测试SSM

手把手-快速搭建 SSM 项目框架----整合 SSM 基础配置

jsp

从请求发起的地方开始

<body>
    <h1>hello</h1>
    <a href="account/findAll">findAll</a>
    <a href="account/save">save</a>
</body>
  • findAll请求可以到达如下页面，展示所有数据
  • save请求测试事务的有效性，配置上面直接给出，不在说明
<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    <h1>success</h1>
    <table>
        <tr><td>id</td><td>name</td><td>money</td></tr>
        <c:forEach items="${accounts}" var="account">
            <tr>
                <td>${account.id}</td><td>${account.name}</td><td>${account.money}</td>
            </tr>
        </c:forEach>
    </table>
</body>
</html>

domain

public class Account implements Serializable{

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

Dao

@Repository
public interface IAccountDao {

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

    @Insert("insert into account values(#{id},#{name},#{money})")
    void saveAccount(Account account);
}

Service

IAccountService

public interface IAccountService {

    List<Account> findAll();
    void saveAccount(Account account);
}

AccountService

  • 其中saveAccount用@Transactional修饰，是为了测试事务，用int a=1/0;隔开，保证其原子性。
@Service
public class AccountService implements IAccountService {

    @Autowired
    IAccountDao accountDao;

    @Override
    public List<Account> findAll() {
        List<Account> accounts=accountDao.findAll();
        return accounts;
    }
    @Transactional
    @Override
    public void saveAccount(Account account) {
        accountDao.saveAccount(account);
        int a=1/0;
        Account account2=new Account();
        account2.setId(888);
        account2.setName("888");
        account2.setMoney(888.8);
        accountDao.saveAccount(account2);
    }
}

controller

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

    @Autowired
    AccountService accountService;
    /**
     * 查询所有账户
     * @return
     */
    @RequestMapping("findAll")
    public ModelAndView findAll(){
        ModelAndView mv =new ModelAndView();
        List<Account> accounts= accountService.findAll();
        mv.addObject("accounts",accounts);
        mv.setViewName("success");
        return mv;
    }
    /**
     * 保存新账户
     * @return
     */
    @RequestMapping("save")
    public String save(){
        Account account=new Account();
        account.setId(666);
        account.setName("myset");
        account.setMoney(123.3);
        accountService.saveAccount(account);
        return "hello";
    }

}

test

测试类配置

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations= {"classpath:applicationContext.xml"})
public class test {

    @Autowired
    AccountService accountService;

    @Test
    public void test(){
        //accountService.findAll();
    }
}

配置Tomcat启动

配置

1,添加Tomcat

点击findAll，成功查询到我数据库的内容

点击save，可以看到保存失败，可以看到事务相关的消息，说明事务回滚，两个账户都没有保存。
