<>1 获取当前项目所在路径
// 获取当前项目根路径 String dir = System.getProperty("user.dir");
<>获取resource 下静态资源路径
public static String getStaticPath(){ URL resource = Thread.currentThread().
getContextClassLoader().getResource("static"); assert resource != null; return
resource.getPath(); } public static String getStaticPath2(){ URL resource =
StaticUtil.class.getClassLoader().getResource("static"); assert resource != null
; return resource.getPath(); }
<>3 直接获取resource 下的资源
import org.springframework.core.io.ClassPathResource; import org.
springframework.core.io.Resource; // 获取resource 下的资源 Resource resource = new
ClassPathResource("license.xml"); System.out.println(resource.getURL().getPath()
);
<>4 注意（线上最好不要使用getResource）
使用getResource来读取resources文件夹下的文件,但是这个方法没有办法读取压缩文件里的路径,而jar本质来说是一个压缩包.所以在线上环境使用getResource时会报错
