Spring Boot3 从 2.7.10升级到3.1.5有以下几个点需要注意。JDK版本支持从JDK 17-19版本javax.servlet切换到jakarta.servletspring.redis配置切换为spring.data.redisSpring Cloud 2022.0.4Spring Cloud Alibaba 2022.0.0.0Spring Boot3 升级参考文档spring boot升级参考spring cloud升级参考spring cloud alibaba升级参考SpringBoot3版本代码示例GitHub - jeecgboot/JeecgBoot at springboot3查看springboot父级项目和依赖项目是否有依赖 springboot2.7.18若有责需要需要升级到3.1.5相关依赖版本!-- 微服务 --

官方不再将构建制品发布到maven中央仓库了而是发布在了alfresco仓库这就需要我们仓库才能正确下载依赖.在pom中添加repositories标签然后再添加repository标签。如果repositories已经有了切不要再添加而是将repository标签和里面的内容复制进去。最终效果如下repositories repository idactiviti-releases/id
