springboot重复使用MultipartFile

以下是两种在SpringBoot中重复使用MultipartFile的方法：

1. 在启动类中排除SpringBoot依赖，然后写一个配置文件UploadConfig，如下所示：

@SpringBootApplication(exclude = {MultipartAutoConfiguration.class})
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

@Configuration
public class UploadConfig {
    @Bean(name="multipartResolver")
    public MultipartResolver multipartResolver(){
        return new CommonsMultipartResolver();
    }
}

2. 在SpringBoot启动类中加入以下代码：

@SpringBootApplication
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @Bean(name = "multipartResolver")
    public CommonsMultipartResolver multipartResolver() {
        CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
        return multipartResolver;
    }
}
