hibernate传递给前台json数据的时候有些数据不匹配的解决方法

1.很简单的，不用再添加什么其余的对象，直接就是在原来的对象里添加需要的数据就好了，一定要添加set和get方法。但是后台不需要在进行配置就行了。

2.代码

package com.marvin.book.pojo;import java.util.HashSet;import java.util.Set;/** * Booktype entity. @author MyEclipse Persistence Tools */public class Booktype implements java.io.Serializable {private static final long serialVersionUID = -4161453077878631323L;private int id;private String text;private String description;private boolean leaf;private Booktype booktype;private boolean expandable;private int parent = (this.booktype!=null)?this.booktype.getId():0;private Set books = new HashSet(0);private Set children = new HashSet(0);public int getId() {return id;}public void setId(int id) {this.id = id;}public String getText() {return text;}public void setText(String text) {this.text = text;}public String getDescription() {return description;}public void setDescription(String description) {this.description = description;}public boolean isLeaf() {return leaf;}public void setLeaf(boolean leaf) {this.leaf = leaf;}public Booktype getBooktype() {return booktype;}public void setBooktype(Booktype booktype) {this.booktype = booktype;//精华就在这里哟   关系说明   将一个关联的对象转化为一个列传到前台，千万注意是在这个列所依靠的属性的set方法里面进行赋值啊this.parent = (this.booktype!=null)?this.booktype.getId():0;}public boolean isExpandable() {return expandable;}public void setExpandable(boolean expandable) {this.expandable = expandable;}public int getParent() {return parent;}public void setParent(int parent) {this.parent = (this.booktype!=null)?this.booktype.getId():0;}public Set getBooks() {return books;}public void setBooks(Set books) {this.books = books;}public Set getChildren() {return children;}public void setChildren(Set children) {this.children = children;}public Booktype(int id, String text, String description, boolean leaf,Booktype booktype, boolean expandable, int parent, Set books,Set children) {super();this.id = id;this.text = text;this.description = description;this.leaf = leaf;this.booktype = booktype;this.expandable = expandable;this.parent = parent;this.books = books;this.children = children;this.parent = (this.booktype!=null)?this.booktype.getId():parent;}public Booktype() {super();// TODO Auto-generated constructor stub}}

意思就是说，添加的数据一定要从他的父亲进行添加，要是有父亲，就一定有孩子。
