SpringVaadinServlet blocking SpringBoot features - vaadin

Question

In our Muhuru-Bay-Microgrid-Dashboad project we're using code from https://github.com/xpoft/spring-vaadin in an attempt to get Spring Boot and Vaadin to play nicely. The problem - with this approach we can't access many of the other rest service Spring Boot registers at startup such as
/configprops
/health
/dump
/info
/trace
/mappings
/error
/autoconfig
Our startup code looks like:
#Bean
public ServletRegistrationBean servletRegistrationBean() {
final ServletRegistrationBean servletRegistrationBean
= new ServletRegistrationBean(
new ru.xpoft.vaadin.SpringVaadinServlet(),
"/*", "/VAADIN/*");
return servletRegistrationBean;
}
When we try to access Spring Boot's registered REST services we get redirected to /error - which also doesn't work correctly. Any hints greatly appreciated.

Answer 1

Try to use this addon to integrate Spring Boot and Vaadin:
https://github.com/peholmst/vaadin4spring
It's still in beta, but in my opinion it works much better than the Xpoft addon.

Answer 2

Using https://github.com/peholmst/vaadin4spring with Spring Boot, I had the same problem of getting HTTP 404 when accessing the application's other REST services.
What worked for me was to set VaadinServletConfiguration.SERVLET_URL_MAPPING_PARAMETER_NAME in the spring environment to send the Vaadin UI to a different context path (/ui/*):
#SpringBootApplication
public class AppSpringConfig {
public static void main(String[] args) {
new SpringApplicationBuilder(AppSpringConfig.class).initializers(new ApplicationContextInitializer<ConfigurableApplicationContext>() {
public void initialize(ConfigurableApplicationContext applicationContext)
{
ConfigurableEnvironment appEnvironment = applicationContext.getEnvironment();
Properties props = new Properties();
props.put(VaadinServletConfiguration.SERVLET_URL_MAPPING_PARAMETER_NAME, "/ui/*");
PropertySource< ? > source = new PropertiesPropertySource("vaadin", props);
appEnvironment.getPropertySources().addFirst(source);
}
}).run(args);
}
}
