Java apache commons覆盖的端口和主机

我创建了一个EclipseMaven项目，该项目将在Activti bpm中启动一个serviceTask，向给定用户发送电子邮件

我使用的是ApacheJames服务器，并将其配置为gmail，我可以通过telnet发送电子邮件，但不能使用我的服务任务

问题是我的配置被apache commons中名为Email的类覆盖。 我不明白为什么要调用这个类，我在java代码中没有使用apache.commons

James配置：config.xml

    <servernames autodetect="true" autodetectIP="true">
    <servername>smtp.gmail.com</servername>
    </servernames>

    <dnsserver>
    <servers>
    <!--Enter ip address of your DNS server, one IP address per server -->
    <!-- element. -->
    <!--
    <server>127.0.0.1</server>
    -->
    <server> 8.8.8.8 </server>
    <server> 8.8.4.4 </server>
    </servers>
    <!-- Change autodiscover to false if you would like to turn off autodiscovery -->
    <!-- and set the DNS servers manually in the <servers> section -->
    <autodiscover>true</autodiscover>
    <authoritative>false</authoritative>

    <!-- Maximum number of entries to maintain in the DNS cache -->
    <maxcachesize>50000</maxcachesize>
    </dnsserver>

这是activiti.cfg.xml文件：

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="processEngineConfiguration"       
    class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration" >
    <!-- Database configurations -->
    <property name="databaseType" value="h2" />
    <property name="jdbcUrl
    value="jdbc:h2:C:/Users/Alexandra/tmp/activiti;AUTO_SERVER=TRUE" />
    <property name="jdbcDriver" value="org.h2.Driver" />
    <property name="jdbcUsername" value="sa" />
    <property name="jdbcPassword" value="" />

    <!-- Database configurations -->
    <property name="databaseSchemaUpdate" value="true" />

    <!-- job executor configurations -->
    <property name="jobExecutorActivate" value="true" />

    <!-- mail server configurations -->
    <property name="mailServerHost" value="smtp.gmail.com" />
    <property name="mailServerPort" value="587" />
    <property name="mailServerUsername" value="root" />
    <property name="mailServerPassword" value="root" />

    <property name="history" value="full" />

    <property name="customPostDeployers">
    <list>
    <bean class="org.activiti.engine.impl.rules.RulesDeployer" />
    </list>
    </property>

    </bean>

</beans>

这个问题现在已经解决了。我通过设置流程引擎的数据解决了这个问题

     ProcessEngine processEngine = ProcessEngineConfiguration
     .createStandaloneInMemProcessEngineConfiguration()
     .setMailServerHost("smtp.gmail.com")
     .setMailServerPort(587)
     .setMailServerUsername("root")
     .setMailServerPassword("root")
     .setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE)
     .setMailServerUseSSL(true)
     .setMailServerUseTLS(true)
     .setMailServerDefaultFrom("workflowact@gmail.com")
     .buildProcessEngine();

发布您的电子邮件代码，您可能还想检查James是如何配置的，因为它确实使用apache.commons（作为apache项目）。我现在已经添加了代码，希望您能够提供帮助：）
    // Create Activiti process engine
    ProcessEngine processEngine = ProcessEngineConfiguration
    .createStandaloneInMemProcessEngineConfiguration()
    .buildProcessEngine();

    // Get Activiti services
    RepositoryService repositoryService = processEngine.getRepositoryService();
    RuntimeService runtimeService = processEngine.getRuntimeService();

    // Deploy the process definition
    repositoryService.createDeployment()
    .addClasspathResource("risk.bpmn20.xml")
    .deploy();


    // Start a process instance
    String procId =  
    runtimeService.startProcessInstanceByKey("EmailNotification").getId();
