课程名称：使用Kotlin和Spring Boot构建RESTFUL APIs 课程概述：Kotlin是一种现代、简洁且安全的编程语言，如今在JVM语言中极为流行。它与Java和其他语言兼容，提供了多种跨平台代码重用方式，促进高效编程。本课程将重点介绍如何利用Kotlin进行服务器端开发，使用Spring Boot框架。课程采用纯实践的方式，涵盖以下两个主题：对于Java开发者必要的Kotlin基础知识，以及使用Spring Boot和Kotlin构建RESTFUL APIs。 课程内容包括： 1. **课程入门**：了解课程目标及所需先决条件。 2. **Kotlin编程语言简介**：介绍Kotlin语言及其在企业开发中的优势。 3. **Kotlin基础**：探索Kotlin的基础知识，包括变量、基本类型、条件语句、循环等。 4. **Kotlin中的函数**：学习如何定义和使用函数，包括默认参数和命名参数。 5. **类、接口与继承**：详细讲解类、接口及其继承关系。 6. **处理空值**：学习如何在Kotlin中处理空值和空类型。 7. **集合、数组与Lambda表达式**：介绍Kotlin的集合和Lambda表达式的使用。 8. **异常处理**：讨论Kotlin中的异常处理技术。 9. **作用域函数**：学习Kotlin中的作用域函数及其用法。 10. **Kotlin与Spring Boot入门**：了解将要构建的应用概述并创建简单API。 11. **使用JUnit 5进行集成/单元测试**：学习使用JUnit 5编写测试用例。 12. **构建课程目录服务**：创建课程实体及相关API端点。 13. **控制器层单元测试**：编写控制器单元测试。 14. **使用Validator和ControllerAdvice进行Bean验证**：学习如何应用Bean验证和异常处理。 15. **使用Spring Data JPA编写自定义JPA查询并测试数据库层**：掌握自定义查询与数据库测试技巧。 16. **使用@RequestParam通过名称检索课程的GET端点**：掌握@RequestParam的使用。 17. **使用Spring Data JPA的实体关系**：讲解在JPA中表达实体关系的技巧。 18. **与Postgres数据库集成**：学习如何将Postgres数据库与服务集成。 19. **使用TestContainers进行集成测试**：配置TestContainers以进行集成测试。 20. **Java与Kotlin互操作性**：学习Java与Kotlin之间的互操作性。 课程结束时，学员将能够熟练使用Kotlin编程语言，并使用Spring Boot和Kotlin构建RESTFUL APIs。
Kotlin is the Modern, concise and safe programming language and is one of the popular JVM language in this day and age.It's also interoperable with Java and other languages, and provides many ways to reuse code between multiple platforms for productive programming.This course will focus on using Kotlin for Server-Side Development using SpringBoot framework. This is a pure hands-on oriented course which covers these two topics:Covers Kotlin Fundamentals thats necessary for Java DevelopersBuild RestFul APIs using SpringBoot and KotlinSection 1: Getting Started With the CourseThis section covers the course objectives and the prerequisites that are needed to make the most out of this course.Section 2: Getting Started with Kotlin Programming LanguageIn this section, I will introduce you to Kotlin Programming Language and why its a powerful language for enterprise development.Introduction to KotlinHow Kotlin Works with the JVM?Section 3: Kotlin FundamentalsIn this section, we will explore the fundamentals of Kotlin.val & var variables in KotlinBasic Types -
