這裏是我的Main.java如何在Spark Web Framework和Velocity Template Framework中創建for循環?
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());
}
}
這裏是view_students_layout.vtl

當我運行的火花,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>
我在想什麼或誤解?我是否以錯誤的方式將數組發送到框架?
謝謝。
非常感謝!我試着看着你鏈接的相同的指南,無法找到任何關於我的問題。 – Ergosphere
