**2. Controller**

adminController增加添加房源页面映射、长传图片接口

@GetMapping("admin/add/house")
        public String adminHousePage() {
            return "admin/house-add";
        }
        /**
         * 上传图片接口
         * @param file
         * @return
         */
        @PostMapping(value = "admin/upload/photo", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
        @ResponseBody
        public ApiResponse uploadPhoto(@RequestParam("file") MultipartFile file) {
        
            if (file.isEmpty()) {
                return ApiResponse.ofStatus(ApiResponse.Status.NOT_VALID_PARAM);
            }
            
            String fileName = file.getOriginalFilename();
            
            return ApiResponse.ofSuccess(null);
        }

**3. Config**  
config包增加上传图片配置类WebFileUploadConfig

package com.xunwu.config;
    
    /**
     * 文件上传配置.
     */
    @Configuration
    @ConditionalOnClass({Servlet.class, StandardServletMultipartResolver.class, MultipartConfigElement.class})
    @ConditionalOnProperty(prefix = "spring.http.multipart", name = "enabled", matchIfMissing = true)
    @EnableConfigurationProperties(MultipartProperties.class)
    public class WebFileUploadConfig {
        private final MultipartProperties multipartProperties;
    
        public WebFileUploadConfig(MultipartProperties multipartProperties) {
            this.multipartProperties = multipartProperties;
        }
    
        /**
         * 上传配置
         */
        @Bean
        @ConditionalOnMissingBean
        public MultipartConfigElement multipartConfigElement() {
            return this.multipartProperties.createMultipartConfig();
        }
    
        /**
         * 注册解析器
         */
        @Bean(name = DispatcherServlet.MULTIPART_RESOLVER_BEAN_NAME)
        @ConditionalOnMissingBean(MultipartResolver.class)
        public StandardServletMultipartResolver multipartResolver() {
            StandardServletMultipartResolver multipartResolver = new StandardServletMultipartResolver();
            multipartResolver.setResolveLazily(this.multipartProperties.isResolveLazily());
            return multipartResolver;
        }
    }

application.properties  
注意windows下路径不同

# multipart config
    spring.http.multipart.enabled=true
    spring.http.multipart.location=E:\\tmp\\
    spring.http.multipart.file-size-threshold=5MB
    spring.http.multipart.max-request-size=20MB
