInitializer'的数据
