Use Ibatis to manage ORACLE database!

three config file:config.propertis,SqlMapConfig_SE.xml,SqlMap_MDF.xml

config.properties: this file is config the propertis of the oracle database like port, password.......

oracle_port=1521
oracle_password=test
oracle_sid=orcl
oracle_user=test
oracle_server=172.16.113.228
timesten_dsn=bms_datafeedtest
reconnect_times=5

mail_smtp_host=mail.longtop.com
mail_smtp_port=25
mail_authenticator_username =xgdu
mail_authenticator_password =Dxg12345

default_serveraddr=127.0.0.1
default_port=9999

backup_serveraddr=127.0.0.1
backup_port=9999

SqlMapConfig_SE.xml: this file is setting the Ibatis ,this file have use config .properties to config some propertis

the follow is java file :MyConfig.java DBManager.java

MyConfig.java:this file is use java to config Ibatis

package org.lti;

import java.io.Reader;
import com.ibatis.common.resources.*;
import com.ibatis.sqlmap.client.SqlMapClient;
import com.ibatis.sqlmap.client.SqlMapClientBuilder;
public class MyConfig
{
 private static  SqlMapClient sqlMap;
 static
 {
  try
  {
   String resource="SqlMapConfig_SE.xml";
   Reader reader=Resources.getResourceAsReader(resource);
   sqlMap=SqlMapClientBuilder.buildSqlMapClient(reader);
  }
  catch(Exception e)
  {
   e.printStackTrace();
  }
 }
 public static SqlMapClient getSqlMapInstance()
 {
  return sqlMap;
 }
}

DBManager.java:this file is doing database operating

package org.lti;

import java.util.HashMap;
import com.ibatis.sqlmap.client.SqlMapClient;
public class DBManager
{
 public static void main(String[] args) throws Exception
 {
  // TODO Auto-generated method stub
  queryDB(3);
  updateDB(2,"lucy","lti");
  insertDB(8,"talent","guangzhou");
  deleteDB(8);
 }
 //query the table
 public static void queryDB(int i)throws Exception
 {
  SqlMapClient sqlMap=MyConfig.getSqlMapInstance();
  HashMap p=new HashMap();
  p=(HashMap)sqlMap.queryForObject("queryPerson",i);
  System.out.println("the NO   is "+p.get("NO"));
  System.out.println("the NAME is "+p.get("NAME"));
  System.out.println("the ADDR is "+p.get("ADDR"));
 }
 //update the table
 public static void updateDB(int no,String name,String addr)throws Exception
 {
  SqlMapClient sqlMap=MyConfig.getSqlMapInstance();
  HashMap p=new HashMap();
  p.put("NO",no);
  p.put("NAME",name);
  p.put("ADDR",addr);
  sqlMap.update("updatePerson",p);
 }
 //insert the table
 public static void insertDB(int no,String name,String addr)throws Exception
 {
  SqlMapClient sqlMap=MyConfig.getSqlMapInstance();
  HashMap p=new HashMap();
  p.put("NO", no);
  p.put("NAME",name);
  p.put("ADDR",addr);
  sqlMap.update("insertPerson",p);
 }
 //delete the table
 public static void deleteDB(int i)throws Exception
 {
  SqlMapClient sqlMap=MyConfig.getSqlMapInstance();
  sqlMap.delete("deletePerson",i);
 }
}
