实现效果
功能需求
要求照片部分，展示多张图片要求分析部分，一行文字加一张图片作为分析内容，并且可以展示多个分析结果要求比对部分，一行文字加两张对比图片展示，且展示多组比对结果
代码
实体类
// Test实体类，Set、Get略public class Test {private String date;private String site;private String param;private List<String> picture;private String measure;private List<AnalysisDto> analysisList;private List<CompareDto> compareDtoList;private String staff;}// 将分析部分的属性，作为一个实体类，Set、Get略public class AnalysisDto {private String analysis;private String analysisImg;public AnalysisDto(String analysis, String analysisImg) {this.analysis = analysis;this.analysisImg = analysisImg;}}// 比对部分的实体类，Set、Get略public class CompareDto {private String analysis;private String modePicture;private String resultPicture;public CompareDto(String analysis, String modePicture, String resultPicture) {this.analysis = analysis;this.modePicture = modePicture;this.resultPicture = resultPicture;}}
导出接口
public AjaxResult export(HttpServletRequest request, HttpServletResponse response) throws Exception {Test test = new Test();test.setDate("-06-10");test.setSite("厦门");test.setParam("模板测试");test.setPicture(Arrays.asList(FileUtils.encodeBase64File("whale.jpg"), FileUtils.encodeBase64File("whale2.jpg")));test.setMeasure("IDEA");test.setAnalysisList((new ArrayList<AnalysisDto>() {{add(new AnalysisDto("aaa", FileUtils.encodeBase64File("whale.jpg")));add(new AnalysisDto("bbb", FileUtils.encodeBase64File("whale1.jpg")));}}));test.setCompareDtoList(new ArrayList<CompareDto>() {{add(new CompareDto("ccc", FileUtils.encodeBase64File("whale.jpg"), FileUtils.encodeBase64File("猫耳.jpg")));add(new CompareDto("ddd", FileUtils.encodeBase64File("whale1.jpg"), FileUtils.encodeBase64File("whale2.jpg")));}});test.setStaff("测试人员");DocumentUtils documentUtils = new DocumentUtils();// 调用文件类里的模板导入方法documentUtils.exportTestWord(test,request,response).getInputStream();return AjaxResult.success();}

模板制作
xml
用office打开word，并插入文字和图片占位，另存为Word XML文档格式
ftl
用IDE打开xml文件，格式化文件后修改内容。
1.出现占位被分隔的情况的话，将中间的文字删除
2.将图片转码删除，改为占位符（单图片的情况直接改为占位符，多图片循环改为其他，详情见下）
3.将${property)替换为${Test.property},这里的Test为传入的Map的key。
4. 循环部分模板修改
单图片循环
图片带文字循环
文字带双图片循环同理
