Katharsis與Spring Boot結合使用

Question

我已經使用Spring Boot（版本1.3.6.RELEASE）實現了一個REST API，它按預期工作。不過，我想向我的應用程序添加JSON API支持。

問題是我試圖在Katharsis資源上執行GET時得到了404。

在pom.xml中的樣子的依賴如下（我使用Spring Security太）：

我的應用程序初始化類如下：

@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); 
    } 
} 

的資源類：

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

ResourceRepository clas S：

@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; 
    } 
} 

如果我增加了Spring @ResourceMapping比我找回數據，但沒有卡塔西斯增加像「鏈接」等，這是因爲如果API調用沒有被拾起卡塔西斯，但它由Spring處理。

任何幫助，將不勝感激。

的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"); 
    } 
} 

的FooDataRepository擴展Spring的PagingAndSortingRepository。

卡塔西斯配置在application.yaml：

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

顯然對於katharsis.pathPrefix配置的值是不正確的。 Web應用程序的上下文根是「/ api」，katharsis.pathPrefix的值應該只是「/ kat」。

我的下一個問題是在處理請求時正在拋出RepositoryNotFoundException，而Resource類已經找到。

Answer 1

我在任何地方都看不到你的foo數據服務實現。不過，我99％肯定你沒有傳遞json API接受類型。

Accept: application/vnd.api+json 

Answer 2

我通過調試代碼解決了謎題，發現我的Katharsis配置不正確。 Katharsis只拾取資源類而不是資源庫類。當我將katharsis.resourcePackage更改爲資源存儲庫所在的更高級別時，問題得到解決，Katharsis拿起所有相關的註釋類。
