Spring Boot, parsing the pom.xml


Spring Boot can be easy to start up:options

Diving right in letting Spring Boot introductions be covered in another blog....

One way is to navigate to:  https://start.spring.io and find a page like the below:







Just select the options then click Generate (not shown).  This will download a zip file which can then be imported easily into your IDE.  I use STS eclipse, after import, the result was:


Because I selected Maven, there is a pom.xml file which is instructive.  It includes the necessary dependencies.  I could have specified them on the web page, but I usually just paste them in.

Below is the pom.xml file contents from the demo:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.0.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<groupId>com.example</groupId>
<artifactId>demo</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>demo</name>
<description>Demo project for Spring Boot</description>

<properties>
<java.version>1.8</java.version>
</properties>

<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
<exclusions>
<exclusion>
<groupId>org.junit.vintage</groupId>
<artifactId>junit-vintage-engine</artifactId>
</exclusion>
</exclusions>
</dependency>
</dependencies>

<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>

</project>

Note that it includes the Spring Boot version as well as the Java version.

This method is common and preferred by many, but from within STS, we can also just use File>New> New Spring Starter project as below:


Note that we have the same options as the online version.

Thus, a general overview of Spring Boot starters.

Subjects for further explanation would be Maven and pom.xml details, Maven versus Gradle, and the WAR packaging option.

Coding Philosophy

Coding Philosophy/Goals/Mindset: Achieve business and technical requirements Agility means these may change as the environment changes, or coding realities drive changes upstream We must adapt to these changes Consider those (including yourself) who will be reading/modifying the code : Extensibility How easily can new features be added? Readability Includes formatting, proper ID naming, and good quality comments--not too many Maintainability How easy will it be to make changes to this code? Scalability What about growth?  For example, another server, or database may be required Efficiency Especially for larger projects, it is important to minimize resource consumption Project velocity While subordinate to the above and within the bounds of efficiency completing quickly/on-time matters There are many techniques and guidelines for achieving the above such as avoiding magic numbers (use constants) and keeping methods short and single purpose. ...

Java: Reference vs. Object

Image
Declaring and initializing reference variables When learning Java we see reference variables declared and initialized like this: Case A:  ABC varName = new ABC(); Later in our learning, we see something like this: Case B:  ABC varName = new DEF(); Let's take this as an example for discussion: Dthing varName = new Othing(); What is Dthing and what is Othing? From the first chapters of introduction to Java we know that Dthing is the type, and Othing is a constructor, and so is the class of varName. More advanced instruction shows: Dthing is the Declared Type, or Reference Type (I have found them used interchangeably) Othing is the Object Type This vocabulary is needed for reasons including discussion about when to declare/instantiate with the Declared Type being the same as the Object type, and when they should be different. An example of that decision would be in the below. The why is another subject/post: List<String> varStrin...
