Guice vs Spring: What are the differences?

# Introduction
This Markdown code will outline the key differences between Guice and Spring for easy reference on a website.

1. **Configuration Style**: Guice uses a programmatic configuration style where bindings are directly written in code, while Spring relies on XML or annotation-based configuration files which allows for more flexibility and separation of concerns.
2. **Lightweight vs. Heavyweight**: Guice is lightweight and focused solely on dependency injection, providing a simpler and faster start-up time, whereas Spring is a more extensive framework offering a wide range of features beyond just dependency injection, which can lead to a slightly longer start-up time.
3. **Container Management**: In Guice, the developer is required to manage the lifecycle of objects, whereas Spring provides a built-in container that can manage the object lifecycle, easing the burden on developers.
4. **Integration with Other Frameworks**: Spring has better integration with other frameworks and technologies like Hibernate, JPA, and AspectJ, due to its broader scope, while Guice is more focused on providing seamless dependency injection functionality.
5. **Community and Support**: Spring has a larger community and extensive documentation, making it easier for developers to find solutions to problems, whereas Guice has a smaller community and may have limited resources for support.
6. **Aspect-Oriented Programming (AOP)**: Spring supports AOP out of the box, allowing developers to easily implement cross-cutting concerns, while Guice does not provide built-in support for AOP, requiring developers to use third-party libraries for AOP functionality.

In Summary, Guice and Spring differ in configuration style, weight, container management, integration capabilities, community support, and AOP functionality within their respective frameworks.
