Spring Security3的搭建使用

最近接觸項目，發現項目用到了很多新鮮東西，也不能說是新鮮，只能說自己沒有接觸過，於是閒的無聊一項一項學習學習，別人問到也說上個七七八八。

今天可算是把spring-security搭建了出來並且運行了起來，主要是自己太菜，其實最後看來也就那麼回事。

1.數據庫的設計和搭建
用戶、角色、權限、資源以及關聯表用戶--角色、角色--權限、權限--資源總共七張表。

用戶表

create table SYS_USERS
(
  USER_ID       VARCHAR2(32) not null,
  USER_ACCOUNT  VARCHAR2(30),
  USER_NAME     VARCHAR2(40),
  USER_PASSWORD VARCHAR2(100),
  USER_DESC     VARCHAR2(100),
  ENABLED       NUMBER(1),
  ISSYS         NUMBER(1),
  USER_DEPT     VARCHAR2(20),
  USER_DUTY     VARCHAR2(10),
  SUB_SYSTEM    VARCHAR2(30)
 );
alter table SYS_USERS add constraint PK_PUB_USERS primary key (USER_ID);

角色表

create table SYS_ROLES
(
  ROLE_ID   VARCHAR2(32) not null,
  ROLE_NAME VARCHAR2(40),
  ROLE_DESC VARCHAR2(100),
  ENABLED   NUMBER(1),
  ISSYS     NUMBER(1),
  MODULE    VARCHAR2(4)
);
alter table SYS_ROLES add constraint PK_PUB_ROLES primary key (ROLE_ID);

權限表

create table SYS_AUTHORITIES
(
  AUTHORITY_ID   VARCHAR2(32) not null,
  AUTHORITY_NAME VARCHAR2(40),
  AUTHORITY_DESC VARCHAR2(100),
  ENABLED        NUMBER(1),
  ISSYS          NUMBER(1),
  MODULE         VARCHAR2(4)
);
alter table SYS_AUTHORITIES add constraint PK_PUB_AUTHORITIES primary key (AUTHORITY_ID);

資源表

create table SYS_RESOURCES
(
  RESOURCE_ID     VARCHAR2(32) not null,
  RESOURCE_NAME   VARCHAR2(100),
  RESOURCE_DESC   VARCHAR2(100),
  RESOURCE_TYPE   VARCHAR2(40),
  RESOURCE_STRING VARCHAR2(200),
  PRIORITY        NUMBER(1),
  ENABLED         NUMBER(1),
  ISSYS           NUMBER(1),
  MODULE          VARCHAR2(4)
);
alter table SYS_RESOURCES add constraint PK_PUB_RESOURCES primary key (RESOURCE_ID);

用戶角色表

create table SYS_USERS_ROLES
(
  ID      NUMBER(13) not null,
  USER_ID VARCHAR2(32),
  ROLE_ID VARCHAR2(32),
  ENABLED NUMBER(1)
);
-- Create/Recreate primary, unique and foreign key constraints 
alter table SYS_USERS_ROLES  add constraint PK_PUB_USERS_ROLES primary key (ID);

alter table SYS_USERS_ROLES  add constraint FK_USERS_ROLES_ROLES foreign key (ROLE_ID)  references SYS_ROLES (ROLE_ID);
alter table SYS_USERS_ROLES  add constraint FK_USERS_ROLES_USERS foreign key (USER_ID)  references SYS_USERS (USER_ID);

角色權限表

create table SYS_ROLES_AUTHORITIES
(
  ID           NUMBER(13) not null,
  ROLE_ID      VARCHAR2(32),
  AUTHORITY_ID VARCHAR2(32),
  ENABLED      NUMBER(1)
);
-- Create/Recreate primary, unique and foreign key constraints 
alter table SYS_ROLES_AUTHORITIES  add constraint PK_PUB_ROLES_AUTHORITY primary key (ID);
alter table SYS_ROLES_AUTHORITIES  add constraint FK_PUB_ROLES_AUTHORITIES_AU foreign key (AUTHORITY_ID)  references SYS_AUTHORITIES (AUTHORITY_ID);
alter table SYS_ROLES_AUTHORITIES  add constraint FK_PUB_ROLES_AUTHORITIES_ROLES foreign key (ROLE_ID)  references SYS_ROLES (ROLE_ID);

