我有一个jLabel应该根据活动目录搜索输出计算机名称。计算机名称被分配给变量＆＃34; CN＆＃34;没问题，但除非我再次运行gui，否则它不会出现在jLabel上。如何让jLabel文本在gui的同一个实例中实时显示？ CN变量出现在所发布代码的底部。
StringBuffer sbuffer = new StringBuffer();
BufferedReader in = new BufferedReader(new InputStreamReader(p
.getInputStream()));
try {
while ((line = in.readLine()) != null) {
System.out.println(line);
// textArea.append(line);
String dn = "CN=FDCD111304,OU=Workstations,OU=SIM,OU=Accounts,DC=FL,DC=NET";
LdapName ldapName = new LdapName(dn);
String commonName = (String) ldapName.getRdn(
ldapName.size() - 1).getValue();
}
ComputerQuery.sendParam();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (InvalidNameException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} finally
{
try {
fw.close();
}
catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
try {
in.close();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
ComputerQuery.sendParam();
}
});
try (BufferedReader br = new BufferedReader(new FileReader("resultofbatch.txt")))
{
final Pattern PATTERN = Pattern.compile("CN=([^,]+).*");
try {
while ((sCurrentLine = br.readLine()) != null) {
String[] tokens = PATTERN.split(","); //This will return you a array, containing the string array splitted by what you write inside it.
//should be in your case the split, since they are seperated by ","
// System.out.println(sCurrentLine);
CN = sCurrentLine.split("CN=",-1)[1].split(",",-1)[0];
System.out.println(CN);
testLabel.setText(CN);
}
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
} catch (IOException e2) {
// TODO Auto-generated catch block
e2.printStackTrace();
}
新增代码
@Override
protected Integer doInBackground() throws Exception {
System.out.println(CN);
testLabel.setText(CN);
return null;
}
