運行.sql文件使用java代碼

Question

我有一個包含過程和插入語句的abc.sql文件。我怎樣才能運行腳本（abc.sql文件）使用java代碼而不使用腳本運行器API。

Answer 1

使用ProcessBuilder。在示例代碼下面，我運行select查詢並在控制檯中輸出結果。

public class RunOracleSql { 
    public static void main(String[] args) { 
     final String fileExtension = ".sql"; 
     String script_location = "C:/SQLFileLocation"; 
     try { 
      File file = new File("C:/SQLFileLocation"); 
      File[] listFiles = file.listFiles(new FileFilter() { 

       public boolean accept(File f) { 
        if (f.getName().toLowerCase().endsWith(fileExtension)) 
         return true; 
        return false; 
       } 
      }); 
      for (int i = 0; i < listFiles.length; i++) { 
       script_location = "@" + listFiles[i].getAbsolutePath();// ORACLE 
       ProcessBuilder processBuilder = new ProcessBuilder("sqlplus", 
         "username/password@database_name", script_location); // ORACLE 

       processBuilder.redirectErrorStream(true); 
       Process process = processBuilder.start(); 
       BufferedReader in = new BufferedReader(new InputStreamReader(
         process.getInputStream())); 
       String currentLine = null; 
       while ((currentLine = in.readLine()) != null) { 
        System.out.println(" " + currentLine); 
       } 
      } 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } catch (Exception ex) { 
      ex.printStackTrace(); 
     } 
    } 
}
