1. 处理Word模板 1.1 定义word模版 1.2 定义完我们的模板之后，我们要将文档保存为xml的格式定义完我们的模板之后，我们要将文档保存为xml的格式 1.3 xml格式化

1. 处理Word模板

1.1 定义word模版

word模版

1.2 定义完我们的模板之后，我们要将文档保存为xml的格式

定义完我们的模板之后，我们要将文档保存为xml的格式

在这里插入图片描述

1.3 xml格式化

生成的xml格式看起来比较乱,没有层次感, 所以需要格式化一下

格式化

格式化xml

1.4 修改xml

基础信息的定义

基础信息的定义只要保证我们转化成的xml文件中的${name}等格式没错误即可

表格的定义

遍历实现，表格的数据填充
在xml文件中我们的代表是我们的表格，代表的是我们的行，代表我们的列
我们要想使用表格的方式，肯定大部分是要使用我们的list集合进行数据填充的，我们可以通过下面的方式进行遍历填充数据
我们在表格的表头下的上添加

<#list TestList as item></#list>

图片的定义

首先我们要在指定位置添加一个图片，我们保存为xml文件后，我们的图片信心会变为base64转码的字符串，将这部分进行删除，替换为${images},所以我们进行填充时也要是base64转码后的数据

修改xml文件为ftl文件

最后将我们的文件修改为 .ftl 格式的文件复制到我们 templates文件夹下

2. 生成word文档

2.1 引入依赖

            org.freemarker        freemarker        2.3.30

2.2 代码实现

定义我们要填充的数据

  public Map<String,Object> dataMap() throws ioException {        //获取基础数据        Map<String , Object> map = new HashMap<>();        map.put("name","Qtt");        map.put("age","25");         //获取表格数据        List<Map<String,Object>> bookList = new ArrayList<>();        for (int i = 0; i < 5; i++) {            Map<String, Object> map1 = new HashMap<>();            map1.put("month",i);            map1.put("income", i);            map1.put("expense", i +100);            bookList.add(map1);        }        map.put("bookList",bookList);         //获取图片流且进行base64转码        File file = new File("C:\\Users\\Administrator\\Desktop\\teacher\\01.jpg");        FileInputStream fileInputStream = new FileInputStream(file);        byte[] bytes = new byte[fileInputStream.available()];        fileInputStream.read(bytes);        BASE64Encoder base64Encoder = new BASE64Encoder();        String encode = base64Encoder.encode(bytes);        map.put("images",encode);        //关闭流        fileInputStream.close();                return map;    }

定义我们我们的填充方法

public void insertWord() throws IOException, TemplateException {      //定义我们的编码方式      Configuration configuration = new Configuration();      configuration.setDefaultEncoding("UTF-8");      //指定我们word的目录      configuration.setDirectoryForTemplateLoading(new File("src/main/resources/templates"));      //指定我们要使用的word模板.ftl      Template template = configuration.getTemplate("testModel.ftl", "UTF-8");      //指定输出流到的位置      BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("E:/222/demo.doc"), "UTF-8"));      //执行填充输出      template.process(this.dataMap(),bufferedWriter);      //关闭io流      bufferedWriter.flush();      bufferedWriter.close();  }

我们还可以直接定义为下载，不用使用输出流指定下载地址，直接通过下载的方式指定地址

@GetMapping("/upload")   public void upload(httpservletResponse response){       try {           //定义我们的编码方式           Configuration configuration = new Configuration();           configuration.setDefaultEncoding("UTF-8");           //指定我们word的目录           configuration.setDirectoryForTemplateLoading(new File("src/main/resources/templates"));           //指定我们要使用的word模板.ftl           Template template = configuration.getTemplate("testModel.ftl", "UTF-8");           //返回word文档           SimpleDateFORMat simpleDateFormat = new SimpleDateFormat("yyyyMMddHHmmss");           String format = simpleDateFormat.format(new Date());           String fileName = URLEncoder.encode("接口文档" + format, "UTF-8");           response.setCharacterEncoding("UTF-8");           //请求头定义为下载           response.setHeader("Content-Disposition","attachment;filename="+fileName+".doc");           //获取apiDoc所需要的数据           Map<String, Object> map = dataMap();           //渲染模板           template.process(map, response.getWriter());           //response的Writer不需要我们手动关，Tomcat会帮我们关的       } catch (Exception e) {           log.error("导出word异常：", e);       }   }

注意:
1.优为注意：freemarker是不支持 null 的，所以我们的数据要么全部附上值，要么给为空的值设置为 " " ,否则会报错
2.我们在定义表格l遍历填充的时候，一定要注意传入的表格字段类型是list，不能是map，否则会报错

3. java后台生成柱状图图片并存到本地

3.1 引入依赖

            cn.hutool    hutool-all    5.6.2    org.jfree    jfreechart    1.5.3

3.2 系统字体

复制一下, 粘贴到项目中

3.3 默认字体位置
