1.InputStream转String
public String downloadFile(CommonsMultipartFile testfile) throws IOException {
String filecontent = "";
if (testfile != null && !testfile.isEmpty()) {// 如果有文章中带有附件
String filename = testfile.getOriginalFilename();
InputStream is = null;// 附件输入流
try {
is = testfile.getInputStream();
System.out.println("is length:"+is.available());
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + " ");
}
filecontent = sb.toString();
System.out.println("filecontent:"+filecontent);
} catch (IOException exception) {
exception.printStackTrace();
} finally {
if (is != null) {
is.close();
}
}
return filecontent;
}
return filecontent;
}
2.文件上传：
vm文件：
<label class="form-labeler control-label">测试部署单</label>
<div class="form-content" method="post" >
<input id="oaFile" name="file" type="file" style="margin:10px;">
</div>
form表单中增加：
<form id="form" name="form" class="form-horizontal" method="post" action="setOddiffJob.htm" enctype="multipart/form-data" >
controller：
上传文件：
public String downloadFile(CommonsMultipartFile testfile，String destDir) throws IOException {
String filecontent = "";
if (testfile != null && !testfile.isEmpty()) {// 如果有文章中带有附件
String filename = testfile.getOriginalFilename();
System.out.println("filename:" + filename);
filecontent = destfileDir + filename;
DataOutputStream out = new DataOutputStream(new FileOutputStream(filecontent));// 存放文件的绝对路径
InputStream is = null;// 附件输入流
try {
is = testfile.getInputStream();
byte[] b=new byte[is.available()];
is.read(b);
out.write(b);
}
filecontent = sb.toString();
System.out.println("filecontent:"+filecontent);
} catch (IOException exception) {
exception.printStackTrace();
} finally {
if (is != null) {
is.close();
}
if (out != null) {
out.close();
}
}
return filecontent;
}
return filecontent;
}
@RequestMapping(value = "/tool/setOddiffJob")
public String setOddiffJob(@RequestParam("file") CommonsMultipartFile[] files, HttpServletRequest request,
Model model) throws Exception {
String onlineFile = downloadFile(files[0]);//按顺序读取文件
request.getParameter("appName");//读取表单中其他元素
}
3.java运行scp命令：
Connection conn = new Connection("10.218.146.27");
conn.connect();
conn.authenticateWithPassword("name", "passwd");//设置用户名和密码
// 建立SCP客户端
SCPClient scpClient = conn.createSCPClient();
// 将本地文件上传到服务器端的目录下
String onlinedestDir = "/home/admin";
File onlineDestDir = new File(onlinedestDir);
if(!onlineDestDir.isDirectory()){//判断路径是否存在，不存在就创建
onlineDestDir.mkdir();
}
scpClient.put(onlineFile, onlinedestDir);//上传文件到远程服务器
conn.close();
