1、如何自定义springmvc配置
旧的springmvc配置文件

第一种方式java版本

package cn.itcast.springboot.demo;

import java.nio.charset.Charset;

import javax.servlet.MultipartConfigElement;

import org.springframework.boot.web.servlet.MultipartConfigFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.StringHttpMessageConverter;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

import cn.itcast.springboot.demo.intercept.Intercept1;

@Configuration
public class SpringMvcConfigure extends WebMvcConfigurerAdapter{

    /**
     * 对转向页面的路径解析 
     * 2018年4月15日
     * @return
     */
    @Bean
    public InternalResourceViewResolver viewResolver(){
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/pages/");
        viewResolver.setSuffix(".jsp");
        // viewResolver.setViewClass(JstlView.class); // 这个属性通常并不需要手动配置，高版本的Spring会自动检测
        return viewResolver;
    }

    /**  
     * 文件上传配置  
     * @return  
     */  
    @Bean  
    public MultipartConfigElement multipartConfigElement() {  
        MultipartConfigFactory factory = new MultipartConfigFactory();  
        //文件最大  
        factory.setMaxFileSize("10240KB"); //KB,MB  
        /// 设置总上传数据总大小  
        factory.setMaxRequestSize("102400KB");  
        return factory.createMultipartConfig();  
    }  

    /**
     * 消息转换器配置
     * 2018年4月15日
     * @return
     */
    @Bean
    public StringHttpMessageConverter stringHttpMessageConverter(){
        return  new StringHttpMessageConverter(Charset.forName("UTF-8"));
    }

    /**
     * 拦截器配置
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new Intercept1()).addPathPatterns("/**");
    }


}

第二种方式配置文件
在application.properties

spring.mvc.view.prefix= # Spring MVC view prefix.
spring.mvc.view.suffix= # Spring MVC view suffix.

spring.http.multipart.maxFileSize=10Mb  
spring.http.multipart.maxRequestSize=10Mb
