Spring Data Rest @RepositoryRestController and @RequestMapping

Question

I want to override @RepositoryRestResource autogenerated controller methods using @RepositoryRestController having set the SDR's Base Path to "/api".

Spring Data Rest 3.0 (and earlier) says:

"This controller [as shown in the snippet] will be served from the same API base path defined in RepositoryRestConfiguration.setBasePath that is used by all other RESTful endpoints (e.g. /api)". https://docs.spring.io/spring-data/rest/docs/3.0.1.RELEASE/reference/html/#customizing-sdr.overriding-sdr-response-handlers (chapter 15.4)

This code snippet DOES NOT have a @RequestMapping on the class level, though.

My SDR app is configured with RepositoryRestConfiguration object

config.setBasePath("/api");

and yet @RepositoryRestController doesn't override SDR's autogenerated controller methods.

Please consider the accepted answear to this post: Spring Data Rest controllers: behaviour and usage of @BasePathAwareController, @RepositoryRestController, @Controller and @RestController

Please help me understand this! :)

AppConf.java:

@Configuration @Import(value = {DataConf.class}) @EnableWebMvc @ComponentScan(value = "pl.mydomain.controller") public class AppConf { @Bean public RepositoryRestConfigurer repositoryRestConfigurer() { return new RepositoryRestConfigurerAdapter() { public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) { config.setBasePath("/api"); } }; } }

TokenController.java:

@RepositoryRestController public class TokenController { private TokenRepository repository; @Autowired public TokenController(TokenRepository tokenRepository) { this.repository = tokenRepository; } @RequestMapping(method = GET, path = "/tokens") public @ResponseBody ResponseEntity<?> tokens() { return ResponseEntity.ok("Hello"); } }

TokenRepository.java:

@RepositoryRestResource(path = "tokens") public interface TokenRepository extends CrudRepository<Token, Long>{ }

@marc-tarin, yes, the topic you've pointed out is ok, but what if you set the base path for SDR. Things change... My controller doesn't override autogen. methods. — Błażej Kocik

The key to resolve the above dilemma was configuring the project in a correct fashion. That is, to put @ComponentScan in the class passed to AbstractAnnotationConfigDispatcherServletInitializer::getServletConfigClasses() method (not in AppConf.java passed to getRootConfigClasses()).

DispatcherConf.java:

public class DispatcherConf extends AbstractAnnotationConfigDispatcherServletInitializer { @Override protected Class<?>[] getRootConfigClasses() { return new Class[] {AppConf.class}; } @Override protected Class<?>[] getServletConfigClasses() { return new Class[] {WebConf.class}; // !!! } @Override protected String[] getServletMappings() { return new String[] {"/*"}; } }

AppConf.java:

@Configuration @Import({DataConf.class}) public class ApplicationConf { @Bean public RepositoryRestConfigurer repositoryRestConfigurer() { return new RepositoryRestConfigurerAdapter() { @Override public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) { config.setBasePath("/api"); // !!! } }; } }

DataConf.java:

@Configuration @EnableJpaRepositories(basePackages = { "pl.example.data.repository" }) @EnableTransactionManagement public class DataConf { ... }

WebConf.java:

@Import(RepositoryRestMvcConfiguration.class) @ComponentScan({"pl.example.api.controller"}) // !!! public class WebConf { }

Even if I solved the riddle I don't understand why it was an issue. The rather that https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/context/annotation/ComponentScan.html states:

Annotation Type ComponentScan onfigures component scanning directives for use with @Configuration classes.
