如何创建结构和结构在Liferay 6中以编程方式编写模板

问题描述

我需要通过Java代码以编程方式创建结构和模板.我使用了以下代码段.

I need to create the Structure and Template progrmatically through java code.I used following code snippets.

结构:

public void createStructure(String userName,long userId){
        log_.info("Inside create structure ");
        long structureId=115203;
        DDMStructure ddmStructure=DDMStructureLocalServiceUtil.createDDMStructure(structureId);
        ddmStructure.setName("MigrationStructure");
        ddmStructure.setDescription("This Structure created programatically");
        ddmStructure.setUserId(userId);
        ddmStructure.setUserName(userName);
        File fXmlFile = new File("D:/FilesDataMigration/structure.xml");        
        try {           
            Document document = SAXReaderUtil.read(fXmlFile);
            ddmStructure.setDocument(document);
            DDMStructureLocalServiceUtil.addDDMStructure(ddmStructure);
        }catch (DocumentException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (SystemException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }   
        log_.info("Inside create structure done");
    }

模板:

public void createTemplate(String userName,long userId){
        log_.info("Inside create template ");
        long templateId=12504;
        DDMTemplate ddmTemplate=DDMTemplateLocalServiceUtil.createDDMTemplate(templateId);
        ddmTemplate.setName("MigrationTemplate");
        ddmTemplate.setDescription("This Template created programatically");
        ddmTemplate.setUserId(userId);
        ddmTemplate.setUserName(userName);

        try {
            BufferedReader br = new BufferedReader(new FileReader("D:/FilesDataMigration/template.txt"));
            StringBuilder sb = new StringBuilder();
            String line = br.readLine();

            while (line != null) {
                sb.append(line);
                sb.append(System.lineSeparator());
                line = br.readLine();
            }
            String script = sb.toString();
            ddmTemplate.setScript(script);
            DDMTemplateLocalServiceUtil.addDDMTemplate(ddmTemplate);
        }catch(IOException e){
            e.printStackTrace();
        } catch (SystemException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        log_.info("Inside create template done");
    }

以上代码段均正常运行，没有任何异常，但无法在控制面板"的内容部分中看到.如果有任何问题，建议我

The above snippets are executing properly with out any exceptions But unable to see in the content section of Control Panel.Suggest me if anything wrong

推荐答案

您的代码有几个问题:

1. 您没有设置所有必需的属性，例如groupId, companyId, classNameId, structureKey, dates等.

对于DDMStructure或DDMTemplate，没有任何setName和setDescription方法接受String自变量(Liferay 6.2 GA2).相反，只有setNameMap和setDescriptionMap方法都可以接受Map<Locale, String>.

There isn't any setName and setDescription method for DDMStructure or DDMTemplate accepting String argument (Liferay 6.2 GA2). Instead, there are only setNameMap and setDescriptionMap methods for both accepting Map<Locale, String>.

使用动态ID(structureId和templateId)代替硬编码ID，如下所示:DDMStructure ddmStructure = DDMStructureUtil.create(CounterLocalServiceUtil.increment());和DDMTemplate ddmTemplate = DDMTemplateUtil.create(CounterLocalServiceUtil.increment());

Use dynamic ids (structureId and templateId) in place of hard-coded ids, as following:DDMStructure ddmStructure = DDMStructureUtil.create(CounterLocalServiceUtil.increment());andDDMTemplate ddmTemplate = DDMTemplateUtil.create(CounterLocalServiceUtil.increment());

对于classNameId，您可以使用其值来获取它，例如:
ClassName className = ClassNameLocalServiceUtil.getClassName("com.liferay.portlet.journal.model.Journ‌​alArticle");long classNameId = className.getClassNameId();

For classNameId, you can get it using it's value, like:
ClassName className = ClassNameLocalServiceUtil.getClassName("com.liferay.portlet.journal.model.Journ‌​alArticle");long classNameId = className.getClassNameId();

此外，最好在填充的对象上使用update代替添加:DDMStructureUtil.update(ddmStructure);和DDMTemplateUtil.update(ddmTemplate);

Also, better to use update over populated object in place of adding:DDMStructureUtil.update(ddmStructure);andDDMTemplateUtil.update(ddmTemplate);

此外，如果您有权访问ThemeDisplay对象，则可以从中获取groupId, companyId, userId, userFullName.另外，为createDate和modifiedDate属性设置new Date().

Additionally, if you have access to the ThemeDisplay object, you can get groupId, companyId, userId, userFullName from it. Also, set new Date() for createDate and modifiedDate properties.
