Step 3: Now we need to create company.xml file under project- create one xml file add the below xml to that file.

Step 4: Create pojo classes , which need to be parsed as per above xml.
i have created 3 classes - Company.java -> List of Employee.java -> List Of Address.java
Company.java - xmlroot elment is company which is there in xml.
package xmltofile;
import java.util.ArrayList;
import java.util.List;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement(name="company")
public class Company {
private List employee = new ArrayList();
@XmlElement(name="employee")
public List getEmployee() {
return employee;
}
public void setEmployee(List employee) {
this.employee = employee;
}
}
Employee.java
package xmltofile;
import java.util.ArrayList;
import java.util.List;
import javax.xml.bind.annotation.XmlElement;
public class Employee {
private String name;
private int age;
private String gender;
private Double salary;
private String dob;
Listaddress = new ArrayList();
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public Double getSalary() {
return salary;
}
public void setSalary(Double salary) {
this.salary = salary;
}
@XmlElement
public ListgetAddress() {
return address;
}
public void setAddress(Listaddress) {
this.address = address;
}
public String getDob() {
return dob;
}
public void setDob(String dob) {
this.dob = dob;
}
}
Address.java
package xmltofile;
import javax.xml.bind.annotation.XmlRootElement;
public class Address {
private String city;
private String type;
private String state;
private String country;
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getState() {
return state;
}
public void setState(String state) {
this.state = state;
}
public String getCountry() {
return country;
}
public void setCountry(String country) {
this.country = country;
}
}
Step 6: Now we need to write test class to Parse the employee.xml using JAXB context and create the Flat file
and write the xml data into file at specified index.
XMLReaderAndWriteToFile.java
package xmltofile;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.Unmarshaller;
import com.ancientprogramming.fixedformat4j.format.FixedFormatManager;
import com.ancientprogramming.fixedformat4j.format.impl.FixedFormatManagerImpl;
import xmltofile.fixedformat.CompanyHeader;
import xmltofile.fixedformat.EmployeeHeader;
public class XMLReaderAndWriteToFile {
public static void main(String[] args) {
BufferedWriter bw = null;
try {
JAXBContext context = JAXBContext.newInstance(Company.class);
// Create Unmarshaller using JAXB context
Unmarshaller unmarshaller = context.createUnmarshaller();
System.out.println("xml file started to load...");
Company company = (Company) unmarshaller.unmarshal(new File("employee.xml"));
System.out.println("xml file loaded and parsed successfully..");
// Write to file with fixedformat
System.out.println("Flat file started to create...");
bw = new BufferedWriter(new FileWriter("fixedLength.txt", true));
System.out.println("empty flat file created...");
getCompanyHeader(bw);
System.out.println("company header written successfully to file.");
getEmployeeHeader(bw);
System.out.println("employee header written successfully to file.");
for (Employee employee : company.getEmployee()) {
EmployeeHeader employeeDetails = new EmployeeHeader();
employeeDetails.setNameHeader(employee.getName());
employeeDetails.setAgeHeader(String.valueOf(employee.getAge()));
employeeDetails.setGenderHeader(employee.getGender());
employeeDetails.setDobHeader(String.valueOf(employee.getDob()));
employeeDetails.setSalaryHeader(String.valueOf(employee.getSalary()));
String completeAddress = " ";
for (Address address : employee.getAddress()) {
String addressDetails = address.getCity() + " " + address.getState() + " " + address.getCountry()
+ " - " + address.getType();
completeAddress = completeAddress.concat(addressDetails) + " ";
}
employeeDetails.setAddressHeader(completeAddress);
FixedFormatManager manager1 = new FixedFormatManagerImpl();
String data1 = manager1.export(employeeDetails);
bw.write(data1);
bw.newLine();
}
System.out.println("Employee details written successfully to file.");
} catch (Exception ex) {
ex.printStackTrace();
} finally {
try {
bw.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
private static void getEmployeeHeader(BufferedWriter bw) throws IOException {
EmployeeHeader employeeHeader = new EmployeeHeader();
employeeHeader.setNameHeader("Employee Name");
employeeHeader.setAgeHeader("Age");
employeeHeader.setGenderHeader("Gender");
employeeHeader.setDobHeader("DOB");
employeeHeader.setSalaryHeader("Salary");
employeeHeader.setAddressHeader("Address");
FixedFormatManager manager = new FixedFormatManagerImpl();
String data = manager.export(employeeHeader);
bw.write(data);
bw.newLine();
bw.newLine();
bw.newLine();
}
private static void getCompanyHeader(BufferedWriter bw) throws IOException {
CompanyHeader companyHeader = new CompanyHeader();
companyHeader.setHeader1("ABC Company");
companyHeader.setHeader2("Bangalore");
companyHeader.setHeader3("India");
FixedFormatManager manager = new FixedFormatManagerImpl();
String data = manager.export(companyHeader);
bw.write(data);
bw.newLine();
bw.newLine();
bw.newLine();
}
}
Output file will be like this.
ABC Company Bangalore
Employee Name Age Gender Salary DOB Address
siva 34 Male 35000.0 01/07/1983 Bangalore Karnataka India - Present Kadapa AndharaPradesh India - Permanent

This Post will explain , how to Deploy Spring Boot Application on Pivotal Cloud Foundry Platform
Now a days Cloud Computing and Microservice have become very popular concept and almost all the organizations are investing and adapting it very fast. Currently there are only
few popular cloud providers in the market and Pivotal Cloud Foundry is one of them. It is a PaaS(Platform AS A Servcie) service where we can easily deploy and manage our
applications and the Cloud Foundry will take care of the rest of the cloud based offerings like scalability, high availability etc.
Today we will learn to deploy spring boot application in Pivotal cloud foundry platform called as Pivotal Web Services.
Step 1: What is Cloud Foundry?
Cloud Foundry is an open-source platform as a service (PaaS) that provides you with a choice of clouds, developer frameworks, and application services. It is open source and it is governed by the Cloud Foundry Foundation. The original Cloud Foundry was developed by VMware and currently it is managed by Pivotal
Step 2: Now we need to install Cloud Foundary on Windows
Step 8: Provide necessary details and sign up the same.
Once sign up is completed, we can log into the Pivotal webservice console through the login screen of the pivotal web service console.
After providing login credentials successfully we will get into the cloud foundry console where we can see all the deployed applications, can monitor the applications and do many more activities. Here we need to add org and space etc...
Step 9: Once we have created org and space successfully.. now we need to deploy the spring boot application in PCF.
Step 10: Before that , Login in to PWS (Pivotal Webservice Console) using CLI
c:/> cf login -a api.run.pivotal.io
Provide username and password which is given , while registering the PWS.
same way we can use Logout
c:/> cf logout
Step 11: Now login and logout is working with out any issues.
Step 12: Now write simple spring boot application and run the same in locally.
If you want to write simple one follow the https://start.spring.io/ - which will create sample spring boot application for you and modify as per your requirment.
i have created one sample arthimetic operations spring boot application.. check in my previous post for the same.
add the below code into bootstrap.properties under src\main\resources
Step 19: This is how we will implement spring boot application and we can deploy the same in Pivotal Cloud Foundary.
