JdonFramework的自带缓存问题（板桥先生进）？

weili0677
使用SJH做的项目，在长时间运行或者大量访问后老是会报如下的错误，并且一直在跳：
请问板桥先生，这是怎么回事？
我也在论坛中找到有一个人也是同样的问题(贴子：http://www.jdon.com/jivejdon/thread/32901)，板桥先生的建议是关掉Jdon的自带缓存(修改aspect.xml)，但是按照板桥先生的建议关闭后会直接报aop错误，本人是java新手，还望板桥先生详细指点。谢谢。

可能是你的JF版本有点低，我在47行没有看到代码，只有49行：
public void put(Object key, Object value) {
cache.put(key, value);
}

建议：
1.先下载使用最新JF
2.是不是ehcache等jar包没有，没有缓存报错。

weili0677 2011-04-02 10:01
谢谢板桥先生的回复
我是下载了JdonRails和struts1+hibernate_lib
然后以里面的mysjh为基础做的项目
难道struts1+hibernate_lib里面的jf版本是比较低的？还要用6.2.3的jf去替换吗？

是的，一般案例中的版本都比较低，都要用最新版本替代，本想用Maven，但担心对初学者有些麻烦，所幸jf版本更新不算太快。

weili0677 2011-04-02 10:06
好的，谢谢板桥先生。我先试试去啦。。
weili0677 2011-04-02 10:09
报错了。。新的jf在配置方面也有许些不同呀？蒙了。。

java.lang.NoSuchMethodError: ...

凡是NoSuchMethodError 基本都是版本冲突，存在两个JF，一个是旧的，一个是新的，你要确认替代了tomcat下lib目录，必须是关闭tomcat才能替换，不能有重名。

weili0677 2011-04-02 11:19
尝试了很多种替换方式，都不行呢。

单单只替换更新jdonframework.jar的时候：
直接用myeclipse自带的tomcat时报的是上面的这种错误
把项目打包到安装版的tomcat时启动是成功的，但是加载后又是报的另外的错误。

要慢慢测试了。唉，杯具啊。

banq 2011-04-02 12:19
主要是classpath，你要查看classpath先后，如果之前有一个路径里有jf，是老版本，就会有这个问题，所以，要替换就替换你机器里所有的jf，不用的多余的全部删除，保持一个调试方便。
weili0677 2011-04-02 13:27
谢谢板桥先生，现在我已经弄到可以正常启动tomcat了，不过，在加截完一些类后，就报如下错误了，麻烦再帮我看看，谢谢。。

没有类发现，缺少antl，这是hibernate需要的一个包，你把noclass found 冒号后面的缺少类名复制到google搜索，就能找到包含该文件的jar包。

的错误，是什么原因呢？也不影响使用。

banq 2011-04-02 15:02
使用缓存拦截器的地方有些没有进行空指针检查，java空指针报错是致命问题，你每使用一个对象，准备访问其内部方法或属性时，多留心眼检查它是否为空，怀疑性对待每一行代码。希望对你和其他初学者有用。
weili0677 2011-04-02 15:18
好的，谢谢，不过，我还不知道要怎么去检查呢。。因为我虽然在很多方用了try..catch,但是都没抓到这个错误。我也不清楚要从哪里入手以及怎样入手了。。。

如果板桥有时间不吝赐教的话，那就再感激不尽了。
