引言

在现代办公自动化和文档处理领域，microsoft word的.docx格式已成为行业标准。对于需要在java应用程序中生成、修改或处理word文档的开发者来说，docx4j是一个强大而专业的选择。本文将全面介绍docx4j库的特点、使用方法和适用场景，并通过丰富的代码示例展示其强大功能。

一、环境准备与基础配置

1.1 maven依赖配置

<dependency>
    <groupid>org.docx4j</groupid>
    <artifactid>docx4j-core</artifactid>
    <version>8.3.4</version>
</dependency>
<dependency>
    <groupid>org.docx4j</groupid>
    <artifactid>docx4j-export-fo</artifactid>
    <version>8.3.4</version>
</dependency>

1.2 初始化测试类

public class docx4jtest {
    private wordprocessingmlpackage wordpackage;
    private objectfactory factory;
    
    @beforeeach
    public void setup() throws exception {
        wordpackage = wordprocessingmlpackage.createpackage();
        factory = context.getwmlobjectfactory();
    }
    
    @aftereach
    public void teardown() throws exception {
        if (wordpackage != null) {
            wordpackage.save(new file("test_output.docx"));
        }
    }
}

二、增强版文档操作示例

2.1 复杂表格生成（带样式和合并单元格）

@test
public void testcreatecomplextable() throws exception {
    // 创建5x5表格
    tbl table = factory.createtbl();
    
    // 设置表格属性
    tblpr tblpr = factory.createtblpr();
    tblwidth tblwidth = factory.createtblwidth();
    tblwidth.setw(biginteger.valueof(5000));
    tblwidth.settype("dxa");
    tblpr.settblwidth(tblwidth);
    table.settblpr(tblpr);
    
    // 创建表头行
    tr headerrow = factory.createtr();
    for (int i = 0; i < 5; i++) {
        tc cell = createtablecell("表头 " + (i+1), true, "ff0000");
        headerrow.getcontent().add(cell);
    }
    table.getcontent().add(headerrow);
    
    // 创建数据行（带合并单元格）
    for (int row = 0; row < 4; row++) {
        tr datarow = factory.createtr();
        for (int col = 0; col < 5; col++) {
            if (row == 1 && col == 1) {
                // 合并单元格（横向合并2个）
                tc cell = createtablecell("合并单元格", false, "00ff00");
                cell.gettcpr().setgridspan(new biginteger("2"));
                datarow.getcontent().add(cell);
                col++; // 跳过下一个单元格
            } else if (row == 2 && col == 0) {
                // 合并单元格（纵向合并2个）
                tc cell = createtablecell("纵向合并", false, "0000ff");
                cell.gettcpr().setvmerge(factory.createctvmerge());
                cell.gettcpr().getvmerge().setval("restart");
                datarow.getcontent().add(cell);
            } else if (row == 3 && col == 0) {
                // 继续纵向合并
                tc cell = createtablecell("", false, "0000ff");
                cell.gettcpr().setvmerge(factory.createctvmerge());
                cell.gettcpr().getvmerge().setval("continue");
                datarow.getcontent().add(cell);
            } else {
                datarow.getcontent().add(
                    createtablecell("数据 "+row+","+col, false, null));
            }
        }
        table.getcontent().add(datarow);
    }
    
    wordpackage.getmaindocumentpart().addobject(table);
    
    assertnotnull(table);
    assertequals(5, table.getcontent().size());
}

2.2 文档样式管理

@test
public void testdocumentstyles() throws exception {
    // 创建样式定义
    styles styles = factory.createstyles();
    
    // 标题1样式
    style titlestyle = factory.createstyle();
    titlestyle.settype("paragraph");
    titlestyle.setstyleid("heading1");
    style.name name = factory.createstylename();
    name.setval("标题 1");
    titlestyle.setname(name);
    
    ppr ppr = factory.createppr();
    ppr.setoutlinelvl(new biginteger("0"));
    jc jc = factory.createjc();
    jc.setval(jcenumeration.center);
    ppr.setjc(jc);
    titlestyle.setppr(ppr);
    
    rpr rpr = factory.createrpr();
    rpr.setb(new booleandefaulttrue());
    rpr.setsz(new hpsmeasure(biginteger.valueof(32)));
    rpr.setcolor(new color("2f5496"));
    titlestyle.setrpr(rpr);
    
    styles.getstyle().add(titlestyle);
    
