下面的代码显示了如何使用ui:repeat创建一个表。
下面的代码来自UserBean.java。
package cn..common;
import java.io.Serializable;
import java.math.BigDecimal;
import java.util.ArrayList;
import java.util.Arrays;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
@ManagedBean(name="book")
@SessionScoped
public class UserBean implements Serializable{
private static final long serialVersionUID = 1L;
private static final ArrayList<Book> bookList =
new ArrayList<Book>(Arrays.asList(
new Book("1", "CSS", new BigDecimal("711.00"), 1),
new Book("2", "SQL", new BigDecimal("522.00"), 2),
new Book("3", "Java", new BigDecimal("13333.00"), 8),
new Book("4", "HTML", new BigDecimal("5244.00"), 3),
new Book("5", "Web", new BigDecimal("441.00"), 10)
));
public ArrayList<Book> getBookList() {
return bookList;
}
public String deleteAction(Book book) {
bookList.remove(book);
return null;
}
public static class Book{
String bookNo;
String productName;
BigDecimal price;
int qty;
public Book(String bookNo, String productName,
BigDecimal price, int qty) {
this.bookNo = bookNo;
this.productName = productName;
this.price = price;
this.qty = qty;
}
public String getBookNo() {
return bookNo;
}
public void setBookNo(String bookNo) {
this.bookNo = bookNo;
}
public String getProductName() {
return productName;
}
public void setProductName(String productName) {
this.productName = productName;
}
public BigDecimal getPrice() {
return price;
}
public void setPrice(BigDecimal price) {
this.price = price;
}
public int getQty() {
return qty;
}
public void setQty(int qty) {
this.qty = qty;
}
}
}
