创建名为“countriesDao”的bean时发生java错误:自动连线依赖项的注入失败;
我试图启动Tomcat,但当我尝试启动它时,我得到了以下错误
SEVERE: Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'countriesDao': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void com.fexco.helloworld.web.util.CustomHibernateDaoSupport.anyMethodName(org.hibernate.SessionFactory); nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}
国家公园
package com.fexco.helloworld.web.dao;
import com.fexco.helloworld.web.model.Countries;
public interface CountriesDao {
void save(Countries countries);
void update(Countries countries);
void delete(Countries countries);
Countries findByCountry(String country);
}
CountriesDaoImpl的开始
package com.fexco.helloworld.web.dao;
import java.util.List;
import org.springframework.stereotype.Repository;
import com.fexco.helloworld.web.model.Countries;
import com.fexco.helloworld.web.util.CustomHibernateDaoSupport;
@Repository("countriesDao")
public class CountriesDaoImpl extends CustomHibernateDaoSupport implements CountriesDao{
public void save(Countries countries){
getHibernateTemplate().save(countries);
}
......
}
一些应用程序配置。xml
<bean id="countriesDao" class="com.fexco.helloworld.web.dao.CountriesDaoImpl">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
....
<context:annotation-config />
<context:component-scan base-package="com.fexco.helloworld.web" />
<bean
class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>
自定义HibernatedAOSupport类
package com.fexco.helloworld.web.util;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
public abstract class CustomHibernateDaoSupport extends HibernateDaoSupport
{
@Autowired
public void anyMethodName(SessionFactory sessionFactory)
{
setSessionFactory(sessionFactory);
}
}
错误是因为CountriesDaoImpl没有真正实现CountriesDao吗? 有人知道如何解决这个错误吗
谢谢

似乎在dao实现类中没有定义会话工厂。如果尚未定义,则应定义一个,并避免使用这两种配置,因为这会使事情变得一团糟,例如
