HTTP工具类封装与http请求响应-CSDN博客
一、前言 在Java web系统中经常需要与外部接口进行对接,比较多的方式就是是http的方式。在springboot中,我们可以直接使用封装的feign如:我们去请求微信的接口,定义一个client客户端,使用feign框架去请求就可以。但是也有很多系统没有使用feign的框架,那就需要使用http工具类了。 @FeignClient(name = "weixin", url = "https://api.weixin.qq.com/") public interface WXCLient { /** * 获取微信token * @param appid * @param secret * @return */ @GetMapping("cgi-bin/token") Map<String, Object> gettoken(@RequestParam("appid") String appid, @RequestParam("secret") String secret, @RequestParam("grant_type") String grant_type); /**...

MultipartFile的属性 file.getOriginalFilename()与file.getName()的区别 MultipartFile与File互转
一、概述 MultipartFile为org.springframework.web.mutipart包下的一个类,也就是说如果想使用MultipartFile这个类就必须引入spring框架,换句话说,如果想在项目中使用MultipartFile这个类,那么项目必须要使用spring框架才可以,否则无法引入这个类。 以下基于spring-web.5.2.9.RELEASE源码了解一下MultipartFile MultipartFile注释说明 二、MultipartFile常用方法 首先MultipartFile是一个接口,并继承自InputStreamSource,且在InputStreamSource接口中封装了getInputStream方法,该方法的返回类型为InputStream类型,这也就是为什么MultipartFile文件可以转换为输入流。通过以下代码即可将MultipartFile格式的文件转换为输入流。 multipartFile.getInputStream(); 方法说明 String getName() 返回参数的名称,如(MultipartFile...
