首注:本学习教程为传智播客汤阳光讲师所公布的免费OA项目视频我的文字版实践笔记,本人用此来加强巩固自己开发知识,如有网友转载,请注明。谢谢。

一 实体设计:

  1.权限实体设计:

   1)属性设计:

    主键:id

    关联属性:Set<Role> roles,Set<Privilege> privileges,Privilege parent,Set<Privilege> children

    一般属性:name,url

    特殊属性:暂无

   2)涉及到3个实体:User(用户),Role(岗位角色),Privilege(权限)。其关系映射如下图:

    bubuko.com,布布扣

二 javabean,映射文件,表的创建:

  1.javabean:Privilege.java 

  bubuko.com,布布扣
 1 package cn.clear.oa.domain;
 2 
 3 import java.util.HashSet;
 4 import java.util.Set;
 5 /**
 6  * 权限实体类
 7  * @ClassName: Privilege
 8  * @Description: TODO
 9  * @author: clear
10  * @date: 2014-10-29 下午4:45:21
11  */
12 public class Privilege {
13 
14     private Long id;
15     private String name;
16     private String url;
17     private Privilege parent;
18     private Set<Role> roles = new HashSet<Role>();
19     private Set<Privilege> children = new HashSet<Privilege>();
20     public Long getId() {
21         return id;
22     }
23     public void setId(Long id) {
24         this.id = id;
25     }
26     public String getName() {
27         return name;
28     }
29     public void setName(String name) {
30         this.name = name;
31     }
32     public String getUrl() {
33         return url;
34     }
35     public void setUrl(String url) {
36         this.url = url;
37     }
38     public Set<Role> getRoles() {
39         return roles;
40     }
41     public void setRoles(Set<Role> roles) {
42         this.roles = roles;
43     }
44     public Privilege getParent() {
45         return parent;
46     }
47     public void setParent(Privilege parent) {
48         this.parent = parent;
49     }
50     public Set<Privilege> getChildren() {
51         return children;
52     }
53     public void setChildren(Set<Privilege> children) {
54         this.children = children;
55     }
56     
57 }
Privilege.java

  2.Privilege.hbm.xml:

  bubuko.com,布布扣
 1 <?xml version="1.0"?>
 2 <!DOCTYPE hibernate-mapping PUBLIC 
 3     "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
 4     "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
 5 
 6 <hibernate-mapping package="cn.clear.oa.domain">
 7     <class name="Privilege" table="oa_privilege">
 8         <id name="id">
 9             <generator class="native" />
10         </id>
11         <property name="name" />
12         <property name="url" />
13         <!-- roles属性,本类与Role的多对多 -->
14         <set name="roles" table="oa_privilege_role">
15             <key column="privilegeId"></key>
16             <many-to-many class="Role" column="roleId"></many-to-many>
17         </set> 
18         <!-- parent属性,本类与Privilege(上级)的多对一 -->
19         <many-to-one name="parent" class="Privilege" column="parentId"></many-to-one>
20         <!-- children属性,本类与Privilege(下级级)的一对多 -->
21         <set name="children" cascade="delete" order-by="id ASC">
22             <key column="parentId"></key>
23             <one-to-many class="Privilege"/>
24         </set>
25     </class>
26 </hibernate-mapping>
Privilege.hbm.xml

  3.在Role.java中加入和权限的关联属性:

  private Set<Privilege> privileges = new HashSet<Privilege>();

  //get与set方法

  public Set<Privilege> getPrivileges() {

    return privileges;

  }

  public void setPrivileges(Set<Privilege> privileges) {

    this.privileges = privileges;

  }

  4.在Role.hbm.xml中加入和权限的关联关系属性:

  <!-- privileges属性,本类与Privilege的多对多 -->

  <set name="privileges" table="oa_privilege_role">

    <key column="roleId"></key>

    <many-to-many class="Privilege" column="privilegeId"></many-to-many>

  </set>

  5.将Privilege.hbm.xml加入hibernate.cfg.xml中:

  <mapping resource="cn/clear/oa/domain/Privilege.hbm.xml" />

  6.测试建表。
