Spring-Boot的上传

发表于 更新于 分类于 ，

传参

前端用from表单提交，spring boot 参数已经通过拦截器做好了映射处理

文件上传配置

spring.servlet.multipart.max-request-size=500MB
spring.servlet.multipart.max-file-size=500MB

如果有覆盖总是最下面的生效

自定义配置文件

property.param.key=key
property.param.name=name

    private String name;
}

@EnableConfigurationProperties(FileProperties.class)

public class ServiceImpl implements MultipartFileService{
    private final FileProperties fileProperties;
    @Autowired
    @SuppressWarnings("SpringJavaAutowiringInspection")
    public MultipartFileServiceImpl(FileProperties fileProperties) {
        this.fileProperties = fileProperties;
    }

    public void test(){
        log.info(fileProperties.getKey+fileProperties.getName);
    }
}

private String saveFile(MultipartFile file,String fileType,String fileName){
    //读取配置文件，获取文件上传路径
    Path path= Paths.get(fileProperties.getUploadPath(fileType)+ fileName);
    File targetFile=path.toFile().getParentFile();
    if(!targetFile.exists()){
        targetFile.mkdirs();
    }
    try {
        byte[] bytes = file.getBytes();
        Files.write(path,bytes);
    }catch (Exception e){
        log.error(e.getMessage(),e);
        return null;
    }
    return path.toString();
}
