出错所在的方法：

Java code

@PersistenceContext(unitName="YingShe_PU")protected EntityManager em;    public void addPerson(String name, int age, String phone, String address,            String cid, Date valDate) {        Person p = new Person();        Card c = new Card();        c.setCid(cid);        c.setValDate(valDate);        c.setPerson(p);        p.setName(name);        p.setAddress(address);        p.setAge(age);        p.setCard(c);        p.setPhone(phone);        em.persist(p);    }

[解决办法]
像是级联保存的问题。
Card c = new Card();
c.setCid(cid);

先保存c.试试；
em.persist(c);
em.persist(p);

[解决办法]
Card一端没有外键，外键在Person一端。
所以绝不能persist(Person).
只能persist(Card)，继而级联添加Person.

但Card中的注解并没有设置级联添加：
@OneToOne(cascade={CascadeType.MERGE, CascadeType.REMOVE}, optional = false, mappedBy = "card")
private Person person;

应改为：
@OneToOne(cascade=CascadeType.ALL, optional = false, mappedBy = "card")
private Person person;

含有外键的一端应该加入unique表示一对一：
@JoinColumn(name = "cardid", referencedColumnName = "cid",unique="true")
private Card card;


另外，不知道你的数据库使用的是哪种？
如果是SQLServer，主键的注解应该是：
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)

如果是Oracle，主键的注解应该是：
@Id
@SequenceGenerator(name="oid",sequenceName="oid")
@GeneratedValue(strategy = GenerationType.SEQUENCE,generator="oid")

如果是MySQL则可使用AUTO.

添加时则不用指定card的主键值，只需要设置其他属性值即可：

//设置card属性值
//设置person属性值
card.setPerson(person);
person.setCard(card);
em.persist(card);
