Dynamic context - autowiring - spring

Question

I am dynamically adding contexts to the application context with the following code:
#Component
#Scope("singleton")
public class DynamicContextLoader implements ApplicationContextAware {
private static ApplicationContext context;
private Map<String, InterfacePropertyDto> contextMap;
#Autowired
IJpaDao jpaDao;
#PostConstruct
public void init() {
contextMap = (Map<String, InterfacePropertyDto>) context.getBean("contextMap");
contextMap.forEach((contextName, property) -> {
String p = jpaDao.getProperty(property.getPropertyName(), property.getPropertyType());
if (p != null) {
ConfigurableApplicationContext ctx = new ClassPathXmlApplicationContext(
new String[]{"/META-INF/spring/integration/" + contextName},
false, context);
ctx.refresh();
}
});
}
#Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
context = applicationContext;
}
}
This works well and all the beans defined in the new context are created. However the #Autowired does not work for any of these new beans.
For example a bean defined in the new context as:
<bean id="outboundContractJdbcFileMapper" class="com.......integration.model.contract.ContractMapper"/>
has the following autowiring:
public class ContractMapper implements RowMapper<ContractFile> {
#Autowired
IIntegrationDao integrationDao;
#Override
public ContractFile mapRow(ResultSet rs, int rowNum) throws SQLException {
......
}
}
At runtime the outboundContractJdbcFileMapper property integrationDao is null.
Is there a way to force the autowiring to occur when the beans are created? I was hoping that ctx.refresh() would do this.

That doesn't work automatically for the ClassPathXmlApplicationContext. You have to add <context:annotation-config/> to that child context as well:
<xsd:element name="annotation-config">
<xsd:annotation>
<xsd:documentation><![CDATA[
Activates various annotations to be detected in bean classes: Spring's #Required and
#Autowired, as well as JSR 250's #PostConstruct, #PreDestroy and #Resource (if available),
JAX-WS's #WebServiceRef (if available), EJB 3's #EJB (if available), and JPA's
#PersistenceContext and #PersistenceUnit (if available). Alternatively, you may
choose to activate the individual BeanPostProcessors for those annotations.
Note: This tag does not activate processing of Spring's #Transactional or EJB 3's
#TransactionAttribute annotation. Consider the use of the <tx:annotation-driven>
tag for that purpose.
See javadoc for org.springframework.context.annotation.AnnotationConfigApplicationContext
for information on code-based alternatives to bootstrapping annotation-driven support.
