在Jdbc类中，我首先需要运行两个方法，一个方法需要成功执行并将所有数据插入数据库，然后第二个方法应开始执行并将数据插入数据库。
我尝试了此处显示的代码，但是在完成第一种方法之前，代码将执行第二种方法：
public class dataTransfer extends DataAccess {
public static void main(String[] args) throws DataAccessException {
// TODO Auto-generated method stub
dailyOut(); // First Method to be done without going to next method
dailyIn(); // After writing all files in first mehod this method should write
}
public static void dailyOut()
{
Connection connection = null;
ResultSet rs = null;
String selectSQL = " SELECT * FROM all_reports WHERE report_id IN (SELECT report_id FROM daily_tmp_out )";
DataAccess bao = new DataAccess();
try {
connection = bao.getConnection();
PreparedStatement pstmt = connection.prepareStatement(selectSQL);
rs = pstmt.executeQuery();
ByteArrayOutputStream ous = null;
InputStream ios = null;
while (rs.next()) {
String filename = rs.getString("file_name");
String path = ("C:\\TEST\\" + filename );
File file = new File(path);
FileOutputStream output = new FileOutputStream(file);
Blob blob = rs.getBlob("file_data");
byte[] bytes1 = blob.getBytes(1l, (int) blob.length());
for (int i = 0; i < bytes1.length; i++) {
output.write(bytes1);
}
rs = pstmt.executeQuery("UPDATE all_reports set job_run= 'Y' where file_name =filename");
}
}
catch (Exception e) {
System.out.println(e.getMessage());
} finally {
try {
if (rs != null) {
rs.close();
}
} catch (SQLException e) {
System.out.println(e.getMessage());
}
}
}
public static void dailyIn()
{
Connection connection = null;
ResultSet rs = null;
String selectSQL = " SELECT * FROM all_reports WHERE report_id IN (SELECT report_id FROM daily_tmp_in)";
DataAccess bao = new DataAccess();
try {
connection = bao.getConnection();
PreparedStatement pstmt = connection.prepareStatement(selectSQL);
rs = pstmt.executeQuery();
ByteArrayOutputStream ous = null;
InputStream ios = null;
while (rs.next()) {
String filename = rs.getString("file_name");
String path = ("C:\\TEST\\In\\" + filename );
File file = new File(path);
FileOutputStream output = new FileOutputStream(file);
Blob blob = rs.getBlob("file_data");
byte[] bytes1 = blob.getBytes(1l, (int) blob.length());
for (int i = 0; i < bytes1.length; i++) {
output.write(bytes1);
}
rs = pstmt.executeQuery("UPDATE all_reports set job_run= 'Y' where file_name =filename");
}
} catch (Exception e) {
System.out.println(e.getMessage());
} finally {
try {
if (rs != null) {
rs.close();
}
} catch (SQLException e) {
System.out.println(e.getMessage());
}
}
}
}
我尝试的代码将转到第二种方法，而没有在第一种方法中完成所有插入操作，我想我错过了一些阻止执行第二种方法的功能。由于我是jdbc的新手，请给我建议和帮助以完成我的项目
