springboot 运行 jar 包读取外部配置文件

public class Test{
    public String getData() throws IOException {
       //获取jar包同级目录 from fhadmin.cn
        String path = this.getClass().getProtectionDomain().getCodeSource().getLocation().getPath();
        String[] pathSplit = path.split("/");
        String jarName = pathSplit[pathSplit.length - 1];
        String jarPath = path.replace(jarName, "");
        String pathName=jarPath+"minhang.properties";
        System.out.println("配置文件路径："+jarPath);
        //读取配置文件
        Properties properties = new Properties();
        File file = new File(pathName);
        FileInputStream fis = new FileInputStream(file);
        properties.load(fis);
        fis.close();
        //获取配置文件数据
        String confData = properties.getProperty("confData");
        System.out.println(confData);
    }
}
