Question

我无法尝试让tnsname.ora文件执行以下操作：

I managed to get the JComboBox populated with the data from the service_name

My next question is the following:

一个。如果在JCombobox上选择了特定的service_name，如何填充CORRECT /适当的主机名（例如127.0.0.3）。

我。我知道这可以使用itemStateChanged（ItemEvent ie）完成，并且我可以使其动作，以便在选择不同的服务名称时填充数据。但问题是，如何做以下几点：

If the service_name equals a certain SID

一个。然后去填充存储的文本框：

我。宿主

II。端口

III。协议

我有自己的理论如何做到这一点，但不知道如何将其转换为Java代码：

如果选择了service_name
转到上一行（4步后退），其中填充了主机详细信息 - ＆GT;将主机数据填充到主机文本框
转到填充端口的上一行 - ＆GT;将端口数据填充到端口文本框

public void PopulateTnsNamesDropDownList() {
    Properties prop = new Properties();

    InputStream input2 = null;

    try {
        input2 = new FileInputStream("C:\\folder\\config.properties");

        try {
            prop.load(input2);
        } catch (IOException e) {
            e.printStackTrace();
        }

        String path = null;
        path = prop.getProperty("tnsnames_directory");

        BufferedReader input = new BufferedReader(new FileReader(path));

        List<String> strings = new ArrayList<String>();

        try {
            String line = null;

            try {
                while ((line = input.readLine()) != null) {
                    if (line.contains("(SERVICE_NAME =")) {
                        String service_name = null;
                        service_name = line.replaceAll("SERVICE_NAME = ", "").trim().replaceAll("\\(", "").replaceAll("\\)", "");

                        strings.add(service_name);
                    }
                }
            } catch (IOException e) {
                JOptionPane.showMessageDialog(Workers.this, "Error, configuration properties did not exist or not set correctly." + e.getMessage());
            }
        }

        finally {
            try {
                input.close();
            } catch (IOException e) {
                JOptionPane.showMessageDialog(Workers.this, "Error, configuration properties did not exist or not set correctly." + e.getMessage());
            }
        }
        String[] lineArray = strings.toArray(new String[] {});
        JComboBox comboBox = new JComboBox(lineArray);
        TnsNamesComboBox.setModel(new javax.swing.DefaultComboBoxModel(lineArray));
    } catch (FileNotFoundException e) {
        JOptionPane.showMessageDialog(Workers.this, "Error, configuration properties did not exist or not set correctly." + e.getMessage());
    }
}
