jdk版本和导入的jar包不兼容导致的

http://blog.knowsky.com/260578.htm 看一下这个有没有帮助

yaoxunji 不是jar包的问题,我其他struts2工程都可以启动,就是这个整合spring的不行

)我刚学ssh框架没多久,想跟着视频做个项目。但是当我加好了jar包启动的时候,tomcat提示说没有log4j-core的jar包,我把这个log-core.2.8jar包加进去还是提示没有,我后来写了log4j2.xml才不报这个错,但是他居然报找不到hibernate的配置文件???![图片说明![图片说明](https://img-ask.csdn.net/upload/201709/10/1505033275_713982.png)](https://img-ask.csdn.net/upload/201709/10/1505033250_956276.png) 我之前刚测试了hibernate都能连上数据库 我靠!日志文件这么吊吗?有没有大佬帮帮我啊!![图片说明](https://img-ask.csdn.net/upload/201709/10/1505032988_390586.png)![![图片说明](https://img-ask.csdn.net/upload/201709/10/1505033425_837857.png)图片说明](https://img-ask.csdn.net/upload/201709/10/1505033318_489107.png)![图片说明](https://img-ask.csdn.net/upload/201709/10/1505033785_669715.png)

================================================= 不知道有没有人看? 我研究到现在,发现了很诡异的地方……现在增的功能也能实现了,我把roleAction类里的add方法名字换成save,然后jsp里那个也换了jsp的form里action="save",注意,这里没有后缀【我为什么强调后缀是因为这个很诡异的问题最直接的体现在于后缀】,之前写法是action="add",也没加后缀,访问时点击链接显示http://localhost:8080/SSHTEST/role_add【注意,此处后缀没带.action】,我要强调的是我设置了extension就是action,所以不带后缀时肯定是找不到显示404的。但是我的list方法和delete方法,同样的写法run的时候链接的地址都自己带上了.action,就add和edit不行。我甚至复制粘贴过去了,重写过了,都没用,就这2个方法的连接死活run的时候不带后缀。我无意中把add名字换成了save,也没做什么,突然就成功了……问题是add不是什么struts2的关键字,我想不通,给edit方法改了个名字,怎么改也还是连接中不出现后缀。我就再去折腾了一遍save方法,我又什么都不动,重新把save改成了add,果然,又不能新增了。然而我再改回save,此时竟然失效了,又显示连接不带后缀了。我只好ctrl+z恢复一下,然后又可以用了!!!不是输入法问题,我一直用的英文的输入法。我现在就觉得Struts2间歇性的抽风了!这个莫名其妙的问题让我今晚上又废在这里了。 来个有经验的大佬解答一下好不好?Struts2是2.5.14的。我真心觉得不是我代码问题,我都手动重写了两遍……复制黏贴改过两遍。都没用的。另外关于后缀的问题,我也试过注释那句extension只能是action。但是同样做到edit的时候报错 01:30:08.669 [http-nio-8080-exec-10] ERROR org.apache.struts2.dispatcher.Dispatcher - Could not find action or result: /SSHTEST/role_edit com.opensymphony.xwork2.config.ConfigurationException: There is no Action mapped for namespace [/] and action name [role_edit] associated with context path [/SSHTEST].

JSON解析——net.sf.json.JSONObject
简介 在程序开发过程中,在参数传递,函数返回值等方面,越来越多的使用JSON。JSON(JavaScript Object Notation)是一种轻量级的数据交换格式,同时也易于机器解析和生成、易于理解、阅读和撰写,而且Json采用完全独立于语言的文本格式,这使得Json成为理想的数据交换语言。 JSON建构于两种结构: “名称/值”对的集合(A Collection of name/va...

为什么猝死的都是程序员,基本上不见产品经理猝死呢?

程序员如何通过造轮子走向人生巅峰?
前言:你所做的事情,也许暂时看不到成果。但不要灰心,你不是没有成长,而是在扎根。 程序员圈经常流行的一句话:“不要重复造轮子”。在计算机领域,我们将封装好的组件、库,叫做轮子。因为它可以拿来直接用,直接塞进我们的项目中,就能实现对应的功能。 有些同学会问,人家都已经做好了,你再来重新弄一遍,有什么意义?这不是在浪费时间吗。 殊不知,造轮子是一种学习方式,能快速进步,造得好,是自己超强能力的表...
