acegi

Bean Acegi JDBC Spring Security

实现效果图如下：
acegi1.05的新的权限模型针对 hsqldb 数据库，移植到到sqlserver/mysql 需要修改如下文件：
org.acegisecurity.acls.jdbc.BasicLookupStrategy ；
org.acegisecurity.acls.jdbc.JdbcMutableAclService；

JdbcMutableAclService 是最主要的类，对acl和ace的操作都集中在该类；
BasicLookupStrategy 只有一个方法readAclsById 获得实例对象的acl。

要点：
1、搭建基础代码可以参考ss2中的acegi实现（完全拷贝），在roleManager中需要特别注意是，如果采用getHibernateTemplate().saveOrUpdate(o);对对象进行保存或者更新的话，在修改角色对于用户或者角色对应资源的保存角色前，应该将缓存中的role对于的用户和资源的authorities清除rolename，然后更新角色实例，保存角色到cache中。
2、采用ss1中对对象保护的方法，新建com.at21.pm.core.security.acl.domain.AclDomainAware标示接口或者需要实现public long getId()方法。
3、编辑applicationContext-acegi-acl.xml（可以拷贝acegi中contact例子中的文件）。
4、解析acl中几个表对象
ACL_SID：用以保存sid的实例 PrincipalSid 用户实例，GrantedAuthoritySid 角色实例。
ACL_OBJECT_IDENTITY：用户需要保存的实例。字段ENTRIES_INHERITING表示是否继承父级权限。
ACL_ENTRY：用户实例对应sid的权限(read/create/delete/admin) 字段MASK标示权限（具体标示参考org.acegisecurity.acls.domain.BasePermission类）字段GRANTING表示是是否授予某用户/角色该实例的某权限

介绍开发树形实例：
1、保存树形到数据库对应表时，保存该对象到acl模型中调用updateAcl()方法。

java 代码

/**
* @param clazz 需要保护的对象类
* @param id 实例对象id
* @param sid 角色名/用户名
* @param permission 权限
* @param granting 授予/拒绝
* @param entriesInheriting 是否从父类继承权限
* @param parentid 父类实例
*/
public void updateAcl(Class clazz,Serializable id,Sid sid,Permission permission,boolean granting,boolean entriesInheriting,Serializable parentid){
MutableAcl acl;
ObjectIdentity oid = new ObjectIdentityImpl(clazz,id);
try {
acl = (MutableAcl) mutableAclService.readAclById(oid);
} catch (NotFoundException nfe) {
acl = mutableAclService.createAcl(oid);
}
if ( parentid != null){
MutableAcl parentacl;
ObjectIdentity parentoi = new ObjectIdentityImpl(clazz,parentid);
try {
parentacl = (MutableAcl) mutableAclService.readAclById(parentoi);
} catch (NotFoundException nfe) {
parentacl = mutableAclService.createAcl(parentoi);
}
acl.setParent(parentacl);
}
AccessControlEntry sameAce = null;
AccessControlEntry[] aces = acl.getEntries();
if ( aces != null && aces.length >0 ){
for (int i = 0; i < aces.length; i++) {
AccessControlEntry ace = aces[i];
if ( ace.getPermission().getMask() == permission.getMask() && sid.equals(ace.getSid())){
sameAce = ace;
break;
}
}
}
if ( sameAce != null){
acl.deleteAce(sameAce.getId());
}
acl.insertAce(null, permission, sid, granting);
acl.setEntriesInheriting(entriesInheriting);
mutableAclService.updateAcl(acl);
}

如果是从后台直接保存树形（比如采用线程定时更新树形的话），没有web层的请求的话，需要用户后台登陆
保存前添加如下代码

java 代码

Authentication authRequest = new UsernamePasswordAuthenticationToken(admin,admin,new GrantedAuthority[]{new GrantedAuthorityImpl(role_admin)});
SecurityContextHolder.getContext().setAuthentication(authRequest);

2、对某用户授予read的权限。

java 代码

String nodeid = request.getParameter("nodeid");
String rolename = request.getParameter("rolename");
String mark = request.getParameter("mark");
String granted = request.getParameter("granted");
Permission p = mutableAclService.buildFromMask(Integer.parseInt(mark));
updateAcl(Vssdoc.class, Long.parseLong(nodeid), new GrantedAuthoritySid(rolename), p, Boolean.parseBoolean(granted), true, null);

3、完成了。
