java - 在 Anypoint Studio (MuleSoft) 中发送电子邮件时出错

Question

每次我尝试在 AnyPoint Studio 中发送电子邮件时，都会收到错误消息。我尝试过从其他计算机发送它，它总是有效。它似乎对我不起作用，我不知道为什么。

这是我的 .xml:

<?xml version="1.0" encoding="UTF-8"?>
<mule xmlns:smtp="http://www.mulesoft.org/schema/mule/smtp" xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"
    xmlns:spring="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <smtp:gmail-connector name="Gmail" validateConnections="true" doc:name="Gmail"/>
    <flow name="attemptsendemailFlow">
        <http:listener config-ref="HTTP_Listener_Configuration" path="/sendemail" doc:name="HTTP"/>
        <set-payload value="Hello" doc:name="Set Payload"/>
        <smtp:outbound-endpoint host="smtp.gmail.com"  user="myemail@gmail.com" password="mypwd" connector-ref="Gmail" to="myemail@gmail.com" from="myemail@gmail.com" subject="This is a test." responseTimeout="10000" doc:name="SMTP"/>
    </flow>
</mule>

当我打开浏览器并输入 localhost:8081/sendemail 时，不会发送电子邮件，浏览器会打印此消息。

Failed to route event via endpoint: DefaultOutboundEndpoint{endpointUri=smtp://myemail%40gmail.com:<password>@smtp.gmail.com, connector=GmailSmtpConnector

}
,  name='endpoint.smtp.myemail.gmail.com', mep=ONE_WAY, properties={fromAddress=myemail@gmail.com, toAddresses=myemail@gmail.com, subject=This is a test.}, transactionConfig=Transaction{factory=null, action=INDIFFERENT, timeout=0}, deleteUnacceptedMessages=false, initialState=started, responseTimeout=10000, endpointEncoding=UTF-8, disableTransportTransformer=false}.

有趣的是，我在其他计算机上测试了完全相同的 xml 并且它有效。

我会首先测试您的计算机是否可以连接到 Gmail 服务器。

尝试“telnet smtp.gmail.com 587”或 Mac 等效项。
