Spring使用JdbcTemplate操作数据库---使用RowMapperResultSetExtractor读数据篇

首先建立数据表：

CREATE TABLE `login` (
  `username` varchar(10) default NULL,
  `passwd` varchar(10) default NULL,
  `address` varchar(10) default NULL
) ENGINE=InnoDB DEFAULT CHARSET=gb2312;

 

配置文件：

 

<? xml version="1.0" encoding="UTF-8" ?>
<! DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"  >
< beans >
  < 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://localhost:3306/javaee </ value >
    </ property >
    < property  name ="username" >
      < value > root </ value >
    </ property >
    < property  name ="password" >
      < value > 1234 </ value >
    </ property >
  </ bean >
  < bean  id ="jdbcTemplate"  class ="org.springframework.jdbc.core.JdbcTemplate" >
    < property  name ="dataSource" >
      < ref  local ="dataSource" />
    </ property >
  </ bean >

< bean  id ="personDAO"  class ="SpringJDBCSupport.ReadData.PersonDAO" >
   < property  name ="jdbcTemplate"
