转化过程中用的的二方包

        <!--fastjson -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>

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

String -> Date

转date代码

        String dateStr = "2010/05/04 12:34:23";   
        Date date = new Date();   
        //注意format的格式要与日期String的格式相匹配   
        DateFormat sdf = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");   
        try {   
            date = sdf.parse(dateStr);      
        } catch (Exception e) {   
            e.printStackTrace();   
        }  

String -> TimeStamp

        Timestamp ts = new Timestamp(System.currentTimeMillis());   
        String tsStr = "2011-05-09 11:49:45";   
        try {   
            ts = Timestamp.valueOf(tsStr);   
            System.out.println(ts);   
        } catch (Exception e) {   
            e.printStackTrace();   
        }  

TimeStamp -> String

Timestamp ts = new Timestamp(System.currentTimeMillis());   
        String tsStr = "";   
        DateFormat sdf = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");   
        try {   
            //方法一   
            tsStr = sdf.format(ts);   
            System.out.println(tsStr);   
            //方法二   
            tsStr = ts.toString();   
            System.out.println(tsStr);   
        } catch (Exception e) {   
            e.printStackTrace();   
        } 

Date -> Timestamp

new Timestamp((new Date()).getTime())  

Timestamp -> Date

            Timestamp t = new Timestamp(System.currentTimeMillis()); 
            Date d = new Date(t.getTime());
