fastjson Json 操作

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。
