在实际应用中,开发者有时需要将Web资源授权信息(角色与授权资源之间的定义)存放在RDBMS中,以便更好的管理。事实上,我觉得一般的企业应用都应当如此,因为这样可以使角色和Web资源的管理更灵活,更自由。那么,我们应当如何实现这个需求呢?在接下来的内容当中,我们将一一解说。
我们都知道,一般Web资源授权信息的配置类似如下代码:
- <bean id="filterInvocationInterceptor"
- class="org.acegisecurity.intercept.web.FilterSecurityInterceptor">
- ……
- <property name="objectDefinitionSource">
- <value>
- <![CDATA[
- CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISON
- PATTERN_TYPE_APACHE_ANT
- /secure/**=ROLE_SUPERVISOR
- /authenticate/**=ROLE_USER,ROLE_SUPERVISOR
- /**=IS_AUTHENTICATED_ANONYMOUSLY
- ]]>
- </value>
- </property>
- </bean>
<bean id="filterInvocationInterceptor" class="org.acegisecurity.intercept.web.FilterSecurityInterceptor"> …… <property name="objectDefinitionSource"> <value> <![CDATA[ CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISON PATTERN_TYPE_APACHE_ANT /secure/**=ROLE_SUPERVISOR /authenticate/**=ROLE_USER,ROLE_SUPERVISOR /**=IS_AUTHENTICATED_ANONYMOUSLY ]]> </value> </property> </bean>
objectDefinitionSource 属性定义发Web资源授权信息(角色与授权资源之间的关系)
objectDefinitionSource 属性指定了”PATTERN_TYPE_APACHE_ANT”,即希望启用Apache Ant路径风格的URL匹配模式,则FilterInvocationDefinitionSourceEditor会实例化PathBasedFilterInvocationDefinitionMap实例。如果未指定这一字符串,即希望采用默认的正是表达式,则RegExpBasedFilterInvocationDefinitionMap会被实例化。注意,PathBasedFilterInvocationDefinitionMap和RegExpBasedFilterInvocationDefinitionMap都是FilterInvocationDefinitionSource的实现类。
当Web容器装载Acegi时,Spring会自动找到FilterInvocationDefinitionSourceEditor属性编辑器,并采用它解析上述Web资源授权信息。由于FilterInvocationDefinitionSource同FilterInvocationDefinitionSourceEditor处在同一个Java包中,因此开发者不用显式注册这一属性编辑器,Spring会透明地为开发者考虑到这一切。
为了能够通过RDBMS维护Web资源授权信息,我们必须提供自身的FilterInvocationDefinitionSource实现类。
Acegi 安全系统需要记录一些配置信息,这些配置信息用于各种可能的请求。为了存储针对各种不同请求的各种安全配置,就要使用配置属性。在实现上配置属性通过ConfigAttribute接口来表示。SecurityConfig是ConfigAttribute接口的一个具体实现,它简单地把配置属性当作一个串(String)来存储。
与特定请求相联系的ConfigAttributes 集合保存在ConfigAttributeDefinition中。这个类只是一个简单的ConfigAttributes存储器,并不做其它特别的处理。
当安全性拦截器收到一个请求时,它需要判断使用哪些配置属性。换句话说,它需要找到用于这种请求的ConfigAttributeDefinition.这种判别是通过ObjectDefinitionSource接口来处理的.这个接口提供的主要方法是 public ConfigAttributeDefinition getAttributes(Object object),其中的Object 就是要保护的安全对象。因为安全对象包含了请求的细节,所以ObjectDefinitionSource实现类将能够抽取它所需要的细节来检查相关的ConfigAttributeDefinition。
1、 增加Web资源授权信息表
- create table webresdb(
- id bigint not null primary key,
- url varchar(60) not null,
- roles varchar(100) not null
- );
- INSERT INTO WEBRESDB VALUES(1,'/secure/**','ROLE_SUPERVISOR')
- INSERT INTO WEBRESDB VALUES(2,'/authenticate/**','ROLE_USER,ROLE_SUPERVISOR')
- INSERT INTO WEBRESDB VALUES(3,'/**','IS_AUTHENTICATED_ANONYMOUSLY')
create table webresdb( id bigint not null primary key, url varchar(60) not null, roles varchar(100) not null ); INSERT INTO WEBRESDB VALUES(1,'/secure/**','ROLE_SUPERVISOR') INSERT INTO WEBRESDB VALUES(2,'/authenticate/**','ROLE_USER,ROLE_SUPERVISOR') INSERT INTO WEBRESDB VALUES(3,'/**','IS_AUTHENTICATED_ANONYMOUSLY')
2、增加类似于EntryHolder的辅助类RdbmsEntryHolder
通过分析PathBasedFilterInvocationDefinitionMap类,我们发现,对于每行Web 资源授权需求,比如“/secure/**=ROLE_SUPERVISOR”,它会借助于内部类EntryHolder存储各行内容。EntryHolder暴露了antPath和configAttributeDefinition属性,前者存储类似“/secure/**”的内容,而后者会通过configAttributeDefinition对象存储类似“ROLE_USER,ROLE_SUPERVISOR”的内容。在ConfigAttributeDefinition对象内部,它将各个角色拆分开,并分别借助SecurityConfig对象存储它们,即ROLE_USER和ROLE_SUPERVISOR,从而保存在configAttributes私有变量中。
在此,我们提供了类似于EntryHolder的辅助类:
