  配制一个applicationContext.XML如下
   
  ? xml version = " 1.0 "  encoding = " UTF-8 " ? 
   ! DOCTYPE beans PUBLIC  " -//SPRING//DTD BEAN//EN "   " http://www.springframework.org/dtd/spring-beans.dtd "  
   
    beans  default - autowire = " autodetect "  
        import  resource = " classpath:conf/spring/demo.xml "   / 
        bean id = " DataSource "   class = " org.apache.commons.dbcp.BasicDataSource "   
            property name = " driverClassName "   
                value  com.mysql.jdbc.Driver / value   
           / property   
            property name = " url "   
                value  jdbc:mysql: // 192.168.1.10:3306/test?characterEncoding=UTF-8&characterSetResults=UTF-8/value 
            / property  
            property name = " username "  
                value  root / value  
           / property  
            property name = " passWord "  
                value  xx / value  
           / property  
            property name = " maxActive "  
                value  10 / value  
           / property  
            property name = " maxIdle "  
                value  2 / value  
           / property  
       / bean  
        bean id = " TransactionManager " 
           class = " org.springframework.jdbc.datasource.DataSourceTransactionManager "  
            property name = " dataSource "  
  
                   ref bean = " DataSource "   / 
           / property  
       / bean  
        bean id = " JdbcTemplate " 
           class = " org.springframework.jdbc.core.JdbcTemplate "  
            property name = " dataSource "  
                ref bean = " DataSource "   / 
           / property  
       / bean  
   / beans  
  对应的TestDaoImpl中加入这部分代码
       private  JdbcTemplate jdbcTemplate;
      
       public  JdbcTemplate getJdbcTemplate()   {
           return  jdbcTemplate;
      } 
        public   void  setJdbcTemplate(JdbcTemplate jdbcTemplate)   {
           this .jdbcTemplate  =  jdbcTemplate;
      } 
       // 插入,修改和删除类似 
       String sql1  =   " insert into testdb1 values('1','2') " ;
      jdbcTemplate.update(sql1);
       // 查询 
         private   class  BeanRowMapper  implements  RowMapper   {
           public  Object mapRow(ResultSet rs,  int  rowNum)  throws  SQLException   {
              String id  =  rs.getString( " ID " );
              String title  =  rs.getString( " TITLE " );
              Bean bean  =   new  Bean(id,title);
               return  bean;
          } 
      } 
      String sql1  =   " select *  from testdb1  " ;
      List list  =  jdbcTemplate.query(sql1,  new  BeanRowMapper());
       // call back    (回调) 
        jt.execute( new  ConnectionCallback()  {
           public  Object doInConnection(Java.sql.Connection con)  throws  SQLException, DataAccessException   {
  
                  return   null ;
          } 
      } );