    // 将样式添加到文档
    wordpackage.getmaindocumentpart().setstyledefinitionspart(
        new stylespart(wordpackage, styles));
    
    // 使用样式
    p p = factory.createp();
    ppr ppr = factory.createppr();
    ppr.setpstyle("heading1");
    p.setppr(ppr);
    r r = factory.creater();
    text t = factory.createtext();
    t.setvalue("这是标题1样式");
    r.getcontent().add(t);
    p.getcontent().add(r);
    wordpackage.getmaindocumentpart().addobject(p);
    
    // 验证样式是否存在
    assertnotnull(wordpackage.getmaindocumentpart().getstyledefinitionspart());
    assertequals(1, wordpackage.getmaindocumentpart()
        .getstyledefinitionspart().getjaxbelement().getstyle().size());
}

三、高级功能实现

3.1 生成带目录的文档

@test
public void testgeneratetoc() throws exception {
    // 添加标题样式（同2.2节）
    // ...
    
    // 添加几个带样式的标题
    addstyledparagraph("heading1", "第一章 简介");
    addstyledparagraph("heading2", "1.1 背景");
    addstyledparagraph("heading1", "第二章 实现");
    addstyledparagraph("heading2", "2.1 技术选型");
    
    // 创建目录字段代码
    p tocparagraph = factory.createp();
    fldchar fldchar = factory.createfldchar();
    fldchar.setfldchartype(stfldchartype.begin);
    tocparagraph.getcontent().add(fldchar);
    
    r tocrun = factory.creater();
    text toctext = factory.createtext();
    toctext.setspace("preserve");
    toctext.setvalue(" toc \\o \"1-3\" \\h \\z \\u ");
    tocrun.getcontent().add(toctext);
    tocparagraph.getcontent().add(tocrun);
    
    fldchar fldcharsep = factory.createfldchar();
    fldcharsep.setfldchartype(stfldchartype.separate);
    tocparagraph.getcontent().add(fldcharsep);
    
    // 目录占位文本
    r placeholderrun = factory.creater();
    text placeholdertext = factory.createtext();
    placeholdertext.setvalue("目录将在此生成...");
    placeholderrun.getcontent().add(placeholdertext);
    tocparagraph.getcontent().add(placeholderrun);
    
    fldchar fldcharend = factory.createfldchar();
    fldcharend.setfldchartype(stfldchartype.end);
    tocparagraph.getcontent().add(fldcharend);
    
    // 将目录添加到文档开头
    wordpackage.getmaindocumentpart().addobject(0, tocparagraph);
    
    // 更新字段（生成实际目录）
    fieldupdater updater = new fieldupdater(wordpackage);
    updater.update(true);
    
    // 验证目录是否存在
    asserttrue(wordpackage.getmaindocumentpart().getcontent().get(0) instanceof p);
}

3.2 文档加密与保护

@test
public void testdocumentprotection() throws exception {
    // 设置文档保护
    documentprotection protection = new documentprotection();
    protection.setedit(protectionedittype.read_only);
    protection.setpassword("123456");
    
    // 应用保护设置
    wordpackage.getmaindocumentpart().getcontents().getbody().setdocumentprotection(
        protection.createdocumentprotection());
    
    // 添加一些内容
    wordpackage.getmaindocumentpart().addparagraphoftext("这是受保护的文档");
    
    // 保存并重新加载验证保护
    bytearrayoutputstream baos = new bytearrayoutputstream();
    wordpackage.save(baos);
    
    bytearrayinputstream bais = new bytearrayinputstream(baos.tobytearray());
    wordprocessingmlpackage protectedpackage = wordprocessingmlpackage.load(bais);
    
    // 尝试修改（应抛出异常）
    assertthrows(docx4jexception.class, () -> {
        protectedpackage.getmaindocumentpart().addparagraphoftext("尝试修改");
        protectedpackage.save(new file("protected.docx"));
    });
    
