java - Katharsis 结合 Spring Boot

Question

我已经使用 Spring Boot(版本 1.3.6.RELEASE)实现了 REST API，它按预期工作。但是，我想为我的应用程序添加 JSON API 支持。

问题是我在尝试对 Katharsis 资源执行 GET 时收到 404。

pom.xml 中的依赖如下(我也使用 Spring Security):

我的应用初始化类如下:

@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
}

资源库类:

@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 @ResourceMapping，我会取回数据但没有 Katharsis 添加，如“链接”等。就好像 API 调用没有被 Katharsis 接收，但它已被处理到 Spring 。

如有任何帮助，我们将不胜感激。

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”，katharsis.pathPrefix 的值只能是“/kat”。

我的下一个问题是在处理请求时抛出 RepositoryNotFoundException，而 Resource 类已经找到。

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