在application.properties文件中设置发现没用，后来才用这个方法，原配置如下

# file Configuration
    spring.servlet.multipart.max-request-size=100Mb
    spring.servlet.multipart.max-file-size=100Mb

在application.java启动文件中配置，配置如下

@SpringBootApplication(exclude = QuartzAutoConfiguration.class)
    @Configuration
    public class ApplicationTest extends SpringBootServletInitializer {
    
    	@Override
    	protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    		return application.sources(ApplicationTest.class);
    	}
    
    	public static void main(String[] args) throws Exception {
    		SpringApplication.run(ApplicationTest.class, args);
    	}
    
    	@Bean
    	public MultipartConfigElement multipartConfigElement() {
    		MultipartConfigFactory factory = new MultipartConfigFactory();
                    // 以下方法springboot2.1.0之后过时
    		// factory.setMaxFileSize("51200KB"); //KB,MB
    		// factory.setMaxRequestSize("102400KB");
    
                    // 文件最大50M,DataUnit提供5中类型B,KB,MB,GB,TB
                    factory.setMaxFileSize(DataSize.of(50, DataUnit.MEGABYTES));
                    factory.setMaxRequestSize(DataSize.of(50, DataUnit.MEGABYTES));
    		return factory.createMultipartConfig();
    	}
    }

或者创建文件单独配置

package com.***.framework.config;
    
    import org.springframework.boot.web.servlet.MultipartConfigFactory;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    import javax.servlet.MultipartConfigElement;
    
    @Configuration
    public class MultipartConfig {
        @Bean
        public MultipartConfigElement multipartConfigElement(){
            MultipartConfigFactory factory = new MultipartConfigFactory();
            // 以下方法springboot2.1.0之后过时
            // factory.setMaxFileSize("50MB");
            // factory.setMaxRequestSize("50MB");
    
            // 文件最大50M,DataUnit提供5中类型B,KB,MB,GB,TB
            factory.setMaxFileSize(DataSize.of(50, DataUnit.MEGABYTES));
            factory.setMaxRequestSize(DataSize.of(50, DataUnit.MEGABYTES));
            return factory.createMultipartConfig();
        }
    }
