        4.4mybatis-数据连接配置：jdbc.properties

  2. jdbc.url=jdbc:mysql://localhost:3306/student?serverTimezone=GMT
  3. jdbc.username=root
  4. jdbc.password=root

  12.     <select id="findAll" resultType="Account">
  13.         select * from account
  14.     </select>
  15. </mapper>

          5.业务实现 ​​​​​​​

                5.1编写实体类
  1. public class Account {
  2.     private Integer id;
  3.     private String name;
  4.     private double money;
  5.  
  6.     public Integer getId() {
  7.         return id;
  8.     }
  9.     public void setId(Integer id) {
  10.         this.id = id;
  11.     }
  12.     public String getName() {
  13.         return name;
  14.     }
  15.     public void setName(String name) {
  16.         this.name = name;
  17.     }
  18.     public double getMoney() {
  19.         return money;
  20.     }
  21.     public void setMoney(double money) {
  22.         this.money = money;
  23.     }    
  24. }
                5.2编写Mapper接口
  1. public interface AccountMapper {
  2.     //1.插入账户Account
  3.     void save(Account account);
  4.     //2.查询所有的账户信息
  5.     List<Account> findAll();    
  6. }
                5.3编写Service接口
  1. public interface AccountService {
  2.     //1.调用mapper中的save方法
  3.    void save(Account account);//保存账户信息
  4.     //2.调用mapper中的findAll方法
  5.    List<Account> findAll();//查询账户数据
  6. }
                5.4编写Service接口的实现类
  1. public class AccountServiceImpl implements AccountService {
  2.     @Override
  3.     public void save(Account account) {
  4.         //调用AccountMapper接口的代理对象中的save方法
  5.         try {
  6.             InputStream resourceAsStream = Resources.getResourceAsStream("sqlMapConfig.xml");
  7.             SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(resourceAsStream);
  8.             SqlSession sqlSession = factory.openSession();
  9.             //AccountMapper代理对象
  10.             AccountMapper accountMapper = sqlSession.getMapper(AccountMapper.class);
  11.             accountMapper.save(account);
  12.             sqlSession.commit();
  13.             sqlSession.close();
  14.         } catch (IOException e) {
  15.             e.printStackTrace();
  16.         }
  17.     }
  18.     @Override
  19.     public List<Account> findAll() {
  20.         //调用AccountMapper接口的代理对象中的findAll方法
  21.         try {
  22.             InputStream resourceAsStream = Resources.getResourceAsStream("sqlMapConfig.xml");
  23.             SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(resourceAsStream);
  24.             SqlSession sqlSession = factory.openSession();
  25.             //AccountMapper代理对象
  26.             AccountMapper accountMapper = sqlSession.getMapper(AccountMapper.class);
  27.             List<Account> accountList = accountMapper.findAll();
  28.             sqlSession.close();
  29.             return accountList;
  30.         } catch (IOException e) {
  31.             e.printStackTrace();
  32.         }
  33.         return null;
  34.     }
  35. }

        6.controll层的业务方法实现

  1. @Controller
  2. public class AccountController {
  3.     @Autowired
  4.     private AccountService accountService;
  5.     
  6.     @RequestMapping("/save")
  7.     @ResponseBody
  8.     public String save(Account account){
  9.         //调用service层中AccountServiceImpl.save方法完成保存
  10.         accountService.save(account);
  11.         return "save success";
  12.     }
  13.     @RequestMapping("/findAll")
  14.     public ModelAndView findAll(){
  15.         ModelAndView model=new ModelAndView();
  16.         model.setViewName("accountList");// /pages/accountList.jsp
  17.         model.addObject("accountlist",accountService.findAll());
  18.         return model;
  19.     }
  20. }

        7.前端编写 ​​​​​​​

                7.1保存账户的页面 ​​​​​​​
  1. <%@ page contentType="text/html;charset=UTF-8" language="java" %>
  2. <html>
  3. <head>
  4.     <title>Title</title>
  5. </head>
  6. <body>
  7.   <h1>保存账户信息表单</h1>
  8.   <form action="${pageContext.request.contextPath}/save" method="post">
  9.       用户名称：<input type="text" name="name" ><br/>
  10.       用户金额：<input type="text" name="money"><br/>
  11.       <input type="submit" value="保存"><br/>
  12.   </form>
  13. </body>
  14. </html>
                7.2显示所有账户信息的页面 ​​​​​​​
  1. <%@ page contentType="text/html;charset=UTF-8" language="java" %>
  2. <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
  3. <html>
  4. <head>
  5.     <title>Title</title>
  6. </head>
  7. <body>
  8. <table border="1">
  9.     <tr>
  10.         <th>账户id</th>
  11.         <th>账户名称</th>
  12.         <th>账户金额</th>
  13.     </tr>
  14.     <c:forEach items="${accountlist}" var="account">
  15.         <tr>
  16.             <td>${account.id}</td>
  17.             <td>${account.name}</td>
  18.             <td>${account.money}</td>
  19.         </tr>
  20.     </c:forEach>
  21. </table>
  22. </body>
  23. </html>

        8.SSM框架整合的优化 ​​​​​​​

每次访问service层中的业务方法，就会创建SqlSessionFactory对象，出现了问题，如果经常访问service层中的业务方法，每次都需要重新创建SqlSessionFactory对象（需要来自sqlMapConfig.xml中的配置信息）

优化方案：启动web应用，创建SqlSessionFactory对象(数据库相关的配置信息移入applicationContext.xml文件中)，并存入spring容器中，service层中业务方法需要SqlSessionFactory对象，就从spring容器中获取即可

主要的工作是：sqlMapConfig.xml中的数据库配置信息移动到applicationContext.xml文件中

        8.1sqlMapConfig.xml配置信息移植到applicationContext.xml
