wicket pallete初识
wicket 之Pallete
使用Pallete实现下面效果：
Html代码 MyPallete.html：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<form wicket:id="form">
<span wicket:id="palette">面板区域</span>
</form>
</body>
</html>
java 代码：
Book.java
mport java.io.Serializable;
//实现比较器Comparable
public class Book implements Serializable,Comparable<Book> {
/**
* serialVersionUID
*/
private static final long serialVersionUID = 1L;
private String id;
private String name;
public Book(String id, String name) {
super();
this.id = id;
this.name = name;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public int compareTo(Book o) {
return id.compareToIgnoreCase(o.getId());
}
}
