在Spring Security中找不到WebSecurityConfigurerAdapter【Kotlin服务器端编程实践开发】
首先
我将总结一下我在阅读以下书籍时遇到的困难内容。
請問有什麼問題嗎？
在P187的書籍中，Intellij出現了找不到模塊的錯誤。
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder
解决方案
我发现 Spring Security 6系已经被废弃了，如果在 spring-boot-starter-security 中引入 spring-security-config，会自动安装最新的6系，因此找不到它。
然后我只需指定Spring Security的版本来安装，具体如下：
implementation("org.springframework.boot:spring-boot-starter-security")
implementation("org.springframework.security:spring-security-config:5.6.10")
然后我成功地导入了WebSecurityConfigurerAdapter。
其他问题
尽管已经能够执行，但是如果使用此方法执行，会发生以下错误，导致无法继续进行书籍的进展。

最近发生了一些变化，似乎已经废弃了的设置方式被记录了下来，所以需要使用新的方式进行设置。然而，由于这超出了学习的范围，我决定跳过第7章。
如果有人读到第7章，请告诉我设置。
添加说明：关于spring-security的配置。
2022年12月，Spring Security升级到版本6，并改变了配置文件的编写方式。为了让大家能够通过以下的实践学习，我们准备了相应的教学材料。如果按照书中的指导进行操作，您将能够成功地执行第7章的内容。
在结束时
在这本书中，我遇到了很多困难，并努力解决了它们，但是重新编写全部设置实在太困难了，而且偏离了我本来想学习的内容，因此我选择放弃了这个选项。
希望今年能够出版一本解说Kotlin新型Web应用程序的书籍。
