Spring Boot 讀取 resource 下文件

支持linux下讀取

import org.springframework.core.io.ClassPathResource;
 
public byte[] getCertStream(String path) {
          try {
            ClassPathResource classPathResource = new ClassPathResource(path);
            //獲取文件流
            InputStream stream = classPathResource.getInputStream();
            byte[] content = IOUtils.toByteArray(stream);
            stream.read(content);
            stream.close();
　　　　　　　return content;
        } catch (IOException e) {
            e.printStackTrace();
        }
   }
