我正在尝试在Tomcat 9中使用某些应用程序(4个春季启动Web应用程序),我注意到其中2个使Tomcat日志显示:
17-Nov-2016 00:15:07.110 INFO [localhost-startStop-2] org.apache.catalina.startup.HostConfig.deployWAR Deploying web application archive /Users/viruskimera/apache-tomcat-9.0.0.M11/webapps/ftpoutbound990-0.0.1-SNAPSHOT.war
而且它保持这种状态,只是部署它不会显示DEPLOYMENT FINISHED。
事实是,即使应用程序并未完全部署,它也能正常工作。
(我看到我的log4j条目和文件在受监视的文件夹中处理)
这些应用程序使用Java watchService通过以下代码监视2个不同的文件夹:
包com.ftpoutbound990.monitor;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.nio.file.ClosedWatchServiceException;
import java.nio.file.FileSystems;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.StandardWatchEventKinds;
import java.nio.file.WatchEvent;
import java.nio.file.WatchKey;
import java.nio.file.WatchService;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
import com.ftpoutbound990.client.FtpoutboundApp;
@Component
public class MonitorDirectory {
final static Logger logger = Logger.getLogger(MonitorDirectory.class);
@Autowired
private FtpoutboundApp ftpoutboundapp;
@Value("${folder990}")
private String folder990;
public void startMonitoring() throws IOException, InterruptedException {
logger.info("INICIO DE MONITOREO DE ARCHIVOS 990");
try (WatchService watchService = FileSystems.getDefault().newWatchService()) {
Path faxFolder = Paths.get(folder990);
WatchService watchmyservice = FileSystems.getDefault().newWatchService();
faxFolder.register(watchmyservice, StandardWatchEventKinds.ENTRY_CREATE);
boolean valid = true;
do {
try {
WatchKey watchKey = watchmyservice.take();
for (WatchEvent event : watchKey.pollEvents()) {
WatchEvent.Kind kind = event.kind();
if (StandardWatchEventKinds.ENTRY_CREATE.equals(event.kind())) {
String fileName = event.context().toString();
logger.info("ARCHIVO NUEVO:" + fileName);
boolean isGrowing = false;
Long initialWeight = new Long(0);
Long finalWeight = new Long(0);
Path child = faxFolder.resolve(folder990 + fileName);
do {
initialWeight = child.toFile().length();
Thread.sleep(1000);
finalWeight = child.toFile().length();
isGrowing = initialWeight < finalWeight;
logger.info("AUN COPIANDO ARCHIVO:" + fileName);
} while (isGrowing);
logger.info("LISTO ARCHIVO:" + fileName);
getFile(fileName);
}
}
valid = watchKey.reset();
// Thread.sleep(1000 * 10);
} catch (InterruptedException | ClosedWatchServiceException e) {
//watchmyservice.close();
Thread.currentThread().interrupt();
}
} while (valid);
}
}
public void getFile(String fileName) throws IOException {
File file = new File(folder990 + fileName);
ftpoutboundapp.createGateway(file);
}
}
如果我删除Do-While,则应用程序会完成部署!但为什么?这是标准的Java监视服务代码,有人可以帮助我认识到我所缺少的内容吗?
事实是,Tomcat没有部署我的第4个应用程序,因为它一直在部署第3个应用程序。
在此先感谢您的帮助

最佳答案
在盲人手中射击。
对代码的简单回顾表明,如果在try catch中引发异常,则布尔标志valid
仍为true
,从而导致无限循环。
因此,在catch
块的主体中将标志设置为false!
