java - 在同一台机器上运行两个 Jetty 服务器

Question

我创建了一个 Web 应用程序(使用 JSP)，它使用 SOAP 服务器端点来执行一些操作。我使用 gradle jettyEclipseRun 运行两台服务器(WebApp 和 SOAP 服务器)，SOAP 服务器在 8081 端口上运行，WebApp 在 8080 端口上运行。首先，我运行 SOAP 服务器，当我运行 WebApp 时，它会抛出下一个异常(显示“地址已在使用中”):

BUILD FAILED

我已在两个 build.gradle 文件中指定了端口。如果我在不运行 SOAP 服务器的情况下运行 WebApp，它就可以工作(尽管显然它没有履行其功能)。 这是我的 SOAP 服务器 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

这是我的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.wsdl'
apply plugin: 'com.github.jacobono.jaxb'

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


repositories {
   mavenCentral()                                               
}

dependencies {
   providedCompile 'javax.servlet:javax.servlet-api:3.0.1'
   compile 'com.google.code.gson:gson:2.3'
   jaxws "com.sun.xml.ws:jaxws-rt:2.2.8"
   jaxws "com.sun.xml.ws:jaxws-tools:2.2.8"
}

//
// See the documentation of this plugin at
// https://github.com/jacobono/gradle-wsdl-plugin
// 

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

有人可以帮助我吗？

错误

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

又名地址已在使用，意味着在Jetty启动时，您指定的连接器无法绑定(bind)到特定的InetSocketAddress (定义为 IP + 端口对)。

最常见的原因是其他东西已经在监听特定的 InetSocketAddress .
