java - Tomcat Freezes deploying SpringBoot App -
i'm trying deply apps (4 spring boot web apps) in tomcat 9 , noticed 2 of them make tomcat log display:
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 and stays way deploying doesn't display deployment finished. thing app works when doens't appear deployed completely. (i see log4j entries , files processed in monitored folder)
these apps monitor 2 different folders using java watchservice following code:
package 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; { try { watchkey watchkey = watchmyservice.take(); (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); { 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); } } if remove do-while apps finished deployed! why? it's standard java watchservice code, me realize i'm missing/what's issue? thing tomcat doesn't deploy 4th app cause keeps deploying 3rd one. in advance help

the tomcat deployer thread seems invoking startmonitoring method. intended, method never returning , hence deployment not getting complete.
to fix this, need run monitoring method in separate (or background) thread.
below refactored example may helpful.
aside note, single instance of watcherservice instances can used watching multiple directories.
