xml - NoSuchBeanDefinitionException caused by nested bean definition for Spring JPA -


spring jpa 4.2.1

nested bean definition looks below gets nosuchbeandefinitionexception:

"no qualifying bean of type [javax.persistence.entitymanagerfactory] defined"

<bean id="tm" class="...jpatransactionmanager">     <property name="entitymanagerfactory">         <bean class="...localcontainerentitymanagerfactorybean">             <property name="datasource">                 <bean class="...basicdatasource"                     p:driverclassname="..." p:url="...">                 </bean>             </property>         </bean>     </property> </bean>

only flat definition works below, why?

<bean id="tm" class="...jpatransactionmanager">     <property name="entitymanagerfactory" ref="emf" /> </bean> <bean id="emf" class="...localcontainerentitymanagerfactorybean">     <property name="datasource" ref="ds" /> </bean> <bean id="ds" class="...basicdatasource"     p:driverclassname="..." p:url="..."> </bean>

some other bean requires entitymanagerfactory (which one, can't - didn't show full stack trace). , inner beans anonymous , can't retrieved using beanfactory.getbean() or @autowired, that's why error in first case.

inner beans always anonymous , always created outer bean. not possible inject inner beans collaborating beans other enclosing bean.

in second case entitymanagerfactorybean not inner bean , can used other bean.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