權限資源表

create table SYS_AUTHORITIES_RESOURCES
(
  ID           NUMBER(13) not null,
  AUTHORITY_ID VARCHAR2(32),
  RESOURCE_ID  VARCHAR2(32),
  ENABLED      NUMBER(1)
);
-- Create/Recreate primary, unique and foreign key constraints 
alter table SYS_AUTHORITIES_RESOURCES  add constraint PK_PUB_AUTHORITIES_RE primary key (ID);
  
alter table SYS_AUTHORITIES_RESOURCES  add constraint FK_PUB_AUTHORITIES_RE_AU foreign key (AUTHORITY_ID)  references SYS_AUTHORITIES (AUTHORITY_ID);
alter table SYS_AUTHORITIES_RESOURCES  add constraint FK_PUB_AUTHORITIES_RE_RE foreign key (RESOURCE_ID)  references SYS_RESOURCES (RESOURCE_ID);

加入關聯的數據就可以了

2.3DAO層和service層的創建

最近看到通用dao,模仿着寫了一個在這裏

BaseDao.java

package org.joshua.ss.dao;

import java.io.Serializable;
import java.util.List;

/**
 * 
 * @author Joshua
 *
 * @param <T>
 * 				DAO操作的對象類型
 * @param <PK>
 * 				主鍵類型
 */
public interface BaseDao<T,PK extends Serializable> {
	
	
	/**
	 * 按id獲取對象.
	 * 
	 */
	T getById(PK id);
	
	/**
	 * 保存新增或修改的對象.
	 * 
	 */
	T save(T object);
	
	/** 
	 * 按id刪除對象.
	 */
	void remove(PK id);
	
	/**
	 * 刪除對象.
	 */
	void remove(final T object);
	
	/**
	 * 查詢全部對象
	 */
	List<T> getAll();
	
	
}

SysAuthoritiesDao.java接口下同

package org.joshua.ss.dao;
/**
*@author Joshua
*@version 2011-12-15 上午11:06:22
*/
public interface SysAuthoritiesDao{

}

SysAuthoritiesResourcesDao.java
SysResourcesDao.java
SysRolesAuthoritiesDao.java
SysRolesDao.java
SysUsersDao.java
SysUsersRolesDao.java

dao層接口的實現類

BaseDaoImpl.java

package org.joshua.ss.dao.daoimpl;

import java.io.Serializable;
import java.lang.reflect.ParameterizedType;
import java.lang.reflect.Type;
import java.util.List;

import javax.annotation.Resource;

import org.joshua.ss.dao.BaseDao;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.util.Assert;

/**
 *@author Joshua

 */
/**
 * 可以在service層直接調用,也可以在DAO層擴展調用
 */
public class BaseDaoImpl<T, PK extends Serializable> implements BaseDao<T, PK>{
	
	@Resource(name="hibernateTemplate")
	private HibernateTemplate hibernateTemplate;
	
	private Class<T> persistentClass;
	/**
     * 用於Dao層子類使用的構造函數. 通過子類的泛型定義取得對象類型
     */

	@SuppressWarnings("unchecked")
	public BaseDaoImpl(){
		//getClass() 返回表示此 Class 所表示的實體（類、接口、基本類型或 void）的超類的 Class。
		this.persistentClass=(Class<T>)getSuperClassGenricType(getClass(), 0);
	}
	public List<T> getAll() {		
		return hibernateTemplate.loadAll(this.persistentClass);
	}

	public T getById(PK id) {
		Assert.notNull(id, "id 不可空");
		T entity =hibernateTemplate.get(this.persistentClass, id);
		return entity;
	}

	public void remove(PK id) {
		Assert.notNull(id, "id 不可空!");
		hibernateTemplate.delete(this.getById(id));		
	}

	public void remove(final T entity) {
		Assert.notNull(entity, "entity 不可空!");
		hibernateTemplate.delete(entity);
	}

	public T save(T entity) {
		Assert.notNull(entity, "entity 不可空!");		
		return hibernateTemplate.merge(entity);
	}
	/**
     * 通過反射, 獲得定義Class時聲明的父類的泛型參數的類型. 如無法找到, 返回Object.class.
     * 
     *@param clazz

     */
    @SuppressWarnings("unchecked")
    public static Class<Object> getSuperClassGenricType(final Class clazz, final int index) {
    	
