报错功能描述：
将token_id的值更新到class下bppm.properties（普通文件）文件中。
系统在执行完如下代码后会重启，Java代码如下：
Properties prop = new Properties(); try { String realPathSRC = PropertiesUtil.class.getClassLoader().getResource("/").getPath(); //判断文件是否存在，如果存在将属性及值取得放到Properties，关闭文件流 File file = new File(realPathSRC + "bppm.properties"); if (!file.exists()) file.createNewFile(); InputStream fis = new FileInputStream(file); prop.load(fis); fis.close();// 一定要在修改值之前关闭fis OutputStream fos = new FileOutputStream(PropertiesUtil.class.getClassLoader().getResource(PROPERTY_FILE).getPath()); prop.setProperty("TOKEN_ID", "tokenID"); prop.store(fos, ""); fos.close(); } catch (Exception e) { e.printStackTrace(); }
代码中红色部分代码注释掉后，系统运行正常不报错，不重启。

你 好我也遇到了相同的问题，修改properties 后，tomcat 直接就挂掉了 自动重起，调式进去，也没有看出为什么会这样。
