Spring and @Autowired for ENUM types. Optional

As it is known, in Spring it is impossible to make bins for enumerated types without “crutches” - this type has no constructor.

Caused by: org.springframework.beans.factory.BeanCreationException: Error created bean with name 'demoEnum0' defined in file [... \ DemoEnum0.class]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [ru.itbasis.demo.spring.enums.DemoEnum0]: No default constructor found; nested exception is java.lang.NoSuchMethodException: ru.itbasis.demo.spring.enums.DemoEnum0. <init> ()

In this post I will try to get around this limitation.

Step 1. Replace the factory method

Create an EnumHandlerBeanFactoryPostProcessor class that implements the BeanFactoryPostProcessor interface.

 @Component public class EnumHandlerBeanFactoryPostProcessor implements BeanFactoryPostProcessor { private static final transient Logger LOG = LoggerFactory.getLogger(EnumHandlerBeanFactoryPostProcessor.class.getName()); @Override public void postProcessBeanFactory(final ConfigurableListableBeanFactory beanFactory) throws BeansException { final String[] beanDefinitionNames = beanFactory.getBeanDefinitionNames(); for (String beanDefinitionName : beanDefinitionNames) { final BeanDefinition beanDefinition = beanFactory.getBeanDefinition(beanDefinitionName); LOG.debug("beanDefinitionName: {}", beanDefinitionName); final String beanClassName = beanDefinition.getBeanClassName(); LOG.debug("beanClassName: {}", beanClassName); try { final Class<?> beanClass = Class.forName(beanClassName); if (beanClass.isEnum()) { LOG.trace("found ENUM class: {}", beanClass); LOG.trace("interfaces: {}", beanClass.getInterfaces()); beanDefinition.setFactoryMethodName("values"); } } catch (ClassNotFoundException e) { LOG.error(e.getMessage(), e); } } } } 

Here, in future bins, we look for all classes of type ENUM and replace the factory constructor for them with a call to the “values” method from the bean. Now the result when creating this bean is not an error, but an array of its constants.

But this is not enough - Spring will not allow just to take, and even to slip the created bin, because you cannot get such a bin by its type.
“Well, yes, the disaster is the beginning,” said Ivan the Fool, but he went on to dig further.

Step 2. "Draft" work

“Auburn” our enum-type into the interface and in the tested class we change the type from enum-type to
