java – 使用spring jdbc模板填充结果

我有两节课

class Deptartment{
  int deptid,String deptname;
  List

现在我如何使用spring jdbc模板填充Department对象？

最佳答案

为了帮助Sean Patrick Floyd,这是他的解决方案,只需一个查询：

final MapsqlException {
            Integer deptId = rs.getInt("deptid");
            Department d = (Department) departments.get(deptId);
            if (d == null) {
                String deptName = rs.getString("deptname");
                d = new Department();
                d.setDeptId(deptId);
                d.setDeptName(deptName);
                departments.put(deptId,d);
            }
            Employee employee = new Employee();
            employee.setEmpId(rs.getInt("empid"));
            employee.setEmpName(rs.getString("empname"));
            employee.setDeptId(deptId);
            d.getEmployees().add(employee);
            return employee;
        }
    });
List

它恰好更短,更有效.
