Java 从liferay portlet下载xml文件的压缩文件夹

我有一个portlet，我想使用SpringMVC下载一些动态创建的文件。我的意思是我有一个字符串列表

List<String> xmls

我不知道我该怎么做。我发现，如何下载一个，简单的文件，但没有解决方案，如何下载压缩文件夹中的文件，从字符串列表中动态创建

假设Liferay 6.1

进口

import java.io.File;
import com.liferay.portal.kernel.util.FileUtil;
import com.liferay.portal.kernel.zip.ZipWriter;
import com.liferay.portal.kernel.zip.ZipWriterFactoryUtil;

您的资源方法应该如下所示

    response.setProperty("Content-Disposition", "attachment; filename=myarchive.zip");
    response.setContentType("application/zip");

    final ZipWriter writer = ZipWriterFactoryUtil.getZipWriter();

    for (String filename : xmls) {
        byte[] file = FileUtil.getBytes(new File("filename"));
        writer.addEntry(filename, file);
    }

    byte[] archive = writer.finish();
    response.getPortletOutputStream().write(archive);

@ResourceMapping("exportForms")
public void exportForms(ResourceRequest request, ResourceResponse response) {...}

import java.io.File;
import com.liferay.portal.kernel.util.FileUtil;
import com.liferay.portal.kernel.zip.ZipWriter;
import com.liferay.portal.kernel.zip.ZipWriterFactoryUtil;

    response.setProperty("Content-Disposition", "attachment; filename=myarchive.zip");
    response.setContentType("application/zip");

    final ZipWriter writer = ZipWriterFactoryUtil.getZipWriter();

    for (String filename : xmls) {
        byte[] file = FileUtil.getBytes(new File("filename"));
        writer.addEntry(filename, file);
    }

    byte[] archive = writer.finish();
    response.getPortletOutputStream().write(archive);
