我按照示例中所示的说明来渲染速度模板：

public static void main(final String[] args) {

    get(new VelocityRoute("/hello") {
        @Override
        public Object handle(final Request request, final Response response) {
            Map<String, Object> model = new HashMap<>();
            model.put("hello", "Velocity World");
            model.put("person", new Person("Foobar"));
            // The wm files are located under the resources directory
            return modelAndView(model, "hello.wm");
        }
    });

}

但速度似乎没有找到我的模板：

我不确定问题是什么。我试图玩弄速度，但它似乎永远找不到我的模板。

有关信息，这是我的项目的样子：

project-root
 | src/main/java
 |  | com.stackoverflow.my-spark-app
 |  |   | SparkMain.java
 |  |   | Person.java
 | src/main/resources
 |  |   | hello.wm
 | pom.xml

实际上，它对我有用。我使用速度模板引擎创建了一个简单的 spark 应用程序。

public class Server {

    public static void main(String[] args) {
        Spark.get(new VelocityRoute("/hello") {
            @Override
            public Object handle(final Request request, final Response response) {
                Map<String, Object> model = new HashMap<String, Object>();
                model.put("hello", "Velocity World");
                model.put("person", new Person("Foobar"));

                // The wm files are located under the resources directory
                return modelAndView(model, "hello.wm");
            }
        });
    }

    public static class Person {
        private String name;

        public Person(String name) {
            this.name = name;
        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }
    }
}

我的目录结构类似

src
    main
        java
            com.stackoverflow
                Server.java
        resources
            hello.wm

它确实选择了模板。

您使用的是哪个版本的 spark-core 和 spark-template-velocity？你能检查一下模板文件是否被复制到 target\classes 文件夹吗？
