Spring Boot Tomcat Class Not Found

Question

I am migrating my Spring project into Spring Boot. However, when I am running the app I get this exception

I am using this inside my SpringApplication Class

@SpringBootApplication
@ComponentScan(basePackages = "com.app")
public class MyApplication extends SpringBootServletInitializer {

    @Bean
    public EmbeddedServletContainerFactory servletContainer() {
        TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
        return factory;
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application;
    }

    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}

Any ideas as to why I a might be running into this and how can I fix it?

Here is my gradle:

compile('org.springframework.boot:spring-boot-starter-web')
compile group: 'org.springframework.boot', name: 'spring-boot-starter-tomcat', version: '1.5.3.RELEASE'
compile 'org.apache.tomcat:catalina:6.0.53'
compile 'org.apache.tomcat:coyote:6.0.53'

Why the dependencies are `compile` scope? See also http://snacktrace.com/artifacts/org.apache.tomcat/tomcat-coyote/8.0.8/org.apache.coyote.http11.AbstractHttp11JsseProtocol — StanislavL, May 17 '17 at 13:55
You are using spring boot 1.5.3 which uses tomcat 8 but having dependencies to tomcat 6.Try removing `org.apache.tomcat` dependencies and keeping only spring-boot-starter-web dependency. — Issam El-atif, May 17 '17 at 13:58
Thanks @StanislavL ! I was using the 6.0.53 since it was the latest here http://repo1.maven.org/maven2/org/apache/tomcat/coyote/ Did not realize they renamed it to tomcat-coyote — dg428, May 18 '17 at 07:09

Remove:

@Bean
public EmbeddedServletContainerFactory servletContainer() {
    TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
    return factory;
}

Replace:

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application;
    }

with:

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(MyApplication.class);
    }

The spring-boot-starter-web artifact brings in spring-boot-starter-tomcat so no need to include it explicitly in your gradle file, please remove it too.

Remove:

compile 'org.apache.tomcat:catalina:6.0.53'
compile 'org.apache.tomcat:coyote:6.0.53'

Let spring-boot-starter-tomcat (which is a transitive dependency of spring-boot-starter-web) bring the supported version of Tomcat, 8.5.14 when using Spring Boot 1.5.3.RELEASE.

Yup I removed the 6.0.53 dependency and it worked correctly – dg428 May 18 '17 at 07:10 — dg428, May 18 '17 at 07:10

You need to update your maven dependencies, try to execute:

mvn install or mvn package

which will execute a complete maven life cycle.

you can also take a look here:
