java Ldap域信息DN信息获取

1. 区别于AD域认证,添加基准的区别

// 其中value值为cn=manager,cn=lff,cn=com
// String domain = "cn=lff,cn=com"
env.put(Context.SECURITY_PRINCIPAL, "cn=" + uName + "," + domain);
// AD域
// env.put(Context.SECURITY_PRINCIPAL, uName);

2.数据获取

 public static List<LdapModel> returnLdapResult(Properties env, String sDomain) {
        List<LdapModel> ldapModels = new ArrayList<LdapModel>();
        try {
            DirContext ctx = new InitialLdapContext(env, null);
            String basedn = sDomain;
            String user_name = "";
            // 过滤条件
            String filter = "(&(objectClass=*)(uid=*))";
            String[] attrPersonArray = {"uid", "o"};
            SearchControls searchControls = new SearchControls();// 搜索控件
            searchControls.setSearchScope(2);// 搜索范围
            searchControls.setReturningAttributes(attrPersonArray);
            // 1.要搜索的上下文或对象的名称；2.过滤条件，可为null，默认搜索所有信息；3.搜索控件，可为null，使用默认的搜索控件
            NamingEnumeration<SearchResult> answer = ctx.search(basedn, filter.toString(), searchControls);
            while (answer.hasMoreElements()) {// 遍历结果集
                SearchResult result2 = (SearchResult) answer.next();
                String dnString = result2.getNameInNamespace();
                // dnString格式为："uid=dongyi,ou=people,dc=lff,dc=com"
                if (dnString.startsWith("uid")) {
                    LdapModel ldapModel = new LdapModel();
                    ldapModel.setAttrValue(dnString.split(",")[0].split("=")[1]);
                    ldapModel.setAttrName(dnString.split(",")[0].split("=")[1]);
                    ldapModel.setDn(dnString);
                    ldapModels.add(ldapModel);
                }
            }
            return ldapModels;
        } catch (NamingException e) {
            e.printStackTrace();
        }
        return ldapModels;
    }
