.doc 的 Apache POI 3.13 离线/偏移元素

本文介绍了.doc 的 Apache POI 3.13 离线/偏移元素的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

所以基本上我需要在某些内容/元素段落或表格传递到另一个页面时验证生成的 .doc，如果某些元素/内容单独存在于另一个页面上，我需要获取另一个元素/内容并放入它与单独的元素/内容

public voidinvestigarDoc(XWPFDocument doc){尝试 {creacionDeFooter(doc);//页脚创建方法XWPFParagraphcuerpoObservaciones = doc.createParagraph();//第1段cuerpoObservaciones.setAlignment(ParagraphAlignment.DISTRIBUTE);XWPFRun imprimeObservaciones =cuerpoObservaciones.createRun();seccionObservaciones(doc,imprimeObservaciones,cuerpoObservaciones);//表创建方法XWPFParagraphcuerpoFirma = doc.createParagraph();//第2段cuerpoFirma.setAlignment(ParagraphAlignment.CENTER);XWPFRun imprimeFirma =cuerpoFirma.createRun();seccionFirma(doc,imprimeFirma,cuerpoFirma);//签名创建方法doc.write(new FileOutputStream("C:\\test.doc"));} catch (IOException iox) {iox.printStackTrace();System.out.println("错误:IOException Verificar Rutas de Archivos o Fotos！");}}

//页脚方法

public void creacionDeFooter(XWPFDocument doc){//FOOTER METHOD尝试 {CTP ctp = CTP.Factory.newInstance();//这个添加页码增量ctp.addNewR().addNewPgNum();XWPFParagraph parrafoFotter = 新 XWPFParagraph(ctp, doc);XWPFParagraph[] 段落 = 新 XWPFParagraph[1];段落[0] = parrafoFotter;//数字的位置parrafoFotter.setAlignment(ParagraphAlignment.RIGHT);CTSectPr sectPr = doc.getDocument().getBody().addNewSectPr();XWPFHeaderFooterPolicy headerFooterPolicy = new XWPFHeaderFooterPolicy(doc, sectPr);headerFooterPolicy.createFooter(STHdrFtr.DEFAULT, 段落);} catch (IOException e) {e.printStackTrace();}}

//第一款的方法

public void seccionObservaciones(XWPFDocument doc, XWPFRun otrasObservaciones,XWPFParagraph observaciones){//TABLE METHODotrasObservaciones = observaciones.createRun();otrasObservaciones.setText(".");otrasObservaciones.addBreak();//创建表XWPFTable 表 = doc.createTable();//创建第一行XWPFTableRow tableRowOne = table.getRow(0);tableRowOne.getCell(0).setText("Otras Operaciones/Observaciones");//创建第二行XWPFTableRow tableRowTwo = table.createRow();tableRowTwo.getCell(0).getTableRow();tableRowTwo.getCell(0).setText("colfore, rowfore");}

//第2段的方法

public void seccionFirma(XWPFDocument doc, XWPFRun imprimeFirma,XWPFParagraph Firma){//SIGNATURE METHODimprimeFirma = Firma.createRun();imprimeFirma.addBreak();imprimeFirma.setFontFamily("Arial");imprimeFirma.addBreak();imprimeFirma.setText("_________________________________________");imprimeFirma.addBreak();imprimeFirma.setText("NOMBRE PERSONA");imprimeFirma.addBreak();imprimeFirma.setText("PUESTO");imprimeFirma.addBreak();imprimeFirma.setText("GRUPO FINANCIERO BLABLA BLA");imprimeFirma.setText(".");}

这是最终结果的图片，这张图片一切正常:

但问题是如果发生这样的事情:

这是一个最常发生在验证中的例子

我尝试在页数的基础上处理这个问题，但似乎poi不存储页数.

如果表格和签名段落中的一些在新页面上，我需要将表格和签名段落移到另一页.

我将非常感激，非常感谢！问候.

解决方案

似乎您希望将行和段落放在一个页面上.这可以通过 Word 看到 https://support.office.com/en-us/article/Keep-text-together-af94e5b8-3a5a-4cb0-9c53-dea56b43d96d.

所以我们必须为每个段落设置属性KeepLines 和KeepNext.也适用于表内的人.

