Import users into Liferay

If you’re using Liferay, and not using LDAP, you will probably face into the same problem I did – how to import a large amount of users without manually adding them to the system.

So, loving automation, I’ve decided to create a simple Portlet that does just that.

  1. Create a new Dynamic Web App in Eclipse.
  2. Configure all necessary deployment files (liferay-portlet.xml, portlet.xml, web.xml etc)
  3. Create a new User class:
    package com.tona.liferay.web;public class User {
    private String firstName;
    private String lastName;
    private String email;
    private String phoneNo;
    private String screenName;
    private String password;
    public String getEmail() {
    return email;
    public void setEmail(String email) { = email;
    public String getPhoneNo() {
    return phoneNo;
    public void setPhoneNo(String phoneNo) {
    this.phoneNo = phoneNo;
    public String getFirstName() {
    return firstName;
    public void setFirstName(String firstName) {
    this.firstName = firstName;
    public String getLastName() {
    return lastName;
    public void setLastName(String lastName) {
    this.lastName = lastName;
    public String getScreenName() {
    return screenName;
    public void setScreenName(String screenName) {
    this.screenName = screenName;
    public String getPassword() {
    return password;
    public void setPassword(String password) {
    this.password = password;
    public User(String line) {
    String[] tokens = line.split(",");
    String screenName = getFirstName() + getLastName().substring(0, 3);
    setPassword(getScreenName() + "123");
    public User() {
  4. Create the portlet itself:
    package com.tona.liferay.web;import;
    import java.util.ArrayList;
    import java.util.List;
    import java.util.Locale;
    import java.util.logging.Level;
    import java.util.logging.Logger;
    import javax.portlet.ActionRequest;
    import javax.portlet.ActionResponse;
    import javax.portlet.PortletException;
    import com.liferay.portal.model.Company;
    import com.liferay.portal.service.CompanyLocalServiceUtil;
    import com.liferay.portal.service.UserLocalServiceUtil;
    import com.liferay.util.bridges.mvc.MVCPortlet;
    public class ImportUsersPortlet extends MVCPortlet {
    public void importUsers(ActionRequest actionRequest,
    ActionResponse actionResponse) throws IOException, PortletException {
    String fileName = actionRequest.getParameter("fileName");
    BufferedReader fr = new BufferedReader(new FileReader(fileName));
    Listusers = new ArrayList();
    String line;
    while ((line = fr.readLine()) != null) {
    users.add(new User(line));
    // We now have the user list
    com.liferay.portal.service.ServiceContext context = new com.liferay.portal.service.ServiceContext();
    long companyId = 0;
    try {
    Company company = CompanyLocalServiceUtil.getCompanies().get(0);
    companyId = company.getCompanyId();
    for (User user : users) {
    try {
    UserLocalServiceUtil.addUser(0, companyId, false,
    user.getPassword(), user.getPassword(), false, user.getScreenName(),
    user.getEmail(), 0, "", Locale.getDefault(),
    user.getFirstName(), "", user.getLastName(), 0, 0,
    true, 1, 1, 1970, null, null, null, null, null, false,
    } catch (Exception e) {
    } catch (Exception e) {
  5. Create a WAR file and deploy it in Liferay
  6. Note that the portlet does not upload the CSV file – and expects it to exist on the Liferay server itself
  7. You can of course change the algorithm of the screen-name and password creation, by changing the User constructor method.
