Jackson 대신 Jackson을 사용하도록 springfox를 구성하는 방법

Question

Gson을 사용하여 JsonObjects를 응답으로 보내려고합니다. 이러한 JsonObject는 objectMapper 또는 Gson 대신 수동으로 생성됩니다. Jackson과 관련된 모든 종속성을 제외 시켰습니다. 그것은 잘 작동합니다. 나중에 springfox를 사용하여 Swagger 문서를 추가하려고했습니다. 지금은 예외 아래 발생 :

Answer 1

예외로 인해 springfox.documentation.spring.web.ObjectMapperConfigurer 이 com.fasterxml.jackson.databind.ObjectMapper 누락에 대해 불평이다.

ObjectMapper은 com.fasterxml.jackson.core:jackson-databind:jar에 있습니다. Springfox로 응용 프로그램을 작동 시키려면 여전히 jackson-databind JAR이 필요합니다.

SpringFox는 Gson과 함께 작동하지 않습니다. Gson 개체를 사용하여 사용자 지정 serializers을 다른 Springfox 아티팩트에 등록해야합니다.

Gson gson = GsonBuilder() 
    // needed for making calls to /v2/api-docs 
    .registerTypeAdapter(Json.class, 
     new SpringfoxJsonSerializer()) 
    // rest are needed for making calls to /swagger-ui.html 
    .registerTypeAdapter(ApiListing.class, 
     new SpringfoxApiListingJsonSerializer()) 
    .registerTypeAdapter(SwaggerResource.class, 
     new SpringfoxResourceJsonSerializer()) 
    .registerTypeAdapter(ResourceListing.class, 
     new SpringfoxResourceListingJsonSerializer()) 
    .registerTypeAdapter(UiConfiguration.class, 
     new SpringfoxUiConfigurationJsonSerializer()) 
    // needed if you have security 
    .registerTypeAdapter(SecurityConfiguration.class, 
     new SpringfoxSecurityConfigurationJsonSerializer()) 
    ... 
    .create(); 

Here 봄 부팅, SpringFox 및 GSON로 동작하는 예제입니다. 의
