JSON 转换为 Word 文档
以下是一个在 Spring Boot 中实现 JSON 转 Word 的示例:
-
首先,需要在项目中引入相关的依赖,如
json
和Apache POI
等。在pom.xml
文件中添加以下内容:<!-- JSON 相关依赖 --> <dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.13.3</version> </dependency><!-- Apache POI 相关依赖 --> <dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>5.2.3</version> </dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>5.2.3</version> </dependency>
-
创建一个 Java 类,用于将 JSON 转换为 Word 文档,以下是示例代码:
import com.fasterxml.jackson.databind.ObjectMapper; import org.apache.poi.xwpf.usermodel.XWPFDocument; import org.apache.poi.xwpf.usermodel.XWPFParagraph; import org.springframework.http.ResponseEntity; import org.springframework.web.bind.annotation.*;import java.io.ByteArrayOutputStream; import java.io.IOExceptionimport;java.util.Map;@RestController @RequestMapping("/json-to-word") public class JsonToWordController {@PostMappingpublic ResponseEntity<byte[]> jsonToWord(@RequestBody Map<String, Object> json) throws IOException {// 创建一个 Word 文档XWPFDocument document = new XWPFDocument();// 创建一个新的段落XWPFParagraph paragraph = document.createParagraph();// 设置段落的文本内容为 JSON 的字符串形式paragraph.createRun().setText(new ObjectMapper().writeValueAsString(json));// 将 Word 文档转换为字节数组ByteArrayOutputStream outputStream = new ByteArrayOutputStream();document.write(outputStream);byte[] wordBytes = outputStream.toByteArray();// 设置响应头,指定内容类型为 Word 文,并档设置文件名return ResponseEntity.ok().header("Content-Type", "application/vnd.openxmlformats-officedocument.wordprocessingml.document").header("Content-Disposition", "attachment; filename=generated-word.docx").body(wordBytes);} }
