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

 

 

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

 

 <dependency>  
    <groupId>javax.servlet</groupId>  
    <artifactId>javax.servlet-api</artifactId>  
    <version>3.1.0</version>  
</dependency>

 

 

切换 tomcat 版本 选择非默认版本 <tomcat.version>8.5.23</tomcat.version>

 

 

<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.8</java.version>
 		<tomcat.version>8.5.23</tomcat.version>  
		<org.slf4j-version>1.7.9</org.slf4j-version>
		<org.logback-version>1.0.1</org.logback-version>
		
	</properties>

 

 

 

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 -->
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>javax.servlet-api</artifactId>
			 <version>3.1.0</version> 
			<!--   <scope>provided</scope>   -->
		</dependency>
		<dependency>
			<groupId>javax.servlet.jsp</groupId>
			<artifactId>jsp-api</artifactId>
			<version>2.1</version> 
			<!--  <scope>provided</scope>   -->
		</dependency>
<!-- servlet 3.0 end -->

 

 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。
