速度找不到模板 [英] Velocity Not Finding Template

问题描述

我正在尝试启动并运行Apache Velocity.我的my.test.package包中有一个TestClass.class类.

I am trying to get Apache Velocity up and running. I have a TestClass.class class in my my.test.package package.

public class TestClass {
    public static Template getTestTemplate() throws Exception {
        Velocity.init();
        return Velocity.getTemplate("MyTestTemplate.vm");
    } 
}

在同一位置(my.test.package)，我有MyTestTemplate.vm文件.

In the same location (my.test.package) I have the MyTestTemplate.vm file.

上面的代码导致抛出异常，表示为Unable to find resource 'MyTestTemplate.vm'.我不确定是什么问题. Velocity不会在同一软件包中查找文件吗? (注意:我最初在资源文件夹中有该文件，但是出于测试目的，将其放在同一文件夹下).

The above code causes an exception to be thrown, saying Unable to find resource 'MyTestTemplate.vm'. I am not sure what the issue is. Does Velocity not look for the file in the same package? (Note: I originally had the file in the resources folder, but put it under the same folder for testing purposes).

推荐答案

好，知道了.

所以我想也许Velocity正在查看我的WEB-INF/classes文件夹.我到那里看时才发现MyTestTemplate.vm文件不存在.原来，我需要更新在资源上复制的Ant脚本，以包含.vm文件.

So I figured maybe Velocity was looking in my WEB-INF/classes folder. I looked in there only to discover that the MyTestTemplate.vm file wasn't there. Turned out I needed to update my Ant script that copied over the resources to include .vm files.

<include name="**/*.vm"/>

然后我需要更新配置，以便Velocity知道要在classes文件夹中查找.

Then I needed to update my configuration so that Velocity knew to look in the classes folder.

VelocityEngine velocityEngine = new VelocityEngine();
velocityEngine.setProperty("resource.loader", "class");
velocityEngine.setProperty("class.resource.loader.class", "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");
velocityEngine.init();

然后，当您获得模板时，只需在WEB-INF/classes部分之后提供路径.

Then when you get the template, you just need to provide the path after the WEB-INF/classes part.

velocityEngine.getTemplate("path/to/resource/MyTestTemplate.vm");

我确定有某种方法可以使模板脱离文件路径，但我不再关心;)

I am sure there is some way to get the templates off of the file path, but I stopped caring ;)
