|
||||
- 包含:排名、姓名、单位、各裁判评分、最终得分、奖牌
|
||||
- 支持筛选和排序
|
||||
|
||||
#### 实现要点
|
||||
```java
|
||||
// MartialResultServiceImpl.java
|
||||
public void exportScoreSheet(Long projectId, HttpServletResponse response) {
|
||||
// 1. 查询数据
|
||||
List<MartialResult> results = this.list(
|
||||
new QueryWrapper<MartialResult>()
|
||||
.eq("project_id", projectId)
|
||||
.orderByAsc("ranking")
|
||||
);
|
||||
|
||||
// 2. 构建导出数据
|
||||
List<ScoreExportVO> exportData = results.stream()
|
||||
.map(this::buildExportVO)
|
||||
.collect(Collectors.toList());
|
||||
|
||||
// 3. 使用EasyExcel导出
|
||||
try {
|
||||
response.setContentType("application/vnd.ms-excel");
|
||||
response.setCharacterEncoding("utf-8");
|
||||
String fileName = URLEncoder.encode("成绩单", "UTF-8");
|
||||
response.setHeader("Content-disposition", "attachment;filename=" + fileName + ".xlsx");
|
||||
|
||||
EasyExcel.write(response.getOutputStream(), ScoreExportVO.class)
|
||||
.sheet("成绩单")
|
||||
.doWrite(exportData);
|
||||
} catch (IOException e) {
|
||||
throw new ServiceException("导出失败");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### VO 定义
|
||||
```java
|
||||
@Data
|
||||
public class ScoreExportVO {
|
||||
@ExcelProperty("排名")
|
||||
private Integer ranking;
|
||||
|
||||
@ExcelProperty("姓名")
|
||||
private String playerName;
|
||||
|
||||
@ExcelProperty("单位")
|
||||
private String teamName;
|
||||
|
||||
@ExcelProperty("裁判1")
|
||||
private BigDecimal judge1Score;
|
||||
|
||||
@ExcelProperty("裁判2")
|
||||
private BigDecimal judge2Score;
|
||||
|
||||
@ExcelProperty("最高分")
|
||||
private BigDecimal maxScore;
|
||||
|
||||
@ExcelProperty("最低分")
|
||||
private BigDecimal minScore;
|
||||
|
||||
@ExcelProperty("平均分")
|
||||
private BigDecimal totalScore;
|
||||
|
||||
@ExcelProperty("难度系数")
|
||||
private BigDecimal coefficient;
|
||||
|
||||
@ExcelProperty("最终得分")
|
||||

|
||||
|
||||
@ExcelProperty("奖牌")
|

// 1. 查询成绩
|
||||
MartialResult result = this.getById(resultId);
|
||||
|
||||
// 2. 准备数据
|
||||
Map<String, Object> data = new HashMap<>();
|
||||
data.put("playerName", result.getPlayerName());
|
||||
data.put("projectName", "项目名称");
|
||||
data.put("ranking", result.getRanking());
|
||||
data.put("medal", getMedalName(result.getMedal()));
|
||||
|
||||
// 3. 使用FreeMarker渲染模板
|
||||
String html = freeMarkerService.process("certificate.ftl", data);
|
||||
|
||||
// 4. HTML转PDF
|
||||
ByteArrayOutputStream pdfStream = htmlToPdf(html);
|
||||
|
||||
// 5. 保存或返回
|
||||
savePdf(pdfStream, "certificate_" + resultId + ".pdf");
