微信企业号通讯录异步更新(java)

1. 需要将批量更新的内容写入CSV文件中。

	    String tmpDirUser = System.getProperty("java.io.tmpdir");
	    String fileNameUser =MessageFormat.format(CONTACT_CSV, corpId, suiteId);
	    logger.info(tmpDirUser + File.pathSeparator + fileNameUser);
	    
	    File tempUserFile = new File(tmpDirUser + File.pathSeparator + fileNameUser);

2. 这里给出一个将内容写入CSV文件工具类。
