只需读取日志，其清晰。看：

Injection of autowired dependencies failed; 

nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: nl.crossfit.crossfithoorn.dao.ContactDao nl.crossfit.crossfithoorn.controller.admin.AdminContactController.contactDao;

好了，在这里我们看到，AdminContactController需要的ContactDao一个实例。

nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'contactDaoImpl': Injection of persistence dependencies failed;

这里，日志让我们看到注入持久性依赖的失败。

nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'CrossfithoornPU' is defined

在你的应用环境，可以设置persistenceUnit：

<!-- Add JPA support --> 
<bean id="emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" 
     p:persistenceUnitName="persistenceUnit"> 
    <property name="dataSource" ref="dataSource"/> 
    <property name="jpaVendorAdapter"> 
     <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" /> 
    </property> 
</bean>

春uses the specified persistence unit name as the name of the default persistence unit, if applicable and only applied if no external PersistenceUnitManager specified

的错误是由于持久性单元名称。如何看看persistence.xml？如果您需要，请用您的persistence.xml更新您的问题。

非常感谢布鲁诺。我没有注意到ServiceImpl接口。在这个接口中也很明显：@PersistenceContext（unitName =“CrossfithoornPU”） protected EntityManager em; – dragos 2015-02-18 08:28:33

不客气@dragos。如果这有效，请考虑接受答案。 – 2015-02-18 09:13:35

首先，你有2个entityManager：在ContactDaoImpl和ServiceImpl中。你只能留下第二个。第二个例外说“没有名为CrossfithoomPU的bean”被定义。将此名称更改为“persistenceUnit”，因为它在xml文件中。
