| --角色继承关系表create table SNOICS_RI ( RI_PARE_ROLEID VARCHAR2(32) not null, RI_CHILD_ROLEID VARCHAR2(32) not null, constraint PK_SNOICS_RI primary key (RI_PARE_ROLEID, RI_CHILD_ROLEID));--角色表create table SNOICS_ROLE ( ROLE_ID VARCHAR2(32) not null, ROLE_NAME VARCHAR2(32) not null, ROLE_FORBID VARCHAR2(1), ROLE_DESCRIPT VARCHAR2(500), constraint PK_SNOICS_ROLE primary key (ROLE_ID));角色资料存放在SNOICS_ROLE中角色之间可以继承，而且可以多重继承,角色的继承关系存放在SNOICS_RI可以使用SNOICS_ROLE自己到自己的多对多的关系来进行配置-----------------------------------------------------------------------------------------------------POJO:package com.snoics.cmp.security.dao.spring.hibernate.pojo;
import java.io.Serializable;import java.util.Set;public class RolePOJO implements Serializable { private static final long serialVersionUID = -4776193447586778294L; private String roleid; private String rolename; private String roleforbid; private String roledescript; private Set user; private Set rolePermission; private Set roleP; private Set roleC;
/** * @return Returns the roleC. */ public Set getRoleC() { return roleC; }
/** * @param roleC The roleC to set. */ public void setRoleC(Set roleC) { this.roleC = roleC; }
/** * @return Returns the roleP. */ public Set getRoleP() { return roleP; }
/** * @param roleP The roleP to set. */ public void setRoleP(Set roleP) { this.roleP = roleP; }
/** * @return Returns the rolePermission. */ public Set getRolePermission() { return rolePermission; }
/** * @param rolePermission The rolePermission to set. */ public void setRolePermission(Set rolePermission) { this.rolePermission = rolePermission; }

/** * @return Returns the roledescript. */ public String getRoledescript() { return roledescript; }
/** * @param roledescript The roledescript to set. */ public void setRoledescript(String roledescript) { this.roledescript = roledescript; }
/** * @return Returns the roleforbid. */ public String getRoleforbid() { return roleforbid; }

/** * @return Returns the rolename. */ public String getRolename() { return rolename; }
/** * @param rolename The rolename to set. */ public void setRolename(String rolename) { this.rolename = rolename; }}-----------------------------------------------------------------------------------------------------role.hbm.xml中的继承关系部分的配置 <set name="roleP" table="SNOICS_RI" cascade="all" inverse="false" lazy="true"> <key column="RI_CHILD_ROLEID"/> <many-to-many column="RI_PARE_ROLEID" class="com.snoics.cmp.security.dao.spring.hibernate.pojo.RolePOJO"/> </set> <set name="roleC" table="SNOICS_RI" cascade="all" inverse="false" lazy="true"> <key column="RI_PARE_ROLEID"/> <many-to-many column="RI_CHILD_ROLEID" class="com.snoics.cmp.security.dao.spring.hibernate.pojo.RolePOJO"/> </set> |
