I have a Spring Boot App which runs when packaged as standalone jar with command:
java -jar myApp.jar
However, if I the packaging is war in pom.xml, I can't deploy to tomcat server. My app is a rest service which provides rest calls. When I run the app either by using eclipse or through java command, the app responds to rest calls, like:
http://www.spdev.ufu.br:8081/dashboard/rest/chart/getNumeroMetasPorUnidade
The rest provider is Jersey. Could anyone tell me why the war version does not work in tomcat ? I've done some previous research, but with no success:
Spring Boot War deployed to Tomcat
Here is my pom.xml:

This is my Jersey Configuration:
@Component
@ApplicationPath("/dashboard/rest")
public class JerseyConfig extends ResourceConfig {
public JerseyConfig() {
packages("br.ufu.sp.dashboard.rest");
packages("br.ufu.sp.dashboard.model");
packages("br.ufu.sp.dashboard.repository");
packages("br.ufu.sp.dashboard.service");
}
}
and my app configuration:
@SpringBootApplication
@EnableTransactionManagement
public class DashBoardApp extends SpringBootServletInitializer {
public static void main(String[] args) {
new DashBoardApp().configure(new SpringApplicationBuilder(DashBoardApp.class)).run(args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(DashBoardApp.class);
}
}
Update 1: I checked tomcat's log and found out that the context could not be initialized. Here follows the message:
INFO: Spring WebApplicationInitializers detected on classpath: [br.ufu.sp.DashBoardApp@5a8d3b61, org.glassfish.jersey.server.spring.SpringWebApplicationInitializer@5ca8599b, org.springframework.boot.autoconfigure.jersey.JerseyAutoConfiguration@79d5f5ac] set 15, 2015 10:36:47 AM org.apache.catalina.core.ApplicationContext log
INFO: Initializing Spring embedded WebApplicationContext set 15, 2015 10:36:53 AM org.apache.catalina.core.StandardContext listenerStart
SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
java.lang.IllegalStateException: Cannot initialize context because there is already a root application context present - check whether you have multiple ContextLoader* definitions in your web.xml! at org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:299)...
Update 2: According to
https://java.net/jira/si/jira.issueviews:issue-html/JERSEY-2038/JERSEY-2038.html
A class was needed to set the context issue. Anyway, this is not the problem now. Somehow my endpoints are not being loaded, as shows the tomcat log:
[DEBUG] 2015-09-15 11:14:30,278 org.springframework.boot.actuate.endpoint.mvc.EndpointHandlerMapping getHandlerInternal - Looking up handler method for path /rest/chart/getNumeroMetasPorUnidade
