以下是使用SpringBoot生成上传文件接口的步骤:
1.在pom.xml文件中添加依赖:
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- 文件上传依赖 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.4</version>
</dependency>
```
2.在application.properties文件中添加配置:
```properties
# 文件上传配置
spring.servlet.multipart.enabled=true
spring.servlet.multipart.max-file-size=10MB
spring.servlet.multipart.max-request-size=100MB
spring.servlet.multipart.file-size-threshold=0
```
3.创建一个Controller类,添加上传文件的接口:
```java
@RestController
@RequestMapping("/file")
public class FileController {
@PostMapping("/upload")
public String upload(@RequestParam("file") MultipartFile file) {
if (file.isEmpty()) {
return "上传失败,请选择文件";
}
String fileName = file.getOriginalFilename();
String filePath = "D:/upload/";
File dest = new File(filePath + fileName);
try {
file.transferTo(dest);
return "上传成功";
} catch (IOException e) {
e.printStackTrace();
}
return "上传失败!";
}
}
```
4.启动SpringBoot应用程序,并使用Postman等工具测试上传文件接口。
