How to override class

Question

I am using the latest version of spring-boot and am trying to add ids to my json entities as described here

If I add this configuration, my JSON responses no longer work:

2015-03-02 11:55:13.949 DEBUG 8288 --- [nio-8080-exec-1] o.s.b.a.e.mvc.EndpointHandlerMapping : Looking up handler method for path /hal/tutorials/1 2015-03-02 11:55:13.951 DEBUG 8288 --- [nio-8080-exec-1] o.s.b.a.e.mvc.EndpointHandlerMapping : Did not find handler method for [/hal/tutorials/1] 2015-03-02 11:55:13.974 DEBUG 8288 --- [nio-8080-exec-1] o.s.b.a.e.mvc.EndpointHandlerMapping : Looking up handler method for path /error 2015-03-02 11:55:13.975 DEBUG 8288 --- [nio-8080-exec-1] o.s.b.a.e.mvc.EndpointHandlerMapping : Did not find handler method for [/error]

Here is my main configuration file, I have tried moving RepositoryConfig into it's own file and using @Component instead of @Configuration but nothing works.

@SpringBootApplication @EntityScan(basePackages = { "com.mypp.domain" }) @EnableJpaRepositories(basePackages = { "com.mypp.repository" }) @EnableTransactionManagement @EnableGlobalMethodSecurity @EnableJpaAuditing @EnableConfigurationProperties public class ShelltorialsApplication { public static void main(String[] args) { SpringApplication.run(ShelltorialsApplication.class, args); } } @Configuration public class RepositoryConfig extends RepositoryRestMvcConfiguration { @Override protected void configureRepositoryRestConfiguration( RepositoryRestConfiguration config) { config.exposeIdsFor(Tutorial.class); } }

What am I doing wrong?

how is your baseuri configured before adding the RepositoryConfig? — ikumen

I got this working, I needed to extend SpringBootRepositoryRestMvcConfiguration not RepositoryRestMvcConfiguration

@Configuration public class RepositoryConfig extends SpringBootRepositoryRestMvcConfiguration { @Override protected void configureRepositoryRestConfiguration( RepositoryRestConfiguration config) { config.exposeIdsFor(Tutorial.class); } }

If you want all your jpa entities to expose their id value, you can do the following

Add this dependency:

<dependency> <groupId>org.reflections</groupId> <artifactId>reflections-maven</artifactId> <version>0.9.9-RC2</version> </dependency>

And modify the configuration as follows.

@Configuration public class RepositoryConfig extends SpringBootRepositoryRestMvcConfiguration { @Override protected void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) { //change com.yourpackage.domain to point to your domain classes Reflections reflections = new Reflections("com.yourpackage.domain"); Set<Class<?>> entities = reflections.getTypesAnnotatedWith(Entity.class, false); config..exposeIdsFor(entities.toArray(new Class[entities.size()])); } }

looks like you ran into the same issue i just did: github.com/spring-projects/spring-boot/issues/2392
