Question

春天新手。我抓住了以下异常：

2012-06-14 16:20:57,719 [http-8080-6] ERROR com.nimchip.lmu.data.service.impl.CoworkerServiceImpl - Error sending mail:
org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.NoSuchProviderException: Unable to locate provider for protocol: smtp. Failed messages: javax.mail.NoSuchProviderException: Unable to locate provider for protocol: smtp

我有一个mail-config.xml，它在我的web.xml中注册。这是：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

    <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
        <property name="host" value="10.30.137.190"/>
        <property name="port" value="25"/>
    </bean>

</beans>

我应该能够匿名登录到指定的邮件服务器，因此不需要用户或密码。

我错过了什么？

Answer 1

您的类路径中是否有mail.jar和activation.jar？

这些类应该提供smtp-provider。

如果您使用的是maven，只需将其添加到您的pom：

    <dependency>
        <groupId>javax.mail</groupId>
        <artifactId>mail</artifactId>
        <version>1.4</version>
    </dependency>

    <dependency>
        <groupId>javax.activation</groupId>
        <artifactId>activation</artifactId>
        <version>1.0.2</version>
    </dependency>

Answer 2

我遇到了同样的问题。我使用mailapi作为工件ID，这导致了问题。我换了 <artifactId>mailapi</artifactId> <artifactId>mail</artifactId>并且工作正常

无法找到协议提供程序：smtp
