annotations

问题 How can I create an annotation, such as @DateOutput that is equivalent with another Jackson annotation, such as: @JsonFormat(shape=JsonFormat.Shape.STRING, pattern="yyyy-MM-dd'T'HH:mm:ss.SSSZ", timezone="UTC") Or ideally, to a set of annotations, such as @JsonSerialize(using = XSerializer.class) @JsonDeserialize(using = XDeserializer.class) 回答1: You can use @JacksonAnnotationsInside as a annotation container like follows: @Retention(RetentionPolicy.RUNTIME) @Target({ElementType.FIELD,

问题 Short: I have a project that provides a war artifact which includes a servlet with annotations but no web.xml.

Long story: My servlets look like this package swa; import java.io.IOException; import java.io.PrintWriter; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet

问题 Maybe a dumb question, but it would be nice if there was a way to hide or collapse Java annotations when viewing source in Netbeans (or Eclipse). I'm not finding an option and a quick search didn't turn anything up. Is this one of those "you should never want to do that, code folding is a sin!" things? Personally I'd find it useful for annotated entity classes. All the hibernate / etc annotations are just fluff that I never look at once my mapping is working fine. It's similar to imports,

问题 I use the following annotation to call a stateless session bean once a 5 minutes: @Schedule(second = "0", minute = "0/5", hour = "*") I works as expected, except it stops itself after a few days. I guess there may be a default lifetime and I do not know how to override it. Please help me to configure the scheduler to run indefinitely. 回答1: to know if there is expiration date for your object you can use getTimers() to return an object of that timer then use this method getTimeRemaining() to

问题 I am using plain vanilla JAXRS in a provided Application Server with Swagger 1.5.18. I can get the Swagger annotated classes to appear in the swagger.json , but I am having trouble setting the Swagger to scan for non annotated classes, those with just the @Path JAXRS annotations. I currently have the BeanConfig in the Class that is extending Application . I tried using a Servlet that extended DefaultJaxrsConfig with @WebInitParam(name="scan.all.resources", value="true") but that did not work
