SpringBoot读取resources下的文件以及resources的资源路径

1.这种可以 但是在容器中获取不到（以下几种都可以只要不在容器）。

InputStream  inputStream = this.getClass().getResourceAsStream("/static/imgs/aha.png");

Properties pps = new Properties();
File file = ResourceUtils.getFile("classpath:defult.properties");
pps.load(new FileReader(file));

Properties pps = new Properties();
InputStream stream = getClass()
                    .getClassLoader()
                    .getResourceAsStream("defult.properties"); 
BufferedReader br = new BufferedReader(new InputStreamReader(stream, "UTF-8"));
pps.load(br);

//获取resources下文件夹路径
File directory = new File("../项目名/src/main/resources");
String reportPath = directory.getCanonicalPath();
String resource =reportPath+"\\files\\**";
//resource就是所需要的路径 eg: resource="D:\项目名\src\main\resources\files\****"

2.容器和服务器中都可以获取

import cn.hutool.core.io.resource.ResourceUtil;
//用hutool工具包的ResourceUtil
public static InputStream getTemplateXslmAsStream() throws IOException {
        return ResourceUtil.getStream("templates/gojob/excel/job_define.xlsm");
    }
