问题描述
我试图在秋千应用程序中使用Hibernate 3.5.1决赛 这是我正在使用的罐子: Hibernate-core-3.5.1-Final Hibernate-EntityManager-3.5.1-Final Hibernate-JPA-2.0-API-1.0.0.0.-Final Hibernate-Annotations-3.5.1-Final Hibernate-Commons-Annotations-3.2.0.-Final dom4j-1.6.1 slf4j-api-1.6.4 slf4j-log4j12-1.6.4当我尝试运行该应用程序时，我会收到以下错误: Failed to instantiate SLF4J LoggerFactory Reported exception: java.lang.NoClassDefFoundError: org/apache/log4j/Level at org.slf4j.LoggerFactory.bind(LoggerFactory.java:128) at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:108) at org.slf4j.LoggerFactory.getILoggerFactory(LoggerFactory.java:279) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:252) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:265) at org.hibernate.cfg.Configuration.(Configuration.java:165) at org.hibernate.ejb.Ejb3Configuration.(Ejb3Configuration.java:127) at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:54) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:48) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:32) at com.xeno.xecamp.desktopManagement.Main.main(Main.java:16) Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Level at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) ... 11 more Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/Level at org.slf4j.LoggerFactory.bind(LoggerFactory.java:128) at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:108) at org.slf4j.LoggerFactory.getILoggerFactory(LoggerFactory.java:279) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:252) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:265) at org.hibernate.cfg.Configuration.(Configuration.java:165) at org.hibernate.ejb.Ejb3Configuration.(Ejb3Configuration.java:127) at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:54) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:48) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:32) at com.xeno.xecamp.desktopManagement.Main.main(Main.java:16) Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Level at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) 推荐答案您还需要在类路径中包括log4j jar文件. 请注意，slf4j-log4j12-1.6.4.jar只是一个适配器，可以通过SLF4J API使用log4j.它不包含log4j的实际实现. 其他推荐答案您需要下载 log4j 并添加在您的classPath中. 其他推荐答案在我的环境中，我只是将两个文件添加到类路径中.而且工作正常. slf4j-jdk14-1.7.25.jar slf4j-api-1.7.25.jar本文地址：https://www.itbaoku.cn/post/741778.html?view=all |
