get out cast

If you convert an object to an object, it will not change. If any other type of value is converted to an object, an instance of the built-in class StdClass will be created. If the value is NULL , the new instance is empty. Converting an array into an object causes the key name to be the property name and has a corresponding value. For any other value, a member variable named scalar will contain the value.$obj=(object)‘ciao‘;echo$obj->scalar;//outputs‘ciao‘?>PHP

First, I have a abstractservice parent class. The sub-class userservice inherits this parent class and does not write the userservice interface (iuserservice ). Then use the following in useraction: User u = (userservice) springutils. getbean ("userservice"). querybyusername (model ); User u = (userservice) getservice (). querybyusername (model ); $ Proxy x cannot be cast .... . Then I added the iuserservice interface, which implements iuserse

We have got this error lately with Apache Tomcat installation and our old applications written on Struts 2 and webwork 2. Org. Apache. xerces. parsers. xml11configuration cannot be cast to org.

causes the mistake. But some of the mistakes are very thin. For example, this. So write it down and hope not to do it again.First paste on the previous Baidu.This error is usually a type mismatch. What type of detail, depends on what data you are, query data from the database is garbled. But the database shows the normal utf-8, because of the use of nested queries, nested queries using the Chinese string concatenation. And then in Sparta, in fact, this error is very easy to avoid, because the t

Char *ptr; // then omit part of the code if ((int) ptr==-1 ) // wrong Place The meaning of the sentence is from void* to int conversion loss Precision, I believe see explanation some people understand,This problem only occurs on Linux with the X64 bit, because the pointer occupies 8 bytes on a 64-bit machine, and int occupies four bytes, so this problem occurs.Workaround:(long) ptr = =-1 just fine.About Linux under C compile error (warning) cast

Use the code on StackOverflow to describe the problem: Objectmapper mapper = new Objectmapper (); listThe conversion will not have an error, but it will throw an exception when getting the specific data:System.out.println (list.get (0)); System.out.println (List.get (0). Getforename ()); return list;There is very little exception information.Workaround:listJackson conversion Generic list error java.util.LinkedHashMap cannot be cast to com.xxx
