解决方案 »

  1.   

    看异常，应该是TrainingDaoImpl类中没注入TrainingIdDao。
    你看看spring文件中是不是写漏了，或者TrainingDaoImpl中没写TrainingIdDao对象的set方法。
      

  2.   

    TrainingIdDao的代码
    package com.team.ehr.dao.impl;
    import java.io.Serializable;
    import java.util.List;
    import org.hibernate.criterion.DetachedCriteria;
    import com.team.ehr.dao.TrainingDao;
    import com.team.ehr.entity.Training;
    public class TrainingDaoImpl extends BaseDao implements TrainingDao {
    public void delete(Training training) {
    // TODO Auto-generated method stub
    super.delete(training);
    }
    public void save(Training training) {
    // TODO Auto-generated method stub
    super.save(training);
    }
    public void update(Training training) {
    // TODO Auto-generated method stub
    super.update(training);
    }
    public List<Training> getAll() {
    // TODO Auto-generated method stub
    DetachedCriteria criteria=DetachedCriteria.forClass(Training.class);
    return super.findByCriteria(criteria);
    }
    public Training get(Serializable id) {
    // TODO Auto-generated method stub
    return (Training) super.get(Training.class, id);
    }
    }
    spring代码三个applicationContext.xml里的
    <bean id="trainingIdAction" class="com.team.ehr.action.TrainAction">
    <property name="trainingService" ref="trainingService"></property>
    </bean>
    <bean id="trainingIdDao" class="com.team.ehr.dao.impl.TrainingDaoImpl">
    <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>
    <bean id="trainingService" class="com.team.ehr.service.impl.TrainingServiceImpl">
    <property name="trainingIdDao" ref="trainingIdDao"></property>
    </bean>
      

  3.   

    你TrainingDaoImpl中没定义trainingIdDao呀？
    private TrainingIdDao trainingIdDao;
    public setTrainingIdDao(TrainingIdDao trainingIdDao) {
        this.trainingIdDao = trainingIdDao;
    }
      

  4.   

    Cannot convert value of type [com.team.ehr.dao.impl.TrainingDaoImpl] to required type [com.team.ehr.dao.TrainingIdDao] for property 'trainingIdDao'不能转换。
