运行maven项目时出错：无法加载配置类org.springframework.cloud.bootstrap.config.PropertySourceBootstrapConfiguration

【问题标题】：Error on running maven project :Cannot load configuration class org.springframework.cloud.bootstrap.config.PropertySourceBootstrapConfiguration运行maven项目时出错：无法加载配置类org.springframework.cloud.bootstrap.config.PropertySourceBootstrapConfiguration
【发布时间】：2021-08-09 11:28:24
【问题描述】：

我需要帮助来解决运行 maven 项目时出现的以下错误。 我正在使用 java 8、maven 3.8.1 和 STS 版本：4.11.0.RELEASE。 我能够成功地进行 maven clean 和 maven 安装，但是在本地 MacOS Big Sur 上运行项目时出错。 我需要更改 maven 版本或 cglib 库版本吗？ 请帮帮我。

编辑 1： 添加了正在使用的java版本的截图。

【问题讨论】：

  • 这看起来像问题：Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain) throws java.lang.ClassFormatError accessible: module java.base does not "opens java.lang" to unnamed module。问题看起来像使用 module-info.java ...此外，您没有使用 JDK 8 来运行您的应用程序...您应该添加更多信息，您正在使用哪个 Spring Boot 版本等。
  • @khmarbaise 我已经添加了详细信息。能不能把你提到的问题说明一下，真的很棒。
  • 错误信息肯定不是来自运行在 JDK8 上的应用程序。请仔细检查。控制台视图上的标题栏应显示启动应用程序时使用的 JDK 安装。
  • @MartinLippert 你是怎么知道 JDK 8 没有被使用的。
  • @Akash java.base/ 出现在您从正在运行（失败）的应用程序发布的日志中，它指的是在 JDK9 及更高版本中引入的基本模块。这在 JDK8 中不存在。

【解决方案1】：

问题是，我使用 JDK 1.8 和 JRE 16 来运行应用程序。 我首先安装了 JDK 16，然后删除了 JDK 16 并安装了 JDK 1.8。所以使用的 JDK 是 1.8，但默认情况下选择了最高版本的 JRE。 请查找附件图片。
