When I am using tomcat 9 it gives me below error:

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

And when I am using tomcat 8 :

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

it gives me below error:

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    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

It was loaded from the following location:

    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

If anyone can knows how to solve it please help.

Solution

  • Your POM contains some dependencies that has version conflicts with each other.

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

    The 2.3.3.RELEASE version of spring-boot-starter-web is already built with Tomcat 9.0.37

    Tomcat 9 and above is on servlet 4.x

    Removing these the following dependencies from your pom.xml should alleviate your dependency problems.

    <dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
    <scope>provided</scope>
</dependency>

    and

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

    since these are transitive dependencies that are already provided by dependencies in your project.

    You can use mvn dependency:tree -Dverbose to inspect your dependency tree and observe any potential dependency conficts.
