问题
I am trying to integrate SDN with my spring-hibernate app. With minimal <neo4j:config> and <neo4j:repositories> configuration, it works fine. But when i include either @Neo4jTransactional or write a custom transactionManager i get an infinite loop in creating nodeEntityStateFactory bean in the intercept method in ConfigurationClassEnhancer class. Here is the exception i get.
java.lang.IllegalStateException: Singleton 'nodeEntityStateFactory' isn't currently in creation
Here is the intercept method.
public Object intercept(Object enhancedConfigInstance, Method beanMethod, Object[] beanMethodArgs,
MethodProxy cglibMethodProxy) throws Throwable {
String beanName = BeanAnnotationHelper.determineBeanNameFor(beanMethod);
Scope scope = AnnotationUtils.findAnnotation(beanMethod, Scope.class);
if (scope != null && scope.proxyMode() != ScopedProxyMode.NO) {
String scopedBeanName = ScopedProxyCreator.getTargetBeanName(beanName);
if (this.beanFactory.isCurrentlyInCreation(scopedBeanName)) {
beanName = scopedBeanName;
}
}
if (factoryContainsBean('&'+beanName) && factoryContainsBean(beanName)) {
Object factoryBean = this.beanFactory.getBean('&'+beanName);
if (factoryBean instanceof ScopedProxyFactoryBean) {
}
else {
return enhanceFactoryBean(factoryBean.getClass(), beanName);
}
}
boolean factoryIsCaller = beanMethod.equals(SimpleInstantiationStrategy.getCurrentlyInvokedFactoryMethod());
boolean factoryAlreadyContainsSingleton = this.beanFactory.containsSingleton(beanName);
if (factoryIsCaller && !factoryAlreadyContainsSingleton) {
if (BeanFactoryPostProcessor.class.isAssignableFrom(beanMethod.getReturnType())) {
logger.warn(String.format("@Bean method %s.%s is non-static and returns an object " +
"assignable to Spring's BeanFactoryPostProcessor interface. This will " +
"result in a failure to process annotations such as @Autowired, " +
"@Resource and @PostConstruct within the method's declaring " +
"@Configuration class. Add the 'static' modifier to this method to avoid " +
"these container lifecycle issues; see @Bean Javadoc for complete details",
beanMethod.getDeclaringClass().getSimpleName(), beanMethod.getName()));
}
//This doesn't invoke the @bean annotated constructor which it should. Instead it comes back to the method.
return cglibMethodProxy.invokeSuper(enhancedConfigInstance, beanMethodArgs);
}
else {
boolean alreadyInCreation = this.beanFactory.isCurrentlyInCreation(beanName);
try {
if (alreadyInCreation) {
this.beanFactory.setCurrentlyInCreation(beanName, false);
}
return this.beanFactory.getBean(beanName);
} finally {
if (alreadyInCreation) {
this.beanFactory.setCurrentlyInCreation(beanName, true);
}
}
}
}
say, i am using TM for two methods.
I have two methods
@Transactional
methodA(){} // access using entityManager (hibernate)
@Neo4jTransactional
methodB(){} // access using entityRepository interface (SDN)
Even if i try using the ChainedTransactionManager and annotate methodB with @Transactional, the same error occurs. Thanks in advance.
