Smoke logging with Spring java

[courtlanda]

I'm writing a little project, and it's gonna end up like a social network. This is the beginning of work.

Got a class. Contactcontaining information on the person. Interface ContactDAO, to work with the database and test it with the mop ContactSimpleDAO♪ Service interface ContactServise and its implementation ContactManager♪

The whole project is on. https://github.com/SkillsUpCourses/SpringHomeWork/tree/Logging/SpringJavaConfig Trying to finish the logger. Annotations. @AutoLogging above classes which should be logical and written BeanPostProcessor:

public class AutoLoggingBeanPostProcessor implements BeanPostProcessor {
Map<String, Class> 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;
}

}

Spring configurations:

@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<String,Contact> contacts = new HashMap<String, Contact>();
    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<ClearEvent> applicationListener() {
    return new DeleteContactListener();
}

@Bean
public AutoLoggingBeanPostProcessor autologgingBeanPostProcessor() throws Exception {
    return new AutoLoggingBeanPostProcessor();
}

}

Please help me figure this out.

[charlenef]

Anyway, your problem is, you're calling the method. contactBeanFactory inside @Bean- Meta dao()♪ Or that you're a substitute. ContactBeanFactory to proxy AutoLoggingBeanPostProcessorto choose. Get the annotations off. ContactBeanFactory and he'll stop flying.

I don't know, I found this mask on the construction.

Judging by https://jira.spring.io/browse/SPR-6602 ♪ When you did @Configuration♪ getSomethingFactoryBean().getObject() returns different objects every time, which does not coincide with the conduct of xml-configuration. That's why they came up with the challenge. @Bean- the meta returning FactoryBean Explore the result to the result getObject() I returned the bin. Since you've already created a proxy, which is final-grade, you can't do another sub class, and it's falling.
