问题 I'm trying to get CDI to work in my application, but I only get NullPointerExceptions when I do.

PlaylistRESTController.java import javax.inject.Inject; import javax.servlet.http.HttpServletRequest; import javax.ws.rs.*; import javax.ws.rs.core.*; @Path("/api

问题 I am working on angular2 I have created service and inject those service using @Inject in component. I am confuse with the use of @Injectable() in service itself and what diff it makes. 回答1: @Inject() is a manual mechanism for letting Angular 2 know that a parameter needs to be injected @Injectable() lets Angular 2 know that a class can be used with the dependency injector. @Injectable() is not strictly required if the class has other Angular 2 decorators on it. What is important is that any

My question, say I have a table which contains model records, how can I build that table with JS, i.e pass the objects into javascript rather then straight build the table in template? so far from searching the only way I've found is things like this: var data = '{{data}}'; {{data}} could be json for this example. which seems ugly and bad to me, to put template code in javascript, and also I don't like the
