提交multipart/form-data类型数据

@(spring mvc)[文件上传|附加信息]

举例:

工行签名证书上传保存


说明:

框架使用的是spring mvc 4,接口测试工具使用postman,本文要实现的功能有:


  • 文件上传

    :文件上传信息填写在form-data区域,字段名即文件名,文件内容通过

    postman

    控件选择,存储在

    mysql

    数据库中类型为BLOB,对应的java类属性为byte[]

  • 文件存储

    :直接将文件存储到数据库,而非存储文件的URL;

  • 其他信息

    :同时上传文件的其他附加信息,也一并保存到数据库。

postman测试请求
