requires a plug-in to the intrusion detection program into the Java Web application, so that every time users visit the Java Web, the first to the intrusion detection program to report to the rules to release. There are roughly two types of Java

Approximate idea Inherit HttpServlet, implement Dispatcherservlet, intercept all requests; Dispatchservlet rewrite the init () method, which is responsible for initializing the framework; Rewrite the service () method to get HttpServletRequest, httpservletresponse; Through the HttpServletRequest, the HttpServletResponse, obtains the request path, the request parameter, carries on the request processing, and does the forwarding or redirec

The structs can be automatically encapsulated for parameters, which is also simple.One, the action parameter is automatically encapsulated:1, you can declare properties of public, accept parameters directly in the action class.2, the attribute is also private, if it is private, you need to provide a setter method, you can also provide getter method as needed.3,struts can automatically convert types, typically we pass string-type arguments, and struts can be converted to the default declared vari

and a single file upload configuration is the same, just accept the parameter in the action, accept the array, is no longer a single file.One, the action implementation:public class Mutablefilesupload extends Actionsupport {private static final long Serialversionuid = 1l;public file[] Uploa Dobjects;public string[] uploadobjectsfilename;public string[] uploadobjectscontenttype;public String moreInfo; Public String upload () {System.out.println (moreinfo);//1.

1, a reference to the configuration fileThere can be more than one configuration file in struts, and a struts profile can be set up in each module's package.The main configuration file, placed in the "src" folder, can introduce other profiles, introduced in the way:Where the configuration path of the file property can be right-click, copy qualified name2, configuration of common constantsSpecify the request encoding formatSpecifies the URL suffix name of the accessSome other 　　3, package conf
