springboot中實現檔案上傳的具體步驟

首先是shiro許可權管理，要配置檔案上傳***

//upload檔案上傳

filterrulemap.put("/upload/**", 「anon」);

@configuration

public
class
shiroconfig/*
** 注入 securitymanager
** @return the security manager
*/@bean
public securitymanager securitymanager()
@bean
public customrealm customrealm()
/**     * 開啟shiro aop註解支援. 使用**方式; 所以需要開啟**支援;
** @param securitymanager 安全管理器
* @return 授權advisor
*/@bean
public authorizationattributesourceadvisor authorizationattributesourceadvisor
(securitymanager securitymanager)
}

registry.addresourcehandler("/driver/**").addresourcelocations(「file:」+filepath+"/upload/driver/");

@configuration

public
class
fileconfig
extends
webmvcconfigureradapter")
private string filepath;
@override
public
void
addresourcehandlers
(resourcehandlerregistry registry)
}

@restcontroller

("/filelibrary"
)@api
(tags =
"檔案管理"
)public
class
filelibrarycontroller
extends
basecontroller
("/editdriver"
)@apioperation
("司機證件修改"
)public object editdriver
(filelibrary filelibrary, multipartfile file)
else
string url = filelibraryservice.
uploadfile
(file, fileprefix, filepathkeyword, urlpathkeyword)
;        filelibrary.
setformername
(filename)
;        filelibrary.
seturl
(url)
;return filelibraryservice.
updatebyid
(filelibrary)
? resultjson.ok(
):resultjson.
failure
(resultcode.bad_request);}
}

public

@service

*/@override
public string uploadfile
(multipartfile file, string fileprefix, string filepathkeyword, string urlpathkeyword)
//檔案儲存路徑

string path = files + file.separator + targetname;
trycatch

string url =

;return url;
}/**

*/@override
public string deletefile