凹陷的线条是我的补充.

public void seccionObservaciones(XWPFDocument doc, XWPFRun otrasObservaciones, XWPFParagraph observaciones){//TABLE METHODotrasObservaciones = observaciones.createRun();otrasObservaciones.setText(".");otrasObservaciones.addBreak();//创建表XWPFTable 表 = doc.createTable();//创建第一行XWPFTableRow tableRowOne = table.getRow(0);tableRowOne.getCell(0).setText("Otras Operaciones/Observaciones");for (XWPFParagraph p : tableRowOne.getCell(0).getParagraphs()) {p.getCTP().addNewPPr().addNewKeepLines().setVal(STOnOff.ON);p.getCTP().getPPr().addNewKeepNext().setVal(STOnOff.ON);}//创建第二行XWPFTableRow tableRowTwo = table.createRow();tableRowTwo.getCell(0).getTableRow();tableRowTwo.getCell(0).setText("colfore, rowfore");对于 (XWPFParagraph p : tableRowTwo.getCell(0).getParagraphs()) {p.getCTP().addNewPPr().addNewKeepLines().setVal(STOnOff.ON);p.getCTP().getPPr().addNewKeepNext().setVal(STOnOff.ON);}}

//主要方法

...creacionDeFooter(doc);//页脚创建方法XWPFParagraphcuerpoObservaciones = doc.createParagraph();//第1段cuerpoObservaciones.setAlignment(ParagraphAlignment.DISTRIBUTE);cuerpoObservaciones.getCTP().getPPr().addNewKeepLines().setVal(STOnOff.ON);//已经通过setAlignment有一个CPPrcuerpoObservaciones.getCTP().getPPr().addNewKeepNext().setVal(STOnOff.ON);XWPFRun imprimeObservaciones =cuerpoObservaciones.createRun();seccionObservaciones(doc,imprimeObservaciones,cuerpoObservaciones);//表创建方法XWPFParagraphcuerpoFirma = doc.createParagraph();//第2段cuerpoFirma.getCTP().addNewPPr().addNewKeepLines().setVal(STOnOff.ON);cuerpoFirma.getCTP().getPPr().addNewKeepNext().setVal(STOnOff.ON);cuerpoFirma.setAlignment(ParagraphAlignment.CENTER);XWPFRun imprimeFirma =cuerpoFirma.createRun();seccionFirma(doc,imprimeFirma,cuerpoFirma);//签名创建方法doc.write(new FileOutputStream("test.docx"));...

org.openxmlformats.schemas.wordprocessingml.x2006.main.STOnOff 需要 STOnOff.ON.但是您已经在使用其他 org.openxmlformats.schemas.wordprocessingml.x2006.main. 对象.所以你会知道如何获得这个.

编辑

忘记说了.请不要将 XWPFDocument 保存为 *.doc 文件.*.doc文件主要用于Word到2003版本的二进制文件格式.XWPFDocument是XML> 基于并应保存为 *.docx.

So basically I have a requirement to validate a generated .doc when some content/ element Paragraph or Table pass to another page, and if some element/content it's alone on the other page I need to take another element/content and put it with the alone element/content

public void investigarDoc(XWPFDocument doc){
    try {

        creacionDeFooter(doc);//FOOTER CREATION METHOD

        XWPFParagraph cuerpoObservaciones = doc.createParagraph(); //PARAGRAPH 1
        cuerpoObservaciones.setAlignment(ParagraphAlignment.DISTRIBUTE);
        XWPFRun imprimeObservaciones = cuerpoObservaciones.createRun();
        seccionObservaciones(doc,imprimeObservaciones,cuerpoObservaciones); //TABLE CREATION METHOD

        XWPFParagraph cuerpoFirma = doc.createParagraph();  //PARAGRAPH 2
        cuerpoFirma.setAlignment(ParagraphAlignment.CENTER);
        XWPFRun imprimeFirma = cuerpoFirma.createRun();
        seccionFirma(doc,imprimeFirma,cuerpoFirma); //SIGNATURE CREATION METHOD

        doc.write(new FileOutputStream("C:\\test.doc"));

    } catch (IOException iox) {
        iox.printStackTrace();
        System.out.println("Error: IOException Verificar Rutas de Archivos o Fotos!");
    }
}

//Footer Method

public void creacionDeFooter(XWPFDocument doc){ //FOOTER METHOD
    try {
        CTP ctp = CTP.Factory.newInstance();
        //this add page number incremental
        ctp.addNewR().addNewPgNum();

        XWPFParagraph parrafoFotter = new XWPFParagraph(ctp, doc);
        XWPFParagraph[] paragraphs = new XWPFParagraph[1];
        paragraphs[0] = parrafoFotter;

        //position of number
        parrafoFotter.setAlignment(ParagraphAlignment.RIGHT);

        CTSectPr sectPr = doc.getDocument().getBody().addNewSectPr();

        XWPFHeaderFooterPolicy headerFooterPolicy = new XWPFHeaderFooterPolicy(doc, sectPr);
        headerFooterPolicy.createFooter(STHdrFtr.DEFAULT, paragraphs);

        } catch (IOException e) {
            e.printStackTrace();
        }
}

//Method of Paragraph 1

public void seccionObservaciones(XWPFDocument doc, XWPFRun otrasObservaciones,XWPFParagraph observaciones){ //TABLE METHOD

    otrasObservaciones = observaciones.createRun();
    otrasObservaciones.setText(".");
    otrasObservaciones.addBreak();
     //create table
    XWPFTable table = doc.createTable();
    //create first row
    XWPFTableRow tableRowOne = table.getRow(0);
    tableRowOne.getCell(0).setText("Otras Operaciones/Observaciones");

