XPages -使用POI4 XPages poiBean

Question

我正在尝试使用POI (来自POI4 XPages)来生成包含来自XPage的内容的Word文档。我已经按照POI示例数据库中的示例添加并配置了REST服务。

var template = poiBean.buildResourceTemplateSource(null,"YourFile.docx");
var lstBM = new java.util.ArrayList();
var jce:CategoryFields = new CategoryFields();
var doc = currentDocument.getDocument(true);
var retOutput1 = jce.getCategoryField1(doc);
var retOutput2 = jce.getCategoryField2(doc);
var doc:NotesDocument = currentDocument.getDocument();
var Field1 = retOutput1;
var Field2 = retOutput2;
lstBM.add(poiBean.buildDocumentBookmark("Field1", retOutput1));
lstBM.add(poiBean.buildDocumentBookmark("Field2", retOutput2));
var result = poiBean.processDocument2Stream(template, lstBM);
if (result == null) {
print("?????");
}
return new java.io.ByteArrayInputStream(result.toByteArray()) 

我现在想创建一个响应文档，它在富文本字段中包含上述代码的结果。我更喜欢在按钮的onClick事件中放置必要的代码(我想是SSJS)。但是，通过按钮我不知道如何处理REST服务的输出。有人知道我是怎么做到的吗？

我已经修改了下面建议的代码如下：

package AZGPackage;
import java.io.*;
import java.util.List;
import lotus.domino.*;
import biz.webgate.dominoext.poi.beans.PoiBean;
import biz.webgate.dominoext.poi.component.data.ITemplateSource;

public class MimeMaker {

private final PoiBean poiBean;
private final String templateName;
private String resultName;

public MimeMaker(PoiBean poiBean, String templateName, String resultName) {
    this.poiBean = poiBean;
    this.templateName = templateName;
}

public void renderToDocument(Session s, Document doc) throws NotesException {

    ITemplateSource template = poiBean.buildResourceTemplateSource(null,this.templateName);
    List lstBM = new java.util.ArrayList();
    CategoryFields jce = new CategoryFields();
    String retOutput1 = jce.getCategoryField1(doc);
    String retOutput2 = jce.getCategoryField2(doc);

    lstBM.add(poiBean.buildDocumentBookmark("Fachkompetenz", retOutput1));
    lstBM.add(poiBean.buildDocumentBookmark("Arbeitsverhalten", retOutput2));
    ByteArrayOutputStream result = poiBean.processDocument2Stream(template, lstBM);

    // Do the mime
    s.setConvertMime(false);
    MIMEEntity emailRoot = doc.createMIMEEntity("Body");
    MIMEEntity emailRootChild = emailRoot.createChildEntity();

    MIMEHeader emailHeader = emailRootChild.createHeader("Content-Disposition");
    emailHeader.setHeaderVal("attachment; filename=\"" + resultName + "\"");
    InputStream is = new ByteArrayInputStream(result.toByteArray());
    Stream stream = s.createStream();
    stream.setContents(is);
    emailRootChild.setContentFromBytes(stream, "x-vnd/ms-office-docx", MIMEEntity.ENC_IDENTITY_BINARY);

    s.setConvertMime(true);

   }
 }

但是，在调用之后：

var mimeMaker = new AZGPackage.MimeMaker(poiBean, "YourFile.docx", "someFile.docx");
mimeMaker.renderToDocument(session, currentDocument.getDocument(true));

我得到了错误：

脚本解释器错误，line=3，col=11:在java类'AZGPackage.MimeMaker‘上调用方法'renderToDocument(lotus.domino.local.Session，lotus.domino.local.Document)’时出错

创建一个Java类，大致如下：

public class MimeMaker {

private final PoiBean poiBean;
private final String templateName;

public MimeMaker(PoiBean poiBean, String templateName, String resultName) {
    this.poiBean = poiBean;
    this.templateName = templateName;
}

public void renderToDocument(Session s, Document doc) {
    Template template = poiBean.buildResourceTemplateSource(null,this.templateName);
    Collection lstBM = new java.util.ArrayList();
    CategoryFields jce = new CategoryFields();
    String retOutput1 = jce.getCategoryField1(doc);
    String retOutput2 = jce.getCategoryField2(doc);

    lstBM.add(poiBean.buildDocumentBookmark("Field1", retOutput1));
    lstBM.add(poiBean.buildDocumentBookmark("Field2", retOutput2));
    ByteArrayOutputStream result = poiBean.processDocument2Stream(template, lstBM);

    // Do the mime
    s.setConvertMime(false);
    MIMEEntity emailRoot = emailDocument.createMIMEEntity("Body");
    MIMEEntity emailRootChild = emailRoot.createChildEntity();

    MIMEHeader emailHeader = emailRootChild.createHeader("Content-Disposition");
    emailHeader.setHeaderVal("attachment; filename=\"" + resultName + "\"");
    InputStream is = new ByteArrayInputStream(result.toByteArray());
    Stream stream = s.createStream();
    stream.setContents(is);
    emailRootChild.setContentFromBytes(stream, "x-vnd/ms-office-docx", MIMEEntity.ENC_IDENTITY_BINARY);

    s.setConvertMime(true);
   }
 }

您需要修复数据类型(我刚刚在记事本中键入)，但您得到了要点。然后，您可以进入按钮并执行以下操作：

    var mimeMaker = new com.acme.MimeMaker(poiBean, "YourFile.docx", "someFile.docx");
    mimeMaker.renderToDocument(session, currentDocument.getDocument(true);

让我们知道进展如何

我使用docx4j库解决了这个问题。我认为这是一个比Apache POI更好的选择。查看http://www.docx4java.org
