Was könnte ein Grund für diese Ausnahme sein?

Answer 1

Try OpenEntityManagerInViewFilter von Frühling in Ihrem web.xml Zugabe

<filter> 
<filter-name>hibernateFilter</filter-name> 
<filter-class> 
    org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class> 
<init-param> 
    <param-name>entityManagerFactoryBeanName</param-name> 
    <param-value>entityManagerFactory</param-value> 
</init-param> 
</filter> 
<filter-mapping> 
    <filter-name>hibernateFilter</filter-name> 
    <url-pattern>/services/*</url-pattern> 
</filter-mapping>
