请帮助我，因为我无法在springboot应用程序中找出问题所在。我正在使用以下pom.xml 

<parent>
    <groupId>org.springframework.boot</groupId>

当我使用tomcat 9时，出现以下错误：

java.lang.NoSuchMethodError: javax.servlet.http.HttpServletRequest.getHttpServletMapping()Ljavax/servlet/http/HttpServletMapping;

当我使用tomcat 8时：

<tomcat.version>8.5.50</tomcat.version>

它给我下面的错误：

说明：

试图调用一个不存在的方法。尝试是 从以下位置制成：

    org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory.getWebServer(TomcatServletWebServerFactory.java:175)

The following method did not exist:

    org.apache.tomcat.util.modeler.Registry.disableRegistry()V

The method's class, org.apache.tomcat.util.modeler.Registry, is available from the following locations:

    jar:file:/tomcat/embed/tomcat-embed-core/8.5.50/tomcat-embed-core-8.5.50.jar!/org/apache/tomcat/util/modeler/Registry.class

它是从以下位置加载的：

    file:/tomcat/embed/tomcat-embed-core/8.5.50/tomcat-embed-core-8.5.50.jar

Correct the classpath of your application so that it contains a single, compatible version of org.apache.tomcat.util.modeler.Registry

如果任何人都知道如何解决，请提供帮助。

您的POM包含一些依赖项，这些依赖项之间存在版本冲突。

Tomcat 9及更高版本位于servlet 4.x上

从2.3.3.RELEASE中删除以下依赖项，可以缓解依赖项问题。

spring-boot-starter-web

和

9.0.37

因为这些是可传递的依赖项，而这些依赖项已经由项目中的依赖项提供。

您可以使用pom.xml检查您的依赖关系树并观察任何潜在的依赖冲突。

答案 1 :(得分：1)

我有一个类似的问题，原因是jsp-api不适合相应的servlet-api版本。正如SvenDöring已经提到的那样，Spring Boot 2.1.x使用Tomcat 9，后者使用/提供了Servlet API v4。为此，您需要jsp-api 2.3.3，否则可能会收到NoSuchMethodError。

<dependency>
    <groupId>javax.servlet.jsp</groupId>
    <artifactId>javax.servlet.jsp-api</artifactId>
    <version>2.3.3</version>
    <scope>provided</scope>
</dependency>

有关版本匹配的更多信息，可以在这里找到： enter image description here 不幸的是，该列表中缺少Tomcat 9和Servlet-API 4。

答案 2 :(得分：1)

缺少的方法HttpServletRequest.getHttpServletMapping()已添加到版本4的Servlet API中，因此问题是由您对Servlet 3.1 API的依赖引起的：

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

spring-boot-starter-web已包含对Servlet API的依赖，因此无需声明。从您的pom.xml中删除上述内容应该可以解决您的问题。
