Spring Boot 1.5.2启动：java.lang.NoSuchMethodError：javax.servlet.ServletContext.getVirtualServerName（）Ljava / lang / String;

Question

我从Spring Boot的1.5.2版中收到以下错误。在跟踪中，它提取了tomcat版本8.5.11，而我正在使用javax.servlet版本3.1。我到处看都说版本3.1应该可以解决此问题，但是即使删除.m2目录下的存储库，我仍然可以使用它。

Answer 1

该方法getVirtualServerName已在Servlet 3.1的ServletContext中添加。查找Java文档的方法getVirtualServerName

此问题可能至少有3个原因：

1. 您的Servlet版本早于3.1。

2. 其他jar的servlet版本低于3.1。

3. 您的tomcat版本早于8

要解决此问题，您可以尝试以下方法。

I.检查您的pom.xml是否包含以下代码。

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

如果您的pom.xml具有上述代码，则仍然会出现该问题。您可以采用第二种方法。

二。检查您的其他罐子是否已引用该javax.servlet-api罐子。例如，org.apache.santuario已经引用了javax.servlet-apijar。pom.xml：

<dependency>  
    <groupId>org.apache.santuario</groupId>  
    <artifactId>xmlsec</artifactId>  
    <version>1.4.3</version>   
</dependency> 

但是当您查看Maven依赖项时，它是指javax.servlet-api版本比3.1早2.3 的jar。

因此您应该排除2.3版本。pom.xml：

<!-- exclude servlet-api 2.3 jar-->  
<dependency>  
    <groupId>org.apache.santuario</groupId>  
    <artifactId>xmlsec</artifactId>  
    <version>1.4.3</version>  
    <exclusions>  
        <exclusion>  
            <groupId>javax.servlet</groupId>  
            <artifactId>servlet-api</artifactId>  
        </exclusion>  
    </exclusions>  
</dependency>  

<!-- servlet-api 3.1 version has getVirtualServerName() -->  
<dependency>  
    <groupId>javax.servlet</groupId>  
    <artifactId>javax.servlet-api</artifactId>  
    <version>3.1.0</version>  
</dependency> 

三，春季启动运行默认的tomcat7。因此，请定义您的tomcat版本8，而不是tomcat7。因此，将代码添加到pom.xml中：

   <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>8.5.5</tomcat.version>
    </properties>

Answer 2

尝试改变

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
    <version>1.5.2.RELEASE</version>
</dependency>

到

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <version>1.5.2.RELEASE</version>
</dependency>