    // 使用密码解除保护
    protectedpackage = wordprocessingmlpackage.load(new bytearrayinputstream(baos.tobytearray()));
    protectedpackage.getmaindocumentpart().removeprotection("123456");
    protectedpackage.getmaindocumentpart().addparagraphoftext("已解除保护");
    protectedpackage.save(new file("unprotected.docx"));
}

四、测试工具类与实用方法

4.1 文档比较工具类

public class docxcomparator {
    public static boolean comparedocs(file doc1, file doc2) throws exception {
        wordprocessingmlpackage pkg1 = wordprocessingmlpackage.load(doc1);
        wordprocessingmlpackage pkg2 = wordprocessingmlpackage.load(doc2);
        
        // 比较文档结构
        if (!compareparts(pkg1.getmaindocumentpart(), pkg2.getmaindocumentpart())) {
            return false;
        }
        
        // 比较样式
        if (!comparestyles(pkg1, pkg2)) {
            return false;
        }
        
        return true;
    }
    
    private static boolean compareparts(part part1, part part2) {
        // 实现具体的比较逻辑
        // ...
        return true;
    }
    
    private static boolean comparestyles(wordprocessingmlpackage pkg1, 
                                       wordprocessingmlpackage pkg2) {
        // 实现样式比较逻辑
        // ...
        return true;
    }
}

// 测试用例
@test
public void testdocumentcomparison() throws exception {
    file original = new file("template.docx");
    file generated = new file("test_output.docx");
    
    // 生成测试文档
    wordprocessingmlpackage pkg = wordprocessingmlpackage.createpackage();
    pkg.getmaindocumentpart().addparagraphoftext("测试内容");
    pkg.save(generated);
    
    // 比较文档
    assertfalse(docxcomparator.comparedocs(original, generated));
    
    // 比较相同文档
    asserttrue(docxcomparator.comparedocs(generated, generated));
}

4.2 性能测试工具

public class docx4jbenchmark {
    public static long measuredocumentcreation(int paragraphcount) throws exception {
        long start = system.currenttimemillis();
        
        wordprocessingmlpackage wordpackage = wordprocessingmlpackage.createpackage();
        objectfactory factory = context.getwmlobjectfactory();
        
        for (int i = 0; i < paragraphcount; i++) {
            p p = factory.createp();
            r r = factory.creater();
            text t = factory.createtext();
            t.setvalue("段落 " + (i+1));
            r.getcontent().add(t);
            p.getcontent().add(r);
            wordpackage.getmaindocumentpart().addobject(p);
        }
        
        bytearrayoutputstream out = new bytearrayoutputstream();
        wordpackage.save(out);
        
        return system.currenttimemillis() - start;
    }
}

// 性能测试用例
@test
public void testperformance() throws exception {
    int[] testsizes = {100, 1000, 5000};
    
    for (int size : testsizes) {
        long time = docx4jbenchmark.measuredocumentcreation(size);
        system.out.printf("生成 %d 段落的文档耗时: %d ms%n", size, time);
        asserttrue(time < 10000, "性能测试失败，耗时过长");
    }
}

五、集成测试示例

5.1 端到端文档生成测试

@test
public void testendtoenddocumentgeneration() throws exception {
    // 1. 创建文档
    wordprocessingmlpackage wordpackage = wordprocessingmlpackage.createpackage();
    
    // 2. 添加封面
    addcoverpage(wordpackage);
    
    // 3. 添加目录
    addtableofcontents(wordpackage);
    
    // 4. 添加章节内容
    addchapter(wordpackage, "1. 简介", "这是文档的简介部分...");
    addchapter(wordpackage, "2. 实现", "详细实现说明...");
    
    // 5. 添加表格
    addsampletable(wordpackage);
    
    // 6. 添加图表
    addsamplechart(wordpackage);
    
    // 7. 添加页眉页脚
    addheaderfooter(wordpackage);
    
    // 8. 保存文档
    file output = new file("full_document.docx");
    wordpackage.save(output);
    
    // 验证
    asserttrue(output.exists());
    asserttrue(output.length() > 1024); // 文档大小应大于1kb
    
    // 验证文档结构
    wordprocessingmlpackage loaded = wordprocessingmlpackage.load(output);
    assertnotnull(loaded.getmaindocumentpart());
    assertnotnull(loaded.getmaindocumentpart().getstyledefinitionspart());
    