    //create second row
    XWPFTableRow tableRowTwo = table.createRow();
    tableRowTwo.getCell(0).getTableRow();
    tableRowTwo.getCell(0).setText("col fore, row fore");

 }

//Method of Paragraph 2

public void seccionFirma(XWPFDocument doc, XWPFRun imprimeFirma,XWPFParagraph firma){ //SIGNATURE METHOD
    imprimeFirma = firma.createRun();
    imprimeFirma.addBreak();
    imprimeFirma.setFontFamily("Arial");
    imprimeFirma.addBreak();
    imprimeFirma.setText("_________________________________________");
    imprimeFirma.addBreak();
    imprimeFirma.setText("NOMBRE PERSONA");
    imprimeFirma.addBreak();
    imprimeFirma.setText("PUESTO");
    imprimeFirma.addBreak();
    imprimeFirma.setText("GRUPO FINANCIERO BLABLA BLA");
    imprimeFirma.setText(".");

}

Here is a pic of the final result, all fine with this pic:

But the problem is if something like this happen:

This is an example that most happen with the validation

I try in base of the number page to handle this problem, but it seems that poi does not store the page num.

I need than the table and the signature paragraph come to the other page if some of the 2 it's on an new page.

I will be really grateful, many thanks! Regards.

解决方案

Seems as if you want keep together the lines and paragraphs on one page. This is possible with Word see https://support.office.com/en-us/article/Keep-text-together-af94e5b8-3a5a-4cb0-9c53-dea56b43d96d.

So we must set the properties KeepLines and KeepNext for each paragraph. Also for those within the table.

The out-dented lines are my additions.

public void seccionObservaciones(XWPFDocument doc, XWPFRun otrasObservaciones, XWPFParagraph observaciones){ //TABLE METHOD

    otrasObservaciones = observaciones.createRun();
    otrasObservaciones.setText(".");
    otrasObservaciones.addBreak();
     //create table
    XWPFTable table = doc.createTable();
    //create first row
    XWPFTableRow tableRowOne = table.getRow(0);
    tableRowOne.getCell(0).setText("Otras Operaciones/Observaciones");

for (XWPFParagraph p : tableRowOne.getCell(0).getParagraphs()) {
 p.getCTP().addNewPPr().addNewKeepLines().setVal(STOnOff.ON);
 p.getCTP().getPPr().addNewKeepNext().setVal(STOnOff.ON);
}

    //create second row
    XWPFTableRow tableRowTwo = table.createRow();
    tableRowTwo.getCell(0).getTableRow();
    tableRowTwo.getCell(0).setText("col fore, row fore");

for (XWPFParagraph p : tableRowTwo.getCell(0).getParagraphs()) {
 p.getCTP().addNewPPr().addNewKeepLines().setVal(STOnOff.ON);
 p.getCTP().getPPr().addNewKeepNext().setVal(STOnOff.ON);
}

 }

//main method

...
        creacionDeFooter(doc);//FOOTER CREATION METHOD

        XWPFParagraph cuerpoObservaciones = doc.createParagraph(); //PARAGRAPH 1
        cuerpoObservaciones.setAlignment(ParagraphAlignment.DISTRIBUTE);

cuerpoObservaciones.getCTP().getPPr().addNewKeepLines().setVal(STOnOff.ON); //has already a CPPr through setAlignment
cuerpoObservaciones.getCTP().getPPr().addNewKeepNext().setVal(STOnOff.ON);

        XWPFRun imprimeObservaciones = cuerpoObservaciones.createRun();
        seccionObservaciones(doc,imprimeObservaciones,cuerpoObservaciones); //TABLE CREATION METHOD

        XWPFParagraph cuerpoFirma = doc.createParagraph();  //PARAGRAPH 2

cuerpoFirma.getCTP().addNewPPr().addNewKeepLines().setVal(STOnOff.ON);
cuerpoFirma.getCTP().getPPr().addNewKeepNext().setVal(STOnOff.ON);

        cuerpoFirma.setAlignment(ParagraphAlignment.CENTER);
        XWPFRun imprimeFirma = cuerpoFirma.createRun();
        seccionFirma(doc,imprimeFirma,cuerpoFirma); //SIGNATURE CREATION METHOD

        doc.write(new FileOutputStream("test.docx"));
...

org.openxmlformats.schemas.wordprocessingml.x2006.main.STOnOff is needed for STOnOff.ON. But you using other org.openxmlformats.schemas.wordprocessingml.x2006.main. objects already. So you will know how to get this.

Edit

Forgot to mention. Please do not save XWPFDocument as *.doc file. A *.doc file is mainly used for the binary file format of Word up to version 2003. XWPFDocument is XML based and should be saved as *.docx.
