[ERROR] [2017-12-28 14:42:39][org.springframework.web.context.ContextLoader]Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hotelDao' defined in file [C:\apache-tomcat-7.0.52\webapps\4G\WEB-INF\classes\spring-dao.xml]: Cannot resolve reference to bean 'datastore' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'datastore' defined in file [C:\apache-tomcat-7.0.52\webapps\4G\WEB-INF\classes\spring-morphia.xml]: Cannot resolve reference to bean 'morphia' while setting bean property 'morphia'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'morphia' defined in file [C:\apache-tomcat-7.0.52\webapps\4G\WEB-INF\classes\spring-morphia.xml]: Invocation of init method failed; nested exception is java.lang.IncompatibleClassChangeError: Implementing class

Answer 1

名称或ID为：morphia 的bean初始化失败，原因：出现了IncompatibleClassChangeError 异常，而morphia对应的class 可能由于maven依赖包的缘故出现了多个版本导致冲突，检查该class类是否出现在多个jar包中。如果有超过1个jar包文件包含该类，修改maven的依赖配置并重新打包。
