Get the user roles in programtically :

if we want to get the roles of postlogin add the below code:
------------------------------------------------------------------------
HttpServletRequest request;
HttpServletResponse response;

HttpSession session = request.getSession(false);

User user = PortalUtil.getUser(request);
if(Validator.isNotNull(user)){

List<Role> userRoles = RoleLocalServiceUtil.getUserRoles(user.getUserId());
Map<String, String> rolesMap = new HashMap<String, String>();
for (Role role : userRoles) {
rolesMap.put(role.getName(), role.getName());
}

}
session.setAttribute("roles", rolesMap);

Get the roels in appropriate portlet:
============================

HashMap<String, String> rolesMap = (HashMap<String, String>) portletSession.getAttribute("roles",
PortletSession.APPLICATION_SCOPE);

Expando Values.

Get the custom attribute values or Expando values :

======================================

User user = null;

ThemeDisplay themeDisplay = (ThemeDisplay) req.getAttribute(WebKeys.THEME_DISPLAY);

user = themeDisplay.getUser();

long curLoginUserid = user.getUserId();

ExpandoValue expandoMobileNumberValue =  ExpandoValueLocalServiceUtil.getValue(themeDisplay.getCompanyId(), User.class.getName(), ExpandoTableConstants.DEFAULT_TABLE_NAME, "contact-number-mobile", curLoginUserid);

ExpandoValue expandoUserCountryValue =  ExpandoValueLocalServiceUtil.getValue(themeDisplay.getCompanyId(), User.class.getName(), ExpandoTableConstants.DEFAULT_TABLE_NAME, "User Country", curLoginUserid);

String curLoginMobileNumber = expandoMobileNumberValue.getData();

String curLoginUserCountry = " ";

if(Validator.isNotNull(expandoUserCountryValue))

curLoginUserCountry = expandoUserCountryValue.getData();

Update expando values of login user:

============================

ThemeDisplay themeDisplay = (ThemeDisplay) req.getAttribute(WebKeys.THEME_DISPLAY);

User loginUser = themeDisplay.getUser();

User user = null;

ThemeDisplay themeDisplay = (ThemeDisplay) req.getAttribute(WebKeys.THEME_DISPLAY);

user = themeDisplay.getUser();

long curLoginUserid = user.getUserId();

String updateCompanyName = UpdateForm.getCompanyName();

ExpandoValue expandoValue =  ExpandoValueLocalServiceUtil.getValue(themeDisplay.getCompanyId(), User.class.getName(), ExpandoTableConstants.DEFAULT_TABLE_NAME, "company-name", userId);

expandoValue.setData(updateCompanyName);

ExpandoValueLocalServiceUtil.updateExpandoValue(expandoValue);

User details add and get the programatically.

Add the user details in Programatically.
=============================

ThemeDisplay themeDisplay = (ThemeDisplay) req.getAttribute(WebKeys.THEME_DISPLAY);
User user = null;

String emailaddress = ParamUtil.getString(“emailaddress”);

String screenName = ParamUtil. getString(“screenname”);

List<User> users = UserLocalServiceUtil.getUsers(0, UserLocalServiceUtil.getUsersCount());

for(User user : users) {

    if(emailAddress.equalsIgnoreCase(user.getEmailAddress()) || screenName.equalsIgnoreCase(user.getScreenName())){

            System.out.println(“user is already exists ”);

             }

             else{

             }

         }

               long[] groupIds = {themeDisplay.getLayout().getGroupId()};

               ServiceContext serviceContext = ServiceContextFactory.getInstance(User.class.getName(), req);

serviceContext.setScopeGroupId(themeDisplay.getLayout().getGroupId());

long[] roleIds = {};

long[] organisationIds = {};

long[] userGroupIds = {};

user =UserLocalServiceUtil.addUser(20199, themeDisplay.getCompanyId(), true, "", "", false, screenNam, emailAddrs,facebookId, "", Locale.ENGLISH, firstName, "", lastNameUsr, 1, 1, true, 10, 10, 1900, "", groupIds, roleIds, organisationIds, userGroupIds, true, serviceContext);

Get the current user login details:

=============================

User user = null;

ThemeDisplay themeDisplay = (ThemeDisplay) req.getAttribute(WebKeys.THEME_DISPLAY);

user = themeDisplay.getUser();

long curLoginUserid = user.getUserId();

Update the current user login details:

===========================

String email = UpdateForm.getEmailAddress();

String updateScreenName = UpdateForm.getScreenName();

String updateFstName = UpdateForm.getFisrtName();

String updateLastName = UpdateForm.getLastName();

String updateCompanyName = UpdateForm.getCompanyName();

                             

ThemeDisplay themeDisplay = (ThemeDisplay) req.getAttribute(WebKeys.THEME_DISPLAY);

User loginUser = themeDisplay.getUser();

loginUser.setEmailAddress(email);

loginUser.setUserId(userId);

loginUser.setFirstName(updateFstName);

loginUser.setLastName(updateLastName);

loginUser.setScreenName(updateScreenName);

UserLocalServiceUtil.updateUser(loginUser);
