Spring Boot 整合 Thymeleaf 模板和 iText 或者 Flying Saucer 等库可以方便地将 HTML 内容转换成 PDF 文件,包括面单标签。以下是一个简要步骤:
1. 添加依赖:首先,在Spring Boot项目的`pom.xml`文件中添加HTML转PDF相关的依赖,如iText或Flying Saucer。例如:
```xml
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itextpdf</artifactId>
</dependency>
<dependency>
<groupId>org.xhtmlrenderer</groupId>
<artifactId>flying-saucer-pdf</artifactId>
</dependency>
```
2. 创建HTML模板:使用Thymeleaf编写包含面单标签的HTML模板,比如`template.html`:
```html
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>面单模板</title>
</head>
<body>
<table th:fragment="invoice" class="invoice">
<!-- 面单内容 -->
<tr><td>订单号:</td><td th:text="${orderId}"></td></tr>
<!-- ...更多面单字段... -->
</table>
</body>
</html>
```
3. 编写Controller处理逻辑:在Spring Boot的控制器类中,注入模板引擎并渲染HTML到流:
```java
@GetMapping("/generate-pdf")
public ResponseEntity<InputStreamResource> generatePdf(@ModelAttribute("model") InvoiceModel model) {
try {
// 使用模板引擎
String template = "template.html";
Context context = new Context();
context.setVariable("orderId", model.getOrderId());
// ... 其他变量映射
InputStream inputStream = new ClassPathResource(template).getInputStream();
IEngine engine = new SaucierEngine(inputStream);
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
engine.process(context, outputStream);
return ResponseEntity.ok().contentType(MediaType.valueOf("application/pdf")).body(new InputStreamResource(outputStream));
} catch (Exception e) {
throw new RuntimeException(e);
}
}
```
