Five most useful spring modules

 Java Spring framework is one of the popular java frameworks.

A thread on 5 commonly used spring modules

1. Spring Boot and Spring MVC
These modules makes it easy and quick to create stand-alone, production-grade Spring based Applications that you can "just run".
Example Use:- A RESTful service with self-container server.

2. Spring Batch
This module is used to build batch applications that need to recurrently process large volumes of data.
Features: Chunk based processing, retry, skip
Example Use:- Everyday, read data of daily trades from database and update the credit on customer's accounts.

3.Spring Data
Provides a spring based programming model for accessing data.
This module has very powerful features and supports wide range of databases.
Example Use:- Read, Write data from PostgreSQL for your application.

4.Spring Cloud
Provides tools for developers to quickly build some of the common patterns of distributed systems.
Libraries for Service registration and discovery, Circuit breaker, Load balancing etc. are available.
Example Use:- Ecommerce application built using microservices.

5. Spring Security
This is the de-facto standard for securing Spring-based applications.
Provides authorization and authentication for java applications.
Example Use:- A bank application that needs authentication and authorization for various user roles.

Most of the times you will use multiple spring libraries/modules together.
For detailed explanation of various modules, visit the official spring documentation 

Let me know in comments if you are looking for detailed explanation of any spring module.

How to convert a CSV file to XLSX

I wrote this utility for a friend of mine who wanted to convert large (~50MB) CSV files to XLSX. The CSV files had comma "," as a delimiter. I have used apache poi utility in this program. https://www.apache.org/dyn/closer.lua/poi/release/RELEASE-NOTES.txt This code uses SXSSFWorkbook class. The SXSSFWorkbook class uses "BigGridDemo" strategy, where only portions being processed are kept in memory. There are temporary files created which store the rest of the temporary data. setCompressTempFiles() method allows these temp files to be compressed. The size of these files can get quite large. The data to be converted was UTF-8 encoded data. So, we are using  OutputStreamWriter, where we specify the encoding of the data. If you do not need the encoding, just remove that parameter from the constructor call of OutputStreamWriter. The system where this ran, supported Java 7, so have not used features in java 8, such as try with exceptions. import java.io.*; im...

So now It turns out that the data was getting saved unnecessarily on refreshing the page. For that I stumbled across a forum where I found the solution.(It works for IE only) Q.How to disable function key F5? Ans: document.attachEvent("onkeydown", my_onkeydown_handler); function my_onkeydown_handler() { switch (event.keyCode) { case 116 : // 'F5' event.retur...
