Tutorial Form Tags Apache Struts2

Kita lanjutkan belajar struts2 dengan judul Tutorial Form Tags Apache Struts2. Kita akan sedikit mengulas bagaimana membuat form menggunakan library tags yang dimiliki struts2.

Sekarang kita mulai Tutorial Form Tags Apache Struts2 :

Buka folder workspace anda, jangan lupa pelajari dulu Tutorial Basic Apache Struts2. Karena kita akan melanjutkan source codenya.
Buat folder “form-tags-struts2” di workspace anda
Copy file “pom.xml” dan folder “src” di folder “basic-struts2” tutorial sebelumnya ke folder “form-tags-struts2”

Buka file “pom.xml”, rubah artifact-id, name, dan description

<artifactId>form-tags-struts2</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>war</packaging>
<name>Belajar Form Tags Struts2</name>
<description>Belajar Form Tags Struts2</description>

<artifactId>form-tags-struts2</artifactId>

<version>0.0.1-SNAPSHOT</version>

<name>Belajar Form Tags Struts2</name>

<description>Belajar Form Tags Struts2</description>

Buka IDE eclipse
Pilih import >> existing maven project >> browse ke folder “form-tags-struts2” >> finish
project baru “form-tags-struts2” sudah berhasil di load

Mari kita mulai melakukan perubahan selanjutnya

Tambahkan class sebagai objek model dengan nama “Person” di package “com.wijaksana.belajar.struts2.model”, dengan attribut/properti:

private String firstName;
private String lastName;
private String sport;
private String gender;
private String residency;
private boolean over21;
private String [] carModels;

private String firstName;

private String lastName;

private String sport;

private String gender;

private String residency;

private boolean over21;

private String [] carModels;

Aktfikan getter setter untuk atribut/properti diatas

Tambahkan/overide method toString, seperti dibawah ini:

public String toString()
{
	return "First Name: " + getFirstName() + " | " +
	" Last Name:  " + getLastName() + " | " +
	" Favorite Sport: " + getSport() + " | " +
	" Gender: " + getGender() + " | " +  
	" Residency: " + getResidency() + " | " +
	" Over 21: " + isOver21()  + " | " +
	" Car models: " + Arrays.asList( getCarModels() ) ;
	
}

public String toString()

{

return "First Name: " + getFirstName() + " | " +

" Last Name: " + getLastName() + " | " +

" Favorite Sport: " + getSport() + " | " +

" Gender: " + getGender() + " | " +

" Residency: " + getResidency() + " | " +

" Over 21: " + isOver21() + " | " +

" Car models: " + Arrays.asList( getCarModels() ) ;

}

Tambahkan class sebagai objek model dengan nama “State” di package “com.wijaksana.belajar.struts2.model”, dengan attribut/properti:

Java

private String stateAbbr; private String stateName;

1
2

private String stateAbbr;
private String stateName;
Aktfikan getter setter untuk atribut/properti diatas
Tambahkan Constructor dengan parameter 2 attribut/properti, seperti dibawah ini:

Java

public State (String stateAbbr, String stateName) { this.stateAbbr = stateAbbr; this.stateName = stateName; }

1
2
3
4

public State (String stateAbbr, String stateName) {
this.stateAbbr = stateAbbr;
this.stateName = stateName;
}
Tambahkan interface sebagai kerangka service untuk akses data ke database dengan nama “EditService” di package “com.wijaksana.belajar.struts2.service”, seperti script dibawah ini:

Java

public interface EditService { Person getPerson() ; void savePerson(Person personBean); }

1
2
3
4

public interface EditService {
Person getPerson() ;
void savePerson(Person personBean);
}

Tambahkan class implementasi dari interface service dengan nama “EditServiceImpl” di package “com.wijaksana.belajar.struts2.service” jangan lupa ya implements ke “EditService”, sementara kita akan menyimpan datanya dalam memori. Berikut scriptnya:

public class EditServiceImpl implements EditService {	
	
	private static Person person ;
	private static String [] carModels = {"Ford","Nissan"};
	
	static {		
		person = new Person();
		person.setFirstName("Bruce");
		person.setLastName("Phillips");
		person.setSport("Basketball");
		person.setGender("Male");
		person.setResidency("AD");
		person.setOver21(true);		
		person.setCarModels( carModels);		
	}
	
	public Person getPerson() {		
		return EditServiceImpl.person;
	}

	public void savePerson(Person personBean) {
		EditServiceImpl.person.setFirstName(personBean.getFirstName() );
		EditServiceImpl.person.setLastName(personBean.getLastName() );
		EditServiceImpl.person.setSport(personBean.getSport() );
		EditServiceImpl.person.setGender( personBean.getGender() );
		EditServiceImpl.person.setResidency( personBean.getResidency() );
		EditServiceImpl.person.setOver21( personBean.isOver21() );
		EditServiceImpl.person.setCarModels(personBean.getCarModels() );
	}
}

public class EditServiceImpl implements EditService {

private static Person person ;

private static String [] carModels = {"Ford","Nissan"};

static {

person = new Person();

person.setFirstName("Bruce");

person.setLastName("Phillips");

person.setSport("Basketball");

person.setGender("Male");

person.setResidency("AD");

person.setOver21(true);

person.setCarModels( carModels);

}

public Person getPerson() {

return EditServiceImpl.person;

}

public void savePerson(Person personBean) {

EditServiceImpl.person.setFirstName(personBean.getFirstName() );

EditServiceImpl.person.setLastName(personBean.getLastName() );

EditServiceImpl.person.setSport(personBean.getSport() );

EditServiceImpl.person.setGender( personBean.getGender() );

EditServiceImpl.person.setResidency( personBean.getResidency() );

EditServiceImpl.person.setOver21( personBean.isOver21() );

EditServiceImpl.person.setCarModels(personBean.getCarModels() );

}
