Spring + Hibernate + Maven NoSuchBeanDefinitionException [英] Spring + Hibernate + Maven NoSuchBeanDefinitionException

问题描述

这个问题是一个演化的春天+休眠+ Maven的 org.hibernate.MappingException：需要AnnotationConfiguration实例。

我当前的日志是：

看来问题总是在创建一个DAO bean。在我的config.xml中添加：default-autowire =byName后会发生这种情况。然而之前还有一个错误：

 创建名为'clientDAOImpl'的bean时出错[C：\Users\ Странник\workspace\aktorstask\target\classes\ee\st\running\dao\ClientDAOImpl.class]：调用init方法失败;嵌套异常是java.lang.IllegalArgumentException：'sessionFactory'或'hibernateTemplate'是必需的
  

解决方案

您的bean id是 clientDAO ，并且您将ref指定为 ClientDAO 。它应该区分大小写

 < bean id =clientclass =ee.st.running.model.Client > 
< property name =clientDAOref =ClientDAO>< / property> //这是问题。 
< / bean> 
 
< bean id =clientDAOclass =ee.st.running.dao.ClientDAOImpl> 
< property name =sessionFactoryref =sessionFactory>< / property> 
< / bean> 
  

更改后

 < bean id =clientclass =ee.st.running.model.Client> 
< property name =clientDAOref =ClientDAO>< / property> //这是问题。 
< / bean> 
  

This question is an evolution of Spring + Hibernate + Maven org.hibernate.MappingException: AnnotationConfiguration instance is required that.

My current log is:

      <bean id = "orderDAO" class = "ee.st.running.dao.OrderDAOImpl">

  </beans>

It seems that the problem is always in creating a DAO bean. That occurs after adding: default-autowire="byName" in my config.xml. Yet previously there was another error:

Error creating bean with name 'clientDAOImpl' defined in file [C:\Users\Странник\workspace\aktorstask\target\classes\ee\st\running\dao\ClientDAOImpl.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: 'sessionFactory' or 'hibernateTemplate' is required

解决方案

Your bean id is clientDAO and you are giving ref as ClientDAO. It should be case sensitive

  <bean id = "client" class = "ee.st.running.model.Client">
  <property name="clientDAO" ref = "ClientDAO"></property> //Here is the problem.
  </bean>

  <bean id = "clientDAO" class = "ee.st.running.dao.ClientDAOImpl">
  <property name="sessionFactory" ref = "sessionFactory"></property>
  </bean>

After changing

  <bean id = "client" class = "ee.st.running.model.Client">
  <property name="clientDAO" ref = "ClientDAO"></property> //Here is the problem.
  </bean>
