Java使用poi-tl库操作wold文档的方法

作者：布Coder

java项目实际开发中经常会遇到制作word表单且表格数据行循环功能,这篇文章主要介绍了Java使用poi-tl库操作wold文档的相关资料,文中通过代码介绍的非常详细,需要的朋友可以参考下

poi-tl 是一个基于Apache POI的Word模板引擎，也是一个免费开源的Java类库，

适用范围:

在线文档生成、合同签订、信息替换方面具有很大优势、采用 标签-替换的实现策略,简单易上手、避免实际业务中的重复开发. 业务与设计解藕.

开始操作

引入 poi-tl 项目

        <poi-version>5.4.0</poi-version>
        
        -- poi 项目依赖

        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi</artifactId>
            <version>${poi-version}</version>
        </dependency>

        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml</artifactId>
            <version>${poi-version}</version>
        </dependency>

        -- poi-tl 项目依赖
        <dependency>
            <groupId>com.deepoove</groupId>
            <artifactId>poi-tl</artifactId>
            <version>1.12.2</version>
        </dependency>

本讲介绍模版生成(poi - tl支持无模版生成)

读取模版文件、并且定义结果输出

        XWPFTemplate
                .compile("模版文档.docx")
                .render(map)
                .writeAndClose(new FileOutputStream("01.docx"));

普通图文本替换 (文档内容 {{key}})

模版文件

代码

        HashMap<String, Object> renderMap = new HashMap<>();

        renderMap.put("text","我是被替换的内容");

        XWPFTemplate
                .compile("空白文档.docx")
                .render(renderMap).
                writeAndClose(new FileOutputStream("01.docx"));

输出文件

列表内容生成 {{#key}}

模版

代码实现

        HashMap<String, Object> renderMap = new HashMap<>();

        renderMap.put("text", "我是被替换的内容");

        HashMap<String, Object> ones = new HashMap<>();

        ones.put("name", "981129-1");
        ones.put("date", new Date());

        ArrayList<Object> list = new ArrayList<>();
        list.add(ones);
        list.add(ones);
        list.add(ones);
        list.add(ones);

        renderMap.put("list", list);

        // 表格循环插件
        LoopRowTableRenderPolicy rowTableRenderPolicy = new LoopRowTableRenderPolicy();
        Configure configure = Configure.builder()
                .bind("list", rowTableRenderPolicy)
                .build();


        XWPFTemplate
                .compile("空白文档.docx", configure)
                .render(renderMap).
                writeAndClose(new FileOutputStream("01.docx"));

复杂结构列表内容生成 (循环生成普通文本 + 列表)

自定义实现(代码)
