proxy-classes

问题 today I ran into this problem which really bugs me, as almost the code already worked (and stopped working even after reverting to the older version). I'm accessing a Spring-Bean on a Facelets-Page. Spring wraps these objects in Proxies to use aspects and some other stuff. The problem is, that I get an exception when trying to access the property of a bean. The exception is something like this: javax.el.PropertyNotFoundException: /customers.xhtml @23,27 value="#{customerBean.customer}":

问题 I would like to ask is there a library which allows to generate implementation of interface at runtime with some additional features illustrated below. Let's say I have interface like that: interface ICustomer { string Name {get;set;} string IAddress { get;set; } } interface IAddress { string Street {get;set;} } I would like to do something like that: ICustomer customer = someLibrary.Create<ICustomer>(bool createSubObjects) where Create<T>() method would create an implementation like this at

问题 I have an interface as Iface that has two methods written in java. That interface is an inner interface of Zzz class. I have written the invocation handler in scala. Then I tried to create a new proxy instance in scala like below. val handler = new ProxyInvocationHandler // this handler implements //InvocationHandler interface val impl = Proxy.newProxyInstance( Class.forName(classOf[Iface].getName).getClassLoader(), Class.forName(classOf[Iface].getName).getClasses, handler ).asInstanceOf

问题 I just created a proxy model and was surprised that manage.py makemigrations creates a new migration file with a migrations.CreateModel operation. A proxy model does not create a new database table, it's just a different python interface to the same dataset and indeed manage.py sqlmigrate my_app_label 0042 returns nothing. I thought that it might be used to create the proxy model ContentType but those are created on demand if they don't exist. Is it used to trigger the creation of the proxy

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . When creating a proxy with for example cglib or javassist proxies, this proxy is implemented by creating a subclass of the proxy target. However, this means that the annotations on this proxy are lost. This is problematic when a class is processed by two libraries where: The first libraries requires the creation

问题 I need to implement a simple PHP proxy in a web application I am building (Its flash based and the destination service provider doesn't allow edits to their crossdomain.xml file) Can any php gurus offer advice on the following 2 options? Also, I think, but am not sure, that I need to include some header info as well. Thanks for any feedback! option1 $url = $_GET['path']; readfile($path); option2 $content .= file_get_contents($_GET['path']); if ($content !== false) { echo($content); } else { /

问题 Thanks in advance for your help. Inside mi project I have an app involving models that were generated from an existing database. As those tables are administered by a DBA, they are kept as unmanaged models. As it is possible that we require to re-generate the models from db due to changes in the schema, we have created alternative proxy models for each of those models to decouple the part that we manage from what we don't. Below you can see an example based on our current layout. The example

问题 What do it wants from me? How to make it work? var proxy_handler = { ownKeys: function(target) { return Object.keys(target.data) }, } var proxxxy = function(initial_data) { var return_value = "Goodbye world" var target = function() { return return_value } if(typeof initial_data == "undefined") { target.data = {} } else { target.data = initial_data } return new Proxy(target, proxy_handler) } var p = proxxxy({q:"aaa",w:"bbb",f:"ccc"}) console.log(p()) console.log(Object.getOwnPropertyNames(p))

问题 What is the best way to implement an interface that combines some instances of the same interface in various specified ways? I need to do this for multiple interfaces and I want to minimize the boilerplate and still achieve good efficiency, because I need this for a critical production system. Here is a sketch of the problem. Abstractly, I have a generic combiner class which takes the instances and specify the various combinators: class Combiner<I> { I[] instances; <T> T combineSomeWay

问题 When spring creates a proxy, it uses cglib with default naming policy. Is there any way to change the naming policy? Generated class names clash with another framework I use. 回答1: It seems cglib claims it can detect name clashes but for some reason it does not in this case. Because of that problem (and your report?) the other framework you are using (catch-exception) patched their code to avoid it. 来源： https://stackoverflow.com/questions/19741285/spring-how-to-change-cglib-naming-policy
