我使用JBOSS Hibernate工具对MS SQL Server进行反向工程以获取我的数据模型对象。
然后我用Java编写了一个小型测试程序来打开一个会话，使用配置，实例化一个Customer对象，将其持久化到数据库中。
该示例运行将一条记录写入数据库并关闭会话。
奇怪的是，我之前从未见过的是将“东方”字符保存到数据库列中。
数据库：
Windows 2012 R2 Standard上的SQL Server（Express）10.50.1600 列customerCode和customerName是nvarchar，null Java App：Eclipse Neon，Maven，Hibernate 4.3，Java 1.8
注意：我是Hibernate的新手。
还有什么我可以尝试或重构？
我试过的东西用IBM数据工作室做一个SQL插件（成功）
没有成功
公共类SqlServerDialectWithNvarchar扩展org.hibernate.dialect.SQLServerDialect {
public SqlServerDialectWithNvarchar(){
registerHibernateType(Types.NVARCHAR, 4000, "string");
registerColumnType(Types.BIGINT, "bigint");

主程序：
public static void main(String[] args) {
String btnName = "OrderTrack.java ";
System.out.println(btnName + " started.");
System.out.println(btnName + " hibernate.enh-tas.cfg.xml");
Configuration cfg1 = new Configuration();
cfg1.configure("/hibernate.enh-tas.cfg.xml");
SessionFactory sf1 = cfg1.configure().buildSessionFactory();
System.out.println(btnName + " open hibernate session.");
Session session = sf1.openSession();
session.beginTransaction();
TblCustomers customer = new TblCustomers();
customer.setCustomerName("TEST XXX");
customer.setCustomerCode("DELETE ME");
session.persist(customer);
session.getTransaction().commit();
System.out.println(btnName + " closing hibernate session.");
session.close();
System.out.println(btnName + " session closed.");
}
主程序运行后使用IBM Data Studio进行SELECT查询

更改实体类TblCustomers中的字段，其类型可序列化为String。
例如：改变
private Serializable customerCode;
至
private String customerCode;
也可以更改相应的setter和getter方法。
然后尝试运行您的应用程序