- public class RdbmsEntryHolder implements Serializable {
- private static final long serialVersionUID = 2317309106087370323L;
- // 保护的URL模式
- private String url;
- // 要求的角色集合
- private ConfigAttributeDefinition cad;
- public String getUrl() {
- return url;
- }
- public ConfigAttributeDefinition getCad() {
- return cad;
- }
- public void setUrl(String url) {
- this.url = url;
- }
- public void setCad(ConfigAttributeDefinition cad) {
- this.cad = cad;
- }
- }
public class RdbmsEntryHolder implements Serializable { private static final long serialVersionUID = 2317309106087370323L; // 保护的URL模式 private String url; // 要求的角色集合 private ConfigAttributeDefinition cad; public String getUrl() { return url; } public ConfigAttributeDefinition getCad() { return cad; } public void setUrl(String url) { this.url = url; } public void setCad(ConfigAttributeDefinition cad) { this.cad = cad; } }
3、增加从RDBMS装载所有的Web资源授权信息的类
- public class RdbmsSecuredUrlDefinition extends MappingSqlQuery{
- protected static final Log logger = LogFactory.getLog(RdbmsSecuredUrlDefinition.class);
- protected RdbmsSecuredUrlDefinition(DataSource ds) {
- super(ds, Constants.ACEGI_RDBMS_SECURED_SQL);
- logger.debug("进入到RdbmsInvocationDefinition构建器中.........");
- compile();
- }
- /**
- * convert each row of the ResultSet into an object of the result type.
- */
- protected Object mapRow(ResultSet rs, int rownum)
- throws SQLException {
- logger.debug("抽取webresdb中的记录.........");
- RdbmsEntryHolder rsh = new RdbmsEntryHolder();
- // 设置URL
- rsh.setUrl(rs.getString(Constants.ACEGI_RDBMS_SECURED_URL).trim());
- ConfigAttributeDefinition cad = new ConfigAttributeDefinition();
- String rolesStr = rs.getString(Constants.ACEGI_RDBMS_SECURED_ROLES).trim();
- // commaDelimitedListToStringArray:Convert a CSV list into an array of Strings
- // 以逗号为分割符, 分割字符串
- String[] tokens =
- StringUtils.commaDelimitedListToStringArray(rolesStr); // 角色名数组
- // 构造角色集合
- for(int i = 0; i < tokens.length;++i)
- cad.addConfigAttribute(new SecurityConfig(tokens[i]));
- //设置角色集合
- rsh.setCad(cad);
- return rsh;
- }
- }
public class RdbmsSecuredUrlDefinition extends MappingSqlQuery{ protected static final Log logger = LogFactory.getLog(RdbmsSecuredUrlDefinition.class); protected RdbmsSecuredUrlDefinition(DataSource ds) { super(ds, Constants.ACEGI_RDBMS_SECURED_SQL); logger.debug("进入到RdbmsInvocationDefinition构建器中........."); compile(); } /** * convert each row of the ResultSet into an object of the result type. */ protected Object mapRow(ResultSet rs, int rownum) throws SQLException { logger.debug("抽取webresdb中的记录........."); RdbmsEntryHolder rsh = new RdbmsEntryHolder(); // 设置URL rsh.setUrl(rs.getString(Constants.ACEGI_RDBMS_SECURED_URL).trim()); ConfigAttributeDefinition cad = new ConfigAttributeDefinition(); String rolesStr = rs.getString(Constants.ACEGI_RDBMS_SECURED_ROLES).trim(); // commaDelimitedListToStringArray:Convert a CSV list into an array of Strings // 以逗号为分割符, 分割字符串 String[] tokens = StringUtils.commaDelimitedListToStringArray(rolesStr); // 角色名数组 // 构造角色集合 for(int i = 0; i < tokens.length;++i) cad.addConfigAttribute(new SecurityConfig(tokens[i])); //设置角色集合 rsh.setCad(cad); return rsh; } }
这样,我们可以利用RdbmsSecuredUrlDefinition将webresdb中的各行记录组装成RdbmsEntryHolder对象,进而返回RdbmsEntryHolder集合给调用者。
4、增加FilterInvocationDefinitionSource的实现类
- /**

