将 springboot 版本 2.1.18.RELEASE 升级到 2.7.16，并将 java 8 升级到 java 17 项目构建已成功完成，但当我在本地运行程序时出现以下错误。

将 springboot 版本 2.1.18.RELEASE 升级到 2.7.16，并将 java 8 升级到 java 17 项目构建已成功完成，但当我在本地运行程序时出现以下错误。

尝试过的方法：

添加了与不同版本的 Jakarta 版本（6.0.0、5.0.0）兼容的 jetty-server（11.x 和 12.x）依赖项

Tomcat 版本 9.x 和 10.x 已测试

PS：当我在代码中注释@EnableSwagger2时，错误不会出现，但我需要在代码中使用注释

没有尝试添加依赖项：springdoc-openapi-starter-webmvc-ui。

我想得到答案的问题：

  1. 如何解决这个错误？

  2. 除了添加 springdoc-openapi-starter-webmvc-ui 依赖或上述方法之外，还有其他方法吗？如果可能的话请解释一下原因。

提前致谢！

你的项目中的 spring 版本似乎混淆了。

  • SpringBoot 2.7.16 是基于 
    javax
    的版本
  • SpringBoot 3+ 是基于 
    jakarta
    的版本

在你提到的堆栈跟踪中，我看到你有

spring-core 6

[...]ReflectionUtils.getDeclaredMethods(ReflectionUtils.java:465) ~[spring-core-6.0.12.jar:6.0.12]

此版本的 spring-core 是基于 

jakarta
的（请参阅 Spring 框架版本 wiki）。

由于您的目标是 SB 2.7，因此您应该在 5.x 版本中拥有 spring-core。

为了修复您的项目，我建议

  • 检查 spring-core 6 依赖项的位置并修复该依赖项
  • 或移至 SB 3 目标版本（完全支持 Jakarta）
