Problem
Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.springframework.boot.autoconfigure.web.embedded.TomcatWebServerFactoryCustomizer.customizeMaxHttpRequestHeaderSize(TomcatWebServerFactoryCustomizer.java:265)
The following method did not exist:
'void org.apache.coyote.http11.AbstractHttp11Protocol.setMaxHttpRequestHeaderSize(int)'
The calling method's class, org.springframework.boot.autoconfigure.web.embedded.TomcatWebServerFactoryCustomizer, was loaded from the following location:
jar:file:/C:/Users/Josiah/.m2/repository/org/springframework/boot/spring-boot-autoconfigure/3.1.5/spring-boot-autoconfigure-3.1.5.jar!/org/springframework/boot/autoconfigure/web/embedded/TomcatWebServerFactoryCustomizer.class
The called method's class, org.apache.coyote.http11.AbstractHttp11Protocol, is available from the following locations:
jar:file:/C:/Tools/apache-tomcat-9.0.60/lib/tomcat-coyote.jar!/org/apache/coyote/http11/AbstractHttp11Protocol.class
jar:file:/C:/Users/Josiah/.m2/repository/org/apache/tomcat/embed/tomcat-embed-core/10.1.15/tomcat-embed-core-10.1.15.jar!/org/apache/coyote/http11/AbstractHttp11Protocol.class
The called method's class hierarchy was loaded from the following locations:
org.apache.coyote.http11.AbstractHttp11Protocol: file:/C:/Tools/apache-tomcat-9.0.60/lib/tomcat-coyote.jar
org.apache.coyote.AbstractProtocol: file:/C:/Tools/apache-tomcat-9.0.60/lib/tomcat-coyote.jar
Action:
Correct the classpath of your application so that it contains compatible versions of the classes org.springframework.boot.autoconfigure.web.embedded.TomcatWebServerFactoryCustomizer and org.apache.coyote.http11.AbstractHttp11Protocol
cause
As the error message explains, you have two versions of the spring-boot-actuator-autoconfigure JAR on your classpath. You should only have one and it should be the version that is consistent and compatible with the other versions of dependencies in your application. This is not a Micrometer issue.