    	//返回表示此 Class 所表示的實體（類、接口、基本類型或 void）的直接超類的 Type。
        Type genType = clazz.getGenericSuperclass();

        if (!(genType instanceof ParameterizedType)) {
           return Object.class;
        }
        //返回表示此類型實際類型參數的 Type 對象的數組。
        Type[] params = ((ParameterizedType) genType).getActualTypeArguments();

        if (index >= params.length || index < 0) {
                     return Object.class;
        }
        if (!(params[index] instanceof Class)) {
              return Object.class;
        }

        return (Class) params[index];
    }

}

SysAuthoritiesDaoImpl.java

package org.joshua.ss.dao.daoimpl;

import org.joshua.ss.dao.SysAuthoritiesDao;
import org.joshua.ss.entity.SysAuthorities;

/**
 *@author Joshua
 *@version 2011-12-15 上午11:06:22
 */
public class SysAuthoritiesDaoImpl extends BaseDaoImpl<SysAuthorities, Long> implements SysAuthoritiesDao {

}

下同，繼承通用dao傳遞實體類型，也可自定義方法
SysAuthoritiesResourcesDaoImpl.java
SysResourcesDaoImpl.java
SysRolesAuthoritiesDaoImpl.java
SysRolesDaoImpl.java
SysUsersDaoImpl.java

package org.joshua.ss.dao.daoimpl;



import java.util.List;

import javax.annotation.Resource;

import org.joshua.ss.dao.SysUsersDao;


import org.joshua.ss.entity.SysUsers;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Service;

/**
 *@author Joshua
 *@version 2011-12-15 上午11:08:02
 */
@Service("sysUsersDaoImpl")
public class SysUsersDaoImpl extends BaseDaoImpl<SysUsersDao, Long> implements
		SysUsersDao {
	@Resource(name="hibernateTemplate")
	private HibernateTemplate hibernateTemplate;


	public SysUsers findByUserAccount(String userName) {
		try {
			SysUsers instance;
			List<SysUsers> instances = hibernateTemplate.find(
					"from SysUsers where userAccount='" + userName+"'");
			if ( null ==instances||instances.isEmpty()) {
				System.out.println("沒有相匹配的SysUsers實例對象！");
				instance = new SysUsers();
			} else {
				instance=instances.get(0);
				System.out.println("相匹配的SysUsers實例對象被找到！");
				}
			return instance;
		} catch (RuntimeException re) {
			System.out.println("findByUserAccount() 錯誤！");
			throw re;
		}
	}

}

SysUsersRolesDaoImpl.java

service層的實現

AuthoritiesResourcesManager.java

package org.joshua.ss.service;

import org.joshua.ss.dao.daoimpl.BaseDaoImpl;
import org.joshua.ss.entity.SysAuthoritiesResources;
import org.springframework.stereotype.Service;

/**
 *@author Joshua
 *@version 2011-12-20 下午02:19:19
 */
@Service("authoritiesResourcesManager")
public class AuthoritiesResourcesManager extends BaseDaoImpl<SysAuthoritiesResources,Long>{

}

下同,

這裏說明一下我沒有去操作對應的dao層而直接去操作通用dao,如果對應到裏沒有自定義的方法，或者沒有用到dao自定義的方法，可以直接繼承通dao，這樣也可省去dao層

這也是springside封裝通用dao將dao徹底省略掉，將增刪改查分頁等功能都封裝到通用dao中.

AuthorityManager.java
ResourceManager.java
RoleManager.java
RolesAuthoritiesManager.java
UserManager.java

這裏用到dao自定義的方法,所以注入dao

package org.joshua.ss.service;

import java.util.ArrayList;
import java.util.List;
import java.util.Set;

import javax.annotation.Resource;

import org.joshua.ss.dao.daoimpl.BaseDaoImpl;
import org.joshua.ss.dao.daoimpl.SysUsersDaoImpl;
import org.joshua.ss.entity.SysRolesAuthorities;
import org.joshua.ss.entity.SysUsers;
import org.joshua.ss.entity.SysUsersRoles;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.GrantedAuthorityImpl;
import org.springframework.stereotype.Service;

/**
 *@author Joshua
 *@version 2011-12-15 下午03:58:38
 * @param <SysUsers>
 */
@Service("userManager")
public class UserManager extends BaseDaoImpl<SysUsers,Long>{
	@Resource(name="hibernateTemplate")
	public HibernateTemplate  hibernateTemplate;
	
	@Resource(name="sysUsersDaoImpl")
	public SysUsersDaoImpl userDao;
	
	public SysUsersDaoImpl getUserDao() {
		return userDao;
	}
	public void setUserDao(SysUsersDaoImpl userDao) {
		this.userDao = userDao;
		
