Spring Data's Page and @JSONVIEW solution

README.md

These two pieces of code above (the PageSerializer class and Spring's @Configuration class) are intended to be included in a Spring Boot application (tested on version 1.4.2).

The custom serializer takes care of serializing org.springframework.data.domain.Page instances returned by a @RestController that uses @JsonView.

It will fully serialize the Page object, albeit not having a matching @JsonView, but will process all @JsonView annotations in the objects contained in that Page.

More on performance using JPA lazy fetching and JSON serializing with @JsonView in this link. https://github.com/mefernandez/spring-jpa-lazy-projections

Employee.java

@Entity
public class Employee {

	@Id
	@GeneratedValue
	private Long id;

	@JsonView(SummaryView.class)
	private String name;

	@JsonView(SummaryView.class)
	@ManyToOne(fetch=FetchType.LAZY)
	private Department department;

	@ManyToOne(fetch=FetchType.LAZY)
	private Employee boss;
}

EmployeeRestController.java

@RestController
public class EmployeeRestController {
	
	@Autowired
	private EmployeeRepository employeeRepository;

	@JsonView(SummaryView.class)
	@RequestMapping(method = RequestMethod.GET, value = "/lazy/employees")
	public Page<Employee> search(Pageable pageable) {
		return employeeRepository.findAll(pageable);
	}
}

PageSerializer.java

public class PageSerializer extends StdSerializer<pageimpl> {
	
	public PageSerializer() {
		super(PageImpl.class);
	}

	@Override
	public void serialize(PageImpl value, JsonGenerator gen, SerializerProvider provider) throws IOException {
		gen.writeStartObject();
		gen.writeNumberField("number", value.getNumber());
		gen.writeNumberField("numberOfElements", value.getNumberOfElements());
		gen.writeNumberField("totalElements", value.getTotalElements());
		gen.writeNumberField("totalPages", value.getTotalPages());
		gen.writeNumberField("size", value.getSize());
		gen.writeFieldName("content");
		provider.defaultSerializeValue(value.getContent(), gen);
		gen.writeEndObject();
	}

}

SpringApplicationConfiguration.java

@Configuration
public class SpringApplicationConfiguration {
  
	@Bean
	public Module jacksonHibernate4Module() {
		Hibernate4Module module = new Hibernate4Module();
		module.enable(Hibernate4Module.Feature.FORCE_LAZY_LOADING);
		return module;
	}  

	@Bean
	public Module jacksonPageWithJsonViewModule() {
		SimpleModule module = new SimpleModule("jackson-page-with-jsonview", Version.unknownVersion());
		module.addSerializer(PageImpl.class, new PageSerializer());
		return module;
	}

}

Works, thanks! Didn't have to use

@Bean
	public Module jacksonHibernate4Module() {
		Hibernate4Module module = new Hibernate4Module();
		module.enable(Hibernate4Module.Feature.FORCE_LAZY_LOADING);
		return module;
	}

@Bean
	public Module jacksonHibernate4Module() {

That is for those who uses JPA models in response serialization.
