java 读取sql文件并且执行入库

java执行sql文件这个问题麻烦的地方在于解析sql脚本文件。所幸的是ant与 ibatis提供了这种实现。
 
package com.unmi;
import java.io.*;
import org.apache.tools.ant.*;
import org.apache.tools.ant.taskdefs.*;
import org.apache.tools.ant.types.*;
/**
* 调用 ant.jar 的 SQLExec 执行 SQL 脚本文件
* @author Unmi
*/
public class AntExecSql {
/**
* @param args
*/
public static void main(String[] args) {
SQLExec sqlExec = new SQLExec();
//设置数据库参数
sqlExec.setDriver("oracle.jdbc.driver.OracleDriver");
sqlExec.setUrl("jdbc:oracle:thin:@10.128.x.x:1521:xxsid");
sqlExec.setUserid("xxuser");
sqlExec.setPassword("xxpass");
//要执行的脚本
sqlExec.setSrc(new File("src/data.sql"));
//有出错的语句该如何处理
sqlExec.setOnerror((SQLExec.OnError)(EnumeratedAttribute.getInstance(
SQLExec.OnError.class, "abort")));
sqlExec.setPrint(true); //设置是否输出
//输出到文件 sql.out 中；不设置该属性，默认输出到控制台
sqlExec.setOutput(new File("src/sql.out"));
sqlExec.setProject(new Project()); // 要指定这个属性，不然会出错
sqlExec.execute();
}
}
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类用于执行SQL语句,例如创建数据库schema，或传入缺省或测试数据库等等。 从下面的例子可以认识到它的易用性:
    例子1：使用现成的数据库连接
   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：使用新的数据库连接
  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：使用新创建的数据连接
  Properties props= getProperties();//some properties form somewhere
ScriptRunner runner =new ScriptRunner(props);
runner.runScript(conn,new FileReader("/user/local/db/scripts/initialize-db.sql"));
