猿创征文|Spring、SpringMVC、Mybatis整合测试

SSM整合测试

①创建数据库

②创建maven工程

③pom.xml中导入对应的坐标

  <dependencies>
    <!--spring相关-->
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context</artifactId>
      <version>5.0.5.RELEASE</version>

      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>5.0.5.RELEASE</version>
    </dependency>

    <!--servlet和jsp-->
    <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>servlet-api</artifactId>
      <version>2.5</version>
    </dependency>
    <dependency>
      <groupId>javax.servlet.jsp</groupId>
      <artifactId>jsp-api</artifactId>
      <version>2.0</version>
    </dependency>

    <!--mybatis相关-->
    <dependency>
      <groupId>org.mybatis</groupId>
      <artifactId>mybatis</artifactId>
      <version>3.4.5</version>
    </dependency>
    <dependency>
      <groupId>org.mybatis</groupId>
      <artifactId>mybatis-spring</artifactId>

    </dependency>
    <dependency>

      <version>5.1.6</version>
    </dependency>
    <dependency>
      <groupId>c3p0</groupId>
      <artifactId>c3p0</artifactId>
      <version>0.9.1.2</version>

      <groupId>jstl</groupId>
      <artifactId>jstl</artifactId>
      <version>1.2</version>
    </dependency>

  </dependencies>

④编写实体类

public class Account {

    private Integer id;
    private String name;
    private Double money;

//get set方法
}

⑤编写Mapper接口（dao接口）


public interface AccountMapper {
   @Insert(" insert into account values(#{id},#{name},#{money})")
    public void save(Account account);

@Select(" select * from account")
    public List<Account> findAll();

}

⑥编写service接口


public interface AccountService {

    public void save(Account account);

    public List<Account> findAll();

}

⑦编写Service接口实现


@Service("accountService")
public class AccountServiceImpl implements AccountService {

    @Autowired
    private AccountMapper accountMapper;

    @Override
    public void save(Account account) {
        accountMapper.save(account);
    }

    @Override
    public List<Account> findAll() {
        return accountMapper.findAll();
    }
}

⑧编写Controller


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

    @Autowired
    private AccountService accountService;

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

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

}

⑨编写jsp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>
        账户金额:<input type="text" name="money"><br>
        <input type="submit" value="保存"><br>
    </form>
</body>
</html>

⑩编写列表jsp展示页面

<%@ 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>

①①编写响应的配置文件
