配制Spring事务和JdbcTemplate使用

配制一个applicationContext.xml如下
xml version = " 1.0 "  encoding = " UTF-8 " ?>
DOCTYPE beans PUBLIC  " -//SPRING//DTD BEAN//EN "   " " >

< 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
         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 ;
        }
    } );
