MiniDao1.9.0 版本发布,轻量级Java持久化框架

作者:互联网

项目介绍

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。

当前版本:v1.9.0 | 2022-09-02

MiniDao特征

An powerful enhanced toolkit of SpringJdbc for simplify development

具有以下特征:

代码体验

1. 接口定义[EmployeeDao.java]

@MiniDao
public interface EmployeeDao {

 @Arguments({ "employee"})
 @Sql("select * from employee")
 List<Map<String,Object>> 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<Employee> 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);
}
}
