测试SSM
jsp
从请求发起的地方开始
<body>
<h1>helloh1>
<a href="account/findAll">findAlla>
<a href="account/save">savea>
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" %>

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
2，配置Tomcat
点击ok即完成Tomcat配置
启动测试
运行Tomcat服务器
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。
