在我的Eclipse控制台中，所有字段都在更新。像这样：

Hibernate: update FOURNISSEURS set NOM=?, TELEPHONE=?, DATE_AJOUT=?, DATE_MODIFICATION=?, id_adresse=? where ID_FOURNISSEUR=?

# 1 楼答案

解决方案是：

public class FournisseurDaoImpl implements IFournisseurDao {
    @PersistenceContext
    private EntityManager em;
public void modifierFournisseurJPA(Fournisseurs fournisseur) {
        em.merge(fournisseur);
    }
...
}

# 2 楼答案

调用modifierFournisseur(Fournisseurs fournisseur)时，创建一个新的Fournisseurs对象，并设置Id和要更新的相应字段

它应该只更新您在附加的JPA对象中设置的字段
# 3 楼答案

当你使用hbm时。xml必须在类节点中设置属性dynamic update=“true”。默认值为false，这就是所有列都会更新的原因

见： http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/mapping.html#mapping-declaration-class

有 Java 编程相关的问题?

java通过hibernate只更新选定的字段，而不是数据库中的所有列
