Spring Data Rest and Cors

by

Indeed, before Spring Data REST 2.6 (Ingalls) only HandlerMapping instances created by Spring MVC WebMvcConfigurationSupport and controllers annotated with @CrossOrigin were CORS aware. But now that DATAREST-573 has been fixed, RepositoryRestConfiguration now exposes a getCorsRegistry() for global setup and @CrossOrigin annotations on repositories are also recognized so this is the recommended approach.

kotlin data class + bean validation jsr 303

by

You need to use Annotation use-site targets since the default for a property declared in the constructor is to target the annotation on the constructor parameter instead of the getter (which will be seen by JavaBeans compliant hosts) when there are multiple options available. Also using a data class might be inappropriate here (see note … Read more

How to map Page to Page in spring-data-rest

by

You can still use the Page.map without lambda expressions: Page<ObjectEntity> entities = objectEntityRepository.findAll(pageable); Page<ObjectDto> dtoPage = entities.map(new Converter<ObjectEntity, ObjectDto>() { @Override public ObjectDto convert(ObjectEntity entity) { ObjectDto dto = new ObjectDto(); // Conversion logic return dto; } });

When to use @RestController vs @RepositoryRestResource

Ok, so the short story is that you want to use the @RepositoryRestResource since this creates a HATEOAS service with Spring JPA. As you can see here adding this annotation and linking it to your Pojo you have a fully functional HATEOAS service without having to implement the repository method or the REST service methods … Read more

Spring Data Rest – Sort by multiple properties

JSON parse error: Can not construct instance of java.time.LocalDate: no String-argument constructor/factory method to deserialize from String value

by

You need jackson dependency for this serialization and deserialization. Add this dependency: Gradle: compile(“com.fasterxml.jackson.datatype:jackson-datatype-jsr310:2.9.4”) Maven: <dependency> <groupId>com.fasterxml.jackson.datatype</groupId> <artifactId>jackson-datatype-jsr310</artifactId> </dependency> After that, You need to tell Jackson ObjectMapper to use JavaTimeModule. To do that, Autowire ObjectMapper in the main class and register JavaTimeModule to it. import javax.annotation.PostConstruct; import com.fasterxml.jackson.databind.ObjectMapper; import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule; @SpringBootApplication public class MockEmployeeApplication { … Read more
