Spring JDBC模板基本操作示例
Spring使用JdbcTemplate操作数据库首先,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:

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 insertPersonUseUp
