10.Spring注解+MyBatis+Servlet

1.创建sql脚本

 create table account
 (
   id int(10) unsigned not null auto_increment primary key,
   account_number varchar(20) not null,
   account_pwd varchar(10) not null,
   account_money double(10,2) not null,
   account_status int(5) not null,
   create_time date not null
 );
 insert into account(account_number,account_pwd,
 account_money,account_status,create_time) values
 ('','',3000.00,1,'2015-05-06'),
 ('','',6000.00,1,'2015-05-07'),
 ('','',4000.00,1,'2015-05-08'),
 ('','',5000.00,1,'2015-05-09'),
 ('','',7000.00,2,'2015-05-10'),
 ('','',9000.00,2,'2015-05-11');
 commit;
 select * from account;

 insert into account
 (account_number,account_pwd,account_money,
 account_status,create_time)
 values(?,?,?,?,?)

account.sql

2.创建如下项目

3.导入jar文件

4.在src下的com.pojo包下创建Account.java

 package com.pojo;

 public class Account {
     private Integer id             ;
     private Integer account_status ;
     private Double account_money  ;
     private String account_number ;
     private String account_pwd    ;
     private String create_time    ;

     public Account() {
     }
     public Account(Integer accountStatus, Double accountMoney,
             String accountNumber, String accountPwd, String createTime) {
         account_status = accountStatus;
         account_money = accountMoney;
         account_number = accountNumber;
         account_pwd = accountPwd;
         create_time = createTime;
     }
     public Account(Integer id, Integer accountStatus, Double accountMoney,
             String accountNumber, String accountPwd, String createTime) {
         this.id = id;
         account_status = accountStatus;
         account_money = accountMoney;
         account_number = accountNumber;
         account_pwd = accountPwd;
         create_time = createTime;
     }
     public Integer getId() {
         return id;
     }
     public void setId(Integer id) {
         this.id = id;
     }
     public Integer getAccount_status() {
         return account_status;
     }
     public void setAccount_status(Integer accountStatus) {
         account_status = accountStatus;
     }
     public Double getAccount_money() {
         return account_money;
     }
     public void setAccount_money(Double accountMoney) {
         account_money = accountMoney;
     }
     public String getAccount_number() {
         return account_number;
     }
     public void setAccount_number(String accountNumber) {
         account_number = accountNumber;
     }
     public String getAccount_pwd() {
         return account_pwd;
     }
     public void setAccount_pwd(String accountPwd) {
         account_pwd = accountPwd;
     }
     public String getCreate_time() {
         return create_time;
     }
     public void setCreate_time(String createTime) {
         create_time = createTime;
     }
     @Override
     public String toString() {
         return "Account [account_money=" + account_money + ", account_number="
                 + account_number + ", account_pwd=" + account_pwd
                 + ", account_status=" + account_status + ", create_time="
                 + create_time + ", id=" + id + "]";
     }

 }

Account.java

5.在src下的com.mapper包下创建AccountMapper.java

 package com.mapper;

 import java.util.List;

 import com.pojo.Account;

 public interface AccountMapper {
     List<Account> findAll();

 }

AccountMapper.java

6.在src下的com.mapper包下创建AccountMapper.xml

 <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
 <mapper namespace="com.mapper.AccountMapper">

   <select id="findAll" resultType="com.pojo.Account">
      select * from  account
   </select>

 </mapper>

AccountMapper.xml

7.在src下的com.mapper包下创建AccountMapper.xml

8.在src下的com.mapper.impl包下创建AccountMapperImpl.java

 package com.mapper.impl;

 import java.util.List;

 import javax.annotation.Resource;

 import org.mybatis.spring.SqlSessionTemplate;
 import org.springframework.stereotype.Repository;

 import com.mapper.AccountMapper;
 import com.pojo.Account;

 /**
  *
  * AccountMapperImpl accountMapperImpl=new AccountMapperImpl()
  *
  */
 @Repository
 public class AccountMapperImpl implements AccountMapper {
     //定义spring给mybatis提供的sqlsession对象的
     @Resource
     private SqlSessionTemplate sqlSessionTemplate;

    /**
     * 查询所有
     */
     public List<Account> findAll() {
         AccountMapper mapper=sqlSessionTemplate.getMapper(AccountMapper.class);
         return mapper.findAll();
     }

 }

AccountMapperImpl.java

9.在src下的com.service包下创建AccountService.java

 package com.service;

 import java.util.List;

 import com.pojo.Account;

 public interface AccountService {
     List<Account> queryAccount();

 }

     @Resource
     private AccountMapper accountMapperImpl;

     public List<Account> queryAccount() {

         return accountMapperImpl.findAll();
     }

 }

 public class AccountServlet extends HttpServlet {

     public void doGet(HttpServletRequest request, HttpServletResponse response)
             throws ServletException, IOException {
        this.doPost(request, response);
     }

     public void doPost(HttpServletRequest request, HttpServletResponse response)
             throws ServletException, IOException {
         //1.乱码处理
         request.setCharacterEncoding("UTF-8");
         response.setCharacterEncoding("UTF-8");
         response.setContentType("text/html;charset=UTF-8");
         //2.接受参数
         String flag=request.getParameter("flag");

         AccountServiceImpl serivce=(AccountServiceImpl) ac.getBean("accountServiceImpl");

         if(flag==null){
             List<Account> list=serivce.queryAccount();
             request.setAttribute("list", list);
             request.getRequestDispatcher("index.jsp").forward(request, response);

         }else if(flag.equals("findbyid")){

         }else if(flag.equals("update")){

         }else if(flag.equals("add")){

         }else if(flag.equals("delete")){

         }
         //4.请求跳转
     }

 }

AccountServlet.java

12.在WebRoot下的web.xml下配置
