Spring Hot(1)Jersey Integration

Spring Hot(1)Jersey Integration

1. Marshal and UnMarshal the Object to XML
The object with annotation
package com.sillycat.easyspringrest.model;

import javax.xml.bind.annotation.XmlAccessType;

import javax.xml.bind.annotation.XmlAccessorType;

import javax.xml.bind.annotation.XmlElement;

import javax.xml.bind.annotation.XmlRootElement;

import javax.xml.bind.annotation.XmlTransient;

@XmlRootElement@XmlAccessorType(XmlAccessType.PUBLIC_MEMBER)

public class Product {

private Long id;

private String productName;

private String productLink;

private String desn;

//XmlTransient means that we will ignore in generated XML

@XmlTransient

public Long getId() {

 returnid;

}

publicvoid setId(Long id) {

 this.id = id;

}

@XmlElement(name="name")

public String getProductName() {

 return productName;

}

public void setProductName(String productName) {

 this.productName = productName;

}

public String getProductLink() {

 return productLink;

}

public void setProductLink(String productLink) {

 this.productLink = productLink;

}

public String getDesn() {

 return desn;

}

public void setDesn(String desn) {

 this.desn = desn;

}

@Override

public String toString() {

 return"Product [id=" + id + ", productName=" + productName + ", productLink=" + productLink + ", desn=" + desn + "]";

}

}

The main Application to Marshal and Unmarshal the Object
package com.sillycat.easyspringrest.model;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;

public class ProductJabxMain {

     public static void main(String[] args) {
          Product item1 = new Product();
          item1.setDesn("desn");
          item1.setId(Long.valueOf(1));
          item1.setProductLink("http://github.com/luohuazju");
          item1.setProductName("Product Name");

          try {
               File file = new File("/tmp/product.xml");
               JAXBContext jaxbContext = JAXBContext.newInstance(Product.class);
               Marshaller jaxbMarshaller = jaxbContext.createMarshaller();

               // output pretty printed
               jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

               jaxbMarshaller.marshal(item1, file);
          } catch (JAXBException e) {
               e.printStackTrace();
          }

          JAXBContext jaxbContext = null;
          Product item2 = null;
          FileReader fileReader = null;
          try {
               fileReader = new FileReader("/tmp/product.xml");

               jaxbContext = JAXBContext.newInstance(Product.class);
               item2 = (Product) jaxbContext.createUnmarshaller().unmarshal(
                         fileReader);
               System.out.println("Item:" + item2);
          } catch (JAXBException e) {
               e.printStackTrace();
          } catch (FileNotFoundException e) {
               e.printStackTrace();
          }
     }

}

2. Marshal and Unmarshal via Jackson
Dependency
<dependencyorg="org/codehaus/jackson"name="jackson-core-lgpl"rev="1.9.10"/><dependencyorg="org/codehaus/jackson"name="jackson-mapper-lgpl"rev="1.9.10"/>

Some new annotation
//XmlTransient means that we will ignore in generated XML@XmlTransient@JsonIgnore

@XmlElement(name="name")

@JsonProperty("name")

public String getProductName() {

 return productName;

}

The Main Application to Test the Annotation
package com.sillycat.easyspringrest.model;

import java.io.File;

import java.io.IOException;

import java.nio.file.Files;

import java.nio.file.Paths;

import org.codehaus.jackson.JsonGenerationException;

import org.codehaus.jackson.map.JsonMappingException;

import org.codehaus.jackson.map.ObjectMapper;

import org.codehaus.jackson.map.SerializationConfig;

public class ProductJSONMain {

public static void main(String[] args) throws JsonGenerationException, JsonMappingException, IOException {       

//create ObjectMapper instance       

ObjectMapper objectMapper = new ObjectMapper();        objectMapper.enable(SerializationConfig.Feature.INDENT_OUTPUT);       

//convert Object to json string       

Product item1 = new Product();       

item1.setDesn("desn");

item1.setId(Long.valueOf(1));

item1.setProductLink("http://github.com/luohuazju");

item1.setProductName("Product Name"); //write to file

File file = new File("/tmp/product.json");       

objectMapper.writeValue(file, item1); //read json file data to String       

byte[] jsonData = Files.readAllBytes(Paths.get("/tmp/product.json"));       

//convert json string to object       

Product item = objectMapper.readValue(jsonData, Product.class);                 System.out.println("Product Object\n" + item);

}

}
