Java 速度零点异常

我想使用velocity模板发送邮件

<bean id="sendMail" class="com.myclass.app.SendMail">
    <property name="mailSender" ref="mailSender"/>
    <property name="velocityEngine" ref="velocityEngine"/>
</bean>

<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
    <property name="velocityProperties">
        <value>
            resource.loader=class
            class.resource.loader.class=org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
        </value>
    </property>
</bean>

我的配置基于Spring3.1文档

<bean id="sendMail" class="com.myclass.app.SendMail">
    <property name="mailSender" ref="mailSender"/>
    <property name="velocityEngine" ref="velocityEngine"/>
</bean>

<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
    <property name="velocityProperties">
        <value>
            resource.loader=class
            class.resource.loader.class=org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
        </value>
    </property>
</bean>

我有一个配置为的xml文件：

<?xml version="1.0" encoding="UTF-8"?>

<bean id="sendMail" class="com.myclass.app.SendMail">
    <property name="mailSender" ref="mailSender"/>
    <property name="velocityEngine" ref="velocityEngine"/>
</bean>

<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
    <property name="velocityProperties">
        <value>
            resource.loader=class
            class.resource.loader.class=org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
        </value>
    </property>
</bean>

我的vm文件位于resources文件夹中

<bean id="sendMail" class="com.myclass.app.SendMail">
    <property name="mailSender" ref="mailSender"/>
    <property name="velocityEngine" ref="velocityEngine"/>
</bean>

<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
    <property name="velocityProperties">
        <value>
            resource.loader=class
            class.resource.loader.class=org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
        </value>
    </property>
</bean>

和所有我收到的id空点异常

<bean id="sendMail" class="com.myclass.app.SendMail">
    <property name="mailSender" ref="mailSender"/>
    <property name="velocityEngine" ref="velocityEngine"/>
</bean>

<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
    <property name="velocityProperties">
        <value>
            resource.loader=class
            class.resource.loader.class=org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
        </value>
    </property>
</bean>

回答没有给我更多

<bean id="sendMail" class="com.myclass.app.SendMail">
    <property name="mailSender" ref="mailSender"/>
    <property name="velocityEngine" ref="velocityEngine"/>
</bean>

<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
    <property name="velocityProperties">
        <value>
            resource.loader=class
            class.resource.loader.class=org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
        </value>
    </property>
</bean>

你有什么想法，怎么办？

你的模板不能在资源中，它们需要在你可以在velocityEngine中配置的类路径中

<bean id="sendMail" class="com.myclass.app.SendMail">
    <property name="mailSender" ref="mailSender"/>
    <property name="velocityEngine" ref="velocityEngine"/>
</bean>

<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
    <property name="velocityProperties">
        <value>
            resource.loader=class
            class.resource.loader.class=org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
        </value>
    </property>
</bean>

在applicationContext.xml中：

<bean id="sendMail" class="com.myclass.app.SendMail">
    <property name="mailSender" ref="mailSender"/>
    <property name="velocityEngine" ref="velocityEngine"/>
</bean>

<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
    <property name="velocityProperties">
        <value>
            resource.loader=class
            class.resource.loader.class=org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
        </value>
    </property>
</bean>

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
  <property name="host" value="ADDRESS_OF_YOUR_SMTP_SERVER"/>
  <property name="defaultEncoding" value="UTF-8"/>
  <property name="port" value="XX_PORT_SERVER"/>
  <property name="javaMailProperties">  
      <props>
        <prop key="mail.smtps.auth">false</prop> <!-- depending on your smtp server -->
        <prop key="mail.smtp.starttls.enable">false</prop>
      </props>
  </property>
</bean>

<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean" p:resourceLoaderPath="classpath:META-INF/velocity" />

最后，要发送电子邮件，请使用MIMessagePreparator：

<bean id="sendMail" class="com.myclass.app.SendMail">
    <property name="mailSender" ref="mailSender"/>
    <property name="velocityEngine" ref="velocityEngine"/>
</bean>

<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
    <property name="velocityProperties">
        <value>
            resource.loader=class
            class.resource.loader.class=org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
        </value>
    </property>
</bean>

            MimeMessagePreparator preparator = new MimeMessagePreparator() {
            @Override
            public void prepare(MimeMessage mimeMessage) throws Exception {
               MimeMessageHelper message = new MimeMessageHelper(mimeMessage);
               message.setTo("blabla@test.com");
               message.setSubject("Email test");

               String text = VelocityEngineUtils.mergeTemplateIntoString(
                   velocityEngine, template, keywords);
               message.setText(text, true);

             }
          };

          //Send email using the autowired mailSender
          this.mailSender.send(preparator);

好的，问题是@Autowired miss
