java spring boot 配置静态目录

package com.ggfw.datamanagement.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;


@Configuration
public class WebConfig implements WebMvcConfigurer {

    static final String EXCEL_PATH = System.getProperty("user.dir") + "/excelExport/";

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/excelExport/**").addResourceLocations("file:" + EXCEL_PATH);
    }
}

这样配置后根目录下的excelExport就会变成静态目录，可以通过http://localhost:post/excelExport来访问，

生成jar包后，与jar包同目录就会变成根目录同样可以访问，解决后端生成某些文件如导出excel后无法通过静态资源路径下载的问题
