[英]How can I get a precise callgraph for a web Application using spring FrameWork by soot SPARK?
[英]How can I make a for loop in Spark Web Framework and the Velocity Template Framework?
這是我的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());
}
}
這是view_students_layout.vtl
<!DOCTYPE html>

<div class="container">
<h1>Students</h1>
<ul>
#foreach( $Student in $students )
<li>${Student.name}</li>
#end
</ul>
</div>
</body>
</html>
當我運行spark時,我得到以下信息
<!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>
我想念或誤解了什么? 我是否以錯誤的方式將數組發送到框架?
謝謝。
Student類必須具有public String getName()
方法或public String get(String key)
方法。 您正在嘗試直接訪問name
字段,或者忘記了公開其訪問器。
如果要直接向模板公開公共字段,則需要2.0.0-SNAPSHOT版本(開發版本)。 請參閱http://velocity.apache.org/engine/devel/developer-guide.html部分可插拔自省 。
