FastJson对JodaTime的处理

当POJO中时间用的是JodaTime时，用FastJson转换时会完全解散，所以需要一个转换器。

仿照com.alibaba.fastjson.serializer.SimpleDateFormatSerializer

import com.alibaba.fastjson.serializer.JSONSerializer;import com.alibaba.fastjson.serializer.ObjectSerializer;import org.joda.time.DateTime;import org.joda.time.format.DateTimeFormat;import java.io.IOException;import java.lang.reflect.Type;public class JodaTimeSerializer implements ObjectSerializer {  private final String pattern;  public JodaTimeSerializer(String pattern) {    this.pattern = pattern;  }  @Override  public void write(JSONSerializer serializer, Object object, Object fieldName,      Type fieldType, int features) throws IOException {    if (object == null) {      serializer.out.writeNull();      return;    }    final DateTime date = (DateTime) object;    serializer.write(date.toString(DateTimeFormat.forPattern(pattern)));  }}

FastJson工具类

import com.alibaba.fastjson.JSON;import com.alibaba.fastjson.JSONObject;import com.alibaba.fastjson.serializer.SerializeConfig;import com.alibaba.fastjson.serializer.SerializerFeature;import org.joda.time.DateTime;import java.util.List;import java.util.Map;import javafx.animation.KeyValue;public class FastJsonUtils {  private static final SerializeConfig config;  static {    config = new SerializeConfig();    config.put(DateTime.class, new JodaTimeSerializer("yyyy-MM-dd'T'HH:mm:ss.SSSZ"));  }  private static final SerializerFeature[] features = {    SerializerFeature.WriteMapNullValue, // 输出空置字段    SerializerFeature.WriteNullListAsEmpty, // list字段如果为null，输出为[]，而不是null    SerializerFeature.WriteNullNumberAsZero, // 数值字段如果为null，输出为0，而不是null    SerializerFeature.WriteNullBooleanAsFalse, // Boolean字段如果为null，输出为false，而不是null    SerializerFeature.WriteNullStringAsEmpty // 字符类型字段如果为null，输出为""，而不是null  };  public static String toJsonString(Object object) {    return JSON.toJSONString(object, config, features);  }  public static String toJsonNoFeatures(Object object) {    return JSON.toJSONString(object, config);  }  public static Object toBean(String text) {    return JSON.parse(text);  }  public static <T> T toBean(String text, Class<T> clazz) {    return JSON.parseObject(text, clazz);  }  // 转换为数组  public static <T> Object[] toArray(String text) {    return toArray(text, null);  }  // 转换为数组  public static <T> Object[] toArray(String text, Class<T> clazz) {    return JSON.parseArray(text, clazz).toArray();  }  // 转换为List  public static <T> List<T> toList(String text, Class<T> clazz) {    return JSON.parseArray(text, clazz);  }  /**   * 将javabean转化为序列化的json字符串   */  public static Object beanToJson(KeyValue keyvalue) {    String textJson = JSON.toJSONString(keyvalue);    Object objectJson = JSON.parse(textJson);    return objectJson;  }  /**   * 将string转化为序列化的json字符串   */  public static Object textToJson(String text) {    Object objectJson = JSON.parse(text);    return objectJson;  }  /**   * json字符串转化为map   */  public static Map stringToCollect(String s) {    Map m = JSONObject.parseObject(s);    return m;  }  /**   * 将map转化为string   */  public static String collectToString(Map m) {    String s = JSONObject.toJSONString(m);    return s;  }}
