Tomcat 7 start failed with srpingboot - spring

Question

I have a spring-boot app (Tomcat 7, Jdk 1.8, maven) that I try to run (It is not a embedded tomcat) and I got several issues like :
Exception in thread "restartedMain" java.lang.reflect.InvocationTargetException

What's wrong ?
My class main :
#SpringBootApplication
public class OWebApplicationInitializer extends SpringBootServletInitializer {
public static void main(String[] args) {
new SpringApplication(OWebApplicationInitializer.class).run(args);
}
}
And my pom like that :
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>

</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
Someone have idea with this issue ?

Answer 1

You have mismatched versions of your dependencies on the classpath.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.0.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
And use Tomcat 8.

Answer 2

You can override SpringBootServletInitializer's configure:
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(OWebApplicationInitializer.class);
}
