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。

核心组件

• 
  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;
  

怎样使用

1. 
   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
   
   
2. 
   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;
   }
3. 
   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);
