java类在clob表中使用json格式的存取

public void testSerializeObject() throws Exception{
MngTeller oper = new MngTeller();
oper.setIdTeller("003");
oper.setTellerType(RoleType.ADMIN);
oper.setTellerName("管理员");
oper.setDepartNo("00001");
oper.setPassword("123456");

MngContent mc = new MngContent();
//处理成jsonString类型，存入大字段content中
JSONObject object = JSONObject.fromObject(oper);
String str = object.toString();
mc.setContent(str);
mc = mngContentDao.addMngContent(mc);
System.out.println("------------------");
System.out.println("mc.getContent()=" + mc.getContent());
//根据id查找指令
MngContent mcc = mngContentDao.getMngContentById(mc.getIdContent());
System.out.println("----------------------");
System.out.println("mcc.getContent()=" + mcc.getContent());
//反序列化指令，由指令类调用。指令类存action和method，加oper2参数执行待办指令
MngTeller oper2 = (MngTeller) JSONObject.toBean(JSONObject.fromObject(mcc.getContent()), MngTeller.class);
System.out.println("-------------------------");
System.out.println("oper2.getTellerName()=" + oper2.getTellerName());
}
