tomcat7-maven-plugin：运行多个webapps但端口8080已经在使用中 [英] tomcat7-maven-plugin: run multiple webapps but port 8080 already in use

问题描述

我正在尝试使用 tomcat7-maven-plugin 来设置嵌入式tomcat容器，在 pre-integration-test中运行webapps 阶段，运行集成测试，然后在 post-integration-test 阶段关闭tomcat。该项目是一个多模块maven项目（包含 app1 ， app2 等）。父 pom.xml 如下所示，

I'm trying to use tomcat7-maven-plugin to setup an embedded tomcat container, run webapps in pre-integration-test phase, run integration tests, then shutdown tomcat in post-integration-test phase. The project is a multi-module maven project (contains app1, app2, etc). Parent pom.xml looks like following,

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.tomcat.maven</groupId>
      <artifactId>tomcat7-maven-plugin</artifactId>
      <version>2.1</version>
      <configuration>
        <contextFile>path/to/context.xml</contextFile>
        <tomcatUsers>path/to/tomcat-users.xml</tomcatUsers>
        <fork>true</fork>
      </configuration>
      <executions>
        <execution>
          <id>tomcat-run</id>
          <goals>
            <goal>run</goal>
          </goals>
          <phase>pre-integration-test</phase>
        </execution>
        <execution>
          <id>tomcat-shutdown</id>
          <goals>
            <goal>shutdown</goal>
          </goals>
          <phase>post-integration-test</phase>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

然后我只运行 mvn clean integration-test --projects = app1， APP2 。 当第二个应用开始时，我得到 java.net.BindException ，

Then I just run mvn clean integration-test --projects=app1,app2. When the second app is starting, I get java.net.BindException,

那么在 tomcat7-maven-plugin 中是否有配置在嵌入式tomcat中运行多个webapp？ / p>

So is there a configuration in tomcat7-maven-plugin to run multiple webapps in an embedded tomcat?

推荐答案

参见 tomcat7：run mojo参数：您可以配置插件执行以使用其他端口，类似于此配置：

See tomcat7:run mojo parameters: you can configure plugin executions to use other ports, with something similar to this config:

<execution>
    <id>tomcat-run</id>
    <goals>
        <goal>run</goal>
    </goals>
    <phase>pre-integration-test</phase>
    <configuration>
        <port>9090</port>
    </configuration>
</execution>

当然还要为第二个项目使用另一个端口。

And of course use another port for the second project.
