Spring Bean自动装配错误

Question

我正在尝试在我的应用程序中实现电子邮件功能,但我一直在努力

No matching bean of type [org.springframework.mail.javamail.JavaMailSenderImpl] found for dependency:  expected at least 1 bean which qualifies as autowire candidate for this dependency.

谁能指出我做错了什么？

bean的xml配置是:

<beans:beans xmlns="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"   
xsi:schemaLocation="
    http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

<!-- Enables the Spring MVC @Controller programming model -->
<annotation-driven />
<context:annotation-config/>
//...other stuff

<beans:bean id="mailSession" class="org.springframework.jndi.JndiObjectFactoryBean">
    <beans:property name="jndiName" value="EmailServer" />
</beans:bean>

<beans:bean id="emailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    <beans:property name="session" ref="mailSession"/>
</beans:bean>

EmailServiceImpl类:

@Service
public class EmailServiceImpl implements EmailService {

    @Autowired
    private JavaMailSenderImpl emailSender; 

    //more code..
}

感谢大家的回复。我无法让自动装配工作，但我通过执行以下操作使整体电子邮件解决方案工作：

1. 在 weblogic 中设置mailSession，jndi 名称为“myMailSession”

添加到 servlet-context.xml：

<beans:bean id="mailSession" class="org.springframework.jndi.JndiObjectFactoryBean">
    <beans:property name="jndiName" value="myMailSession" />
</beans:bean>

<beans:bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    <beans:property name="session" ref="mailSession"/>
</beans:bean>

<beans:bean id="emailServiceImpl" class="com.name.here.business.EmailServiceImpl">
  <beans:property name="mailSender" ref="mailSender"/>
</beans:bean>

添加到 web.xml：

<resource-ref>
   <description>the email session</description>
   <res-ref-name>myMailSession</res-ref-name>
   <res-type>javax.mail.Session</res-type>
   <res-auth>Container</res-auth>
</resource-ref> 

添加到 weblogic.xml：

<resource-description>
  <res-ref-name>myMailSession</res-ref-name>
  <jndi-name>myMailSession</jndi-name>
</resource-description>

电子邮件服务实现：

@Service
public class EmailServiceImpl implements EmailService {

    private JavaMailSender mailSender;

    public void setMailSender(JavaMailSender mailSender) {
        this.mailSender = mailSender;
    }
    //..other code
}
