How to get RoleId using Role Name in liferay?

问题

Is there any method where I can get the RoleId using Role Name? I have created some custom roles on my portal, like "Project Manager", "Client" and "Delivery Head". Now I need to get the respective role of these custom roles programmatically using Role Name.

Any suggestions?

回答1:

You can use RoleLocalServiceUtil.getRole(companyId, name) method to get the role object (instance of RoleModel). If you need the id, call role.getRoleId().

Company id can be obtained by calling ThemeDisplay.getCompanyId().

回答2:

public long getRoleIdByName(String roleName) throws Exception {
    if (roleName != null && !roleName.isEmpty()) {
        for (Role role : RoleLocalServiceUtil.getRoles(0, RoleLocalServiceUtil.getRolesCount())) {
            if (role.getName().equals(roleName)) {
                return role.getRoleId();
            }
        }
    }
    return -1;
}
