Tri*_*ick 3 java spring request listener
我的监听器正在填充Cache(Terracota),如果在应用程序启动时出现问题,则抛出ExceptionInInitializerError.我想获取服务器名称(如在HttpServletRequest - getServerName()上)以了解这发生的位置.
我怎么才能得到这个信息?
import javax.servlet.ServletContextEvent;
import net.f.core.service.util.CacheUtil;
import org.apache.log4j.Logger;
import org.springframework.web.context.ContextLoaderListener;
/**
* Application Lifecycle Listener implementation class OnContextLoadListener
*
*/
public class OnContextLoadListener extends ContextLoaderListener {
private static final Logger log = Logger
.getLogger(OnContextLoadListener.class);
@Override
public void contextDestroyed(
@SuppressWarnings("unused") ServletContextEvent sce) {
// nothing here
}
@Override
public void contextInitialized(
@SuppressWarnings("unused") ServletContextEvent sce) {
try {
CacheUtil.getInstance();
} catch (ExceptionInInitializerError e) {
log.error("Problem with application start!", e);
// notify me
}
}

服务器主机名是请求的一部分,因为它取决于客户端用于访问主机的URL.
如果您对本地主机名感兴趣,可以尝试:
String hostname = InetAddress.getLocalHost().getHostName();
