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;
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
user
id
name
创建一个 Model:User, 她是这样的:
@Table(name = User.TABLE)
public class User extends DataRecordModel {
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 }
4.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 }
5.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 = "BruceZCQ"; //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 BruceZCQ 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);
