Answer 1

您缺少 servlet-api 依赖项，如您在

中看到的那样

Caused by: java.lang.ClassNotFoundException: javax.servlet.ServletContext
at java.net.URLClassLoader.findClass(URLClassLoader.java:381) ~[na:1.8.0_73]
at java.lang.ClassLoader.loadClass(ClassLoader.java:424) ~[na:1.8.0_73]

at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ~[na:1.8.0_73]
... 25 common frames omitted

依赖项“jSTL”对 servlet-api 有暂时依赖项，但在依赖项链中的某个位置可能存在“提供”范围，因此不会传播依赖项。

“platform-b​​on”定义了“servlet-api”，因此您只需添加到您的 pom

 <dependency>
       <groupId>javax.servlet</groupId>
      <artifactId>javax.servlet-api</artifactId>
   </dependency>

你应该可以开始了。
