示例1: JsonObjectMapperWriter

import org.codehaus.jackson.map.ObjectMapper; //导入方法依赖的package包/类
public JsonObjectMapperWriter(OutputStream output, boolean prettyPrint) throws IOException {
  ObjectMapper mapper = new ObjectMapper();
  mapper.configure(
      SerializationConfig.Feature.CAN_OVERRIDE_ACCESS_MODIFIERS, true);

  // define a module
  SimpleModule module = new SimpleModule("Default Serializer",  
                                         new Version(0, 1, 1, "FINAL"));
  // add various serializers to the module
  //   add default (all-pass) serializer for all rumen specific data types
  module.addSerializer(DataType.class, new DefaultRumenSerializer());
  //   add a serializer to use object.toString() while serializing
  module.addSerializer(ID.class, new ObjectStringSerializer<ID>());
  
  // register the module with the object-mapper
  mapper.registerModule(module);

  mapper.getJsonFactory();
  writer = mapper.getJsonFactory().createJsonGenerator(
      output, JsonEncoding.UTF8);
