Spring boot application not starting on Tomcat 7

Question

I am trying to deploy my Spring boot application on a Tomcat 7 server and start it. I am able to deploy, while I am facing problems in starting the server.

What I did ?

1) Created a spring starter project with the initial configurations and dependencies.

2) Edited the 'org.eclipse.wst.common.project.facet.core.xml' file and changed the 'jst.web' version from 3.1 to 3.0. Cleaned the project.

3) Implemented ServletContextInitializer with onStartup method override based on the explicit configuration steps as per https://github.com/spring-projects/spring-boot/issues/522. Code looks like below

@Configuration
public class ContextInitializer implements ServletContextInitializer {

@Override
public void onStartup(ServletContext arg0) throws ServletException {
    // TODO Auto-generated method stub
}

}

and in my Application class

public static void main(String[] args) {
    SpringApplication.run(new Class[] { SocialIntegrationApplication.class, ContextInitializer.class }, args);
}

4) Performed a mvn clean install. Builds successfully.

But when starting the server, I am getting an error as Server Java Web Tomcat 7 Server failed to start.

Could you please help me out. Thanks.

EDIT : Sharing the catalina.out. Not able to see any error though.

There must be more informations in the catalina.out logfile. Please take a lokk and post it here — Jens, Feb 27 '17 at 09:00
Judging by the `ClassCircularityError` it looks like the dependency on `org.slf4j:slf4j-log4j12` is the problem — Andy Wilkinson, Feb 28 '17 at 08:28

Spring Boot and Tomcat 7

pom.xml

version specification:

<properties>
    <tomcat.version>7.0.78</tomcat.version>
    <servlet-api.version>3.0.1</servlet-api.version>
</properties>

dependencies downgrade:

<dependencies>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>${servlet-api.version}</version>
        <scope>provided</scope>  <!-- provided: tomcat/lib/servlet-api.jar -->
    </dependency>
    <dependency>
        <groupId>org.apache.tomcat</groupId>
        <artifactId>tomcat-juli</artifactId>
        <version>${tomcat.version}</version>
        <scope>runtime</scope> <!-- runtime: tomcat/bin/tomcat-juli.jar -->
    </dependency>
    <!-- remove it:
     <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>provided</scope>
    </dependency>
    -->
</dependencies>

Traditional deployment

To create a deployable war file (Tomcat 7) read this guide: https://docs.spring.io/spring-boot/docs/current/reference/html/howto-traditional-deployment.html

<packaging>war</packaging>

override: SpringBootServletInitializer.configure:

@SpringBootApplication
public class Application extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
}

Can you add the following to your pom.xml and try,

<properties>
        <tomcat.version>your tomcat version</tomcat.version>
</properties>

Added. But still the same problem ! – Vishnukk Feb 27 '17 at 09:59
Which is the logger you are using? is it possible to include your pom.xml. or check is there any multiple dependecies for slf4j. – sparrow Feb 27 '17 at 10:05
