启动失败了,报了如下错误:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘ehCacheCacheManager‘ defined in class path resource [org/springframework/boot/autoconfigure/cache/EhCacheCacheConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [net.sf.ehcache.CacheManager]: Factory method ‘ehCacheCacheManager‘ threw exception; nested exception is net.sf.ehcache.CacheException: java.lang.annotation.IncompleteAnnotationException: org.terracotta.statistics.Statistic missing element type
以前一直在用,没有问题,新项目报错。
新项目唯一不同的是尝试了easyexcel,我好像知道些什么了。
查看easyexcel的pom.xml,找到了这个。
<dependency> <groupId>org.ehcache</groupId> <artifactId>ehcache</artifactId> <version>3.4.0</version> </dependency>
基本上定位问题所在了,org.ehcache和net.sf.ehcache有冲突,那么既然easyexcel已经引用了,我们就去掉net.sf.ehcache。
然后依然报错,有了新的提示,告诉我们无法连接redis,懂了。
那么我们尝试一下用net.sf.ehcache,排除org.ehcache。
<dependency> <groupId>com.alibaba</groupId> <artifactId>easyexcel</artifactId> <version>2.2.3</version> <exclusions> <exclusion> <groupId>org.ehcache</groupId> <artifactId>ehcache</artifactId> </exclusion> </exclusions> </dependency>
启动成功了。
