oa组织机构(树状结构)

package com.bjsxt.oa.model;

import java.util.Set;

public class Organization {
	private int id;
	private String name;
	private String sn;
	private String description;
	private Organization parent;
	private Set children;
	
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getSn() {
		return sn;
	}
	public void setSn(String sn) {
		this.sn = sn;
	}
	public String getDescription() {
		return description;
	}
	public void setDescription(String description) {
		this.description = description;
	}
	public Organization getParent() {
		return parent;
	}
	public void setParent(Organization parent) {
		this.parent = parent;
	}
	public Set getChildren() {
		return children;
	}
	public void setChildren(Set children) {
		this.children = children;
	}
}

many-to-one one-to-many 双向关联
这里的pid要一样
inverse=true 主控表为多的一方

人员和组织机构的关系是many-to-one单向外键关联
这里的分页是用pagertaglib
在Criteria接口中有两个方法:setFirstResult方法和setMaxResults方法。
其中setFirstResult设置了记录的开始位置(0表示第1条记录),
setMaxResults设置了返回的记录数。

jar包是ssh整合的jar包
