### MiniDao 简介及特征

An powerful enhanced toolkit of SpringJdbc for simplify development

MiniDao 是一款轻量级JAVA持久层框架,基于 SpringJdbc + freemarker 实现,具备Mybatis一样的SQL分离和逻辑标签能力。Minidao产生的初衷是为了解决Hibernate项目,在复杂SQL具备Mybatis一样的灵活能力,同时支持事务同步。

具有以下特征:

* O/R mapping不用设置xml,零配置便于维护
* 不需要了解JDBC的知识
* SQL语句和java代码的分离
* 只需接口定义,无需接口实现
* SQL支持脚本语言(强大脚本语言,freemarker语法)
* 支持与hibernate轻量级无缝集成
* 支持自动事务处理和手动事务处理
* 性能优于Mybatis
* 比Mybatis更简单易用
* SQL 支持注解方式
* SQL 支持独立文件方式,SQL文件的命名规则: 类名_方法名; SQL文件更容易定位,方便后期维护,项目越大此优势越明显
* SQL标签采用[Freemarker的基本语法](http://blog.csdn.net/zhangdaiscott/article/details/77505453)

代码体验
-----------------------------------
#### 1. 接口定义[EmployeeDao.java]
@MiniDao
public interface EmployeeDao {

@Arguments({ "employee"})
@Sql("select * from employee")
List> getAll(Employee employee);

@Sql("select * from employee where id = :id")
Employee get(@Param("id") String id);

@Sql("select * from employee where empno = :empno and name = :name")
Map getMap(@Param("empno")String empno,@Param("name")String name);

@Sql("SELECT count(*) FROM employee")
Integer getCount();

int update(@Param("employee") Employee employee);

void insert(@Param("employee") Employee employee);

@ResultType(Employee.class)
public MiniDaoPage getAll(@Param("employee") Employee employee,@Param("page") int page,@Param("rows") int rows);
}


#### 2. SQL文件[EmployeeDao_getAllEmployees.sql]
SELECT * FROM employee where 1=1
<#if employee.age ?exists>
and age = :employee.age
#if>
<#if employee.name ?exists>
and name = :employee.name
#if>
<#if employee.empno ?exists>
and empno = :employee.empno
#if>

#### 3. 接口和SQL文件对应目录

#### 4. 测试代码
public class Client {
public static void main(String args[]) {
BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext.xml");

EmployeeDao employeeDao = (EmployeeDao) factory.getBean("employeeDao");
Employee employee = new Employee();
String id = UUID.randomUUID().toString().replaceAll("-", "").toUpperCase();
employee.setId(id);
employee.setEmpno("A001");
employee.setSalary(new BigDecimal(5000));
employee.setBirthday(new Date());
employee.setName("scott");
employee.setAge(25);
//调用minidao方法插入
employeeDao.insert(employee);
}
}
