SSM(Spring+SpringMVC+MyBatis)简易整合
SSM简易整合
这里为了演示效果，就用Account 账号类演示
目录结构
数据库 ssm_demo，数据表 t_account

Account 账号实体类
public class Account implements Serializable {
private Integer id;
private String name;
private Double money;
//省略 getter、setter、toString方法
}
3层架构：dao、service、controller
dao 层：IAccountDao 接口（演示效果，所以只做了查询和保存操作）
@Repository
public interface IAccountDao {
//查询全部
@Select("select * from t_account")
public List<Account> findAll();
//保存
@Insert("insert into t_account(name,money) values(#{name},#{money})")
public void saveAccount(Account account);
}
service 层：IAccountService 接口
public interface IAccountService {
//查询全部
public List<Account> findAll();
//保存
public void saveAccount(Account account);
}
service 层的实现类：IAccountServiceImpl 类
@Service("accountService")
public class AccountServiceImpl implements IAccountService {
@Autowired
IAccountDao accountDao;
@Override
public List<Account> findAll() {
System.out.println("AccountServiceImpl：查询全部");
return accountDao.findAll();
}
@Override
public void saveAccount(Account account) {
System.out.println("AccountServiceImpl：保存账号");
accountDao.saveAccount(account);
}
}
controller 层：AccountController 类
@Controller
@RequestMapping("/account")
public class AccountController {
@Autowired
private IAccountService accountService;
@RequestMapping("/findAll")
public String findAll(Model model){
System.out.println("AccountController:findAll()");
List<Account> list = accountService.findAll();
model.addAttribute("list",list);
return "list";
}
@RequestMapping("/save")
public void save(Account account, HttpServletRequest request, HttpServletResponse response) throws Exception{
System.out.println("AccountController:save()");
accountService.saveAccount(account);
response.sendRedirect(request.getContextPath()+"/account/findAll");
}
}
目录结构中的SpringTest 类只是测试用途，不用理。
