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
An powerful enhanced toolkit of SpringJdbc for simplify development
具有以下特征:
@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);
}
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>
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); } }
