我为我的项目构建了一个基于spring boot的jar。一旦我启动某个功能,我就会遇到以下异常:
SEVERE:servlet [dispatcherServlet]的Servlet.service()与path []的上下文抛出异常[Handler dispatch failed;嵌套异常是java.lang.NoClassDefFoundError:com / google / common / collect / Lists]的根本原因 java.lang.ClassNotFoundException:com.google.common.collect.Lists
我已经在我的家属中添加了番石榴:
<!-- https://mvnrepository.com/artifact/com.google.guava/guava -->
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>19.0</version>
</dependency>
还尝试了其他版本,如23.6-jre和24.1-jre,但似乎没有任何工作..
我的代码中出现的异常是在使用
时return Lists.reverse(myList);
此时我不知道可能出现什么问题,我非常感谢任何帮助!
编辑:
当我尝试时 mvn安装 我收到以下错误消息:
