Tomcat Mapper class not found - java

I am creating a web app and at the moment I'm trying to get a tomcat server to run. However I get this error message when ran from the cmd line.

And finally my tomcat server code:
public void createTomcatServer() throws ServletException, LifecycleException{
Tomcat tomcat = null;
Integer webPort = new Integer(9696);
tomcat.setPort(webPort);
tomcat.addWebapp("/", new File(webappDirLocation).getAbsolutePath());
System.out.println("configuring app with basedir: " + new File("./" + webappDirLocation).getAbsolutePath());
tomcat.start();
tomcat.getServer().await();
}
I thought I had included all the correct dependencies, etc. But I just cant find out why its not working - I've looked all over google already - so any help would be greatly appreciated.


I encountered the same problem as well and solved it by depending on the embed module instead.
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-core</artifactId>
<version>${embedded.tomcat.version}</version>

Spring Cloud Function with AWS API Gateway and AWS Lambda

Using the handler org.springframework.cloud.function.adapter.aws.FunctionInvoker::handleRequest I'm receiving the following error when calling my API Gateway endpoint with the payload below. The function is found and it runs the business logic correctly until it returns and throws this NullPointerException:

However, according to the documentation I should be using the handler org.springframework.cloud.function.adapter.aws.SpringBootApiGatewayRequestHandler::handleRequest but when I do so it does not find the function. I have set both FUNCTION_NAME and MAIN_CLASS environment variables to their respective values.

This is the documentation I'm working from: https://docs.spring.io/spring-cloud-function/docs/4.0.0-SNAPSHOT/reference/html/aws.html
Update
I switched the spring-cloud-function version from 4.0.0.RELEASE to 3.2.6 and updated the Function class to remove the Message types. The lambda succeeds in test but fails when making the request from Postman to the API Gateway.
Function
public class Makeuser implements Function<APIGatewayRequest, User> {
#Override
public Message<User> apply(APIGatewayRequest request) {
...
return user;
}
}

My solution is
Add #Tag annotation before each test which I want to run
Add tag under the maven-surefire-plugin, e.g integration
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<groups>integration</groups>
</configuration>
</plugin>
Run maven command: mvn test -Dgroups="integration"

proxyBeanMthods annotation error when running springboot application

I am trying to run my first springboot application but facing some issues.
In my application file, this is my code
package com.clog.ServiceMgmt;
import java.util.List;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
#SpringBootApplication
#EntityScan("models")
#ComponentScan({"com.clog.ServiceMgmt","controllers", "models", "repositories"})
#EnableJpaRepositories(basePackages={"repositories"})
public class ServiceMgmtApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceMgmtApplication.class, args);
}
}
but when i run my application, i get the following error. confused as to why i should get this error and how to solve it.
org.springframework.core.annotation.AnnotationConfigurationException:

Does anyone have an idea of how to fix this issue?
Thanks

" proxyBeanMethods is new in 5.2 and I can see 5.1.2.RELEASE in some elements of the stack."
do a dependency:tree and double check that spring match >= 5.2, I had a similar issue and one library brought 5.1 overriding v5.2 from springboot

Had same problem few days ago. Try to change spring-boot-starter-parent version to 2.1.3.RELEASE, thats resolved my problem.

use this in your main springboot application class :#SpringBootApplication(proxyBeanMethods = false)
this will work .

I had this error happen in a Spring Boot project where I added a custom dependency that made use of Spring (not Spring Boot). The issue in my custom dependency was that it had the following plugin configuration:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.4.3</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer
implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>com.example.Main</mainClass>
<manifestEntries>
<Implementation-Title>${project.name}</Implementation-Title>
<Implementation-Version>${project.version}</Implementation-Version>
<Implementation-Vendor>Vendor Name, ${timestamp}</Implementation-Vendor>
</manifestEntries>
</transformer>
</transformers>
<createDependencyReducedPom>false</createDependencyReducedPom>
</configuration>
</execution>
</executions>
</plugin>
Once I removed the shade plugin from my custom dependency, the error disappeared.

I removed the following dependency
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot</artifactId>
<version>2.2.1.RELEASE</version>
</dependency>
And the code was up like magic

You need to add dependency on log4j
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
to your pom.xml file (after dependency on junit).
You can read about this dependency in maven repo:
http://mvnrepository.com/artifact/log4j/log4j/1.2.17

Project Vaadin with Maven

I am busy developing a Vaadin with Maven project. I would like to integrate Hibernate with this project, but I can't do it.
I've added the dependencies and libraries, but Hibernate does not work.
This is the pom.xml

If you are including just hibernate-entitymanager Maven will download hibernate-core, hibernate-annotations and hibernate-commons-annotations on it's own in the right version.
