java - ClassNotFoundException 异常-6ren

java - ClassNotFoundException 异常

转载作者：行者123 更新时间：2023-11-28 22:17:05

我已经使用 jersey 2 和 spring 4 开发了一个项目，但是我不得不用 jersey 1.19 替换 jersey 2，当我这样做时我得到一个名为“java.lang.ClassNotFoundException: com.sun.jersey.core .util.FeaturesAndProperties”，当在 tomcat 服务器上运行时。是否从 jersey 2 迁移到 jersey 1.19 导致此异常？谢谢

最佳答案

处理这类问题的方法-

首先关闭您的 IDE 并从您的项目目录中删除 target、.setting 和 .classpath。

1) 仔细检查 pom.xml 中是否有多个相同但不同版本的依赖项，如果是，请将其删除并运行命令 mvn clean install -U。如果不行的话

2) 找到 .m2 目录并在此目录中搜索 lastupdate 文件并删除所有这些文件并运行命令 mvn clean install -U。如果不行的话

3) 删除 .m2 目录并清理并安装 maven。
