Сквозное логирование при помощи Spring java

#java #spring #aop

                    
Пишу небольшой проектик, будет в итоге типа социальной сети. Сейчас самое начало работы. 

Есть класс Contact, содержащий информацию о человеке. Интерфейс ContactDAO, для работы
с базой данных и тестовая его реализация с мапой ContactSimpleDAO. Сервисная прослойка
интерфейс ContactServise и его реализация ContactManager. 

Весь проект есть на Github 
Попыталась допилить логгер. Проставила аннотацию @AutoLogging над классами, методы
которых нужно логировать и написала соответствующий BeanPostProcessor:

public class AutoLoggingBeanPostProcessor implements BeanPostProcessor {

    Map classMap = new HashMap<>();
    private AutoLoggingController loggingController = new AutoLoggingController();
    final Logger logger = LoggerFactory.getLogger(AutoLogging.class);

    public AutoLoggingBeanPostProcessor() throws Exception {
        MBeanServer platformMBeanServer = ManagementFactory.getPlatformMBeanServer();
        platformMBeanServer.registerMBean(loggingController, new ObjectName("autologging",
"name", "autologger"));
    }

    @Override
    public Object postProcessBeforeInitialization(Object bean, String beanName) throws
BeansException {
        Class beanClass = bean.getClass();
        if (beanClass.isAnnotationPresent(AutoLogging.class)) {
            classMap.put(beanName, beanClass);
        }
        return bean;
    }

    @Override
    public Object postProcessAfterInitialization(Object bean, String beanName) throws
BeansException {
        Class beanClass = classMap.get(beanName);
        if (beanClass != null) {
            return Proxy.newProxyInstance(bean.getClass().getClassLoader(), bean.getClass().getInterfaces(),
new InvocationHandler() {

                @Override
                public Object invoke(Object proxy, Method method, Object[] args)
throws Throwable {
                    if (loggingController.isEnabled()) {
                        logger.debug("Call method " + method + " with args: " + Arrays.toString(args));
                        Object result;
                        try {
                            result = method.invoke(bean, args);
                            logger.debug("Method " + method + " returns " + result);
                            return result;
                        } catch (Exception e) {
                            logger.error("Method " + method + "threw Exception ", e);
                            throw e;
                        }
                    } else {
                        return method.invoke(bean, args);
                    }
                }
            });
        }
        return bean;
    }
}


Спринговые конфигурации:

@Configuration
@PropertySource("classpath:ContactBookMaximumSize.properties")
@PropertySource("classpath:contacts.properties")
@ComponentScan(basePackages = {"com.stoxa.springjavaconfig.*"},
    nameGenerator = KsushikBeanNameGenerator.class)
public class AppConfig {
    @Bean
    public ContactBeanFactory contactBeanFactory() {
        return new ContactBeanFactory();
    }

    @Bean
    public static PropertySourcesPlaceholderConfigurer configurer() {
    return new PropertySourcesPlaceholderConfigurer();
    }

    @Value("${maxSize}")
    private int maxContactBookSize;

    @Bean
    public ContactDAO dao() throws Exception {
        final ContactSimpleDAO dao = new ContactSimpleDAO();
        Map contacts = new HashMap();
        contacts.put(contactBeanFactory().getObject().getPhone(),contactBeanFactory().getObject());
        contacts.put(contactBeanFactory().getObject().getPhone(),contactBeanFactory().getObject());
        contacts.put(contactBeanFactory().getObject().getPhone(),contactBeanFactory().getObject());
        contacts.put(contactBeanFactory().getObject().getPhone(),contactBeanFactory().getObject());
        contacts.put(contactBeanFactory().getObject().getPhone(),contactBeanFactory().getObject());
        dao.setContacts(contacts);
        return dao;
    }

    @Bean(initMethod = "init")
    public ContactService contactService() throws Exception {
        ContactManager contactService = new ContactManager();
        contactService.setDao(dao());
        contactService.setMaxContactBookSize(maxContactBookSize);
        return contactService;
    }

    @Bean
    public ApplicationEventPublisherAware applicationEventPublisherAware() {
        return new ContactManager();
    }

    @Bean
    ApplicationListener applicationListener() {
        return new DeleteContactListener();
    }

    @Bean
    public AutoLoggingBeanPostProcessor autologgingBeanPostProcessor() throws Exception {

Пожалуйста, помогите разобраться.
    

Ответы

Ответ 1

В общем, ваша проблема в том, что вы вызываете метод contactBeanFactory внутри @Bean-метода
dao(). Или в том, что вы подменяете ContactBeanFactory на прокси в своем AutoLoggingBeanPostProcessor,
на выбор. Уберите аннотацию с ContactBeanFactory и вылетать перестанет.

Как сделать сквозное логирование в FactoryBean'е с вашей конфигурацией - не знаю,
я эту маску на стройке нашел.

Судя по SPR-6602, когда делали @Configuration, столкнулись с тем, что getSomethingFactoryBean().getObject()
возвращает каждый раз разные объекты, что не совпадало с поведением xml-конфигурации.
Поэтому придумали при вызове @Bean-метода, возвращающего FactoryBean проксировать результат,
чтобы его getObject() возвращал кэшированый бин. Поскольку вы уже создали прокси, который
является final-подклассом, сделать еще один подкласс нельзя, и все падает.


Ответ 2

Обратите внимание на вашу конфигурацию: при создании бина ContactDAO, вам требуется
бин ContactBeanFactory. Вы пытаетесь получить его, вызвав метод contactBeanFactory().
В данном случае, при вызове метода contactBeanFactory(), вы не получите проинициализированный
бин из контекста спринга, а будете получать новый объект на каждый вызов метода.
Вероятно, следующие поправки в конфигурации решат вашу проблему:  

    @Bean
    public ContactDAO dao(ContactBeanFactory contactBeanfactory) throws Exception {
    final ContactSimpleDAO dao = new ContactSimpleDAO();
    Map contacts = new HashMap();
    contacts.put(contactBeanFactory.getObject().getPhone(),contactBeanFactory.getObject());
    contacts.put(contactBeanFactory.getObject().getPhone(),contactBeanFactory.getObject());
    contacts.put(contactBeanFactory.getObject().getPhone(),contactBeanFactory.getObject());
    contacts.put(contactBeanFactory.getObject().getPhone(),contactBeanFactory.getObject());
    contacts.put(contactBeanFactory.getObject().getPhone(),contactBeanFactory.getObject());
    dao.setContacts(contacts);
    return dao;
    }  

    @Bean(initMethod = "init")
    public ContactService contactService(ContactDAO contactDAO) throws Exception {
    ContactManager contactService = new ContactManager();
    contactService.setDao(contactDAO);
    contactService.setMaxContactBookSize(maxContactBookSize);
    return contactService;
    }
