RedisSessionUtil报错，求助

Question

使用框架为ssm，用户登录时，使用shiro校验。
我的工作环境在mac上，但同样一套代码在windows下运行正常???

Subject subject = SecurityUtils.getSubject();
UsernamePasswordToken usernamePasswordToken = new UsernamePasswordToken(member.getUsername(),Md5Util.saltPassword(member.getUsername(), password));
usernamePasswordToken.setRememberMe(true);
subject.login(usernamePasswordToken);

执行到上面的 subject.login(usernamePasswordToken); 语句时报如下错误：

Answer 1

我的出错原因在于如下语句：

p.load(RedisSessionUtil.class.getClassLoader().getResourceAsStream("config/session.properties"));

其中的 session.properties 该配置文件未放置在 config。

---

但我有一点不懂不明白，为什么同一套代码在windows下能正常运行，在mac上却报错？？？

Answer 2

java.lang.NoClassDefFoundError: Could not initialize class com.cc.cache.redis.util.RedisSessionUtil...
RedisSessionUtil的静态代码块出现异常导致无法初始化，debug一下看看
