答案 0 :(得分：1)
只需阅读日志即可。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;
好吧，我们在这里看到AdminContactController需要一个ContactDao的实例。
nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'contactDaoImpl': Injection of persistence dependencies failed;
在这里，日志向我们显示持久性依赖注入失败。
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'CrossfithoornPU' is defined
在您的应用程序上下文中，您设置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>
错误是由持久性单元名称引起的。怎么看persistence.xml？如果需要，请使用persistence.xml更新您的问题。
答案 1 :(得分：0)
首先，你有2个entityManager：在ContactDaoImpl和ServiceImpl中。你只能留下第二个。第二个例外是＆＃34;没有豆名为CrossfithoomPU＆＃34;被定义。将此名称更改为＆＃34; persistenceUnit＆＃34;就像它在你的xml文件中一样。
