 一、问题描述：

搭建hibernate环境时，使用hibernate-distribution-3.3.1.GA-dist和slf4j-1.7.7。配置文件和程序OK之后，运行程序出现如下问题：

二、原因分析：jar包版本冲突

类 org.slf4j.impl.StaticLoggerBinder在hibernate-distribution-3.3.1.GA-dist\hibernate-distribution-3.3.1.GA\lib\required\slf4j-api-1.5.2.jar中是类的公有静态变量: 

public static final StaticLoggerBinder SINGLETON = new StaticLoggerBinder();

而在slf4j-1.7.7\slf4j-log4j12-1.7.7.jar中是私有变量: 

private static final StaticLoggerBinder SINGLETON = new StaticLoggerBinder();

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

                 2. 将slf4j-api-1.5.2.jar替换为slf4j-1.7.7\slf4j-api-1.7.7.jar，问题可解决。

 

三、jar包附图

技术分享

　　如果需要注解或和其他框架整合，则另行导入，各jar作用不再赘述。
