Modifying the EmployeeController.java File
Modify EmployeeController.java to replace the instance of the EmployeeDao.java class
with the instance of the IEmployeeDao.java interface.
To modify the EmployeeController.java file, complete the following steps:
1. Change an import statement to import the IEmployeeDao.java interface instead of
EmployeeDao.java
.
import com.hp.empinfo.service.IEmployeeDao;
2. Replace the EmployeeDao instance with that of IEmployeeDao as:
private IEmployeeDao empdao;
empdao = (IEmployeeDao) wac.getBean("iempdao");
After modification, the EmployeeController.java file must appear as:
package com.hp.empinfo.web;
import java.sql.SQLException;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.ServletException;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import com.hp.empinfo.domain.Employee;
import com.hp.empinfo.service.IEmployeeDao;
public class EmployeeController extends SimpleFormController {
private IEmployeeDao empdao;
public ModelAndView onSubmit(Object command) throws ServletException,
SQLException {
WebApplicationContext wac = WebApplicationContextUtils
.getRequiredWebApplicationContext(getServletContext());
empdao = (IEmployeeDao) wac.getBean("iempdao");
int empid = ((Employee) command).getEmpid();
String firstname = ((Employee) command).getFirstname();
String lastname = ((Employee) command).getLastname();
int age = ((Employee) command).getAge();
String email = ((Employee) command).getEmail();
String rord = ((Employee) command).getRord();
if (rord != null && rord.equalsIgnoreCase("Retrieve")) {
Employee emp1 = empdao.getDetail(empid);
Map<String, String> model = new HashMap<String, String>();
model.put("empid", "" + emp1.getEmpid());
model.put("empfn", emp1.getFirstname());
model.put("empln", emp1.getLastname());
model.put("empage", "" + emp1.getAge());
model.put("empemail", emp1.getEmail());
return new ModelAndView("retrieveresult", "model", model);
}
