LDAP研究

一、ldap介紹

ldap是輕量級的目錄通路協定，重點是目錄通路協定，更為重點的是協定，好吧他是一個協定。也就是一個标準。

那麼實作這款協定的軟體其中有一款就是openldap.

二、安裝windows版本的openldap

下載下傳好windows版的openldap,一路下一步完成安裝。

重點在安裝根目錄裡也就是%OpenLDAP%下面的slapd.conf檔案

1. 預設的域名或者組織機構找到下面的代碼配置

suffix "dc=tcl,dc=com"

rootdn "cn=Manager,dc=tcl,dc=com"

rootpw 123456

2. 通路控制acl access開頭的配置這是通路權限配置

3.資料同步與複制配置

主伺服器配置這項

overlay syncprov

syncprov-nopresent TRUE

syncprov-reloadhint TRUE

從伺服器配置這項

syncrepl rid=0

provider=ldap://ldapmaster.symas.com:389

bindmethod=simple

binddn="cn=replicator,dc=symas,dc=com"

credentials=secret

searchbase="dc=symas,dc=com"

logbase="cn=accesslog"

logfilter="(&(objectClass=auditWriteObject)(reqResult=0))"

schemachecking=on

type=refreshAndPersist

retry="60 +"

syncdata=accesslog

4.注意啟動方式

我下載下傳的是2.4.39

啟動指令在 %OpenLDAP%run 目錄下的指令行

三、java調用

1.spring配置

<bean id="ldapSource" class="org.springframework.ldap.core.support.LdapContextSource">
		<property name="url" value="ldap://Dh-THINK:389" />
		<property name="base" value="DC=tcl,DC=com" />
		<property name="userDn" value="cn=manager,DC=tcl,DC=com" />
		<property name="password" value="123456" />
	</bean>
	
	<bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
		<constructor-arg ref="ldapSource" />
	</bean>

2.pom配置

<dependency>
		    <groupId>org.springframework.ldap</groupId>
		    <artifactId>spring-ldap-core</artifactId>
		    <version>2.0.2.RELEASE</version>
		    <exclusions>  
           <exclusion>      
                <groupId>org.springframework</groupId>          
                <artifactId>spring-beans</artifactId>  
           </exclusion>  
           <exclusion>      
                <groupId>org.springframework</groupId>          
                <artifactId>spring-core</artifactId>  
           </exclusion>  
           <exclusion>      
                <groupId>org.springframework</groupId>          
                <artifactId>spring-test</artifactId>  
           </exclusion>  
     </exclusions>  
		</dependency>

因為springmvc 是以包沖突，要排包。

3.增删改查操作

@Override
	public int CreatePerson(String dn, Person person) {
		try {
//dn不包括spring中配置的域名 
			ldapTemplate.bind(dn, null, buildAttributes(person));
			return 0;
		} catch (Exception e) {
			e.printStackTrace();
			return -1;
		}
	}

/**
	 * 構造人員屬性
	 * @param person
	 * @return
	 */
	private Attributes buildAttributes(Person person) {
		BasicAttribute ba = new BasicAttribute("objectclass");  
        ba.add("top"); //此處的person對應的是core.schema檔案中的objectClass：person  
        ba.add("person"); //此處的person對應的是core.schema檔案中的objectClass：person  
        Attributes attr = new BasicAttributes();  
        attr.put(ba);  
        
        attr.put("cn", person.getCn());  
        attr.put("sn", person.getSn()); 
        if(person.getTelephoneNumber()!=null&&!"".equals(person.getTelephoneNumber())){
        	attr.put("telephoneNumber", person.getTelephoneNumber());  
        }
        if(person.getUserPassword()!=null&&!"".equals(person.getUserPassword())){
        	attr.put("userPassword", person.getUserPassword());
        }
        if(person.getDescription()!=null&&!"".equals(person.getDescription())){
        	attr.put("description", person.getDescription());
        }
        if(person.getSeeAlso()!=null&&!"".equals(person.getSeeAlso())){
//        	attr.put("seeAlso", person.getSeeAlso()); 
        }
		return attr;
	}

