The module is presented as a tour of what happens behind familiar Spring features—from registering bean definitions to wiring dependencies and applying transactional behavior through proxies. The announcement describes the project and its intended examples; the repository, code, tests, license, and tested Spring version could not be independently verified from the available links.
What was announced
In a LinkedIn post, Tusha wrote, “I’ve now completed Module 13 — Spring Internals.” He describes spring-by-example as an open-source collection of small, focused Spring examples accompanied by explanations, tests, and documentation. The post’s stated aim is to look beyond how developers use Spring features and explain some of the mechanisms behind them.
The announcement is a project milestone, not a new Spring Framework release or an independent assessment of the module’s implementation. Its GitHub and GitLab links were shortened, and the canonical repository could not be verified. That means the module outline below reflects what the author says it covers, rather than a code audit.
What the module says it covers
Tusha lists nine subjects, spanning container configuration, bean creation, and behavior applied around method calls:

@Autowired @Transactionaland AOP proxiesBeanPostProcessorDefaultListableBeanFactoryConfigurationClassPostProcessor
The author’s descriptions connect these ideas: configuration and scanning contribute bean-definition metadata; the container uses definitions as it manages and resolves beans; injection points are processed; and proxies can surround transactional calls. He also says ConfigurationClassPostProcessor connects configuration metadata—including @Configuration, @Bean, @ComponentScan, and @Import—to bean definitions.
How to read the concepts as one sequence
A useful mental model is that Spring’s configuration describes what the container should manage, and the container uses that description to create and wire objects. Additional processing can participate in bean setup, while AOP proxies can add behavior around calls. In this module’s outline, transaction handling is an example of behavior associated with a proxy.
This is a conceptual synthesis of the announcement and Spring documentation, not a promise that every application follows one identical sequence or uses the same proxy strategy. The official references available for these concepts are historical Spring Framework 4.0 and 3.1 editions, so they should not be treated as current-version compatibility guidance: Spring Framework 4.0 reference and Spring Framework 3.1 reference.
What readers can—and cannot—take from the announcement
The module outline may be useful to readers who want an explanatory path from Spring configuration to container-managed objects and runtime behavior. The post presents the project as example-based and says it includes explanations, tests, and documentation, but the available evidence does not establish the number of examples or tests, their results, a Spring version, or learning outcomes. It also does not establish adoption or readership figures.

Before relying on the project for a particular application, readers would need to check its repository for the actual source, license, test coverage, and Spring version. For version-specific behavior, consult documentation matching the Spring Framework release in use rather than relying on the older reference editions cited above.

Tusha closes with a question for people who have used Spring: “what’s one part of the Spring framework you think developers commonly misunderstand?” It is an invitation to share perspectives, not evidence of a measured consensus about which concepts are most often misunderstood.
