java创建log.html文件,其中我会在错误被捕获时将错误转储到html表行.
我创建了表列,但是当我向它传递任何内容时,我的数据将覆盖列名而不是追加行. 我的java代码如下: public static void main(String[] args) throws IOException { String month = getMonth(1); System.out.println(month); //table(month); addrow("abc"); } public static void table(String Update) throws IOException { //define a HTML String Builder StringBuilder htmlStringBuilder=new StringBuilder(); htmlStringBuilder.append("<html><head><title>Packaging Issues</title></head>"); htmlStringBuilder.append("<body><h1> Files Received </h1>"); htmlStringBuilder.append("<table border="1" bordercolor="#000000">"); htmlStringBuilder.append("<tr><td><b>Cycle</b></td><td>"+Update+"</td></tr>"); htmlStringBuilder.append("<tr><td><b>Version</b></td><td></tr>"); newtable(htmlStringBuilder.toString()); } public static void newtable(String a) { StringBuilder htmlStringBuilder=new StringBuilder(); htmlStringBuilder.append(a); htmlStringBuilder.append("<h1> Issues Found </h1>"); htmlStringBuilder.append("<table border="1" bordercolor="#000000">"); htmlStringBuilder.append("<tr><td><b>Type</b></td>"); htmlStringBuilder.append("<td><b>Field</b></td>"); htmlStringBuilder.append("<td><b>Issue</b></td></tr>"); addrow(htmlStringBuilder.toString()); // WriteToFile(htmlStringBuilder.toString(),"log.html"); } public static void addrow(String a) { try { StringBuilder htmlStringBuilder=new StringBuilder(); htmlStringBuilder.append("<tr><td><b>"+a+"</b></td>"); htmlStringBuilder.append("<td><b>Field</b></td>"); htmlStringBuilder.append("<td><b>Issue</b></td></tr>"); htmlStringBuilder.append("</table></body></html>"); WriteToFile(htmlStringBuilder.toString(),"log.html"); } catch (IOException e) { e.printStackTrace(); } } 这是writetofile方法: public static void WriteToFile(String fileContent,String fileName) throws IOException { String projectPath = "/home/abc"; String tempFile = projectPath + File.separator+fileName; File file = new File(tempFile); // if file does exists,then delete and create a new file //write to file with OutputStreamWriter OutputStream outputStream = new FileOutputStream(file.getAbsoluteFile()); Writer writer=new OutputStreamWriter(outputStream); writer.write(fileContent); writer.close(); } 如果还有其他办法,请分享.谢谢你的支持 解决方法
构造函数FileOutputStream(file)会覆盖文件的内容.请改用
this constructor
FileOutputStream fos =new FileOutputStream(file,true) ; (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
