[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-1584) @Logger and Spring beans

@Logger and Spring beans ------------------------ Key: JBSEAM-1584 URL: http://jira.jboss.com/jira/browse/JBSEAM-1584 Project: JBoss Seam Issue Type: Feature Request Components: Spring Affects Versions: 2.0.0.BETA1 Reporter: Magnus Heino Assigned To: Michael Youngstrom It would be nice if spring beans could be scanned for @Logger and injected with Log instances just like seam components. Using the code below, you can add this to applicationContext.xml... <bean class="org.jboss.seam.ioc.spring.LoggerPostProcessor" /> ...to have all spring beans scanned for @Logger and have a Log instance injected, just like seam components. Then you can access the same context and log functionallity in your spring beans as in your seam components. I guess the seam spring namespace could be extended with <seam:logger/> to make it even more simple to use. package org.jboss.seam.ioc.spring; import java.lang.reflect.Field; import org.jboss.seam.annotations.Logger; import org.jboss.seam.log.Logging; import org.springframework.beans.BeansException; import org.springframework.beans.factory.config.BeanPostProcessor; import org.springframework.util.ReflectionUtils; import org.springframework.util.StringUtils; import org.springframework.util.ReflectionUtils.FieldCallback; public class LoggerPostProcessor implements BeanPostProcessor { public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException { return bean; } public Object postProcessBeforeInitialization(final Object bean, final String beanName) throws BeansException { ReflectionUtils.doWithFields(bean.getClass(), new FieldCallback() { public void doWith(Field field) throws IllegalArgumentException, IllegalAccessException { if (field.isAnnotationPresent(Logger.class)) { String category = field.getAnnotation(Logger.class).value(); if(!StringUtils.hasText(category)) { category = bean.getClass().getName(); } ReflectionUtils.makeAccessible(field); field.set(bean, Logging.getLog(category)); } } }); return bean; } }
