阿里巴巴Json工具-Fastjson讲解

Fastjson是阿里巴巴公司开源的速度最快的Json和对象转换工具,一个Java语言编写的JSON处理器。

1、遵循http://json.org标准，为其官方网站收录的参考实现之一。
2、功能qiang打，支持JDK的各种类型，包括基本的JavaBean、Collection、Map、Date、Enum、泛型。
3、无依赖，不需要例外额外的jar，能够直接跑在JDK上。
4、开源，使用Apache License 2.0协议开源。http://code.alibabatech.com/wiki/display/FastJSON/Home

2、主要的使用入口

Fastjson API入口类是com.alibaba.fastjson.JSON，常用的序列化操作都可以在JSON类上的静态方法直接完成。

public static final Object parse(String text); // 把JSON文本parse为JSONObject或者JSONArray
public static final JSONObject parseObject(String text)； // 把JSON文本parse成JSONObject
public static final <T> T parseObject(String text, Class<T> clazz); // 把JSON文本parse为JavaBean
public static final JSONArray parseArray(String text); // 把JSON文本parse成JSONArray
public static final <T> List<T> parseArray(String text, Class<T> clazz); //把JSON文本parse成JavaBean集合
public static final String toJSONString(Object object); // 将JavaBean序列化为JSON文本
public static final String toJSONString(Object object, boolean prettyFormat); // 将JavaBean序列化为带格式的JSON文本
public static final Object toJSON(Object javaObject); //将JavaBean转换为JSONObject或者JSONArray。

//***************************

JSONObject  json = JSON.parseObject(resultScheduleRedis);
JSONArray jsonArrayResultRedis = JSONArray.parseArray(String.valueOf(json.get("result")));



json转 对象

ScheduleDTO resultDTO = JSON.parseObject(json.toJSONString(), new TypeReference<ScheduleDTO>() {});


//**************************************************

3、有关类库的一些说明

SerializeWriter：相当于StringBuffer
JSONArray：相当于List<Object>
JSONObject：相当于Map<String, Object>

JSON反序列化没有真正数组，本质类型都是List<Object>

、fastjson还有很多很高级的特性，比如支持注解、支持全类型序列化，这些都是很好的特性，功能强大，不再讲解。

这是关于FastJson的一个使用Demo，在Java环境下验证的

private int id;
private String name;
public int getId() {

public void setId(int id) {
this.id = id;
}
public String getName() {

public void setName(String name) {
this.name = name;
