To display the conditions report re-run your application with debug enabled.我感觉是环境问题 我就把jdk原17换为1.8的版本就好使了报错现象启动 SpringBoot 项目时抛出以下错误无法创建 JwtUtil Bean提示找不到类NoClassDefFoundError: javax/xml/bind/DatatypeConverter ClassNotFoundException: javax.xml.bind.DatatypeConverter报错原因JDK 版本兼容性问题JDK 1.8 内置javax.xml.bind相关依赖无需手动引入JDK 9 版本移除了javax.xml.bind模块导致项目运行时找不到对应类启动失败。解决方案方案 1快速解决推荐无需改代码将项目 JDK 版本从17 切换为 JDK 1.8完美兼容所有依赖启动即可正常运行。方案 2保留高版本 JDK不降级手动引入依赖如果不想更换 JDK 版本在pom.xml中手动添加 JAXB 依赖!-- JAXB API解决 JDK9 缺失 javax.xml.bind 问题 -- dependency groupIdjavax.xml.bind/groupId artifactIdjaxb-api/artifactId version2.3.0/version /dependency dependency groupIdcom.sun.xml.bind/groupId artifactIdjaxb-impl/artifactId version2.3.0/version scoperuntime/scope /dependency总结根本原因JDK 17 移除了 JAXB 模块老项目依赖不兼容最简方案直接降级为 JDK 1.8零代码修改快速恢复运行进阶方案保留高版本 JDK引入缺失的 JAXB 依赖即可。
