Spring使用JdbcTemplate操作数据库例子
首先，假设如下SQL表中有数据username=test1,passwd=test1,address=test1

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：

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd" >

</bean>

<bean id="personDAO" class="SpringJDBCSupport.ReadData.PersonDAO">
  <property name="jdbcTemplate">
    <ref local="jdbcTemplate"/>
  </property>
</bean>
</beans>







JavaBean:



package SpringJDBCSupport.ReadData;
import com.mysql.jdbc.Driver;
public class Person {
  private String name;
  private String password;
  private String address;
  public Person(){
     
  }
  public Person(String name,String password,String address){
      this.name=name;
      this.password=password;
      this.address=address;
  }
public String getAddress() {
    return address;
}
public void setAddress(String address) {
    this.address = address;
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public String getPassword() {
    return password;
}
public void setPassword(String password) {
    this.password = password;
}
public String toString(){
    return this.getName()+"-"+this.getPassword()+"-"+this.getAddress();
}
}



DAO：

其中getPersonByRowCallbackHandler方法根据username获得person对象

package SpringJDBCSupport.ReadData;

import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Types;
import java.util.List;

import org.springframework.jdbc.core.BatchPreparedStatementSetter;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.RowCallbackHandler;

public class PersonDAO {
  private JdbcTemplate jdbcTemplate;

public JdbcTemplate getJdbcTemplate() {
    return jdbcTemplate;
}

public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
    this.jdbcTemplate = jdbcTemplate;
}

public int insertPersonUseUpdate(Person person){
