Anabolic Steroids: Uses, Abuse, And Side Effects

**Key Take‑aways for gitlab.zb100.com each section**

| Section | Core Concepts & Practical Points |
|---------|----------------------------------|
| **1 – What is a Micro‑service?** | • A small, autonomous service focused on a single business capability.
• Self‑contained: runs in its own process, has its own data store, and exposes a clear API.
• Deployed independently; can be updated or scaled without touching other services. |
| **2 – Micro‑services vs. SOA** | • SOA = "service" + "orchestration"; micro‑services are SOA but with:
 — tighter boundaries (one business concern).
 — independent deployment.
 — lightweight communication (usually HTTP/REST or gRPC).
 — smaller teams own each service. |
| **3 – Designing a Micro‑service** | 1️⃣ Identify the bounded context / domain that the service will encapsulate.
2️⃣ Define its public API (endpoints, messages).
3️⃣ Decide data ownership: one DB table or schema per service.
4️⃣ Choose technology stack matching team skill set and service needs.
5️⃣ Add health‑check & metrics endpoints for observability. |
| **4 – Tech Choices** | • Language: Go, Java, Kotlin, Python, Node.js – pick what the team is comfortable with.
• Frameworks: Spring Boot (Java/Kotlin), Micronaut, Gin (Go), FastAPI (Python).
• Build tools: Maven/Gradle (Java), Go modules, pipenv/poetry (Python). |
| **5 – Observability** | • Health‑check endpoints ( `/health`, `/ready` ).
• Metrics (Prometheus format) – expose via `/metrics`.
• Structured logs with JSON payloads for easy parsing. |
| **6 – Deployment** | • Build a Docker image.
• Push to registry (Docker Hub, GitLab Container Registry).
• Deploy as a container on any host or Kubernetes cluster. |

## 2️⃣ Sample Implementation

Below is a minimal but complete example that satisfies all the constraints.
Feel free to copy‑paste it into your favorite IDE and run.

### ? pom.xml (Maven)

```xml

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">

4.0.0
com.example
spring-demo
1.0-SNAPSHOT






org.springframework.boot
spring-boot-maven-plugin
3.1.0



repackage














```

In this example, the `spring-boot-starter-parent` is used as the parent for the project. This provides a number of defaults and simplifies dependency management.

You can add dependencies like `spring-boot-starter-web`, `spring-boot-starter-data-jpa`, etc., depending on your project's needs.

The Spring Boot Maven plugin is included by default in the spring-boot-starter-parent, so there's no need to explicitly declare it unless you want to customize its behavior. If you do want to add custom configuration for the Spring Boot Maven plugin, you can do it as follows:

```xml



org.springframework.boot
spring-boot-maven-plugin




```

But again, unless you need to modify the plugin's behavior, it's not necessary.

Now, to answer your question: if you're looking for a concise way to add the Spring Boot Maven plugin with minimal boilerplate, and assuming you have all the necessary dependencies (e.g., spring-boot-starter-parent as parent), then you can simply declare the plugin in your pom.xml under the section without any additional configuration.

This is effectively what you see in the example. No special macro or syntax is needed beyond the standard Maven XML structure."

Thus the answer contains that code snippet:

```

4.0.0
com.example
demo
1.0-SNAPSHOT


11









org.springframework.boot
spring-boot-maven-plugin




```

But the answer may also include a sample `pom.xml` for Gradle:

```
plugins
id 'org.springframework.boot' version '2.5.4'
id 'io.spring.dependency-management' version '1.0.11.RELEASE'
id 'java'


group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

repositories
mavenCentral()


dependencies
implementation 'org.springframework.boot:spring-boot-starter-web'
testImplementation('org.springframework.boot:spring-boot-starter-test')

```

Also may include a sample `build.gradle`:

```
plugins
id 'java-library'
id 'com.github.johnrengelman.shadow' version '7.0.0'


group = 'com.example'
version = '1.0-SNAPSHOT'

repositories
mavenCentral()


dependencies
implementation "org.springframework.boot:spring-boot-starter-web"
testImplementation "junit:junit:4.13.2"

```

Also may include a sample `pom.xml` snippet for Maven:

```

4.0.0

com.example
demo-app
1.0-SNAPSHOT
jar


UTF-8
11





org.springframework.boot
spring-boot-starter-web
2.5.4



```

In this example, we have a basic Maven project setup with a few dependencies such as Spring Boot Starter Web and Java version set to 11. Feel free to add or modify the dependencies based on your project's requirements.

Please note that this is just an example, and you may need to adjust it according to your specific needs.

Sure! Here’s a sample `pom.xml` file for a Maven project that includes basic configuration settings such as group ID, artifact ID, version, and some common plugins:

```xml
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/1.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

4.0.0


com.example
my-project
1.0-SNAPSHOT
