Hy guys,
i found somethin strange with StrutsTypeConverter.
let say i have a converter like this:
//------------------ begin DateConverter class ---------------
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Map;
import javax.annotation.PostConstruct;
import org.apache.commons.lang.ArrayUtils;
import org.apache.commons.lang.StringUtils;
import org.apache.struts2.util.StrutsTypeConverter;
public class DateConverter extends StrutsTypeConverter {
private String shortDateFormat;
@PostConstruct
public void loadFormat() {
this.shortDateFormat = "dd/MM/yyyy";
}
@SuppressWarnings("unused")
@Override
public Object convertFromString(Map arg0, String[] arg1, Class arg2) {
System.out.println("begin converter");
if(ArrayUtils.isEmpty(arg1) || StringUtils.isEmpty(arg1[0])) {
return null;
}
Date date = null;
try {
//cek kalo formatnya dd/MM/yyyy hh:mm:ss
if(arg1[0].contains(" ")) {
this.shortDateFormat = "dd/MM/yyyy hh:mm:ss";
date = new
SimpleDateFormat(shortDateFormat).parse(arg1[0]);
}else {
date = new
SimpleDateFormat(shortDateFormat).parse(arg1[0]);
}
}catch (ParseException e) {
System.out.println("DateConverter StrutsTypeConverter
gagal parsing date;");
e.printStackTrace();
}
System.out.println("end converter");
return date;
}
@Override
public String convertToString(Map arg0, Object arg1) {
System.out.println("begin converter to string");
if(arg1 instanceof Date) {
System.out.println("end converter to string");
return new
SimpleDateFormat(shortDateFormat).format((Date) arg1);
}
System.out.println("end converter to string");
return StringUtils.EMPTY;
}
}
//------------------ end DateConverter class ---------------
and in my action class, i have 2 property. one of them is Date type. and other
one is Pojo which one of that Pojo property have a Date type. so my action look
like this
//------------------ begin MasterPatienAction class ---------------
@Namespace("/patient")
@ParentPackage("app-default")
@Conversion(conversions = {
@TypeConversion(key = "birthDate", converterClass =
DateConverter.class)
})
public class MasterPatientAction extends BaseAction {
/**
*
*/
private static final long serialVersionUID = 1L;
private static transient Logger log =
Logger.getLogger(MasterPatientAction.class);
Patient patient;
List<Patient> listPatient;
Date birthDate;
@Action(value = "init", results = {
@Result(name = "success", location =
"/pages/pasient-main.jsp"),
@Result(name = "error", location =
"/pages/pasient-main.jsp"),
@Result(name = "input", location =
"/pages/pasient-main.jsp")
})
public String init() {
log.info("begin execute method init");
log.info("end execute method init");
return SUCCESS;
}
@Action(value = "search", results = {
@Result(name = "success", location =
"/pages/pasient-main.jsp"),
@Result(name = "error", location =
"/pages/pasient-main.jsp"),
@Result(name = "input", location =
"/pages/pasient-main.jsp")
})
public String search() {
log.info("begin execute method search");
if(birthDate!=null) {
patient.setPatientBirthDate(birthDate);
}
try {
listPasien = service.search(patient);
} catch (DnaException e) {
setMessageError("error caused : "+e.getMessage());
return ERROR;
}
log.info("end execute method search");
return SUCCESS;
}
//--setter getter
}
//------------------ end MasterPatienAction class ---------------
let say my pojo like this:
//------------------ begin Patient pojo class ---------------
public class Patient {
private integer patientId;
private String patientName;
private String patientCode;
private Date patientBirthDate;
//setter and getter goes here
}
//------------------ end Patient pojo class ---------------
for the first case, in my JSP, i use struts tag :
<s:textfield name="birthDate" class="form-control form-control-sm text-md
datepicker" placeholder="Birth Date dd/MM/yyyy"/>
until here, i dont have a problem with it. i can convert my date string (with
format dd/MM/yyyy e.g 20/01/2021) from JSP to the action class with this step:
1. request /patient/init (to show jsp)
2. insert value in text field with format dd/MM/yyyy e.g 20/01/2021
3. submit with action to /patient/search
4. in action class date converted successful on search method
5. return success from action class
6. text birthDate still the same (e.g 20/01/2021)
here the second case, when i want to convert my date type in my Pojo
so, i change my typeConversion key to : patient.patientBirthDate and also in my
textfield tag on JSP i change name to patient.patientBirthDate. so this is what
i change:
1. change key in TypeConvertion annotation to key = "patient.patientBirthDate"
2. change textfield tag in jsp to <s:textfield name="patient.patientBirthDate"
/>
when i follow step in first case:
1. request /patient/init (to show jsp)
2. insert value in text field with format dd/MM/yyyy e.g "20/01/2021"
3. submit with action to /patient/search
4. in action class date converted successfull
5. return success from action class
6. but my textfield with name patient.patientBirthDate in JSP change to
"1/20/21" (the value should not change. it should be "20/01/2021") also in my
console i dont see "begin converter to string" printed which i put in
convertToString method in converter class.
i use <struts-version>2.5.22</struts-version>
could someone explain to me and how can i fix it.
