SSM整合

原始方式整合

啥都不做，浑然天成，相当于复习前面的内容。

创建数据库及对应表类

创建Maven工程

导入Maven坐标

编写实体类

package com.kiang.domain;

public class Account {
    private Integer id;
    private String name;
    private Double money;
    // 省略一系列get、set方法
}

编写Mapper接口

package com.kiang.mapper;

public interface AccountMapper {
    public void save(Account account);
    public List<Account> findAll();
}

编写Service接口及其实现

package com.kiang.service;

public interface AccountService {
    public void save(Account account);
    public List<Account> findAll();
}

package com.kiang.service.impl;

@Service("accountService")
public class AccountServiceImpl implements AccountService {
    @Override
    public void save(Account account) throws IOException {
        InputStream resourceAsStream = Resources.getResourceAsStream("sqlMapConfig.xml");
        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(resourceAsStream);
        SqlSession sqlSession = sqlSessionFactory.openSession();
        AccountMapper mapper = sqlSession.getMapper(AccountMapper.class);
        mapper.save(account);
        sqlSession.commit();
        sqlSession.close();
    }

    @Override
    public List<Account> findAll() throws IOException {
        InputStream resourceAsStream = Resources.getResourceAsStream("sqlMapConfig.xml");
        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(resourceAsStream);
        SqlSession sqlSession = sqlSessionFactory.openSession();
        AccountMapper mapper = sqlSession.getMapper(AccountMapper.class);
        List<Account> all = mapper.findAll();
        sqlSession.close();
        return all;
    }
}

编写Controller

package com.kiang.controller;

@Controller
@RequestMapping("/account")
public class AccountController {

    @Autowired
    private AccountService accountService;

    @RequestMapping(value = "/save", produces = "text/html;charset=UTF-8")
    @ResponseBody
    public String save(Account account) throws IOException {
        accountService.save(account);
        return "保存成功";
    }

    @RequestMapping("/findAll")
    public ModelAndView findAll() throws IOException {
        List<Account> accountList = accountService.findAll();
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.addObject("accountList", accountList);
        modelAndView.setViewName("accountList");
        return modelAndView;
    }
}

编写添加页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<h1>添加账户信息表单</h1>
<form name="accountForm" action="${pageContext.request.contextPath}/account/save" method="post">
    账户名称：<input type="text" name="name"><br>
    账户名称：<input type="text" name="money"><br>
    <input type="submit" value="保存"><br>
</form>
</body>
</html>

编写列表页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<h1>展示账户数据列表</h1>
<table border="1">
    <tr>
        <th>账户id</th>
        <th>账户名称</th>
        <th>账户金额</th>
    </tr>
    <c:forEach items="${accountList}" var="account">
        <tr>
            <td>${account.id}</td>
            <td>${account.name}</td>
            <td>${account.money}</td>
        </tr>
    </c:forEach>

</table>
</body>
</html>

编写相应配置文件

Spring整合MyBatis

整合思路

将Session工厂交给Spring容器管理，从容器中获得执行操作的Mapper实例即可。将事务交给Spring容器进行声明式事务控制。

修改spring配置文件

将SqlSessionFactory配置到Spring容器中
扫描Mapper，让Spring容器产生Mapper实现类
配置声明式事务控制
