我正在尝试从我的代理服务发送和发送电子邮件。电子邮件已发送但仅附件。邮件正文未发送。我的要求是在附件中发送包含正文和错误详细信息的电子邮件。
我的代理代码是：

第一个参数是Error附件，第二个参数是body。目前它正在发送带有两个参数的附件。
答案 0 :(得分：2)
在分析了WSO2 ESB的内部代码之后，我发现当我们尝试发送多部分消息时，WSO2已经放置了硬编码字符串（Web服务附件）消息。如果您想要自定义消息，请编辑源代码并重新编译jar。
你可以在{WSO2 ESB_HOME}/repository/components/patches/patch000x/axis2_1.6.1.wso2v10.jar.找到相应的罐子
（上述路径特定于WSO2 ESB 4.8.0）
在这个罐子里转到/org/apache/axis2/transport/mail/MailTransportSender.java。编辑此文件并在上面的位置替换修补的jar。
以下是sendEmail函数的代码:(带****的消息是我的自定义消息）
