添加一个结果处理器，表示要对结果做点什么事情，比如此处使用print()：输出整个响应结果信息。：代表客户端希望接受的数据类型为application/json;：代表发送端发送的数据格式是application/json;：方法看请求的状态响应码是否为200如果不是则抛异常，测试不通过。：代表在报文头添加一些必须的信息，这里添加的是token。：构造一个请求，Post请求使用.post方法。mockMvc测试代码。：添加执行完成后的断言。

MultipartFile是spring类型，代表HTML中form data方式上传的文件，包含二进制数据+文件名称。使用MockMultipartFile but, 是使用的，需要导入。因为使用到了”spring-test.jar" 所以发现本地环境是可以的 原因是因为有spring-test这个包。 然而项目发布后发现项目启动不了一直报错找不到MockMultipartFile。 原因是发布正式版时，不会打测试包。找不到也很正常。根据源码，自己照搬重写一个 方法在项目里...

MockMultipartFile 是一个用于测试的模拟类，通常在单元测试或集成测试中模拟 MultipartFile 的行为。它属于 Spring 框架的测试包 org.springframework.mock.web 中的一部分，不应该在生产环境中使用。因此我们采用实现MultipartFile接口类的方式，自己实现转换逻辑。
