Question

我正在使用一个开源项目将对象转换为Json，它为我提供了处理字段排除的工具。我的servlet.xml代码片段具有相同的外观

<bean id="jsonViewSupport" class="com.monitorjbl.json.JsonViewSupportFactoryBean" />

JsonViewSupportFactoryBean类具有如下方法

/**
   * Registering custom serializer allows to the JSonView to deal with custom serializations for certains field types.<br>
   * This way you could register for instance a JODA serialization as  a DateTimeSerializer. <br>
   * Thus, when JSonView find a field of that type (DateTime), it will delegate the serialization to the serializer specified.<br>
   * @param <T> Type class of the serializer
   * @param cls {@link Class} the class type you want to add a custom serializer
   * @param forType {@link JsonSerializer} the serializer you want to apply for that type
   */
  public <T> void registerCustomSerializer( Class<T> cls, JsonSerializer<T> forType )
  {
      this.converter.registerCustomSerializer( cls, forType );
  }

我有一个DateMapper类，如下所示

public class DateMapper extends JsonSerializer<Date>{

    @Override
    public void serialize(Date dateObje, JsonGenerator jgen, SerializerProvider serializers) throws IOException, JsonProcessingException {
                // TODO Auto-generated method stub
                SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
                jgen.writeString(dateFormat.format(dateObje));
            }
        }

我不确定如何调用此方法，并从servlet.xml中为Date对象设置自定义序列化器。

感谢任何帮助，感谢

如何从servlet.xml调用bean方法？
