单点登录之apacheds之springMVC下操作使用

2017-11-02

单点登录之apacheds之springMVC下操作使用。

1、添加支持的jar包
spring-ldap-core-2.0.2.RELEASE.jar
2、spring中配置


    
    
    
    
    
    
        
    
    
        
    

可是使用多数据源,多数据源配置复制上面配置信息,修改bean的id即可,在注解引用的时候,标明是那个ldap的

3、创建实体bean

package com.bean.ldap;

import java.util.ArrayList;

import com.model.BaseModel;

public class UserBean extends BaseModel {

    private String cn;
    private String oldCn;
    //返回cn的集合
    private ArrayList cns;
    private String childCn;
    private String sn;
    private String grandson;
    private String uid;
    private String userPassword;
    private String description;
    //返回属性descriptions的集合
    private ArrayList descriptions;
    private String ou;
    private String st;
    public String getSt() {
        return st;
    }
    public void setSt(String st) {
        this.st = st;
    }
    public ArrayList getDescriptions() {
        return descriptions;
    }
    public void setDescriptions(ArrayList descriptions) {
        this.descriptions = descriptions;
    }
    public String getDescription() {
        return description;
    }
    public void setDescription(String description) {
        this.description = description;
    }
    public String getCn() {
        return cn;
    }
    public void setCn(String cn) {
        this.cn = cn;
    }
    public String getSn() {
        return sn;
    }
    public void setSn(String sn) {
        this.sn = sn;
    }
    public String getUid() {
        return uid;
    }
    public void setUid(String uid) {
        this.uid = uid;
    }
    public String getUserPassword() {
        return userPassword;
    }
    public void setUserPassword(String userPassword) {
        this.userPassword = userPassword;
    }
    public String getChildCn() {
        return childCn;
    }
    public void setChildCn(String childCn) {
        this.childCn = childCn;
    }
    public String getOu() {
        return ou;
    }
    public void setOu(String ou) {
        this.ou = ou;
    }
    public ArrayList getCns() {
        return cns;
    }
    public void setCns(ArrayList cns) {
        this.cns = cns;
    }

    public String getOldCn() {
        return oldCn;
    }
    public void setOldCn(String oldCn) {
        this.oldCn = oldCn;
    }
    public String getGrandson() {
        return grandson;
    }
    public void setGrandson(String grandson) {
        this.grandson = grandson;
    }
}

4、创建bean后创建返回对象作为ldap查询返回类型
创建UserBeanLdapMapper.java 作为范围类型对象,并继承AttributesMapper

package com.mapper.ldap;
import java.util.ArrayList;
import javax.naming.NamingEnumeration;
import javax.naming.NamingException;
import javax.naming.directory.Attributes;
import org.springframework.ldap.core.AttributesMapper;
import com.bean.ldap.UserBean;
public class UserBeanLdapMapper implements AttributesMapper{
    @Override
public Object mapFromAttributes(Attributes attr) throws NamingException {           
            //创建UserBean 对象
            UserBean person = new UserBean();
//如果sn不为空设置sn  
            if(attr.get("sn")!=null){
                  person.setSn(attr.get("sn").get().toString());
            }  
            if(attr.get("ou")!=null){
                  person.setOu(attr.get("ou").get().toString());
            }  
            if(attr.get("st")!=null){
                  person.setSt(attr.get("st").get().toString());
            }  
//设置cn,通过attr.get("cn").getAll()获取所有的cn返回的是枚举类型,创建list集合,并通过while循环,添加到list集合中
            if(attr.get("cn")!=null){
            ArrayList list=new ArrayList();
              NamingEnumeration all = (NamingEnumeration) attr.get("cn").getAll();
              while(all.hasMoreElements()){
                 list.add(all.nextElement());
              }
              person.setCns(list);
              person.setCn(attr.get("cn").get().toString());
            }
            if(attr.get("uid")!=null)
            person.setUid((String)attr.get("uid").get()); 
            if(attr.get("description")!=null){
            ArrayList list=new ArrayList();
            NamingEnumeration all = (NamingEnumeration) attr.get("description").getAll();
            while(all.hasMoreElements()){
                list.add(all.nextElement());}
            person.setDescriptions(list); 
            person.setDescription(attr.get("description").get().toString());
            }
            return person;  
    } 

}

5、接下来就是创建工具累对ldap的增删修改查询了,在这里注意一些子查询,子子节点(孙节点查询也在该方法内)
这里包含了实际开发中的一些业务逻辑,在参考的时候多多注意,根据自己的需求修改。

package com.dao;

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

import javax.annotation.Resource;
import javax.naming.directory.Attributes;
import javax.naming.directory.BasicAttribute;
import javax.naming.directory.BasicAttributes;
import javax.naming.directory.DirContext;
import javax.naming.directory.ModificationItem;
import javax.naming.directory.SearchControls;

        return ldapTemplate2;
    }

    public void setLdapTemplate2(LdapTemplate ldapTemplate2) {
        this.ldapTemplate2 = ldapTemplate2;
    }

    /**

     */
    @SuppressWarnings("deprecation")
    private DistinguishedName getDn(String parentCn, String childCn) {
        // 得到根目录,也就是配置文件中配置的ldap的根目录
        DistinguishedName newContactDN = new DistinguishedName();
        // 添加cn,即使得该条记录的dn为"cn=cn,根目录",例如"cn=abc,dc=testdc,dc=com"
        newContactDN.append("cn", parentCn);
        if(childCn!=null&&!childCn.equals(""))
        newContactDN.append("cn", childCn);
        return newContactDN;
    }

    @SuppressWarnings("deprecation")

        return newContactDN;
    }
    /**
