Improving the Controller
Modify the EmployeeController.java file to perform the employee database transactions.
To modify the EmployeeController.java file, complete the following steps:
1.
Add a reference to the EmployeeDao.java in the EmployeeController.java controller
class as shown below:
private EmployeeDao empdao;
2. Replace the onSubmit method with the handleRequest method.
This is done to:
1. Recognize the inputs from the View
2. Pass the recognized inputs to the Model
3. Pass the output back to the View
Before modification:
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
String now = (new Date()).toString();
logger.info("Returning view with " + now);
return new ModelAndView("insert", "now", now);
}
After modification:
public ModelAndView onSubmit(Object command) throws ServletException,
SQLException {
WebApplicationContext wac = WebApplicationContextUtils
.getRequiredWebApplicationContext(getServletContext());
empdao = (EmployeeDao) wac.getBean("empdao");
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();
empdao.insertDetail(empid, firstname, lastname, age, email);
Map<String, String> model = new HashMap<String, String>();
