Spring 4.2.3 ve fasterxml Jackson 2.7.0 uyumsuz

Question

Daha hızlı bir şekilde xml.jackson 2.6.3'den 2.7.0'a geçiş. Bunun nedeni, Spring'in AbstractJackson2HttpMessageConverter sürümünde kullanılan public JavaType constructType(Type type, Class<?> contextType) yönteminin kaldırılmış olmasıdır. Bunu nasıl düzeltebilirim? İlkbahar 4.2.3 kullanıyorum.

Answer 1

Spring 4.3'te Jackson 2.7 desteği eklenir. https://jira.spring.io/browse/SPR-13483'a bakın.

Şu an için kendi bütünleştirme sınıflarınızı sağlamadan bunu kullanamazsınız.

Her şeyin işe yaraması için (çoğunlukla jenerikler) MappingJackson2HttpMessageConverter'u geçersiz kılmam gerekiyordu.) Jackson 2.7.2

public class MappingJackson27HttpMessageConverter extends MappingJackson2HttpMessageConverter { 

    public MappingJackson27HttpMessageConverter() { 
    } 

    public MappingJackson27HttpMessageConverter(ObjectMapper objectMapper) { 
     super(objectMapper); 
    } 

    @Override 
    public boolean canRead(Type type, Class<?> contextClass, MediaType mediaType) { 
     JavaType javaType = getJavaType(type, contextClass); 
     if (!logger.isWarnEnabled()) { 
      return (this.objectMapper.canDeserialize(javaType) && canRead(mediaType)); 
     } 
     AtomicReference<Throwable> causeRef = new AtomicReference<Throwable>(); 
     if (this.objectMapper.canDeserialize(javaType, causeRef) && canRead(mediaType)) { 
      return true; 
     } 
     Throwable cause = causeRef.get(); 
     if (cause != null) { 
      String msg = "Failed to evaluate deserialization for type " + javaType; 
      if (logger.isDebugEnabled()) { 
       logger.warn(msg, cause); 
      } else { 
       logger.warn(msg + ": " + cause); 
      } 
     } 
     return false; 
    } 

    @Override

      return true; 
     } 
     Throwable cause = causeRef.get(); 
     if (cause != null) { 
      String msg = "Failed to evaluate serialization for type [" + clazz + "]"; 
      if (logger.isDebugEnabled()) { 
       logger.warn(msg, cause);

Answer 3

iyi uyumlu versiyonlarını

1) Bahar fasterxml ile 4.2.4 çalışır veya 2.8.4

2: Aslında Bahar MVC 4.3 ana MappingJackson2HttpMessageConverter yakaladı sadece ediyor Spring 4.3.5, fastxml ile çalışır. Jackson 2.7.0
