我是spring和hib的新手,我用的是netbeans v.8.2,我用的是spring 3.2.7和hib4.3.x库,我该怎么做才能修复这个错误?
错误:创建在类路径资源[applicationContext.xml]中定义的名为'dao'的Bean时出错:设置Bean属性"template"时无法解析对Bean "template"的引用;嵌套的异常是org. springframework. bean.工厂。创建在类路径资源[applicationContext.xml]中定义的名为"template"的Bean时出错:设置Bean属性"sessionFactory"时无法解析对Bean "mysessionFactory"的引用;嵌套的异常是org. springframework. bean.工厂。创建在类路径资源[applicationContext.xml]中定义的名为"mysessionFactory"的Bean时出错:初始化bean失败;嵌套异常为java. lang. NoClassDefFoundError:org/休眠/缓存/缓存提供程序
这是应用程序context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans

            <prop key="hibernate.show_sql">true</prop>

</bean>  
  
<bean id="dao" class="dao.MahasiswaDao">  
<property name="template" ref="template"></property>  
</bean>  
  
  
</beans>

this is mahasiswa.java (mahasiswa=student in English):

package entity;

public class Mahasiswa  implements java.io.Serializable {

 private String npm;
 private String nama;
 private String jurusan;
 private String alamat;

public Mahasiswa() {
}

public Mahasiswa(String npm, String nama, String jurusan, String alamat) {
   this.npm = npm;
   this.nama = nama;
   this.jurusan = jurusan;
   this.alamat = alamat;
}

public String getNpm() {
    return this.npm;
}

public void setNpm(String npm) {
    this.npm = npm;
}
public String getNama() {
    return this.nama;
}

public void setNama(String nama) {
    this.nama = nama;
}
public String getJurusan() {
    return this.jurusan;
}

public void setJurusan(String jurusan) {
    this.jurusan = jurusan;
}
public String getAlamat() {
    return this.alamat;
}

public void setAlamat(String alamat) {
    this.alamat = alamat;
}

}

这是大般若。道:

package dao;
import entity.Mahasiswa;
import org.springframework.orm.hibernate3.HibernateTemplate;
public class MahasiswaDao {
HibernateTemplate template;
public void setTemplate(HibernateTemplate template) {  
this.template = template;  
}
public void saveMahasiswa(Mahasiswa m){
    template.save(m);
}
}

这个文件是mahasiswa.hbm.xml:

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<!-- Generated Sep 30, 2021 6:57:57 AM by Hibernate Tools 4.3.1 -->
<hibernate-mapping>
<class name="entity.Mahasiswa" table="mahasiswa" catalog="kampus" optimistic-lock="version">
    <id name="npm" type="string">
        <column name="npm" length="13" />
        <generator class="assigned" />
    </id>
    <property name="nama" type="string">
        <column name="nama" length="100" not-null="true" />
    </property>
    <property name="jurusan" type="string">
        <column name="jurusan" length="100" not-null="true" />
    </property>
    <property name="alamat" type="string">
        <column name="alamat" length="100" not-null="true" />
    </property>
</class>
   </hibernate-mapping>

and this is the main.java :

public class test06 {
public static void main(String[] args) {
    Resource r=new ClassPathResource("applicationContext.xml");  
BeanFactory factory=new XmlBeanFactory(r);  
  
MahasiswaDao dao=(MahasiswaDao)factory.getBean("dao");  
  
Mahasiswa m=new Mahasiswa();  
m.setNpm("1");  
m.setNama("test");  
m.setJurusan("");
m.setAlamat("");
  
dao.saveMahasiswa(m); 
}
}

谢啦,谢啦

您将错过classpath上的org.hibernate.cache.Provider类。
按照java.lang.ClassNotFoundException: org.hibernate.cache.CacheProvider exception while integrating spring and hiberate

  • org. hib. cache.Provider在从Hibernate 3到Hibernate 4的变更中被删除 *。

您使用的是Hibernate 4,但是您在applicationContext.xml中使用的Spring中与Hibernate相关的类来自org.springframework.orm.hibernate3包,因此它们需要缺少的依赖项。
尝试使用org.springframework.orm.hibernate4包中的Hibernate模板和LocalSessionFactoryBean。
如果Spring 3.2.7中没有这样的包,请升级到Spring 4。