@Override
	public int UpdatePerson(String dn, Person person) {
		try {
			ldapTemplate.rebind(dn, null, buildAttributes(person));
			return 0;
		} catch (Exception e) {
			return -1;
		}
	}

@Override
	public int deletePerson(String dn, Person person) {
		try {
			ldapTemplate.unbind(dn);
			return 0;
		} catch (Exception e) {
			return -1;
		}
	}

@Override
	public List<Person> findByOrganization(String oganizationName) {
		AndFilter filter = new AndFilter();
	      filter.and(new EqualsFilter("objectclass", "person"));
	      ContextMapper person = new PersonAttributesMapper();
	      return  ldapTemplate.search( "o="+oganizationName, filter.encode(),person);
	}

@Override
	public List findOrganizationAndPerson(String dn) {
//		Object object = ldapTemplate.lookup("o=product", new AttributesMapper() { public Object mapFromAttributes(Attributes attrs)throws NamingException{
//			return attrs.toString();}});
		OrFilter filter = new OrFilter();
	      filter.or(new LikeFilter("objectclass", "organizationalUnit"));
//	      filter.or(new LikeFilter("objectclass", "top"));
	      filter.or(new LikeFilter("objectclass", "organization"));
//	      filter.or(new LikeFilter("objectclass", "person"));
	      ContextMapper organizationUnit = new OrganizationUnitAttributesMapper();
		 return ldapTemplate.search( dn, filter.encode(), new ContextMapper() {

			@Override
			public Object mapFromContext(Object ctx) throws NamingException {
				DirContextAdapter context = (DirContextAdapter)ctx;
				return context;
			} });
	}

@Override
	public List<Person> findPersonListByDn(String dn) {
		OrFilter filter = new OrFilter();
	      filter.or(new LikeFilter("objectclass", "person"));
		 return ldapTemplate.search( dn, filter.encode(), new PersonAttributesMapper());
	}

public class PersonAttributesMapper implements ContextMapper<Person> {

	@Override
	public Person mapFromContext(Object ctx) throws NamingException {
		 DirContextAdapter context = (DirContextAdapter)ctx;
         Person person = new Person();
         person.setCn(context.getStringAttribute("cn"));
         person.setSn(context.getStringAttribute("sn"));
         person.setUserPassword(context.getStringAttribute("userPassword"));
         person.setDescription(context.getStringAttribute("description"));
         person.setSeeAlso(context.getStringAttribute("seeAlso"));
         person.setTelephoneNumber(context.getStringAttribute("telephoneNumber"));
         return person;
	}

}

接下來介紹一個解析樹的遞歸算法，輸入所有的機構人員資訊，解析出樹狀的機構層次

public JSONArray bulidTree(String dn){
		JSONArray jsonArray = new JSONArray();
		List<DirContextAdapter> list = ldapUtil.findOrganizationAndPerson(dn);
		String[] theDnArray = dn.split("=|,");
		for (DirContextAdapter ctx : list) {
			JSONObject json = new JSONObject();
			String dns = ctx.getDn().toString();
			String[] dnArray = dns.split("=|,");
			if(dnArray.length==theDnArray.length){
				json.put("id", dns);
				if("".endsWith(dnArray[0])){
					json.put("text", ctx.getStringAttribute("dc"));
				}else{
					json.put("text", ctx.getStringAttribute(dnArray[0]));
				}
				json.put("children", findChirld(dns));
				jsonArray.add(json);
			}else{
				
			}
		}
		return jsonArray;
	}
	public JSONArray findChirld(String dn){
		JSONArray jsonArray = new JSONArray();
		List<DirContextAdapter> list = ldapUtil.findOrganizationAndPerson(dn);
		String[] theDnArray = dn.split("=|,");
		for (DirContextAdapter ctx : list) {
			JSONObject json = new JSONObject();
			String dns = ctx.getDn().toString();
			String[] dnArray = dns.split("=|,");
			if(dnArray.length-theDnArray.length==2||dnArray.length-theDnArray.length==1){
				json.put("id", dns);
				json.put("text", ctx.getStringAttribute(dnArray[0]));
				json.put("children", findChirld(dns));
				jsonArray.add(json);
			}
		}
		return jsonArray;	
	}
