@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
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文件映射 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);
}
}
