и есть моя конфигурация пружинного servlet.xml
<context:annotation-config />
<context:component-scan base-package="client.controller" />
<context:component-scan base-package="ma" />
<context:component-scan base-package="awb" />
<bean id="jspViewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
и есть мой интерфейс Илог
public interface ILog {
void debug(String msg);
void debug(String msg, Throwable t);
void error(String msg);
void error(String msg, Throwable t);
void fatal(String msg);
void fatal(String msg, Throwable t);
void info(String msg);
void info(String msg, Throwable t);
void warning(String msg);
void warning(String msg, Throwable t);
}
и есть класс, который реализует интерфейс Илог
public class Slf4jLogger implements ILog {
private Logger logger = LoggerFactory.getLogger(Slf4jLogger.class);
public void debug(String msg) {
logger.debug(msg);
}
public void debug(String msg, Throwable t) {
logger.debug(msg, t);
}
public void error(String msg) {
logger.error(msg);
}
public void error(String msg, Throwable t) {
logger.error(msg, t);
}
public void fatal(String msg) {
logger.error("FATAL ERROR:" + msg);
}
public void fatal(String msg, Throwable t) {
logger.error("FATAL ERROR:" + msg, t);
}
public void info(String msg) {
logger.info(msg);
}
public void info(String msg, Throwable t) {
logger.info(msg, t);
}
public void warning(String msg) {
logger.warn(msg);
}
public void warning(String msg, Throwable t) {
logger.warn(msg, t);
}
}
Спасибо'S заранее за помощь.
Вы уверены, что у вас есть компонент, реализующий Илог в контексте? Можете ли вы опубликовать полный стек? –
@leo Я отредактировал сообщение и поместил свой полный стек. – Mouhie
У вас есть класс, который реализует ILog, который создается в качестве весеннего компонента (используя @ Component/@ Service или непосредственно в XML)? – gkamal
