Katharsis与Spring Boot的结合

Question

我已经使用Spring Boot (1.3.6.RELEASE版)实现了一个REST API，它可以像预期的那样工作。但是，我想在我的应用程序中添加JSON API支持。

问题是，当我试图在Katharsis资源上执行get时，我得到了一个404。

pom.xml中的依赖关系如下所示(我也使用Spring Security )：

我的应用程序初始化类如下：

@SpringBootApplication
@Configuration
@EnableAutoConfiguration(exclude = WebMvcAutoConfiguration.class)
@EnableSwagger2
@ComponentScan(basePackages = "com.myapp")
@Import({KatharsisConfigV2.class})
public class Application {
    public static void main(String[] args) {
        ApplicationContext ctx = SpringApplication.run(Application.class, args);
    }
}

资源类：

@ApiModel(description = "")
@JsonApiResource(type = "foo-data")
public class FooData extends DomainRepresentation {
    @JsonApiId
    private String id = null;
    @JsonProperty
    private String name = null;
    // .... getters & setters
}

ResourceRepository类：

@JsonApiResourceRepository(FooData.class)
@Component
public class FooDataKatApi extends MyApi {
    @Autowired
    private FooDataService fooDataService;

    @JsonApiFindOne
    public FooData foodataIdGet(String id, QueryParams requestParams) { 
        FooData result = fooDataService.getFooDataById(id);
        return result;
    }
}

如果我添加Spring，那么我会得到返回的数据，但是没有像“@ResourceMapping”这样的Katharsis添加的东西。

任何帮助都将不胜感激。

FooDataService如下：

@Service
public class FooDataService extends MyService {
    @Autowired
    private FooDataRepository fooDataRepository;

    public FooData getFooDataById(String id) {
        FooDataEnt fooDataEnt = fooDataRepository.findByFooDataId(id);

        if (fooDataEnt != null) {
            return convertFooDataEntToFooData.apply(fooDataEnt);
        }

        throw new NotFoundException("Foo not found");
    }
}

FooDataRepository扩展了Spring的PagingAndSortingRepository。

Application.yaml中的Katharsis配置：

katharsis:
    resourcePackage: com.my.package
    domainName: http://localhost:8080
    pathPrefix: /api/kat

The request and response from PostMan

--更新1 --

显然，katharsis.pathPrefix的配置值不正确。Web应用程序的上下文根是"/api“，并且katharsis.pathPrefix的值应该只是"/kat”。

我的下一个问题是在处理请求时抛出了一个RepositoryNotFoundException，而资源类已经被找到了。

Answer 1

我在任何地方都没有看到您的foo数据服务实现。但是，我99%确定您没有传递json api接受类型。

Accept: application/vnd.api+json

Answer 2

通过调试代码并发现我的Katharsis配置不正确，我解决了这个难题。Katharsis只获取资源类，而不获取资源存储库类。当我将katharsis.resourcePackage更改到资源库所在的更高级别时，问题得到了解决，Katharsis获得了所有相关的带注释的类。
