How to create Liferay web content in Java?

Creating a Web Content is easy via the UI.

But how to do add a new Web Content programmatically, in Java?

enter image description here

I must migrate data from a legacy system to Liferay 7, so I am writing a Java OSGI bundle to do so. No user interface.

In such cases it helps to look at the source code.

Also consider using an Upgrade Process. While your case is not really an update it sounds like a one time operation which you would ideally perform on startup.

I had a similar problem to solve in Liferay 6.2, but I believe you can solve yours using the same approach.

We built a "integration interface" (a simple Java Batch project to trigger the whole thing) that comunicates with the legacy system and with a Liferay REST Service (created using Liferay Service Builder).

Liferay provides you a Service API where you can handle some of its resources. To create a Journal Article (Web Content) you must invoke the Class JournalArticleLocalServiceUtil

Here is a sample code to create a Journal Article:

public static JournalArticle addJournalArticle(
        long userId, long groupId, String title, String contentEn)
        throws Exception {

    ServiceContext serviceContext = new ServiceContext();

    serviceContext.setAddGroupPermissions(true);
    serviceContext.setAddGuestPermissions(true);
    serviceContext.setScopeGroupId(groupId);
    serviceContext.setWorkflowAction(WorkflowConstants.ACTION_PUBLISH);
    Map<Locale, String> titleMap = new HashMap<Locale, String>();
    Map<Locale, String> descriptionMap = new HashMap<Locale, String>();

    titleMap.put(Locale.US, title);
    descriptionMap.put(Locale.US, title);


    try {
        JournalArticleLocalServiceUtil.deleteArticle(groupId, title, serviceContext);
    } catch (Exception ex) {
        System.out.println("Ignoring " + ex.getMessage());
    }

    String xmlContent = "<?xml version='1.0' encoding='UTF-8'?>" +
            "<root default-locale=\"en_US\" available-locales=\"en_US\">" +
                "<static-content language-id=\"en_US\">" +
                    "<![CDATA[" + contentEn + "]]>" +
                "</static-content>" +
            "</root>";

    JournalArticle article = JournalArticleLocalServiceUtil.addArticle(
            userId, groupId, 0, 
            0, 0, title, true, 
            JournalArticleConstants.VERSION_DEFAULT, titleMap, 
            descriptionMap, xmlContent, 
            "general", null, null, null, 
            1, 1, 2014, 0, 0,
            0, 0, 0, 0, 0, true, 
            0, 0, 0, 0, 0, true, 
            true, false, null, null, 
            null, null, serviceContext);

    return article;
}

But you must to improve it to put the correct user permissions, categories, tags and etc.
