How to map xml attribute values to java class attributes using jaxB or any other better method?

this is my test.xml and i want to tag attribute name values i.e bookid, bookname and noOfPages to attributes of Book.java class

<?xml version="1.0" encoding="UTF-8"?>
<tns:class xmlns:tns="http://ift.tt/1wa7VrH" xmlns:xsi="http://ift.tt/ra1lAU" xsi:schemaLocation="http://ift.tt/1wa7VrH test.xsd ">
<attr name="bookid" primary="true"/>
<attr name="bookname" primary="false"/>
<attr name="noOfPages" primary="false"/>
<attr name="auth_name" primary="false"/>
</tns:class>

---

Book.java

package com.srl.rotelearning.test;

public class Book {

private int bookId;
private String bookname;
private int noOfPages;

public int getBookId() {
    return bookId;
}

public int getNoOfPages() {
    return noOfPages;
}

public void setNoOfPages(int noOfPages) {
    this.noOfPages = noOfPages;
}

public void setBookId(int bookId) {
    this.bookId = bookId;
}

public String getBookname() {
    return bookname;
}

public void setBookname(String bookname) {
    this.bookname = bookname;
}
