实体类：略

接口类

package com.xdl.dao;

import java.util.List;

import com.xdl.bean.BankAccount;


public interface BankAccountDAO {
     List  listBankAccount();
     /** 根据账号 删除账户 */
     int   deteleAccountByAno(String ano);
     /** 根据账号 查询账户 */
     BankAccount   getAccountByAno(String ano);
     /** 插入银行账户数据 */
     int   insertAccount(BankAccount  account);
     /** 更新方法 */
     int   updateAccount(BankAccount  account);

}

mapper映射器：

package com.xdl.mapper;


import java.sql.ResultSet;
import java.sql.SQLException;


import org.springframework.jdbc.core.RowMapper;


import com.xdl.bean.BankAccount;


public class BankAccountMapper implements RowMapper {


@Override
public BankAccount mapRow(ResultSet rs, int arg1) throws SQLException {
return new BankAccount(rs.getString("ano"), rs.getString("aname"),
rs.getString("apassword"), rs.getDouble("money"));
}

}

实现方法：

package com.xdl.dao.imp;


import java.util.List;


import javax.annotation.Resource;


import org.springframework.dao.DataAccessException;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Repository;


import com.xdl.bean.BankAccount;
import com.xdl.dao.BankAccountDAO;
import com.xdl.mapper.BankAccountMapper;


@Repository("bankDao")
public class BankAccountDAOOracleImp implements BankAccountDAO {
    @Resource//注入模板  
    private  JdbcTemplate  jdbcTemplate;
@Override
public List listBankAccount() {
String  sql = "select * from bank_account";
return jdbcTemplate.query(sql, new BankAccountMapper());
}
@Override
public int deteleAccountByAno(String ano) {
String  sql = "delete from bank_account where ano = ?";
try {
return jdbcTemplate.update(sql, ano);
} catch (DataAccessException e) {
e.printStackTrace();
}
return  0;
}
@Override
public BankAccount getAccountByAno(String ano) {
String sql = "select * from bank_account where ano = ?";
List  accounts = jdbcTemplate.query(sql,
new BankAccountMapper(), ano);
return accounts.isEmpty()?null:accounts.get(0);
}
@Override
public int insertAccount(BankAccount account) {
String sql = "insert into bank_account values(?,?,?,?)";
try {
return jdbcTemplate.update(sql, account.getAno(),
account.getAname(),account.getApassword(),account.getMoney());
} catch (DataAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return  0;
}
@Override
public int updateAccount(BankAccount account) {
String sql = "update  bank_account set aname=?,apassword=?,"
+ "money=? where ano=?";
try {
return jdbcTemplate.update(sql, account.getAname(),account.getApassword()
,account.getMoney(),account.getAno());
} catch (DataAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return  0;
}

}

Service层

package com.xdl.service;


import java.util.List;


import javax.annotation.Resource;


import org.springframework.stereotype.Service;


import com.xdl.bean.BankAccount;
import com.xdl.dao.BankAccountDAO;


@Service
public class BankAccountService {
@Resource
     private   BankAccountDAO  bankDao;


public BankAccountDAO getBankDao() {
return bankDao;
}


public void setBankDao(BankAccountDAO bankDao) {
this.bankDao = bankDao;
}
/** 显示银行银行列表 */
public  List  listBankAccount(){
return  bankDao.listBankAccount();
}
/** 根据账号 删除账户  */
public  boolean  removeAccountByAno(String ano){
return  bankDao.deteleAccountByAno(ano)==1?true:false;
}
/** 根据账号 获取账户信息 */
public  BankAccount  accountInfoByAno(String ano){
return  bankDao.getAccountByAno(ano);
}
/** 开户方法 */
public  boolean   createAccount(BankAccount account){
return  bankDao.insertAccount(account)==1?true:false;
}
/** 更新方法 */
public  boolean   updateAccount(BankAccount account){
return  bankDao.updateAccount(account)==1?true:false;
