我正在使用 jsf hibernate spring primefaces 的集成。我想更新一条记录。但我的代码不起作用。插入和删除效果很好。我没有错误。请帮我写正确的代码。个人道.java

public class PersonelDao implements IPersonelDao {
private SessionFactory sessionFactory;


public SessionFactory getSessionFactory() {
    return sessionFactory;
}

public void setSessionFactory(SessionFactory sessionFactory) {
    this.sessionFactory = sessionFactory;
public void updatePersonel(Personel personel) {

    getSessionFactory().getCurrentSession().update(personel);
    }
public void deletePersonel(Personel personel) {
    getSessionFactory().getCurrentSession().delete(personel);

}

个人服务.java

@Transactional(readOnly=true)
public class PersonelService implements IPersonelService{
    IPersonelDao personeldao;
    public IPersonelDao getPersoneldao() {
        return personeldao;
    }

    public void setPersoneldao(IPersonelDao personeldao) {
        this.personeldao = personeldao;
    }

    @Transactional(readOnly=true)
    public void updatePersonel(Personel personel){
    getPersoneldao().updatePersonel(personel);
}
    @Transactional(readOnly=false)

    public void deletePersonel(Personel personel) {
        getPersoneldao().deletePersonel(personel);

    }

PersonelBean.java

@ManagedBean(name="personelMB")
@RequestScoped
public class PersonelBean implements Serializable{
    private static final long serialVersionUID = 1L;

    @ManagedProperty(value="#{PersonelService}")
    IPersonelService personelservice;
    List<Personel> personelList;

    private int personel_id;
    private String pname;
    private String pfamily;
    private String paddress;
    private String pphone;
//getter and setter
public void deletePersonel(int personel_id){
        Personel personel=(Personel)personelservice.getPersonelId(personel_id);
        getPersonelservice().deletePersonel(personel);


    }

    public void updatePersonel(RowEditEvent event){
    Personel personel = (Personel)event.getObject();
    getPersonelservice().updatePersonel(personel);
        //getDataFromDatabase();
    }

}

  1. 使用p:commandButton而不是h:commandButton
  2. 设置更新属性p:commandButton

请记住，在更新属性中找到正确的 id 可能有点棘手

抱歉，我误解了这个问题正确的答案是：将您的更新方法更改为：

public void updatePersonel(RowEditEvent event){
Personel updated = (Pesonel)event.getObject();
//this is the updated value from the dataTable, get the entity from db and do the update

}

还有一件事：不要更新 ajax 事件上的行，因为您没有更新personelListupdate 方法中的 。这意味着rowEditajax 事件必须是这样的：

<p:ajax event="rowEdit" listener="#{personelMB.updatePersonel}"/>

像这样更改 ManagedBean 的 updatePersonel() 方法

    public void updatePersonel(int personel_id,String pname,String pfamily,String paddress,String pphone){
    Personel personel = new Personel();
    personel=(Personel)personelservice.getPersonelId(personel_id);
    if(personal != null) {
       personel.setPaddress(getPaddress());
       personel.setPersonel_id(getPersonel_id());
       personel.setPfamily(getPfamily());
       personel.setPname(getPname());
       personel.setPphone(getPphone());
       getPersonelservice().updatePersonel(personel_id, pname, pfamily, paddress, pphone);
    }
}
