你可以使用Apache POI库来将Spring Boot文档转换为docx格式并输出为文件流。下面是一个示例代码:
```java
import org.apache.poi.xwpf.usermodel.*;
import org.springframework.core.io.InputStreamResource;
import org.springframework.http.HttpHeaders;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import java.io.ByteArrayOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
@RestController
public class DocxController {
@GetMapping(value = "/docx", produces = MediaType.APPLICATION_OCTET_STREAM_VALUE)
public ResponseEntity<InputStreamResource> generateDocx() throws IOException {
// 读取Spring Boot文档
FileInputStream inputStream = new FileInputStream("path/to/spring-boot-doc.doc");
XWPFDocument document = new XWPFDocument(inputStream);
// 创建输出流
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
// 写入docx内容
document.write(outputStream);
outputStream.close();
// 设置响应头
HttpHeaders headers = new HttpHeaders();
headers.add("Content-Disposition", "attachment; filename=spring-boot-doc.docx");
// 返回文件流
return ResponseEntity
.ok()
.headers(headers)
.contentType(MediaType.APPLICATION_OCTET_STREAM)
.body(new InputStreamResource(new ByteArrayInputStream(outputStream.toByteArray())));
}
public void saveDocx() throws IOException {
// 读取Spring Boot文档
FileInputStream inputStream = new FileInputStream("path/to/spring-boot-doc.doc");
XWPFDocument document = new XWPFDocument(inputStream);
// 创建输出流
FileOutputStream outputStream = new FileOutputStream("path/to/output.docx");
// 写入docx内容
document.write(outputStream);
outputStream.close();
}
}
```
你可以将以上代码放入Spring Boot项目中的控制器中,并访问`/docx`路径来生成并下载docx文件,或者调用`saveDocx()`方法将docx文件保存到指定路径。
请将代码中的`path/to/spring-boot-doc.doc`替换为实际的Spring Boot文档路径,`path/to/output.docx`替换为你希望保存输出文件的路径。
