使用Mule CE 3.5.0中的java发送电子邮件
我正在尝试使用java
我遇到的问题在Mule CE中发送电子邮件:
1我想从这个json
文件https://gist.githubusercontent.com/Rajeun/b550fe17181610f5c0f0/raw/934bf1e621d6bc056f20dee653dac74275026ba5/file.json“我不知道怎么做”中获取收件人的电子邮件
2在我发布我的尝试下:
Xml文件:
<flow name="cronsFlow2" >
<quartz:inbound-endpoint responseTimeout="10000" doc:name="Quartz" jobName="HTTP-Puller-Scheduler" repeatInterval="5000" repeatCount="0">
<quartz:event-generator-job>
<quartz:payload>HTTP Puller</quartz:payload>
</quartz:event-generator-job>
</quartz:inbound-endpoint>
<https:outbound-endpoint exchange-pattern="request-response" host="gist.githubusercontent.com" port="443" method="GET" doc:name="HTTP" encoding="UTF-8" mimeType="application/json" path="Rajeun/b550fe17181610f5c0f0/raw/934bf1e621d6bc056f20dee653dac74275026ba5/file.json"/>
<json:json-to-object-transformer returnClass="java.lang.Object" doc:name="JSON to Object"/>
<choice doc:name="Choice">
<when expression="#[message.payload.sent]">
<logger message="#[message.payloadAs(java.lang.String)]+ HELLO" level="INFO" doc:name="Logger"/>
</when>
<otherwise>
<set-variable variableName="email" value="#[message.payload.email]" doc:name="Variable"/>
<component class="pushv.SendMail" doc:name="Java"/>
<logger message="Error" level="INFO" doc:name="Logger"/>
</otherwise>
</choice>
</flow>
这是我的代码:
package pushv;
import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
public class SendMail {
public static void main(String[] args) {
final String username = "<Frommail>@gmail.com";
final String password = "pass";
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("<Frommail>@gmail.com"));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse("<TomailfromJson>@gmail.com"));
message.setSubject("Testing Subject");
message.setText("Dear Mail Crawler,"
+ "\n\n No spam to my email, please!");
Transport.send(message);
System.out.println("Done");
} catch (MessagingException e) {
throw new RuntimeException(e);
}
}
}
错误:

问题是您正在使用Java类,并且在类中使用
public static void main(String[] args)
,这就是它失败的原因,并且无法找到要调用的方法与使用Java文件并使其复杂化不同,您可以简单地使用smtp out-bound,如下所示,并使用一组有效负载:-
PS:-如果您想使用java类发送电子邮件,请从java类中删除
public static void main(String[] args)
,并使用入口点解析器调用您的方法(如果您的java类包含多个方法) 参考:-http://blogs.mulesoft.org/mule-school-invoking-component-methods-using-entry-point-resolvers/更新答案
将以下内容置于顶部:
然后在流中使用
connector-ref="Gmail"
和smtp出站,如下所示:
