先列出来正确的解析代码，接着再描述问题详情。

首先是用到的JavaBean

package com.jadyer.model;

public class User {
	private String name;
	private Book book;
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public Book getBook() {
		return book;
	}
	public void setBook(Book book) {
		this.book = book;
	}
}

package com.jadyer.model;

public class Book {
	private String name;
//	private List<Author> author = new ArrayList<Author>();
	private Author author;
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
//	public List<Author> getAuthor() {
//		return author;
//	}
//	public void setAuthor(List<Author> author) {
//		this.author = author;
//	}
	public Author getAuthor() {
		return author;
	}
	public void setAuthor(Author author) {
		this.author = author;
	}
}

package com.jadyer.model;

public class Author {
	private String name;
	private int money;
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getMoney() {
		return money;
	}
	public void setMoney(int money) {
		this.money = money;
	}
}
