Java Odata tutorial part 1

Hi 🙂 This tutorial will be written in English. I hope this will not a problem for you.

Let’s get started. First of all you should create empty project with your model. I make all operations in IntellIJ, repository is available on github under this url: https://github.com/pawelwiejkut/olingo_odata_tutorial

1. Open IntelIJ and create a package “model”.
2. Our class model should look like on image bellow:
3. Create three classes in the package: Parcel,  Address,  Warehouse.
4. Parcel class:
   
   Java

   package model; import java.util.HashSet; import java.util.Set; /** * Created by pawelwiejkut on 02.05.2017. */ public class Parcel { private Address senderAddress; private Address reciverAddress; private Set<Warehouse> warehouse; private String content; public Address getSenderAddress() { return senderAddress; } public void setSenderAddress(Address senderAddress) { this.senderAddress = senderAddress; } public Address getReciverAddress() { return reciverAddress; } public void setReciverAddress(Address reciverAddress) { this.reciverAddress = reciverAddress; } public String getContent() { return content; } public void setContent(String content) { this.content = content; } public Set getWarehouse() { if (warehouse == null) { warehouse = new HashSet(); } return warehouse; } public void addGoods(Warehouse warehouse) { getWarehouse().add(warehouse); } }

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51

   package model;   import java.util.HashSet; import java.util.Set;   /** * Created by pawelwiejkut on 02.05.2017. */ public class Parcel {       private Address senderAddress;     private Address reciverAddress;     private Set<Warehouse> warehouse;     private String  content;       public Address getSenderAddress() {         return senderAddress;     }       public void setSenderAddress(Address senderAddress) {         this.senderAddress = senderAddress;     }       public Address getReciverAddress() {         return reciverAddress;     }       public void setReciverAddress(Address reciverAddress) {         this.reciverAddress = reciverAddress;     }       public String getContent() {         return content;     }       public void setContent(String content) {         this.content = content;     }       public Set getWarehouse() {         if (warehouse == null) {             warehouse = new HashSet();         }         return warehouse;     }       public void addGoods(Warehouse warehouse) {         getWarehouse().add(warehouse);     }   }

5. Address class:
   
   Java

   package model; /** * Created by pawelwiejkut on 02.05.2017. */ public class Address { private String street; private String buildingNumber; private String apartmentNumber; private String postCode; public String getStreet() { return street; } public void setStreet(String street) { this.street = street; } public String getBuildingNumber() { return buildingNumber; } public void setBuildingNumber(String buildingNumber) { this.buildingNumber = buildingNumber; } public String getApartmentNumber() { return apartmentNumber; } public void setApartmentNumber(String apartmentNumber) { this.apartmentNumber = apartmentNumber; } public String getPostCode() { return postCode; } public void setPostCode(String postCode) { this.postCode = postCode; } }

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44

   package model;   /** * Created by pawelwiejkut on 02.05.2017. */ public class Address {       private String street;     private String buildingNumber;     private String apartmentNumber;     private String postCode;       public String getStreet() {         return street;     }       public void setStreet(String street) {         this.street = street;     }       public String getBuildingNumber() {         return buildingNumber;     }       public void setBuildingNumber(String buildingNumber) {         this.buildingNumber = buildingNumber;     }       public String getApartmentNumber() {         return apartmentNumber;     }       public void setApartmentNumber(String apartmentNumber) {         this.apartmentNumber = apartmentNumber;     }       public String getPostCode() {         return postCode;     }       public void setPostCode(String postCode) {         this.postCode = postCode;     } }

6. Warehouse class:
   
   Java

   package model; /** * Created by pawelwiejkut on 02.05.2017. */ public class Warehouse { private Address address; private String warehouseName; public Address getAddress() { return address; } public void setAddress(Address address) { this.address = address; } public String getWarehouseName() { return warehouseName; } public void setWarehouseName(String warehouseName) { this.warehouseName = warehouseName; } }

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

   package model;   /** * Created by pawelwiejkut on 02.05.2017. */ public class Warehouse {       private Address address;     private String  warehouseName;       public Address getAddress() {         return address;     }       public void setAddress(Address address) {         this.address = address;     }       public String getWarehouseName() {         return warehouseName;     }       public void setWarehouseName(String warehouseName) {         this.warehouseName = warehouseName;     } }

   It’s all in this part. Next time we try to set up maven project. See you soon ! 🙂
