### 项目介绍
QuickDAO通过对Spring JDBC, MyBatis, sql2o等orm框架进行简单封装，实现增删改查方法的抽象和复用，有效消除DAO层的样板代码。
### 项目文档
[https://yangziwen.github.io/quick-dao](https://yangziwen.github.io/quick-dao/)
### 快速开始
* 引入项目依赖
```xml
io.github.yangziwen
quick-dao-spring-jdbc
0.0.21
io.github.yangziwen
quick-dao-mybatis
0.0.21
io.github.yangziwen
quick-dao-sql2o
0.0.21
```
* 定义数据的实体类
数据库的表名、字段名默认由实体类的类名、字段名按驼峰法转下划线法获得，也可基于JPA注解显式指定
```java
@Data
@Table(name = "user")
public class User {
@Id
@Column
@GeneratedValue
private Long id;
@Column
private String username;
@Column
private String email;
@Column
private Integer age;
}
```
* 数据访问类继承BaseRepository接口的实现类(以Spring JDBC为例)
```java
public class UserRepository extends BaseSpringJdbcRepository {
public UserRepository(DataSource dataSource) {
super(new JdbcTemplate(dataSource));
}
// UserRepository已继承了针对User对象的增删改查(包括分页)方法
}
```
* 在数据访问类中实现个性化的查询方法
```java
public List listByAgeRange(int minAge, int maxAge) {
Criteria criteria = new Criteria()
.and("age").ge(minAge)
.and("age").le(maxAge);
return list(criteria);
}
```
* 使用类型安全的方式构造查询条件
```java
public List listByAgeRange(int minAge, int maxAge) {
Criteria criteria = new TypedCriteria<>(User.class)
.and(User::getAge).ge(minAge)
.and(User::getAge).le(maxAge);
return list(criteria);
}
```
