如何使用 maven 插件 tomcat7:run with multiple contexts (WARs)? [英] How to use maven plugin tomcat7:run with multiple contexts (WARs)?

问题描述

我一直在使用 mvn tomcat7-maven-plugin:run -am -pl :foo 成功地在 Tomcat 就像在这里显示.现在我想让多个模块在同一个端口但不同的上下文下运行.例如，我想要:

I've been using mvn tomcat7-maven-plugin:run -am -pl :foo successfully to run just a single project at a time in Tomcat like is shown here. Now I'd like to have multiple modules run under the same port but different contexts. For instance, I'd like to have:

/    => foo.war
/bar => bar.war

这是我一直在使用的示例 pom.xml 片段:

Here's an example pom.xml snippet that I've been working with:

<project><!-- ... -->
    <build><!-- ... -->
        <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.apache.tomcat.maven</groupId>
                    <artifactId>tomcat7-maven-plugin</artifactId>
                    <version>2.0-SNAPSHOT</version>
                    <configuration>
                        <path>/</path>
                        <port>8080</port>
                        <addContextWarDependencies>true</addContextWarDependencies>
                        <addWarDependenciesInClassloader>true</addWarDependenciesInClassloader>
                        <warSourceDirectory>${project.build.directory}/${project.build.finalName}/</warSourceDirectory>
                    </configuration>
                    <dependencies>
                        <dependency>
                            <groupId>${project.groupId}</groupId>
                            <artifactId>bar</artifactId>
                            <version>${project.version}</version>
                            <type>war</type>
                            <scope>tomcat</scope>
                        </dependency>
                    </dependencies>
                </plugin>
            </plugins>
        </pluginManagement>
    </build>
    <pluginRepositories>
        <pluginRepository>
            <id>apache.snapshots</id>
            <name>Apache Snapshots</name>
            <url>http://repository.apache.org/content/groups/snapshots-group/</url>
            <releases>
                <enabled>false</enabled>
            </releases>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
        </pluginRepository>
     </pluginRepositories>
</project>

这可以通过 tomcat7-maven-plugin:run 插件实现吗?我正在努力寻找正确的语法来让它发挥良好的作用.当我运行 maven 命令来运行它时，它只运行它在项目层次结构中找到的第一个.如果我使用 <fork>true</fork> 或者显然是从不同的终端运行它们，那么我会得到java.net.BindException:地址已经在使用:8080".

Is this possible with the tomcat7-maven-plugin:run plugin? I'm struggling to find the correct syntax to get it to play well. When I run the maven command to run it, it only runs the first one it finds in the project hierarchy. And if I run them with the <fork>true</fork> or obviously from different terminals then I get "java.net.BindException: Address already in use :8080".

推荐答案

正如已经建议的那样，使用插件配置的 部分，但添加额外的参数 ;true</asWebapp> 对于每个 webapp，即:

As it was already suggested, use <webapps> section of plugin configuration, but add additional parameter <asWebapp>true</asWebapp> for every webapp, i.e:

<webapps> 
  <webapp> 
    <groupId>com.company</groupId> 
    <artifactId>mywebapp</artifactId> 
    <version>1.0</version> 
    <type>war</type>    
    <asWebapp>true</asWebapp> 
  </webapp> 
  <webapp> 
    <groupId>com.company</groupId> 
    <artifactId>mywebapp2</artifactId> 
    <version>2.0</version> 
    <type>war</type>    
    <asWebapp>true</asWebapp> 
  </webapp>
</webapps> 

默认情况下，这些额外的 web 应用程序使用 ${artifactId} 上下文路径进行部署.

These additional webapps are deployed with ${artifactId} context path by default.

当您运行类似 mvn tomcat7:run(在稳定版本 2.0 上尝试)时，看起来如果没有此参数，其他 web 应用程序会被悄悄丢弃.相关的 Jira 问题 表明它是为了向后兼容"而完成的.

It looks like without this parameter additional webapps get silently discarded when you run something like mvn tomcat7:run (tried on stable version 2.0). Related Jira issue tells it was done for "backward compatibility".
