springboot项目base64上传图片

springboot项目base64上传图片

今天来分享一下自己的爬坑之路，图片上传分为MultipartFile上传和base64上传。今天只分享base64上传图片

配置路径

在application.properties文件中的配置如下

spring.servlet.multipart.maxFileSize=10Mb//最大上传文件
spring.servlet.multipart.maxRequestSize=10Mb//最小上传文件
file.uploadFolder=C:/file/  //上传的路径，此处因为本地测试服务器只有一个C盘
file.staticAccessPath=/file/  //回显路径

在文件中新建config包，在这个包下面新建WebConfiguration ，加注解**@Configuration**

package manage.config;

import java.util.concurrent.Executors;

import org.springframework.beans.factory.annotation.Value;

  @Override
     public void addCorsMappings(CorsRegistry registry) {

                 .allowedHeaders("*");
         super.addCorsMappings(registry);
     }
  
  //配置图片回显
  public void addResourceHandlers(ResourceHandlerRegistry registry) {
     
	  registry.addResourceHandler(staticAccessPath+"/**").addResourceLocations("file:" + uploadFolder+File.separator);
	// 解决静态资源无法访问
      registry.addResourceHandler("/**").addResourceLocations("classpath:/static/");
