在同一台计算机上运行两个Jetty服务器

标签： java web-services soap gradle jetty

我创建了一个Web应用程序（使用JSP），它使用SOAP服务器端点来执行某些操作。我使用 gradle jettyEclipseRun 运行两个服务器（WebApp和SOAP服务器），8081端口上的SOAP服务器和8080端口上的WebApp。首先我运行SOAP服务器，当我运行WebApp时，它抛出下一个异常（说“地址已经在使用中”）：

BUILD FAILED

我在 build.gradle 文件中都指定了端口。如果我在没有运行SOAP服务器的情况下运行WebApp，它就可以工作（尽管它显然没有完成其功能）。 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.+')

jettyEclipse.httpPort = 8080

任何人都可以帮助我吗？

2 个答案:

答案 0 :(得分：3)

错误

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

aka The Address Is Already In Use，表示在启动Jetty时，您指定的连接器无法绑定到特定的InetSocketAddress（定义为IP +端口对）。

最常见的原因是其他内容已经在监听特定的InetSocketAddress。

答案 1 :(得分：1)

Jetty使用两个端口：一个用于提供HTTP请求，另一个用于停止jetty。默认值为8080和8090.因此，您应该从 WebApp build.gradle中删除属性jettyEclipse.httpPort = 8080（端口是默认值），然后添加到 SOAP服务器 build.gradle例如：

jettyEclipse.httpPort=8081
jettyEclipse.stopPort=8091

有关gradle-jetty-eclipse-plugin的这些属性的更多信息，请访问：https://github.com/Khoulaiz/gradle-jetty-eclipse-plugin

我没试过，但对我来说很有意义。

通过提供有关哪个是冲突端口的信息，恕我直言Jetty java.net.BindException应该更具表现力。
