在Jackson根据官方文档添加自定义序列化程序后,我观察到了略微不同的json输出格式.

这个例子是基于弹簧垫的叉子.

扩展org.springsource.restbucks.WebConfiguration从RepositoryRestMvcConfiguration并重写configureJacksonObjectMapper:

@Override
protected void configureJacksonObjectMapper(ObjectMapper objectMapper) {
    final SimpleSerializers serializers = new SimpleSerializers();
    serializers.addSerializer(Order.class, new OrderSerializer());
    objectMapper.registerModule(new SimpleModule("CustomSerializerModule"){
        @Override public void setupModule(SetupContext context) {
            context.addSerializers(serializers);
        }
    });
}

创建类org.springsource.restbucks.order.OrderSerializer.为简洁起见,只需将属性写paid为JSON即可.

public class OrderSerializer extends JsonSerializer<Order> {
    @Override
    public void serialize(Order value, JsonGenerator jgen, SerializerProvider provider) throws IOException {
        jgen.writeStartObject();
        jgen.writeBooleanField("paid", value.isPaid());
        jgen.writeEndObject();
    }
}

在添加OrderSerializer json响应之前,http://localhost:8080/orders/1看起来像:

{
  "location": "TAKE_AWAY", …
