JFinal-DbHelper
继承了 JFinal 的牛逼，速度，简化的 JFinal 数据库操作，透明操作 Redis，让你全心安心做你的业务，数据缓存，统统把你解决掉。
- DbHelperKit: 封装了 JFinal DbKit，直接使用 Map 来装数据库的每一行数据;
- DbHelperTx: 简化了 Tx 操作;
- DataRecordModel: 数据库表的工具 Model, 继承这个 Model,加上和数据库字段一样的属性,你的牛逼 Db 操作之路就开始了;
- DBService: 提供了常见的 CRUD, 可以简单的 CRUD 同时把数据也“偷偷”的写到了 Redis 哦;
- 假设你的表是这样的:
CREATE TABLE `user` (
`id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `id` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4- 创建一个 Model:User, 她是这样的:
@Table(name = User.TABLE)
public class User extends DataRecordModel<User> {
private static final long serialVersionUID = 7098160284590588258L;
public static final String TABLE = "user";
public static final String TABLE_AS = "u";
// SQL Fields
public static final String ID = "id";
public static final String NAME = "name";
//SQL Field As
public static final String ID_AS = "id";
public static final String NAME_AS = "name";
@Table.PrimaryKey
@Table.Column(name = User.ID, as = User.ID_AS, originType = Table.ColumnOriginType.BIGINT)
public String id;
@Table.Column(name = User.NAME, as = User.NAME_AS, originType = Table.ColumnOriginType.STRING)
public String name;
}- 接下来你再创建一个 Service,她是这样的:
public class UserService extends DBService {
private static final long serialVersionUID = -6341896364271284419L;
//这里放自定义的其他方法
}- 在加上一个 RedisCacheService, 她是这样的:
public class UserRedisService extends RedisCacheService {
private static final long serialVersionUID = 8673372135373269417L;
//这里放自定义的其他方法
}- 完成了上面的工作, 你就可以开始使用了哦:
//设置产品 name
ProductKit.PRODUCT_NAME = "zcq";
User user = new User();
user.name = "Jobsz";
//save
UserService userService = new UserService();
boolean ret = userService.save(user);
System.out.println("save =="+ret);
//find id = 6
user.id = "6";
Map<String, Object> find = userService.findOne(user);
System.out.println("find =="+find);
//find to User
User otherUser = user.parser(find);
System.out.println("other user == "+otherUser);
//findall
Object all = userService.findAll(user);
System.out.println("findall =="+all);
//update Jobsz to newName
user.name = "newName";
ret = userService.update(user);
System.out.println("update =="+ret);
//delete id = 10
user.id = "10";
ret = userService.delete(user);
System.out.println("delete=="+ret);- 最后是怎样的？
