springboot上传linux文件无法浏览，提示404错误

Posted 2021-01-21 liw66

1.配置文件地址置换

@Component
class WebConfigurer implements WebMvcConfigurer {
   @Autowired
   ConfigUtil bootdoConfig;
   @Override
   public void addResourceHandlers(ResourceHandlerRegistry registry) {
      registry.addResourceHandler("/files/**").addResourceLocations("file:///"+bootdoConfig.getUploadPath());
   }
}
2.配置工具类

@Component
@ConfigurationProperties(prefix="file")
public class ConfigUtil {
    //上传路径
    private String uploadPath;

　　public String getUploadPath() {
    　　return uploadPath;
　　}

　　public void setUploadPath(String uploadPath) {
    　　this.uploadPath = uploadPath;
　　}
}

3.js打开文件地址

var src = ‘/files/2018-11-16/*.png‘;

$("#viewDiv").empty();
var obj = $("<iframe src="+src+" width=‘99%‘ frameborder=‘0‘></iframe>");

if(document.documentElement.clientHeight != 0){
    obj.height(document.documentElement.clientHeight)
}

$("#viewDiv").append(obj);

3.Application.yml里面配置的上传路径
file:
  uploadPath: /www/server/*/uploaded_files

路径最后缺少一个/导致附件无法访问 改为

　uploadPath: /www/server/*/uploaded_files/

问题解决
