Unable to run my SpringBoot project on traditional tomcat

Question

We have two SpringBoot projects project1(usermgmt) and project2(instrumentsetup). As we need to use the service and entities from project1 in project2, we packaged project1 as jar and added that project1 jar under 'lib' folder of project2 (war)-root directory.

In pom.xml of project2, added below 'dependency' and 'plugin' for the same.

<dependency>
<groupId>com.xyz</groupId>
<artifactId>usermgmt</artifactId>
<version>1.0.0</version>            
<!-- <scope>system</scope>
<systemPath>${basedir}/lib/usermgmt-1.0.0.jar</systemPath> -->
</dependency>


<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-install-plugin</artifactId>                  
    <executions>
        <execution>
            <id>install-external</id>
            <phase>clean</phase>
            <configuration>
                <file>${basedir}/lib/usermgmt_1.jar</file>
                <repositoryLayout>default</repositoryLayout>
                <groupId>com.xyz</groupId>
                <artifactId>usermgmt</artifactId>
                <packaging>jar</packaging>
                <version>1.0.0</version>
                <generatePom>true</generatePom>
            </configuration>
            <goals>
                <goal>install-file</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Our main class of project2 contains the following:

com.xyz.usermgmt

-- project1 package

com.xyz.instrumentsetup

--- project2 package

@SpringBootApplication(scanBasePackages = {"com.xyz.usermgmt","com.xyz.instrumentsetup"})
@EntityScan({"com.xyz.usermgmt","com.xyz.instrumentsetup"})
@EnableJpaRepositories({"com.xyz.usermgmt","com.xyz.instrumentsetup"})
public class InstrumentsetupApplication extends SpringBootServletInitializer implements WebMvcConfigurer 
{   

    private static final Logger log = LoggerFactory.getLogger(InstrumentsetupApplication.class);
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(InstrumentsetupApplication.class).child(UsermgmtApplication.class).logStartupInfo(true);
    }

    public static void main(String[] args) {
        log.info("Start of instrument setup");
        ApplicationContext ctx = new SpringApplicationBuilder(InstrumentsetupApplication.class, UsermgmtApplication.class).run(args);


        log.info("context created in instrument setup:" + ctx);
    }

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").allowedMethods("GET", "POST", "PUT", "DELETE");
    }     

}

Now our problem is that, this scenario works fine with embedded tomcat but not with traditional tomcat. We created war of project2 using sts-4 and tried to deploy that war in tomcat 8.0. Our jdk version - jdk1.8.0_201

error:

Hope someone could guide us in resolving out the issue. Thanks in advance

Have you checked inside your generated WAR file if the "missing" entity is really there? — Gustavo Passini, Jun 21 '19 at 13:27

Which version of spring boot you are using? Latest version requires tomcat 9.

If you are using <artifactId>spring-boot-starter-tomcat</artifactId> and you want to deploy your app on a traditionnal Tomcat, you will have to tell in the build section of your pom.xml to use the provided Tomcat (<scope>provided</scope>). Have a look here for my solution or here for the Spring docs for traditionnal deployment.

I may be wrong because it's the first time I see that the problem come from an unknown class reference.

Thanks for your suggestion GabLeg. Looked into link.Plz find below my pom.xml for war project. Tomcat is already there.But still its not working. – Subashini Jun 22 '19 at 07:06
Sorry unable to attach pom.xml in comments section. But already contains tomcat dependency under but not under. – Subashini Jun 22 '19 at 07:18
