一、搭建整合環境

SSM整合方式：XML + 註解的方式
環境爲idea的maven web原型工程

2. Web配置

而我們的web.xml中只配置了啓動時加載SpringMVC的配置文件導致Spring的配置文件的註解沒有被加載。爲了解決這個問題需要使用web服務器的監聽器來解決加載問題
使用監聽器原理：Web服務器中有一個全局ServletContext對象，每個Web發佈項目只有一個，隨着服務器啓動和關閉而創建和銷燬，因此我們可以創建一個監聽器(spring-web中的ContextLoaderListener類)監聽ServletContext對象的狀態，只要這個對象一創建，就開始加載Spring配置文件，這樣service中的類就會被掃描到。

二、測試案例

實體類：

@Data
public class Account {
    private int id;
    private String name;
    private double money;
}

控制層代碼

@Controller
public class AccountController {
    @Autowired
    AccountService service;

    @RequestMapping("/insert")
    public String account(Account account, Model model) {

        service.insertAccount(account);
        List<Account> list = service.findAll();
        model.addAttribute("accountList", list);
        return "ok";
    }
}

Dao層接口：

@Repository
public interface AccountDao {

    @Select("select * from tdte_db.spring_account")
    List<Account> findAll();

    @Insert("insert into tdte_db.spring_account(name,money) values (#{name},#{money})")
    int insertAccount(Account account);
}

業務層代碼

public interface AccountService {
    List<Account> findAll();
    int insertAccount(Account account);
}

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

    @Autowired
    private AccountDao dao;

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

    @Override