	}
	public SysUsers queryUnique(String id){
		return hibernateTemplate.get(SysUsers.class, id);
	}
	public List<GrantedAuthority> loadUserAuthoritiesByName(String username) {

		try {

			List<GrantedAuthority> auths = new ArrayList<GrantedAuthority>();
			List<String> authorityNameList = loadUserAuthorities(username);

			for (String authorityName : authorityNameList) {
				//??
				System.out.println(getClass().getName()+authorityName);
				GrantedAuthorityImpl authority = new GrantedAuthorityImpl(authorityName);
				auths.add(authority);
			}

			return auths;

		} catch (RuntimeException re) {
			throw re;
		}
	}

	public List<String> loadUserAuthorities(final String username) {
		try {

			List<String> authNameList = new ArrayList<String>();
			//根據用戶名獲得user
			SysUsers user = userDao.findByUserAccount(username);
			//根據user獲得roles
			Set<SysUsersRoles> usersRoles =	user.getSysUsersRoleses();
			for(SysUsersRoles usersrole:usersRoles){
				//更據roles獲得authenority 獲得auth_name
				Set<SysRolesAuthorities>  rolesAuthorities = usersrole.getSysRoles().getSysRolesAuthorities();
				for(SysRolesAuthorities roleAuthoritiy:rolesAuthorities){
					String authName = roleAuthoritiy.getSysAuthorities().getAuthorityName();
					authNameList.add(authName);
				}			
			}
			return authNameList;
		} catch (RuntimeException re) {
			System.out.println("find by authorities by username failed."
					+ re.getMessage());
			throw re;
		}

	}

spring security 中最重要的核心

MyAccessDecisionManager.java
MyFilterSecurityInterceptor.java
MyInvocationSecurityMetadataSource.java
MyUserDetails.java(自定義的SysUsers實現的接口，可以省掉，使用框架提供的User，

org.springframework.security.core.userdetails.User

)
MyUserDetailService.java

MyAccessDecisionManager.java

package org.joshua.ss;

import java.util.Collection;
import java.util.Iterator;

import org.springframework.security.access.AccessDecisionManager;
import org.springframework.security.access.AccessDeniedException;
import org.springframework.security.access.ConfigAttribute;
import org.springframework.security.access.SecurityConfig;
import org.springframework.security.authentication.InsufficientAuthenticationException;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.GrantedAuthority;
/**
 *AccessdecisionManager在Spring security中是很重要的。
 *
 *在驗證部分簡略提過了，所有的Authentication實現需要保存在一個GrantedAuthority對象數組中。 
 *這就是賦予給主體的權限。 GrantedAuthority對象通過AuthenticationManager
 *保存到 Authentication對象裏，然後從AccessDecisionManager讀出來，進行授權判斷。 
 *
 *Spring Security提供了一些攔截器，來控制對安全對象的訪問權限，例如方法調用或web請求。 
 *一個是否允許執行調用的預調用決定，是由AccessDecisionManager實現的。 
 *這個 AccessDecisionManager 被AbstractSecurityInterceptor調用，
 *它用來作最終訪問控制的決定。 這個AccessDecisionManager接口包含三個方法： 
 *
 void decide(Authentication authentication, Object secureObject,
 List<ConfigAttributeDefinition> config) throws AccessDeniedException;
 boolean supports(ConfigAttribute attribute);
 boolean supports(Class clazz);
 
  從第一個方法可以看出來，AccessDecisionManager使用方法參數傳遞所有信息，這好像在認證評估時進行決定。 
  特別是，在真實的安全方法期望調用的時候，傳遞安全Object啓用那些參數。 
  比如，讓我們假設安全對象是一個MethodInvocation。 
  很容易爲任何Customer參數查詢MethodInvocation，
  然後在AccessDecisionManager裏實現一些有序的安全邏輯，來確認主體是否允許在那個客戶上操作。 
  如果訪問被拒絕，實現將拋出一個AccessDeniedException異常。

  這個 supports(ConfigAttribute) 方法在啓動的時候被
  AbstractSecurityInterceptor調用，來決定AccessDecisionManager
  是否可以執行傳遞ConfigAttribute。 
  supports(Class)方法被安全攔截器實現調用，
  包含安全攔截器將顯示的AccessDecisionManager支持安全對象的類型。
