我目前正在尝试将spring与spring进行集成。我使用dao设计模式和mysql作为数据库。我试图在数据库中添加contacte实体，但没有添加，也没有显示错误。顺便说一下，我可以获取联系人列表并通过ID获取它，但我无法更新或插入。在休眠时插入实体问题
这是我的背景文件

这是我的了通用的DAO实现了一套
package biz.picosoft.daoImpl;
import java.io.Serializable;
import java.lang.reflect.ParameterizedType;
import java.lang.reflect.Type;
import java.util.List;
import org.springframework.orm.hibernate5.HibernateTemplate;
import org.springframework.transaction.annotation.Transactional;
import dao.GenericDao;
@Transactional(readOnly=false)
public class GenericDaoImp<T> implements GenericDao<T> {
HibernateTemplate template;
protected Class<T> daoType;
public GenericDaoImp() {
Type t = getClass().getGenericSuperclass();
ParameterizedType pt = (ParameterizedType) t;
daoType = (Class) pt.getActualTypeArguments()[0];
}
public HibernateTemplate getTemplate() {
return template;
}
public void setTemplate(HibernateTemplate template) {
this.template = template;
}
public void insert(T t) {
// TODO Auto-generated method stub
template.save(t);
}
public void update(T t) {
// TODO Auto-generated method stub
template.update(t);
}
public void delete(T t) {
// TODO Auto-generated method stub
template.delete(t);
}
public T findById(Class<T> t, String id) {
// TODO Auto-generated method stub
return template.get(t, id);
}
public List<T> findAll() {
// TODO Auto-generated method stub
return template.loadAll(daoType);
}
}
这是我的实体文件
package biz.picosoft.entity;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "Contacte")
public class Contacte implements Serializable {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name = "idContact")
int idContact;
@Column(name = "nom")
String nom;
@Column(name = "mail")
String mail;
@Column(name = "téléphone")
String téléphone;
@Column(name = "adresse")
String adresse;
public Contacte() {
super();
}
public Contacte( String nom, String mail, String téléphone, String adresse) {
super();
this.nom = nom;
this.mail = mail;
this.téléphone = téléphone;
this.adresse = adresse;
}
public long getIdContact() {
return idContact;
}
public void setIdContact(int idContact) {
this.idContact = idContact;
}
public String getNom() {
return nom;
}
public void setNom(String nom) {
this.nom = nom;
}
public String getMail() {
return mail;
}
public void setMail(String mail) {
this.mail = mail;
}
public String getTéléphone() {
return téléphone;
}
public void setTéléphone(String téléphone) {
this.téléphone = téléphone;
}
public String getAdresse() {
return adresse;
}
public void setAdresse(String adresse) {
this.adresse = adresse;
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + (int) (idContact^(idContact >>> 32));
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
Contacte other = (Contacte) obj;
if (idContact != other.idContact)
return false;
return true;
}
}
我contacteDaoImp文件
package biz.picosoft.daoImpl;
import java.util.List;
import org.springframework.orm.hibernate5.HibernateTemplate;
import org.springframework.transaction.annotation.Transactional;
import biz.picosoft.entity.Contacte;
@Transactional(readOnly=false)
public class ContacteDaoImpl extends GenericDaoImp<Contacte> implements ContacteDao{
}
我的主要
package biz.picosoft.mains;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.orm.hibernate5.LocalSessionFactoryBean;
import biz.picosoft.daoImpl.ContacteDaoImpl;
import biz.picosoft.entity.Contacte;
public class TestHibernate {
public static void main(String[] args) {
// TODO Auto-generated method stub
Contacte contacte=new Contacte("fatma", "test2", "test", "test");
ApplicationContext context =
new ClassPathXmlApplicationContext("applicationContext.xml");
contacte.setIdContact (4);
ContacteDaoImpl contacteDaoImpl=(ContacteDaoImpl) context.getBean("d");
System.out.println(contacteDaoImpl.findAll().size());
contacteDaoImpl.insert(contacte);
}
}
你在哪里调用insert或update语句？ main方法中的代码只是获取所有细节，在创建Contacte对象时，您不会调用插入或更新。 –
不，当我改变findall与插入我什么都没有 –
