SpringBoot将数据写入word模板，生成word文档

用途：生成电子履历或者固定格式文档

依赖：

        <dependency>
            <groupId>org.freemarker</groupId>
            <artifactId>freemarker</artifactId>
            <version>2.3.30</version>
        </dependency>

代码：

import freemarker.template.Configuration;
import freemarker.template.Template;
import org.springframework.core.io.ByteArrayResource;
import org.springframework.core.io.InputStreamSource;

import java.io.*;
import java.nio.charset.StandardCharsets;
import java.util.Map;

/**
 * @program: world
 * @description: doc工具类
 * @author: XinHai.Ma
 * @create: 2021-09-09 15:54
 */
public class DocUtils {

    public static void saveWord(String filePath, Map<String,Object> dataMap) throws IOException {
        Configuration configuration = new Configuration();
        configuration.setDefaultEncoding("utf-8");
        configuration.setClassForTemplateLoading(DocUtils.class, "/");
        Template template = configuration.getTemplate("templates/template.xml");
        InputStreamSource streamSource = createWord(template, dataMap);
        InputStream inputStream = streamSource.getInputStream();
        FileOutputStream outputStream = new FileOutputStream(filePath);
        byte[] bytes = new byte[1024];
        while ((inputStream.read(bytes)) != -1) {
            outputStream.write(bytes);// 写入数据
        }
        inputStream.close();
        outputStream.close();
    }

    public static InputStreamSource createWord(Template template, Map<String, Object> dataMap) {
        StringWriter out = null;
        Writer writer = null;
        try {
            out = new StringWriter();
            writer = new BufferedWriter(out, 1024);
            template.process(dataMap, writer);
            return new ByteArrayResource(out.toString().getBytes(StandardCharsets.UTF_8));
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                writer.close();
                out.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return null;
    }

}

调用代码：

import com.maxinhai.world.utils.DocUtils;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

/**
 * @program: world
 * @description: doc测试用例
 * @author: XinHai.Ma
 * @create: 2021-09-09 16:16
 */
@RunWith(SpringRunner.class)
@SpringBootTest
public class DocTests {

    @Test
    public void test() {
        try {
            Map<String, Object> dataMap = new HashMap<>();
            dataMap.put("title", "献祭之主");
            dataMap.put("author", "王信");
            dataMap.put("createDate", "2021年9月9日");
            dataMap.put("title_item1", "第14章 :我父母为了保护北马城所牺牲!");
            dataMap.put("content", "我父母为了保护北马市，死在了魔兽攻城中！");
            DocUtils.saveWord("C:\Users\86186\Documents\献祭之主.docx", dataMap);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

模板制作：

1. 新建一个word文档，填入固定内容；

2. 在要用程序写入数据的地方，插入-文档部件-域-自动图文集列(微软Word叫AUTOTEXTLIST)，标签名和程序标签要对应；

3. 文档保存为Word XML格式；

4. 放入程序要去读取模板的路径；

生成文档效果：
