Customize Spring Boot's auto configurations

In this tutorial, we will customize the spring boot's auto configurations. This can be done in following ways:
  • Through program arguments
  • application.properties
  • application.yml
    • YAML is a serialization format that follows the hierarchical structure, which is in ways similar to JSON. It will contain key value pairs in a hierarchical format. And it is really popular in ruby. Spring dependencies have snake yaml jar which is responsible for parsing yaml.
Spring boot gives developers choices, often there are multiple methods to achieve the same thing in spring boot. This allows developers to pick their favorite approach.

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.