    // 验证内容
    string xml = xmlutils.marshaltostring(
        loaded.getmaindocumentpart().getjaxbelement(), true);
    asserttrue(xml.contains("简介"));
    asserttrue(xml.contains("实现"));
}

5.2 异常处理测试

@test
public void testexceptionhandling() {
    // 测试无效文件加载
    assertthrows(docx4jexception.class, () -> {
        wordprocessingmlpackage.load(new file("nonexistent.docx"));
    });
    
    // 测试无效操作
    assertthrows(illegalstateexception.class, () -> {
        wordprocessingmlpackage wordpackage = wordprocessingmlpackage.createpackage();
        wordpackage.save(null);
    });
    
    // 测试样式操作错误
    assertthrows(invalidformatexception.class, () -> {
        wordprocessingmlpackage wordpackage = wordprocessingmlpackage.createpackage();
        p p = factory.createp();
        ppr ppr = factory.createppr();
        ppr.setpstyle("invalidstyle");
        p.setppr(ppr);
        wordpackage.getmaindocumentpart().addobject(p);
        wordpackage.save(new file("invalid_style.docx"));
    });
}

六、实用工具方法集

文档生成工具类

public class docxgenerator {
    private final wordprocessingmlpackage wordpackage;
    private final objectfactory factory;
    
    public docxgenerator() throws docx4jexception {
        this.wordpackage = wordprocessingmlpackage.createpackage();
        this.factory = context.getwmlobjectfactory();
    }
    
    public void addtitle(string text, int level) {
        p p = factory.createp();
        ppr ppr = factory.createppr();
        ppr.setpstyle("heading" + level);
        p.setppr(ppr);
        
        r r = factory.creater();
        text t = factory.createtext();
        t.setvalue(text);
        r.getcontent().add(t);
        p.getcontent().add(r);
        
        wordpackage.getmaindocumentpart().addobject(p);
    }
    
    public void addparagraph(string text) {
        wordpackage.getmaindocumentpart().addparagraphoftext(text);
    }
    
    public void addtable(list<list<string>> data) {
        tbl table = factory.createtbl();
        
        // 添加表头
        if (!data.isempty()) {
            tr headerrow = factory.createtr();
            for (string header : data.get(0)) {
                headerrow.getcontent().add(createtablecell(header, true, null));
            }
            table.getcontent().add(headerrow);
        }
        
        // 添加数据行
        for (int i = 1; i < data.size(); i++) {
            tr datarow = factory.createtr();
            for (string celldata : data.get(i)) {
                datarow.getcontent().add(createtablecell(celldata, false, null));
            }
            table.getcontent().add(datarow);
        }
        
        wordpackage.getmaindocumentpart().addobject(table);
    }
    
    public void savetofile(string filename) throws docx4jexception {
        wordpackage.save(new file(filename));
    }
    
    private tc createtablecell(string text, boolean isheader, string color) {
        tc cell = factory.createtc();
        p p = factory.createp();
        r r = factory.creater();
        text t = factory.createtext();
        t.setvalue(text);
        r.getcontent().add(t);
        
        if (isheader || color != null) {
            rpr rpr = factory.createrpr();
            if (isheader) {
                rpr.setb(new booleandefaulttrue());
            }
            if (color != null) {
                color textcolor = new color();
                textcolor.setval(color);
                rpr.setcolor(textcolor);
            }
            r.setrpr(rpr);
        }
        
        p.getcontent().add(r);
        cell.getcontent().add(p);
        return cell;
    }
}

// 使用示例
@test
public void testdocxgenerator() throws exception {
    docxgenerator generator = new docxgenerator();
    
    generator.addtitle("测试文档", 1);
    generator.addparagraph("这是一个自动生成的测试文档");
    
    list<list<string>> tabledata = new arraylist<>();
    tabledata.add(arrays.aslist("id", "名称", "数量"));
    tabledata.add(arrays.aslist("1", "商品a", "100"));
    tabledata.add(arrays.aslist("2", "商品b", "200"));
    generator.addtable(tabledata);
    
    generator.savetofile("generated_doc.docx");
    
    file output = new file("generated_doc.docx");
    asserttrue(output.exists());
}
