Spring Batch - XML to MySQL

---

---

In this chapter, we will create a Spring Batch application which uses an XML Reader and a MySQL Writer.

Reader − The reader we are using in the application is StaxEventItemReader to read data from XML documents.

Create Project

Create a new maven project as discussed in Spring Batch - Environment Chapter.

Following is the input XML document we are using in this application. This document holds data records which specify details like tutorial id, tutorial author, tutorial title, submission date, tutorial icon, and tutorial description.

tutorials.xml

Create this file in src > main > resources folder of maven project.

         to develop effective Rich Internet Applications</tutorial_description>

Writer − The writer we are using in the application is JdbcBatchItemWriter to write the data to MySQL database. Assume we have created a table in MySQL inside a database called "details".

CREATE TABLE details.TUTORIALS( 
   tutorial_id int(10) NOT NULL, 
   tutorial_author VARCHAR(20), 
   tutorial_title VARCHAR(50), 
   submission_date VARCHAR(20), 
   tutorial_icon VARCHAR(200), 
   tutorial_description VARCHAR(1000) 
);

Processor − The processor we are using in the application is a custom processor which writes the data of each record on the PDF document.

In batch process, if "n" records or data elements were read, then for each record, it will read the data, process it, and write the data in the Writer. To process the data, it relays on the processor passed. In this case, in the custom processor class, we have written code to load a particular PDF document, create a new page, write the data item onto the PDF in a tabular format.

Finally, if you execute this application, it reads all the data items from the XML document, stores them in the MySQL database, and prints them in the given PDF document in individual pages.

jobConfig.xml

Following is the configuration file of our sample Spring Batch application. In this file, we will define the Job and the steps. In addition to these, we also define the beans for ItemReader, ItemProcessor, and ItemWriter. (Here, we associate them with their respective classes and pass the values for the required properties to configure them.)

App.java

Following is the code which launces the batch process. In this class, we will launch the Batch Application by running the JobLauncher.

Create this class in src > main > java folder of maven project.

      Job job = (Job) context.getBean("helloWorldJob");

      createPDFDocument();
	  
      // Executing the JOB 
      JobExecution execution = jobLauncher.run(job, new JobParameters()); 
      System.out.println("Exit Status : " + execution.getStatus());
