从另一个Jersey资源类调用1泽西资源类与@Context ServletContext [英] Call 1 jersey resource class from another Jersey resource class with @Context ServletContext
问题描述
我有Jersey资源类A调用资源类B中的方法。这两个类在类级别有一个@Context ServletContext servletContext。当我实例化B类使用它的空构造函数从资源类A调用它时,servletContext在调用的B类方法中为null。有没有任何Jersey框架方法我可以调用类B,但有servletContext保留其值/属性从A类。
I have Jersey resource class A calling a method in resource class B.Both classes have a @Context ServletContext servletContext at the class level. When I instantiate class B to call it from resource class A using its empty constructor, servletContext is null in the class B method being called. Is there any Jersey framework way I can call class B and yet have the servletContext retain its values/attributes from class A.
推荐答案
您可以使用ResourceContext实例化B类。也就是说在A类中你可以有:
You can instantiate class B using ResourceContext. I.e. in class A you can have:
@Context private ResourceContext rc;
然后在你可以实例化资源B如下:
And then in you can instantiate resource B as follows:
B resourceB = rc.getResource(B.class);
请参阅 ResourceContext javadoc 了解更多信息。
