MyBatis-Flex 開發技能

MyBatis-Flex 是一個優雅的 MyBatis 增強框架，具有輕量、靈活、強大的特點。

@SpringBootApplication
@MapperScan("com.your.package.mapper")
public class Application {}

Entity 速查

@Table(value = "tb_account", dataSource = "ds2")
public class Account {
    @Id(keyType = KeyType.Auto)
    private Long id;
    @Column(value = "user_name")
    private String userName;
    @Column(isLogicDelete = true)
    private Boolean isDelete;
    @Column(version = true)
    private Integer version;
    @Column(tenantId = true)
    private Long tenantId;
    @ColumnMask(Masks.MOBILE_PHONE)
    private String phone;
}

詳見 entity-annotations.md

QueryWrapper 查詢

import static com.your.package.entity.table.AccountTableDef.ACCOUNT;

QueryWrapper query = QueryWrapper.create()
    .select(ACCOUNT.ID, ACCOUNT.USER_NAME)
    .from(ACCOUNT)
    .where(ACCOUNT.AGE.ge(18))
    .and(ACCOUNT.USER_NAME.like("張"))
    .orderBy(ACCOUNT.ID.desc());

// 動態條件
query.where(ACCOUNT.AGE.ge(18).when(age != null))
    .and(ACCOUNT.USER_NAME.like(name, If::hasText));

詳見 querywrapper-advanced.md

BaseMapper CRUD

public interface AccountMapper extends BaseMapper<Account> {}

accountMapper.insert(account);
accountMapper.selectOneById(1L);
accountMapper.selectListByQuery(query);
accountMapper.paginate(1, 10, query);
accountMapper.deleteById(1L);

// 部分欄位更新
Account entity = UpdateEntity.of(Account.class, 100L);
entity.setAge(20);
accountMapper.update(entity);

詳見 db-row-and-basemapper.md

關聯查詢

@RelationOneToOne(selfField = "id", targetField = "accountId")
private IDCard idCard;

@RelationOneToMany(selfField = "id", targetField = "accountId")
private List<Book> books;

@RelationManyToMany(joinTable = "tb_role_mapping",
    joinSelfColumn = "account_id", joinTargetColumn = "role_id")
private List<Role> roles;

詳見 relations-query.md

Service 層

public interface IAccountService extends IService<Account> {}

@Component
public class AccountServiceImpl extends ServiceImpl<AccountMapper, Account>
        implements IAccountService {}

accountService.save(account);
accountService.removeById(1L);
accountService.list(ACCOUNT.AGE.ge(18));
accountService.page(new Page<>(1, 10), query);

詳見 service-layer.md

高階特性

詳見 advanced-features.md

最佳實踐

推薦: Lambda語法、APT表定義類、分頁傳totalRow、when()動態條件

避免: setRaw()字串拼接（SQL隱碼攻擊）、Java專案引入Kotlin模組

這個技能包質量不錯，文件結構清晰、覆蓋全面，從基礎用法到高階特性都有詳細說明，程式碼示例豐富實用。對於想深入學習 MyBatis-Flex 框架的開發者來說是一份較為完整的參考資料。優點是內容詳盡、分類清晰；可改進的地方是缺少常見問題解答和最佳實踐案例。
