这是我的 Main.java

public class Main {
    public static void main(String[] args) {

        // Create some students
        Student students[] = new Student[4];

        students[0] = new Student("Abe");
        students[1] = new Student("Bill");
        students[2] = new Student("Chris");
        students[3] = new Student("Darrel");

        staticFileLocation("/public");

        String layout = "templates/layout.vtl";

        get("/", (request, response) -> {
            HashMap model = new HashMap();
            model.put("template", "templates/home.vtl" );
            return new ModelAndView(model, layout);
        }, new VelocityTemplateEngine());

        get("/view_students", (request, response) -> {
            HashMap model = new HashMap();

            model.put("students", students );
            // model.put("student", new Student() );

            return new ModelAndView(model, "templates/view_students_layout.vtl");
        }, new VelocityTemplateEngine());

    }
}

这是 view_students_layout.vtl

        <li>${Student.name}</li>
      #end

    </ul>

    </div>
  </body>
</html>

当我运行 spark 我得到以下

<!DOCTYPE html>
<html>
  <head>
    <title>Hello Friend!</title>
    <link rel='stylesheet' href='https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css'>
  </head>
  <body>
    <div class="container">

    <h1>Students</h1>

    <ul>

              <li>${Student.name}</li>
              <li>${Student.name}</li>
              <li>${Student.name}</li>
              <li>${Student.name}</li>

    </ul>

    </div>
  </body>
</html>

我错过了什么或误解了什么？我是否以错误的方式将数组发送到框架？

谢谢你。

Student 类必须有一个public String getName()方法，或者一个public String get(String key)方法。您要么尝试直接访问该name字段，要么忘记将其访问器公开。

如果您想直接向模板公开公共字段，那么您需要 2.0.0-SNAPSHOT 版本（开发版本）。请参阅http://velocity.apache.org/engine/devel/developer-guide.html部分Pluggable Introspection。
