Serialization 我可以指定在RestEasy中用于方法结果转换的jackson@JsonView吗？

我正在使用基于

@JsonView

的序列化模型。我通常使用

ContextResolver

配置jackson，如下所示：

@Override
public ObjectMapper getContext(Class<?> aClass) {
    // enable a view by default, else Views are not processed
    Class view = Object.class;
    if (aClass.getPackage().getName().startsWith("my.company.entity")) {
        view = getViewNameForClass(aClass);
    }
    objectMapper.setSerializationConfig(
         objectMapper.getSerializationConfig().withView(view));
    return objectMapper;
}

并在视图

JSONEntity

下序列化。RestEasy是否可以做到这一点？如果不是，我该如何效仿

编辑：我知道我可以自己完成序列化：

public String getAll(@Context UriInfo info, @Context Providers factory) {
    List<T> entities = getAll(info.getQueryParameters());
    ObjectMapper mapper = factory.getContextResolver(
         ObjectMapper.class, MediaType.APPLICATION
    ).getContext(entityClass);
    return mapper.writeValueAsString(entities);
}

publicstringgetall（@Context-UriInfo，@Context-Providers-factory）{
List entities=getAll（info.getQueryParameters（））；
ObjectMapper映射器=factory.getContextResolver(
ObjectMapper.class、MediaType.APPLICATION
).getContext（entityClass）；
返回mapper.writeValueAsString（实体）；
}

然而，这充其量是笨拙的，并且挫败了让框架处理这个样板文件的整个想法。

结果是，可以简单地用

@JsonView

注释一个特定的端点（就像在我的问题中一样），jackson将使用这个视图。谁会猜到呢

您甚至可以通过泛型方法（）来实现这一点，但这将我与RestEasy联系在一起：

@Override
public void writeTo(Object value, Class<?> type, Type genericType, 
        Annotation[] annotations,  MediaType mediaType, 
        MultivaluedMap<String, Object> httpHd, 
        OutputStream out) throws IOException {
    Class view = getViewFromType(type, genericType);
    ObjectMapper mapper = locateMapper(type, mediaType);

    Annotation[] myAnn = Arrays.copyOf(annotations, annotations.length + 1);
    myAnn[annotations.length] = new JsonViewQualifier(view);

    super.writeTo(value, type, genericType, myAnn, mediaType, httpHd, out);
}

private Class getViewFromType(Class<?> type, Type genericType) {
    // unwrap collections
    Class target = org.jboss.resteasy.util.Types.getCollectionBaseType(
            type, genericType);
    target = target != null ? target : type;
    try {
        // use my mix-in as view class
        return Class.forName("example.jackson.JSON" + target.getSimpleName());
    } catch (ClassNotFoundException e) {
        LOGGER.info("No view found for {}", target.getSimpleName());
    }
    return Object.class;
}

@覆盖
public void writeTo（对象值、类类型、类型genericType、，
注释[]注释，MediaType MediaType，
多值MAP httpHd，
OutputStream out）抛出IOException{
类视图=getViewFromType（类型，genericType）；
ObjectMapper mapper=locateMapper（类型，mediaType）；
Annotation[]myAnn=Arrays.copyOf（annotations，annotations.length+1）；
myAnn[annotations.length]=新的JsonViewQualifier（视图）；
super.writeTo（value、type、genericType、myAnn、mediaType、httpHd、out）；
}
私有类getViewFromType（类类型，类型genericType）{
//拆封收藏
Class target=org.jboss.resteasy.util.Types.getCollectionBaseType(
类型，泛型）；
target=target！=null？target:type；
试一试{
//使用我的mix-in作为视图类
返回Class.forName（“example.jackson.JSON”+target.getSimpleName（））；
}catch（classnotfounde异常）{
info（“找不到{}的视图”，target.getSimpleName（））；
}
返回Object.class；
}

@Override
public void writeTo(Object value, Class<?> type, Type genericType, 
        Annotation[] annotations,  MediaType mediaType, 
        MultivaluedMap<String, Object> httpHd, 
        OutputStream out) throws IOException {
    Class view = getViewFromType(type, genericType);
    ObjectMapper mapper = locateMapper(type, mediaType);

    Annotation[] myAnn = Arrays.copyOf(annotations, annotations.length + 1);
    myAnn[annotations.length] = new JsonViewQualifier(view);

    super.writeTo(value, type, genericType, myAnn, mediaType, httpHd, out);
}

private Class getViewFromType(Class<?> type, Type genericType) {
    // unwrap collections
    Class target = org.jboss.resteasy.util.Types.getCollectionBaseType(
            type, genericType);
    target = target != null ? target : type;
    try {
        // use my mix-in as view class
        return Class.forName("example.jackson.JSON" + target.getSimpleName());
    } catch (ClassNotFoundException e) {
        LOGGER.info("No view found for {}", target.getSimpleName());
    }
    return Object.class;
