java執行sql文件這個問題麻煩的地方在於解析sql腳本文件。所幸的是ant與 ibatis提供了這種實現。



 

package com.unmi;   
import java.io.*;   
import org.apache.tools.ant.*;   
import org.apache.tools.ant.taskdefs.*;   
import org.apache.tools.ant.types.*;  
/**  
* 調用 ant.jar 的 SQLExec 執行 SQL 腳本文件  
* @author Unmi  
*/  
public class AntExecSql {  
/**  
* @param args  
*/  
public static void main(String[] args) {   
SQLExec sqlExec = new SQLExec();   
//設置數據庫参數   
sqlExec.setDriver("oracle.jdbc.driver.OracleDriver");   
sqlExec.setUrl("jdbc:oracle:thin:@10.128.x.x:1521:xxsid");  
sqlExec.setUserid("xxuser");   
sqlExec.setPassword("xxpass");   
//要執行的腳本   
sqlExec.setSrc(new File("src/data.sql"));  
//有出錯的語句該如何處理   
sqlExec.setOnerror((SQLExec.OnError)(EnumeratedAttribute.getInstance(   
SQLExec.OnError.class, "abort")));  
sqlExec.setPrint(true); //設置是否輸出  
//輸出到文件 sql.out 中；不設置該屬性，默認輸出到控制台   
sqlExec.setOutput(new File("src/sql.out"));   
sqlExec.setProject(new Project()); // 要指定這個屬性，不然會出錯   
sqlExec.execute();   
}   
}  
package com.unmi;
import java.io.*;
import org.apache.tools.ant.*;
import org.apache.tools.ant.taskdefs.*;

ibatis：
package com.ibatis.jpetstore.test;
import java.sql.DriverManager;
import java.util.Properties;
import com.ibatis.common.jdbc.ScriptRunner;
import com.ibatis.common.resources.Resources;
import com.mysql.jdbc.Connection;
public class DBTestSQL {
 
 public static void main(String[] args) {
  
  try {
   Properties props = Resources.getResourceAsProperties("properties/database.properties");
   String url = props.getProperty("url");
   String driver = props.getProperty("driver");
   String username = props.getProperty("username");
   String password = props.getProperty("password");
   System.out.println(url);
   if(url.equals("jdbc:mysql://localhost:3306/jpetstore1")) {
    Class.forName(driver).newInstance();
    Connection conn = (Connection) DriverManager.getConnection(url, username, password);
    ScriptRunner runner = new ScriptRunner(conn, false, false);
    runner.setErrorLogWriter(null);
    runner.setLogWriter(null);
    runner.runScript(Resources.getResourceAsReader("ddl/mysql/jpetstore-mysql-schema.sql"));
    runner.runScript(Resources.getResourceAsReader("ddl/mysql/jpetstore-mysql-dataload.sql"));
    
   }
   
  } catch (Exception e) {
   e.printStackTrace();
  }
  
 }
}
 
 
ScriptRunner(com.ibatis.common.jdbc.*)用法
ScriptRunner類用於執行SQL語句,例如創建數據庫schema，或傳入缺省或測試數據庫等等。 從下面的例子可以認識到它的易用性:
    例子1：使用現成的數據庫連接
   Connection conn=getConnection();//some method to get a Connection
  ScriptRunner runner=new ScriptRunner();
  runner.runScript(conn,Resources.getResourceAsReader("com/some/resource/path/initialize.sql"));
   conn.close();
  例子2：使用新的數據庫連接
  ScriptRunner runner=new ScriptRunner("com.some.Driver","jdbc:url://db","login","password");
  runner.runScript(conn,new FileReader("/user/local/db/scripts/initialize-db.sql"));
例子3：使用新創建的數據連接
  Properties props= getProperties();//some properties form somewhere
ScriptRunner runner =new ScriptRunner(props);
runner.runScript(conn,new FileReader("/user/local/db/scripts/in
