Java 如何发送文本消息而不是字节消息

我正在使用blueprint.xml构建一个骆驼路由，该路由与我的JMS队列通信。我一直遇到一些神秘的错误，我的spring boot应用程序充当队列的使用者，它将我的xml作为字节消息而不是文本消息发送，spring使用者对此感到窒息

以下是两条信息，文本一起作用：

我不是唯一一个遇到这种情况的人。

只要在JMS端点上设置选项

jmsMessageType=Text

，告诉Camel使用基于文本的JMS消息即可

请参阅文档：

在发送到JMS端点之前，还可以使用以下命令将消息正文转换为

字符串

：

 <convertBodyTo type="String"/>

是否可以设置github回购协议来演示问题？如果有人能以这种方式帮助你，那就更容易了。请在你的问题中添加你的代码，并附上代码。谢谢@附加ltsallas代码。谢谢我没有看到任何代码，只有XML文件。需要查看您正在使用的代码。

 <convertBodyTo type="String"/>
