java - 速度中的 ResourceNotFoundException

Question

当我使用 File.exists 检查时它是“真的”，但是当我使用 Template t = ve.getTemplate(pathContent); 我收到 ResourceNotFoundException 错误。为什么会这样，

我的 EmailSender 类：

public class EmailSender {
    public static boolean send(String to, String newUsername, String newPassword, String contentPath) {
        try{
            .......................
            VelocityEngine ve = new VelocityEngine();
            ve.init();
            VelocityContext context = new VelocityContext();
            context.put("username", newUsername);
            context.put("password", newPassword);

            Template t = ve.getTemplate(contentPath);
            StringWriter writer = new StringWriter();
            t.merge( context, writer );
            System.out.println(writer.toString());
            return true;

        } catch (Exception e) {
            e.printStackTrace();
            return false;
        }
    }
}

我尝试在我的服务类中传递真实路径

public class UserServiceImpl {
    public ResultDto sendNotifEmail(Users user) {
        try{
            String emailFormatPath = context.getRealPath("emailFormat");
            if(!EmailSender.send(user.getEmail(), user.getUsername(), password, emailFormatPath+"\\emailFormat.vm")){

            }           

        } catch (Exception e) {
            e.printStackTrace();
            return false;
        }
    }
}

谢谢

我通过在我的spring xml（applicationContext.xml）中注入类velocityEngine来解决它

<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>

<bean id="emailSender" class="com.satunol.pms.helper.EmailSender">
    <property name="velocityEngine"><ref bean="velocityEngine"/></property>
</bean>

在我的 EmailSender 类中

private VelocityEngine velocityEngine;
public void setVelocityEngine(VelocityEngine velocityEngine) {
    this.velocityEngine = velocityEngine;
}
......................
Template t = velocityEngine.getTemplate("emailFormat.vm");
StringWriter writer = new StringWriter();
System.out.println(writer.toString());

将我的 emailFormat 放入资源文件夹（WEB-INF/classes）
