Spring + Hibernate + Maven NoSuchBeanDefinitionException

Question

這個問題是Spring + Hibernate + Maven org.hibernate.MappingException: AnnotationConfiguration instance is required這個演變而來的。

我現在的記錄是：

log4j:WARN No appenders could be found for logger (org.springframework.core.env.StandardEnvironment). 
log4j:WARN Please initialize the log4j system properly. 
Exception in thread "main" org.springframework.beans.factory.BeanCreationException:  Error creating bean with name 'client' defined in class path resource [config.xml]: Cannot resolve reference to bean 'ClientDAOx' while setting bean property 'clientDAO'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'ClientDAOx' is defined

    </beans> 

看來這個問題一直是創建一個DAO的bean。在我的config.xml中添加：default-autowire =「byName」後會發生這種情況。然而，以前有另一個錯誤：

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 

Answer 1

你的bean id爲clientDAO，你是給裁判爲ClientDAO。它應該是大小寫敏感的

<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> 

改變

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