Build Spring Boot application in just 5 minutes


Spring Boot

Spring Boot is Spring's convention-over-configuration solution for creating stand-alone, production-grade Spring-based Applications that you can "just run".

You can use Spring Boot to create Java applications that can be started using java -jar or more traditional war deployments.

Features:

  • Create stand-alone Spring applications
  • Embed Tomcat or Jetty directly (no need to deploy WAR files)
  • Provide opinionated 'starter' POMs to simplify your Maven configuration
  • Automatically configure Spring whenever possible
  • Provide production-ready features such as metrics, health checks and externalized configuration
  • Absolutely no code generation and no requirement for XML configuration
In this example we will see that just using two files Application.java and pom.xml we can create a sprint boot application. The advantage of spring boot is that it takes care of all the configurations and you can focus on your application code rather than spending time configuring your application

pom.xml


Application.java


Run your application from IDE









Alternatively,  you can use spring boot maven plugin by executing 'run' goal spring-boot:run










Also, You can package your application mvn package








You can also run jar from command line, 'cd' into your target folder and execute  java -jar spring-boot-1.0-SNAPSHOT.jar

Generate/Read an Excel file in Java using Apache POI

Image
In this tutorial, we will find how to generate and read excel files in java using apache poi. Apache POI is a library which is created to work with Microsoft office formats. You'd use HSSF if you needed to read or write an Excel file using Java (XLS). You'd use XSSF if you need to read or write an OOXML Excel file using Java (XLSX). The combined SS interface allows you to easily read and write all kinds of Excel files (XLS and XLSX) using Java. Additionally, there is a specialized SXSSF implementation which allows writing very large Excel (XLSX) files in a memory-optimized way. In maven we have two separate dependencies for each type. poi artifact id used for .xls files and poi-ooxml used for .xlsx files. Find this project on Github https://github.com/javacodenet/excelDemo pom.xml ExcelApplication.java Employee.java ExcelHelper.java ...
