spring boot :The temporary uplo

解决办法

注入对象
@Bean
    MultipartConfigElement multipartConfigElement() {
        MultipartConfigFactory factory = new MultipartConfigFactory();
        factory.setLocation("E://tomcat_file/temp");
        return factory.createMultipartConfig();
    }

或者在配置文件中添加:

spring.http.multipart.location=E://tomcat_file/temp
