LightAdmin and Spring Boot

[Ilya Davydov]

Are you planning to migrate LightAdmin to Spring Boot?

[Maxim Kharchenko]

Hi Illya, 

Currently, we're working on upgrading Spring Data/Rest to the latest version.

Right after that we'll integrate LightAdmin with Spring Boot ('cause it uses the latest versions as you probably noticed).

Cheers,

Max

Hi Illya,

Take a look at lightadmin-spring-boot for reference implementation.

Spring Boot + LightAdmin configuration example:

@Configuration
@ComponentScan
@EnableAutoConfiguration
@Order(HIGHEST_PRECEDENCE)
public class LightAdminBootApplication extends SpringBootServletInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        LightAdmin.configure(servletContext)
                .basePackage("org.lightadmin.boot.administration")
                .baseUrl("/admin")
                .security(false)
                .backToSiteUrl("http://lightadmin.org");

        super.onStartup(servletContext);
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(LightAdminBootApplication.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(LightAdminBootApplication.class);
    }
}

Feel free to ask in case of any questions.

Cheers,

Hello,

I am trying Light Admin 1.0.0M3 with this exact setup, but it doesn't seem to work. I can't even tell if Light Admin is actually being initialized. How can I debug this?

[Joshua Chaitin-Pollak]

Hi,

I realized my problem was that we are running our Spring Boot application in Embedded mode, which I guess isn't supported yet. I tried adding the servletContextInitializer() found here:

https://github.com/la-team/light-admin/blob/spring-data-upgrade/lightadmin-spring-boot/src/main/java/org/lightadmin/boot/LightAdminBootApplication.java

I realize this is marked as in progress, but when I run this code and then try and access this page, I get a huge stacktrace that starts with:

java.lang.IllegalStateException: ApplicationEventMulticaster not initialized - call 'refresh' before multicasting events via the context: WebApplicationContext for namespace 'lightadmin-dispatcher-servlet': startup

Is there any workaround, even a manual one, that I could apply to get LightAdmin working with an Embedded application? I'd really like to be able to use it but I need to keep my app embedded.

Thanks

Hi mate,

I've just ran LightAdmin + Spring Boot application in tomcat embedded mode.

Please check it out (LightAdmin+SpringBoot)!

Hello,

Thanks.

Hi mate,

Spring Boot integration example has been moved to the separate repository https://github.com/la-team/lightadmin-springboot.

Please check it out and feel free to ask any questions.
