Spring Boot Gradle vs Maven

Gradle and Maven are both build tools that can be used to build Spring Boot applications. However, there are some key differences between the two tools.

Gradle is a newer build tool that is based on the Groovy programming language. Gradle is known for its flexibility and expressiveness. It also has a number of features that make it well-suited for building Spring Boot applications, such as support for multi-project builds, dependency management, and task execution.

Maven is an older build tool that is based on XML. Maven is known for its simplicity and convention over configuration approach. It also has a large community of users and a wide range of plugins available.

Here is a table that summarizes the key differences between Gradle and Maven:

Characteristic	Gradle	Maven
Language	Groovy	XML
Flexibility	More flexible	Less flexible
Simplicity	Less simple	More simple
Convention over configuration	Less convention over configuration	More convention over configuration
Community	Smaller community	Larger community
Plugins	Fewer plugins available	More plugins available

Which one should you choose?

If you are new to build tools, or if you need to build a simple Spring Boot application, then Maven is a good choice. Maven is easy to learn and use, and it has a large community of users and a wide range of plugins available.

However, if you need to build a complex Spring Boot application, or if you need a more flexible build tool, then Gradle is a good choice. Gradle is well-suited for building multi-project builds and for managing complex dependencies.

Here are some additional things to consider when choosing between Gradle and Maven:

• Learning curve: Gradle has a steeper learning curve than Maven. This is because Gradle is a more flexible and expressive build tool.
• Plugins: Gradle has fewer plugins available than Maven. However, Gradle comes with a number of built-in plugins that are useful for building Spring Boot applications.
• Community support: Maven has a larger community than Gradle. This means that there are more resources available to help you if you are having trouble with Maven.

Ultimately, the best way to decide which build tool to use is to consider your specific needs and preferences.

Spring Boot YML vs Properties file

Spring Boot supports both YAML and properties files for configuration. YAML is a superset of properties, which means that it can do everything that properties files can do, plus more.

YAML is a human-readable data serialization format that is more concise and expressive than properties files. YAML uses indentation and whitespace to define the structure of the data, which makes it easier to read and write. YAML also supports nested data structures, which can be useful for complex configurations.

Properties files are a simpler format that is more widely supported than YAML. Properties files are simply text files that contain key-value pairs. The key and value are separated by a colon, and each line in the file represents a single key-value pair.

Which should you choose?

If you are new to Spring Boot, or if you need to support a wide range of environments, then it is generally recommended to use properties files. Properties files are more widely supported than YAML, and they are easier to understand and troubleshoot.

However, if you are comfortable with YAML, or if you need to configure complex data structures, then you can use YAML for your Spring Boot configuration. YAML is more concise and expressive than properties files, and it can make your configuration files easier to read and write.

Here are some additional things to consider when choosing between YAML and properties files:

• Tooling: There are more tools available for editing and validating YAML files than for properties files. This can be helpful if you are working on a complex configuration.
• Version control: YAML files are easier to version control than properties files. This is because YAML files are more structured and easier to parse.
• Community support: There is a larger community of developers who use YAML than there is of developers who use properties files. This means that there are more resources available to help you if you are having trouble with YAML.

Ultimately, the best way to decide which format to use is to consider your specific needs and preferences.

Spring Boot application change port

There are two ways to change the port of a Spring Boot application:

1. Using the server.port property: This is the most common way to change the port of a Spring Boot application. You can set the server.port property in the application.properties or application.yml file. For example, to set the port to 9000, you would add the following line to your configuration file:

server.port=9000

2. Using the --server.port command-line argument: You can also change the port of a Spring Boot application using the --server.port command-line argument. For example, to start the application on port 9000, you would use the following command:

java -jar my-application.jar --server.port=9000

Which method you use to change the port of your Spring Boot application depends on your preference. If you are deploying your application to a production environment, it is generally recommended to set the server.port property in your configuration file. This will make it easier to manage the port of your application.

Note: If you are using Spring Boot Actuator, you will also need to change the port of the actuator endpoints. You can do this by setting the management.port property in your configuration file.

Here is an example of a Spring Boot configuration file that sets the port to 9000 and the actuator port to 9001:

server.port=9000
management.port=9001

Once you have changed the port of your Spring Boot application, you can start the application as usual.
