springboot图片上传，虚拟路径的配置

妖狐艹你老母 2023-06-30 09:06 6阅读 0赞

1.application.properties配置

#静态资源对外暴露的访问路径
    file.staticAccessPath=/upload/**
    #文件上传目录
    file.uploadFolder=D:/upload/

2.配置文件实体化

package com.example.demo.upload;
    
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.stereotype.Component;
    import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
    import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
    
    @Component
    @Configuration  
    
    @ConfigurationProperties(prefix="file") 
    
    public class UploadFilePathConfig implements WebMvcConfigurer {
    
        @Value("${server.port}")
        private String port;
        @Value("${file.staticAccessPath}")
        private String staticAccessPath;
        @Value("${file.uploadFolder}")
        private String uploadFolder;
    
        /**
         * 重写这个方法即可配置虚拟路径
         * @param registry
         */
        @Override
        public void addResourceHandlers(ResourceHandlerRegistry registry) {
            registry.addResourceHandler(staticAccessPath).addResourceLocations("file:" + uploadFolder);
        }
        public String getPort() {
            return port;
        }
        public void setPort(String port) {
            this.port = port;
        }
        public String getStaticAccessPath() {
            return staticAccessPath;
        }
        public void setStaticAccessPath(String staticAccessPath) {
            this.staticAccessPath = staticAccessPath;
        }
        public String getUploadFolder() {
            return uploadFolder;
        }
        public void setUploadFolder(String uploadFolder) {
            this.uploadFolder = uploadFolder;
        }
    }

`3.调用`

使用@autowired即可

此时访问的路径就是：http://localhost:8008/upload/图片名

# 注： #

# 这是一种图片上传访问图片的方法，也可以使用nginx反向代理访问图片 #
