找不到速度框架资源异常

Question

I'm trying to run velocity email sender program in Java 1.6 but its not finding recourse...

    VelocityContext context = new VelocityContext();
    context.put("name", "mike");

    // Initialize the engine
    try {
    VelocityEngine ve = new VelocityEngine();
    templateName = "myfile_en.vm";

    // Load the template
    Template template = ve.getTemplate(templateName, "UTF-8");

    // Render the template into a writer
    StringWriter writer = new StringWriter();
    template.merge(context, writer);

Cam any one help me out why I'm not able to load myfile_en.vm??? I tried giving full absolute path as well but still same error: ResourceNotFound

I'm running it directly from eclipse. Any help is much appreciated.

Thanks!

Answer 1

It really depends on where your template file is. Velocity always has an issue with it. To get around it you need to ensure that the templates are locatable on your classpath. Either in a jar or on the filesystem directly. Once its on your classpath, init Velocity like this...

private static void initVelocity() throws Exception {
    java.util.Properties p = new java.util.Properties();
    p.setProperty("resource.loader", "class");
    p.setProperty("class.resource.loader.class", "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");
    Velocity.init(p);
}

This tells Velocity to look for template files in the classpath.

Only change the path into bean

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