问题 Using Angular 4.3.1 and HttpClient, I need to modify the request and response by async service into the HttpInterceptor of httpClient, Example for modifying the request: export class UseAsyncServiceInterceptor implements HttpInterceptor { constructor( private asyncService: AsyncService) { } intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> { // input request of applyLogic, output is async elaboration on request this.asyncService.applyLogic(req).subscribe(

问题 I want to know if there is an interceptor in JSF (like we use in Spring), and how to do we implement it? 回答1: You could implement a PhaseListener for this. You could program them to listen on a specific JSF phase which you specify in the overridden getPhaseId() method. You can intercept on the before and after phase events by beforePhase() and afterPhase() methods. The below example listens on the render response phase: public class RequestInterceptor implements PhaseListener { @Override

问题 I am trying to create an Audit table that will ends looking something like that : entity,id,property,oldValue,newValue,user,timestamp using hibernate EmptyInterceptor I expect that this table will have a lot of IO's . It seems that previouseState at onFlushDirty method is not working as I expected . how can I get the old value without fetching it from the db as shown here ? I was trying to follow this post public class AuditLogInterceptor extends EmptyInterceptor { private Set inserts = new

问题 I want to add spring mvc interceptor as part of Java config. I already have a xml based config for this but I am trying to move to a Java config. For interceptors, I know that it can be done like this from the spring documentation- @EnableWebMvc @Configuration public class WebConfig extends WebMvcConfigurerAdapter { @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(new LocaleInterceptor()); } } But my interceptor is using a spring bean autowired

问题 I am trying to use an Interceptor to restrict users from performing certain actions. ContainsKeyInterceptor : public class ContainsKeyInterceptor extends AbstractInterceptor implements SessionAware { private static final long serialVersionUID = 1L; private Map<String, Object> session; @Override public String intercept(ActionInvocation actionInvocation) throws Exception { if(session == null) { System.out.println("session is null"); } if(session.containsKey("currentId")) { return "index"; }

问题 I'm struggling a bit with understanding how rest interceptor annotations can add different values that are later visible in the filter. Given the code below I would expect that once in the filter the permissions values would have foo and bar in them, however they are empty. Any help would be greatly appreciated. Annotation package edu.psu.swe.fortress.poc.interceptor; import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy;

问题 I want add a response interceptor to my $http service for error handling purposes. The interceptor logic include send errors messages to server using $http in case necessary, BUT I don't want send errors messages to the server about errors messages, I mean, I want disable my interceptor while sending error message to the server. My idea was create a service named 'remote_log' and put inside it all the code needed to send error to server. That service of course will use the $http service and

问题 I trying to build an UI to view the SOAP transactions that were sent out from my application. A typical scenario is that each user transaction include multiple web-service request to multiple systems and I am generating a transactionId for that user transaction and Logging all the logs with that transactionId in log file, so that the log file can be searched using the transactionId and the corrosponding log statements can be displayed on UI. So, I am able to append the generated transactionId

问题 I have created a web application which uses Weld-2.2.0 CDI implementation and runs on Tomcat-7. I have created an interceptor to log method calls. But when i run the application, it bypasses interceptor and calls method directly. My interceptor constructs are as below: Interceptor Binding: @Inherited @InterceptorBinding @Retention(RUNTIME) @Target({METHOD, TYPE}) public @interface LogMe{ } Interceptor class: @LogMe @Interceptor public class LogInterceptorImpl { private static final Logger log

问题 The SysV ABI defines the C-level and assembly calling conventions for Linux. I would like to write a generic thunk that verifies that a function satisfied the ABI restrictions on callee preserved registers and (perhaps) tried to return a value. So given a target function like int foo(int, int) it's pretty easy3 to write such a thunk in assembly, something like 1 : foo_thunk: push rbp push rbx push r12 push r13 push r14 push r15 call foo cmp rbp, [rsp + 40] jne bad_rbp cmp rbx, [rsp + 32] jne
