# Introduction In this project, you will learn how to implement a simple Chinese-English message switching system using the Inversion of Control (IoC) design pattern and the Spring framework. ## 👀 Preview ```bash [INFO] ------------------------------------------------------- [INFO] T E S T S [INFO] ------------------------------------------------------- [INFO] Running com.labex.TestGreeting 你好, Labex Hello, Labex [INFO] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 1.056 s - in com.labex.TestGreeting [INFO] [INFO] Results: [INFO] [INFO] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0 [INFO] [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------ [INFO] Total time: 11.295 s [INFO] Finished at: 2024-05-10T12:05:55Z [INFO] ------------------------------------------------------------------------ ``` ## 🎯 Tasks In this project, you will learn: - How to create an `IMessage` interface with an abstract `doMessage()` method - How to implement the `IMessage` interface in two concrete classes: `MessageCN` and `MessageEN` - How to configure the message beans using the `applicationContext.xml` file - How to test the message switching functionality in the `TestGreeting` class ## 🏆 Achievements After completing this project, you will be able to: - Use the IoC design pattern to decouple the implementation of message functionality from the main application - Use the Spring framework to configure and manage the message beans - Write unit tests to verify the functionality of the message switching system
