Caused by: java.sql.BatchUpdateException: ORA-00001: 违反唯一约束条件

只有这句clientuser.addCustomer(customer);和这两句clientuser.addCustomer(customer);
         clientuser.addAccount(acc);一起出现的错误如下：
Exception in thread "main" org.springframework.dao.DataIntegrityViolationException: Could not execute JDBC batch update;
nested exception is org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update
at springexample.hibernate.TestClient.main(TestClient.java:39)
Caused by: org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update
Caused by: java.sql.BatchUpdateException: ORA-00001: 违反唯一约束条件 (UNISPOWER.SYS_C0011001)
不是唯一约束的问题，应该是相关属性外键关联的空置问题……
未知？？？？
只有这句clientuser.addAccount(acc);的错误：
Exception in thread "main" org.springframework.dao.DataIntegrityViolationException:
not-null property references a null or transient value: springexample.hibernate.Account.customer;
nested exception is org.hibernate.PropertyValueException: not-null property references a null or transient value:
springexample.hibernate.Account.customer
at springexample.hibernate.TestClient.main(TestClient.java:40)
Caused by: org.hibernate.PropertyValueException: not-null property references a null or transient value:
springexample.hibernate.Account.customer
根据后面语句执行推断，上面的错误，问题可能在于，程序获得RMI服务bean的时候，set过的数据已经存到表中，
再执行addXX方法肯定就不合唯一约束了。

注意getHibernateTemplate().find（）的用法，格式不对害死人啊！写了一个格式不太对的查询，
貌似程序现在还处于死循环状态……等待中ing
