在这其中,prepare和execute方法是用作Action调用的入口函数,其他的接口定义都与Action执行时的运行参数和配置有关。 3.实现Action类: Struts2不要求 Action类继承任何的Struts2的基类或实现Struts2接口。(但是,我们为了方便实现Action,大多数情况下都会继承com.opensymphony.xwork2.ActionSupport类,并重写此类里的public St...
Struts2是一个兼容Struts1和WebWork的MVC框架,既然,提到了MVC框架,就不得不对MVC框架做一个简单介绍,仅限于简单介绍,如果,想了解更多的MVC的知识可以查看相关的文档,或者找一本Struts1的书籍,相信上面关于MVC的篇幅不会很少。言归正传,其实,Java目前出现的这些框架而言,其最终目的都是为了接触耦合,不论是Spring、H...

如果我们完全不考虑Action的执行环境,仅仅把Action看作一个普通的Java对象,那么我们甚至可以直接new一个Action的对象,通过执行其中的方法完成测试。这样,我们就不需要任何的Mock,来模拟Web容器的环境。 2. 结合Action的执行环境,使得Struts2在Control这个层次上,能够定义更加丰富的执行层次 ...
三月初,安全研究人员发现世界上最流行的JavaWeb服务器框架之一– Apache Struts2存在远程代码执行的漏洞,Struts2官方已经确认该漏洞(S2-046,CVE编号为:CVE-2017-5638)风险等级为高危漏洞。 漏洞描述 该漏洞是由于上传功能的异常处理函数没有正确处理用户输入的错误信息,导致远程攻击者可通过修改HTTP请求头中的Content-Ty...

A plain Validator (non FieldValidator) that gets short-circuited will completely break out of the validation stack. No other validators will be evaluated and plain validators takes precedence over field validators meaning that they get evaluated in the order they are defined before field validators ...
