解决Java.lang.ClassNotFoundException的方法

检查项目的构建工具（如Maven或Gradle）配置文件，确保所需的依赖项已正确声明。如果你使用的是Maven或Gradle等构建工具，可以尝试手动删除本地存储库中的依赖项，并重新构建项目以重新下载依赖项。有时，使用较新的编译器版本可能会导致与旧版本的依赖项不兼容的问题。通过检查类路径、依赖项是否存在、类名和包名是否正确以及编译器版本是否兼容，你应该能够解决Java.lang.ClassNotFoundException异常。检查代码中的import语句和类的使用位置，确保它们与实际的类文件匹配。

Trae插件的Builder模式为开发者提供了一种高效的项目搭建方式，通过自然语言描述需求，能够快速生成项目框架和核心代码，减少重复性工作。本文以开发端午包粽子小游戏为例，展示了Trae插件的安装、使用及功能特点。通过自然语言描述，插件能够理解并生成项目结构、代码文件，并提供开发路线图建议。在实际开发中，虽然自然语言描述的精准度对生成结果有影响，但Trae插件在代码生成效率和项目搭建速度上表现出色，尤其适合中小项目和特定类型应用的快速开发。未来，插件在复杂大型项目的高度定制化开发方面仍有提升空间。

我看有些文章说需要引入hibernate-validator，其实是对的，但细心的你会发现，spring-boot-starter-validation已经引入了hibernate-validator的依赖，所以不需要二次引入了。最后需要检测是否使用了@Validated注解，并且该注解需标注在Controller类上，而不是方法或者PathVariable参数上，我测试了只有标注在类上才会生效。首先确认是否引入了spring-boot-starter-validation依赖。
