上下文初始化失败，Bean创建异常

Question

我有上述异常的问题，请给出指导方针，这是我的代码：

//Calling Class


 package com.company.product.wsai.qb.ws.endpoint;

//DAO Implementation class

}

//Service implementation

public void saveHistory(History history) {
    historyDAO.saveHistory(history);
 }
}

         <property name="sessionFactory" ref="sessionFactory"/>
     </bean>

</beans>

当我在调用类中包含 autowired 时，屏幕截图中出现错误

Answer 1

你的组件扫描也应该涵盖这个包

package com.company.product.wsai.qb.ws.endpoint;

如下编辑你的config.xml，一个组件扫描就足够了。

<context:component-scan base-package="com.jkcsworld.zhara.wsai.qb" />

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="configLocation">
        <value>/resources/hibernate.cfg.xml</value>
    </property>
 </bean>

 <bean id="historyDAO" class="com.jkcsworld.zhara.wsai.qb.dao.historyDAO.HistoryDAOImpl">
     <property name="sessionFactory" ref="sessionFactory"/>
 </bean>

问题是找不到与SendRequestXMLEndpoint.historyService匹配的bean

所以将你的服务标记为

package com.company.product.wsai.qb.historyService;
//imports

@Service // Mark it as service
public class HistoryServiceImpl implements HistoryService {

    @Autowired
    private HistoryDAO historyDAO;


    public void saveHistory(History history) {
        historyDAO.saveHistory(history);
    }
}

Answer 2

@Autowired
    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

修改您的 HistoryDAOImpl 类以使用上述方法。它应该可以工作。
