近段时间接触了一个项目,用户认证部分是通过域认证的方式,我们的项目是用Java语言开发的,在以前从未接触过这方面的知识,首先了解了这个域的概念,然后去看这个域到低是个什么样的东西.登录到域服务器,一看,哦,原来是一活动目录(Active Directory),这下看到了它的全部面目,通过查询,还看到了我的名字也在这个域服务器上,顿时感觉到很新奇,再后来又知道了,域服务器除了AD,之外还有专门的服务器Open Ldap,还有其它的几个,在这里我就不写了,基本知道了这些东西后,通过查资料,知道了spring ldap 已很好的支持对域服务器的访问,我们的项目也采用了Spring 框架,于是下载了Spring-Ldap 1.3 这个版本的所有文档,开始研究,基本上还都能看懂,最主要是有例子,最终也通过写程序实现了,但我想通过Spring 的配置来实现,但在文档中没有找到相关说明,用户登录的信息肯定是动态的,如果只把用户名和密码配置在Spring 的配置文件中,通过这个配置也能查询其它用户信息,但毕竟不是最好的办法,后来通过仔细的研究,发现可以通过实现AuthenticationSource接口,动态的注入用户名和密码,总体的实现方式如下:
-
- <bean id="ContextSource" class="org.springframework.ldap.core.support.LdapContextSource">
- <property name="url" value="ldap://ptr.petrochina:389" />
- <property name="base" value="dc=ptr,dc=petrochina" />
- <property name="referral" value="follow"></property> //让我折腾了很久的地方
- <property name="authenticationSource" ref="AuthenticationSource" />
- </bean>
- <bean id="AuthenticationSource"
- class="org.springframework.ldap.authentication.DefaultValuesAuthenticationSourceDecorator">
- <property name="target" ref="SpringSecurityAuthenticationSource" />
- <property name="defaultUser" value="***@petrochina.com.cn" />
- <property name="defaultPassword" value="***" />
- </bean>
- <bean id="SpringSecurityAuthenticationSource"
- class="com.BRM.right.component.LdapAuthenticationSource" />
- <bean id="LdapTemplate" class="org.springframework.ldap.core.LdapTemplate">
- <constructor-arg ref="ContextSource" />
- </bean>
-
-
-
实现AuthenticationSource接口
- package com.BRM.right.component;
-
- import org.springframework.ldap.core.AuthenticationSource;
-
- public class LdapAuthenticationSource implements AuthenticationSource {
-
- private static ThreadLocal login = new ThreadLocal();
- private static ThreadLocal password = new ThreadLocal();
-
- public static void setLogin(String login) {
- LdapAuthenticationSource.login.set(login);
- }
-
- public static void setPassword(String password) {
- LdapAuthenticationSource.password.set(password);
- }
-
- public String getPrincipal() {
- String login = (String) LdapAuthenticationSource.login.get();
- if (login == null || "".equals(login)) {
- return null;
- }
- return login;
- }
-
- public String getCredentials() {
- String password = (String) LdapAuthenticationSource.password.get();
- if (password == null || "".equals(password)) {
- return null;
- }
- return password;
- }
-
- }
-
记住要设置值:
- LdapAuthenticationSource.setLogin(loginForm.getUserName()+"@petrochina.com.cn");
- LdapAuthenticationSource.setPassword(loginForm.getPassword());
验证用户密码是否正确的方法:
- AndFilter filter = new AndFilter();
- filter.and(new EqualsFilter("userprincipalname", userprincipalname));
- return ldapTemplate.authenticate("", filter.toString(), password);
由用户查询结果:
- public List findInfoByUserPrincipalName(String userprincipalname) {
- AndFilter filter = new AndFilter();
-
- filter.and(new EqualsFilter("userprincipalname", userprincipalname));
-
- return ldapTemplate.search(DistinguishedName.EMPTY_PATH, filter
- .encode(), new LdapUserMapper());
- }
实现接口AttributesMapper
- private class LdapUserMapper implements AttributesMapper {
- public Object mapFromAttributes(Attributes attrs) {
- LdapUserBean user = new LdapUserBean();
-
- String yhm = "", yhmqc = "", email = "", dn = "", szdw = "";
- String[] memberOf = null;
- try {
- yhm = (String) attrs.get("samaccountname").get();
- } catch (Exception e) {
-
- }
- try {
- yhmqc = (String) attrs.get("cn").get();
- } catch (Exception e) {
-
- }
-
- try {
- email = (String) attrs.get("mail").get();
- } catch (Exception e) {
-
- }
- try {
- dn = (String) attrs.get("distinguishedname").get();
- } catch (Exception e) {
-
- }
- try {
- szdw = (String) attrs.get("company").get();
- } catch (Exception e) {
-
- }
- try {
- NamingEnumeration temp = attrs.get("memberof").getAll();
- List list = new ArrayList();
- while (temp.hasMoreElements()) {
- String t = temp.nextElement().toString();
- list.add(t);
- }
-
- if (list != null) {
- memberOf = (String[]) list.toArray(new String[0]);
- }
-
- } catch (Exception e) {
-
- }
-
- user.setYhm(yhm);
- user.setYhmqc(yhmqc);
- user.setEmail(email);
- user.setDisginguishedname(dn);
- user.setSzdw(szdw);
- user.setMemberof(memberOf);
- return user;
- }
- }
-
- public class LdapUserBean {
-
- private String yhm;
-
- private String yhmqc;
-
- private String szdw;
-
- private String email;
-
- private String bz;
-
-
- private String disginguishedname;
-
-
-
-
-
-
- private String[] memberof;
-
- private String userprincipalname;
-
- public String getYhm() {
- return yhm;
- }
-
- public void setYhm(String yhm) {
- this.yhm = yhm;
- }
-
- public String getYhmqc() {
- return yhmqc;
- }
-
- public void setYhmqc(String yhmqc) {
- this.yhmqc = yhmqc;
- }
-
- public String getSzdw() {
- return szdw;
- }
-
- public void setSzdw(String szdw) {
- this.szdw = szdw;
- }
-
- public String getEmail() {
- return email;
- }
-
- public void setEmail(String email) {
- this.email = email;
- }
-
- public String getBz() {
- StringBuffer bs=new StringBuffer();
- for(int i=0;i<memberof.length;i++){
- bs.append(memberof[i]);
- }
- bs.append("用户所在路径:"+disginguishedname);
- this.bz = bs.toString();
- return bz;
- }
-
- public void setBz(String bz) {
- this.bz=bz;
- }
-
- public String getDisginguishedname() {
- return disginguishedname;
- }
-
- public void setDisginguishedname(String disginguishedname) {
- this.disginguishedname = disginguishedname;
- }
-
- public String[] getMemberof() {
- return memberof;
- }
-
- public void setMemberof(String[] memberof) {
- this.memberof = memberof;
- }
-
- public String getUserprincipalname() {
- return userprincipalname;
- }
-
- public void setUserprincipalname(String userprincipalname) {
- this.userprincipalname = userprincipalname;
- }
-
-
- }

罗列了这么多代码,也算是自己作一个记录吧.当然了还有很多实现方式,只不过这种实现方式自我感觉很良好.总体来说吧自己水平有限,请看到这文章的大侠们多提意见.
