二、在SpringBoot中就需要把上面配置到Spring的配置文件中的CommonsMultipartResolver配置到启动项的配置中去（ps：SpringBoot还不是很熟），Controller代码不变。

@Configuration
@ImportResource(locations = { "classpath:applicationContext.xml"})
//exclude表示自动配置时不包括Multipart配置
@EnableAutoConfiguration(exclude = {MultipartAutoConfiguration.class})
@ComponentScan
@SpringBootApplication
@ServletComponentScan(value={"com.xunlei","cn.xunlei","cn.xunlei.cbase.xlalarm"})
public class xlalarmApplication {

	public static void main(String[] args) {
		SpringApplication.run(xlalarmApplication.class, args);
	}
	
    //显示声明CommonsMultipartResolver为mutipartResolver
    @Bean(name = "multipartResolver")
       public MultipartResolver multipartResolver(){
        CommonsMultipartResolver resolver = new CommonsMultipartResolver();
        resolver.setDefaultEncoding("UTF-8");
//        resolver.setResolveLazily(true);//resolveLazily属性启用是为了推迟文件解析，以在在UploadAction中捕获文件大小异常
        resolver.setMaxInMemorySize(40960);
        resolver.setMaxUploadSize(10*1024*1024);//上传文件大小 10M 10*1024*1024
        return resolver;
    }   
	

}
