在 Tomcat 中发送带有附件文件的消息时缺少起始边界异常 [英] Missing start boundary Exception when sending messages with an attachment file in Tomcat
问题描述
我找到了许多可能与此问题匹配的方法，但没有一个对我有用.
I've found a number of possible matches to this problem but none that work for me.
我正在使用 Apache Camel 将文件作为电子邮件附件发送.它使用以下 Maven 目标完美运行:
I'm using Apache Camel to deliver a file as an email attachement. It works perfectly using the following maven goals:
码头:运行码头:运行爆炸码头:跑战
jetty:run jetty:run-exploded jetty:run-war
我使用的是 Java 1.6.我的部署容器是 tomcat6.在 tomcat6 和 tomcat7 中，我得到以下异常:
I'm using java 1.6. My deployment container is tomcat6. In tomcat6 and tomcat7 I get the following exception:
org.springframework.mail.MailSendException:失败的消息:javax.mail.MessagingException:缺少起始边界；消息异常详细信息 (1) 是:失败消息 1:javax.mail.MessagingException:缺少起始边界在 javax.mail.internet.MimeMultipart.parsebm(MimeMultipart.java:882)
org.springframework.mail.MailSendException: Failed messages: javax.mail.MessagingException: Missing start boundary; message exception details (1) are: Failed message 1: javax.mail.MessagingException: Missing start boundary at javax.mail.internet.MimeMultipart.parsebm(MimeMultipart.java:882)
网络上的建议表明这是一个类加载器问题.要么是没有找到activation-1.1.jar或者mail-1.4.4.jar文件，要么就是没有找到mail-1.4.4.jar中的mailcap文件.
The advice on the web suggests this is a class loader problem. Its either that the activation-1.1.jar or mail-1.4.4.jar files are not being found, or the mailcap file in mail-1.4.4.jar is not being found.
我已经尝试将这些 jar 文件放在 tomcat/lib 中.我已经尝试将 jar 文件中的 mailcap 复制到爆炸战争的 META-INF 目录中.这些都没有区别.
I've tried putting these jar files in tomcat/lib. I've tried copying the mailcap from the jar file into the META-INF directory of the exploded war. Neither of these make a difference.
版本:
Windows:Apache Tomcat/7.0.5 JDK 1.6.0_27-b07 Apache Camel 2.8.0-fuse-00-08
Windows: Apache Tomcat/7.0.5 JDK 1.6.0_27-b07 Apache Camel 2.8.0-fuse-00-08
Linux - ubuntu 10.04 LTS 附带的版本 - 我稍后会检查这些并添加.
Linux - the versions that come with ubuntu 10.04 LTS - I'll check these later and add.
这是我的骆驼路线的简化版:
This is a simplified version of my camel routes:
<route id="uploadFileForm">
<from uri="jetty:http://0.0.0.0:9095/premier"/>
<to uri="velocity:form.html"/>
</route>
<route id="uploadFile">
<from uri="jetty:http://0.0.0.0:9095/fup"/>
<to uri="log:mail?showBody=true&showHeaders=true"/>
<to uri="smtp://localhost"/>
<setHeader headerName="content-type"><constant>text/plain</constant></setHeader>
<setBody><constant>Message Sent</constant></setBody>
</route>
这是日志显示的内容:

一个最小的Maven 项目示例是这里，战争是此处.如果你在 eclipse 中运行项目或者使用
A minimal example maven project is here and the war is here. If you run the project in eclipse or with
mvn jetty:run
然后使用 http://localhost:9095/premier
您将收到无法联系服务器"异常.但是，如果您将战争部署到 tomcat，您将获得缺少的开始边界异常.如果您编辑 applicationContext.xml 并将 ** 替换为有效值，它实际上会发送一封电子邮件.
You will get a "cannot contact server" exception. But if you deploy the war to tomcat you will get the missing start boundary exception. If you edit applicationContext.xml and replace the ** with valid values, it will actually send an email.
有什么想法吗?
推荐答案
我已经尝试了你的简化骆驼路线示例，它与 mvn jetty:run 配合得很好.
I have tried your simplified camel route sample, it works well with mvn jetty:run.
在我的 Tomcat 7.0.27、Java 6 中，它确实可以工作.邮件已正确发送.唯一的区别是我不使用:
In my Tomcat 7.0.27, Java 6, it actually works. The mail was sent correctly. The only difference is I don't use the:
mvn install
改为使用:
mvn package
然后将target/test-mail-0.0.1-SNAPSHOT.war复制到Tomcat webapps文件夹下，启动tomcat(bin/startup.sh或者bin/startup.bat)
Then copy the target/test-mail-0.0.1-SNAPSHOT.war to the Tomcat webapps folder, and start tomcat (bin/startup.sh or bin/startup.bat).
希望这也适用于您.
我的建议是您选择与我相同的 Tomcat 版本并执行相同的步骤.
My suggestion that you pick the same Tomcat version as I had and follow the same step.
您应该的其他问题来源:
Other source of problem you should:
- 检查您是否将环境变量 CATALINA_HOME 或 CATALINA_BASE 设置为指向其他 Tomcat 安装.
- 同样在环境变量中，检查您的 JRE_HOME 或 JAVA_HOME(使用 JDK 时)的内容，以及您的 CLASSPATH 变量.您应该将类路径设置为 $JAVA_HOME/jre/lib:$JAVA_HOME/jre/lib/ext:.或 %JAVA_HOME%/jre/lib;%JAVA_HOME%/jre/lib/ext;.(最后一个点很重要)
- 如果您仅在 JRE 上运行，请将 JAVA_HOME/lib 替换为 JRE_HOME.
- 您运行的是哪个版本的 JVM.我使用的是 Oracle JDK 6.您使用的是 OpenJDK/J9 还是其他?
