Запуск двух серверов Jetty на том же компьютере

Question

Я создал веб-приложение (с JSP), которое использует конечную точку сервера SOAP для выполнения некоторых операций. Я запускаю оба сервера (WebApp и SOAP-сервер) с gradle jettyEclipseRun, SOAP-сервер на порту 8081 и WebApp на порту 8080. Сначала я запустить сервер SOAP, и когда я бегу WebAPP он бросает следующий исключение (говоря «адрес уже используется»):

BUILD FAILED 

я указал порты в обоих build.gradle файлов. Если я запустил WebApp без использования SOAP-сервера, он работает (хотя он явно не выполняет свои функции). Вот мой SOAP сервер build.gradle:

buildscript { 
    repositories { 
     jcenter() 
    } 

    dependencies { 
     classpath (group: 'com.sahlbach.gradle', name: 'gradle-jetty-eclipse-plugin', version: '1.9.+') 
    } 

} 

apply plugin: 'java' 
apply plugin: 'war' 
apply plugin: 'jettyEclipse' 
apply plugin: 'eclipse' 
apply plugin: 'eclipse-wtp' 


repositories { 
    mavenCentral()            
} 

dependencies { 
    compile "com.sun.xml.ws:jaxws-rt:2.2.8" 
    compile 'com.google.code.gson:gson:2.3' 
} 

jettyEclipse.httpPort = 8081 

Вот мой WebApp build.gradle:

buildscript { 
    repositories { 
     jcenter() 
     mavenCentral() 
    } 

    dependencies { 
     classpath (group: 'com.sahlbach.gradle', name: 'gradle-jetty-eclipse-plugin', version: '1.9.+') 
     classpath 'org.gradle.jacobo.plugins:gradle-wsdl-plugin:1.7.6' 
     classpath 'org.gradle.jacobo.plugins:gradle-jaxb-plugin:1.3.4' 
    } 
}

apply plugin: 'com.github.jacobono.jaxb' 

apply plugin: 'java' 
apply plugin: 'war'

    jaxws "com.sun.xml.ws:jaxws-tools:2.2.8" 
} 

//

wsdl { 
    wsdlFolder = "src/main/wsdl" 
    wsimport { 
    sourceDestinationDirectory = "src-gen/main/java" 
    wsdlLocation = "http://localhost:8081/toDoSOAP?wsdl" 
    } 
} 

sourceSets.main.java.srcDirs += wsdl.wsimport.sourceDestinationDirectory 
compileJava.dependsOn wsimport 

// 
// Required by XJC because toDoSOAP.xsd is a file 
// 

System.setProperty('javax.xml.accessExternalSchema', 'all') 

jettyEclipse.httpPort = 8080 

Может кто-нибудь мне помочь?

Answer 1

Jetty использует два порта: один для обслуживания HTTP-запросов, а другой для остановки причала. Значения по умолчанию 8080 и 8090. Таким образом, вы должны удалить из WebAppbuild.gradle свойство jettyEclipse.httpPort = 8080 (порты являются те, по умолчанию), а затем добавить к SOAP-серверbuild.gradle, например:

jettyEclipse.httpPort=8081 
jettyEclipse.stopPort=8091 

Дополнительная информация об этих свойствах плагина gradle-jetty-eclipse-plugin можно найти здесь: https://github.com/Khoulaiz/gradle-jetty-eclipse-plugin

Я не пробовал, но это имеет смысл для меня.

IMHO Jetty java.net.BindException должен быть более выразительным, предоставляя информацию о конфликтующем порту.

Answer 2

Ошибка

Caused by: java.net.BindException: La dirección ya se está usando 

ака The Address Is Already In Use, означает, что при запуске Jetty, разъем вы указали не удалось связать с конкретным InetSocketAddress (определяется как пара IP + Port).

Самая распространенная причина в том, что что-то еще уже прослушивает этот конкретный InetSocketAddress.
