java.lang.IllegalAccessError: tried to access field org.slf4j.impl.StaticLoggerBinder.SINGLETON from class org.slf4j.LoggerFactory

java.lang.IllegalAccessError: tried to access field org.slf4j.impl.StaticLoggerBinder.SINGLETON from class org.slf4j.LoggerFactory

使用hbm2java时,使用hibernate-distribution- 3.3.1.GA-dist版本,做好了程序和配置文件后,运行程序出现Exception in thread "main" java.lang.IllegalAccessError: tried to access field org.slf4j.impl.StaticLoggerBinder.SINGLETON from class org.slf4j.LoggerFactory错误。



问题原因:jar文件版本冲突

类 org.slf4j.impl.StaticLoggerBinder在slf4j-api 中是类的公有静态变量:




public static final StaticLoggerBinder SINGLETON = new StaticLoggerBinder();


而在slf4j-log4j12(slf4j-nop.jar, slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar其中之一)中确是私有变量:



private static final StaticLoggerBinder SINGLETON = new StaticLoggerBinder();



解决方案:1.修改slf的源代码,将这个变量有私有改为公有,再打包,问题可解决。

                  2.slf4j-api.jar 删除,再导入同版本的slf4j-api-1.5.6.jar 和slf4j-log4j12-1.5.6.jar ,问题可解决。

slf4j-api.jar 在hibernate-distribution-3.3.1.GA-dist/lib/required文件夹下
