I am starting boot with:

But when I open browser with my app
console not appearing
http://localhost:8090/h2-console/
Any hints?
Thank you

Answer 1

Same here, I think it's the Java8TimeDialect Bean, in your case. In my case, I have a DandelionDialect Bean and when I remove it the h2-console works again.... Try removing the Java8TimeDialect to see if the console works.
Something related with the spring boot DispatcherServletAutoConfiguration?, the order in which the servlets are created or mapped? Not really sure...

Answer 2

http.headers().frameOptions().disable();

You can try following configuration class:
import org.h2.server.web.WebServlet;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.filter.ShallowEtagHeaderFilter;
import javax.servlet.DispatcherType;
import java.util.EnumSet;
#Configuration
public class WebConfiguration {
private static final String mapping = "/console/*";
#Bean
public ServletRegistrationBean h2servletRegistration(){
ServletRegistrationBean registrationBean = new ServletRegistrationBean( new WebServlet());
registrationBean.addUrlMappings(mapping);
return registrationBean;
}
#Bean
public FilterRegistrationBean shallowEtagHeaderFilter() {
FilterRegistrationBean registration = new FilterRegistrationBean();
registration.setFilter(new ShallowEtagHeaderFilter());
registration.setDispatcherTypes(EnumSet.allOf(DispatcherType.class));
registration.addUrlPatterns(mapping);
return registration;
}
}
