Spring Boot 代码中生成 MultipartFile 对象

Spring Boot About 1,104 words

方法一(推荐)

使用CommonsMultipartFile

前提:Java9Spring

import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.springframework.web.multipart.commons.CommonsMultipartFile;

File file = new File("file.txt");
FileItem fileItem = new DiskFileItemFactory().createItem("file",
    Files.probeContentType(file.toPath()), false, file.getName());

try (InputStream in = new FileInputStream(file); OutputStream out = fileItem.getOutputStream()) {
    in.transferTo(out);
} catch (Exception e) {
    throw new IllegalArgumentException("Invalid file: " + e, e);
}

CommonsMultipartFile multipartFile = new CommonsMultipartFile(fileItem);

方法二

使用MockMultipartFile

前提:需要添加spring-boot-starter-test依赖,如果用于正常代码中,需要将scopetest的配置去掉。

添加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

代码

MultipartFile multipartFile = new MockMultipartFile("test.xlsx", new FileInputStream(new File("/home/admin/test.xlsx")));