- */
- public class RdbmsFilterInvocationDefinitionSource extends JdbcDaoSupport
- implements FilterInvocationDefinitionSource {
- protected static final Log logger = LogFactory.getLog(RdbmsFilterInvocationDefinitionSource.class);
- private RdbmsSecuredUrlDefinition rdbmsInvocationDefinition;

- private Ehcache webresdbCache;

- public ConfigAttributeDefinition getAttributes(Object object)
- throws IllegalArgumentException {
- if ((object == null) || !this.supports(object.getClass())) {
- throw new IllegalArgumentException("抱歉,目标对象不是FilterInvocation类型");
- }
- // 抽取出待请求的URL
- String url = ((FilterInvocation) object).getRequestUrl();
- logger.info("待请示的URL: " + url);
- // 获取所有RdbmsEntryHolder列表(url与角色集合对应列表)
- List list = this.getRdbmsEntryHolderList();
- if (list == null || list.size() == 0)
- return null;
- // 去掉待请求url参数信息
- int firstQuestionMarkIndex = url.indexOf("?");
- if (firstQuestionMarkIndex != -1) {
- url = url.substring(0, firstQuestionMarkIndex);
- }
- Iterator iter = list.iterator();
- // 循环判断用户是否有权限访问当前url, 有则返回ConfigAttributeDefinition(角色集合)
- while (iter.hasNext()) {
- RdbmsEntryHolder entryHolder = (RdbmsEntryHolder) iter.next();
- // 判断当前访问的url是否符合entryHolder.getUrl()模式, 即判断用户是否有权限访问当前url
- // 如url="/secure/index.jsp", entryHolder.getUrl()="/secure/**", 则有权限访问
- boolean matched = pathMatcher.match(entryHolder.getUrl(), url);
- if (logger.isDebugEnabled()) {
- logger.debug("匹配到如下URL: '" + url + ";模式为 "
- + entryHolder.getUrl() + ";是否被匹配:" + matched);
- }
- // 如果在用户所有被授权的URL中能找到匹配的, 则返回该ConfigAttributeDefinition(角色集合)

- }
- }

- public Iterator getConfigAttributeDefinitions() {

由于RdbmsFilterInvocationDefinitionSource是针对Web资源的,因此它实现的supports()方法需要评估FilterInvocation对象。另外,为了减少同RDBMS的交互次数,我们启用了Spring EhCache服务。
5、通过Spring DI注入RdbmsFilterInvocationDefinitionSource

6、运行说明
下载源代码,我提供了相应脚本,存放在Acegi8WebRoot
dbms目录下。
1)、在rdbms目录下运行server.bat文件,启动hsqldb数据库。关于hsqldb的使用说明,请参考“菜鸟-手把手教你把Acegi应用到实际项目中(6)” http://zhanjia.iteye.com/blog/258282
2)、运行Acegi8项目
3)、用户名为javaee、qiuzj,密码为password
至此,我们此节所讲的内容已结束,大家可以下载源代码以便调试。另外,代码中还提供了另一个版本的实现类RdbmsFilterInvocationDefinitionSourceVersion2,它继承了AbstractFilterInvocationDefinitionSource,在一定程序上减少了代码量,朋友们可以自行研究。
