问题 Let's say that I have this class: @Singleton public class Parent { ... } and this class: public class Child extends Parent { ... } in my Java app, and my app relies on Guice injection to create objects. If I create an instance of Child through Injector.createInstance(Child.class) , wiill that instance be a Singleton automatically (because the parent was annotated as a Singleton), or do I need to explicitly add the @Singleton annotation to Child ? 回答1: Nope - you'd need to annotate Child as

问题 Consider the following code <?php // warning: this code is unsafe and for demonstrational purposes only, // do not use in a production environment $filename = $_GET['filename']; $extension = 'txt'; $path = '/absolute/path'; $fullFilename = sprintf('%s/%s.%s', $path, $filename, $extension); echo file_get_contents($fullFilename); We all know (at least I hope so) that prepending an absolute path is by no way an adequate mean to prevent leaving the given path - one can simply insert one or more "

问题 I'm doing an exercise on the SQL Injection, the query is given. The data comes in between ''. So this is the query: select * from contacts where name = '' I managed to see the users in the table using this: select * from contacts where name = 'anything' or 1='1' But my question is how I can write it so that I can write a new query? Or see the database name for example so that I can check other tables. EDIT: To avoid confusion the query is not given to us, there is a textfield on a webpage,

问题 What's the difference between interface interception and constructor Injection in asp.net unity? I am lack of understanding DI with Unity I am working on an old project and in unity.config, some like this, <register type="ICRIC2012TrialUserService" mapTo="CRIC2012TrialUserService"> <lifetime type="perthread"/> <interceptor type="InterfaceInterceptor"/> <policyInjection/> </register> but some do not have <interceptor type="InterfaceInterceptor"/> but in project these class and interface work

问题 Here is the problem, I have code being generated by Deferred Binding in GWT, and I would like to use Gin Injection inside of this code. Initially, I attempted to put a private constructor with an @Inject annotation in the generated class, but GWT complained that it did not have a public noargs constructor. In any case, I also got errors regarding my attempts to inject something abstract without bindings, and feel like I couldn't possibly bind it since I don't have the type literal available

问题 I need to hook managed (C#,C++/CLI) processes, I need to find and send information about how many windows it has(its associated controls and their properties)to the target application which is written in C# managed code. For that What I need to do? Do I need to explore IAT (Import Address Table) & EAT(Export address Table) of that managed process? Do I need to write injector DLL in C++? What else apart from changing IAT and EAT , do I need? [EDIT] I need to attach managed running processes to

问题 I'm using Windsor to do IoC in our .Net project, but I'm having difficulties doing setter injection in code. I believe it comes from the fact that I blanket register my components, since eventually I'm hoping that legacy project will be fully IoC compliant and mostly Unit Tested (sweet dreams!). Here is how I'm registering the DAOs: container .Register(AllTypes.FromAssemblyNamed("MyApp.Business") .Where(Component.IsInNamespace("MyApp.Business.Dao")) .WithService.DefaultInterface()); And here

问题 I am trying to inject code into the minecraft 1.8 jar using javassist. The insertBefore & insertAfter methods work perfectly fine. But the insert at method does not work as expected. I am getting this error: https://gist.github.com/czaarek99/dda36426318f331ce6b0 Here is the code that handles the injection: if (className.equals(mappingManager.getMapping(CommonMappings.MINECRAFT_CLASS))) { CtClass ctClass = classPool.get(mappingManager.getMapping(CommonMappings.MINECRAFT_CLASS, true)); /

问题 I want to run the jms tutorial files in eclipse. I have configured glassfish properly and added the jms resources. It works ok if I run it in netbeans. I created an "application client project" in eclipse. Here is where the resources get injected: @Resource(mappedName = "jms/ConnectionFactory") private static ConnectionFactory connectionFactory; @Resource(mappedName = "jms/Queue") private static Queue queue; @Resource(mappedName = "jms/Topic") private static Topic topic; Then, when it gets

问题 An HTML template is passed to Coldfusion. The head tag of the template has additional attribute: <head profile="http://abc.com"> The issue is that when generating the output based on this template Coldfusion injects its scripts inside the head tag: <head <script type="text/javascript" src="/CFIDE/scripts/cfform.js"></script> <script type="text/javascript" src="/CFIDE/scripts/masks.js"></script> profile="http://abc.com"> This causes profile="http://abc.com"> to appear on the top of the page
