SharedPreferences存取bean

保存bean：

 String myString= Base64.encodeToString(JSON.toJSONString(myBean).getBytes(), Base64.DEFAULT);        getSharedPreferences("myAddress", Context.MODE_PRIVATE).edit()                .putString("myBean",myString).apply();

取出bean：

String myString  = getSharedPreferences("myAddress",Context.MODE_PRIVATE)                .getString("myBean", null);        myBean = myString == null ? null : JSON.parseObject(                new String(Base64.decode(s,Base64.DEFAULT)),myBean.class);
