springboot 启动报错 ，缺少 public abstract String getVirtualServerName(); 该方法
换用 引入高版本servlet-api，包含getVirtualServerName(）方法 3.1.0 含getVirtualServerName

servlet-api.jar 是否含有 java.lang.NoSuchMethodError: javax.servlet.ServletContext.getVirtualServerName()
引入高版本servlet-api，包含getVirtualServerName(）方法 3.1.0 含
javax.servlet javax.servlet-api 3.1.0
切换 tomcat 版本 选择非默认版本 <tomcat.version>8.5.23</tomcat.version>
UTF-8 UTF-8 1.8 8.5.23 1.7.9 1.0.1
注释 <scope>provided</scope> 如果javax.servlet-api 不存在java.lang.NoSuchMethodError: javax.servlet.ServletContext.getVirtualServerName() Ljava.lang.String
public abstract String getVirtualServerName();
javax.servlet javax.servlet-api 3.1.0 javax.servlet.jsp jsp-api 2.1
maven compile provided 区别
对于scope=compile的情况（默认scope),也就是说这个项目在编译，测试，运行阶段都需要这个artifact对应的jar包在classpath中。
而对于scope=provided的情况，则可以认为这个provided是目标容器已经provide这个artifact。换句话说，它只影响到编译，测试阶段。在编译测试阶段，我们需要这个artifact对应的jar包在classpath中，而在运行阶段，假定目标的容器（比如我们这里的tomcat容器）已经提供了这个jar包，所以无需我们这个artifact对应的jar包了。
