spring boot 中 jar包中获取路径

问题

1. spring boot 打包后如何获取jar包的位置
2. spring boot 获取resources文件夹下面的文件

解答
1.jar包位置

ApplicationHome applicationHome = new ApplicationHome(this.getClass());
java.io.File file = applicationHome.getDir();
String route = file.getAbsolutePath();

2.获取resources文件下的文件

InputStream fd = ClassUtils.getDefaultClassLoader().getResourceAsStream("resources下文件路径");
BufferedReader br = new BufferedReader(new InputStreamReader(fd));
StringBuffer sb = new StringBuffer();
String readLine;
while ((readLine = br.readLine()) != null) {
  if (readLine.charAt(0) == '-') {
    continue;
  } else {
    sb.append(readLine + "
");
  }
}
