NoSuchMethodError: javax.servlet.ServletContext.getVirtualServerName()Ljava/lang_JAVA_编程开发_程序员俱乐部

?

?

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

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();

<!-- servlet 3.0 start -->

?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。
