JAX-RS Jersey/Grizzly定义接口资源 [英] JAX-RS Jersey/Grizzly Define an interface resource

问题描述

以下示例为此处在部署示例时使用Grizzly容器的资源. 它使用定义为类的资源，而不是我想用批注定义一个接口，并让资源类实现该接口.

Following the example here On deploying a sample resource using the Grizzly container. It uses a resource that is defined as a class, instead I would like to define an interface with the annotations and have the resource class implements that interface.

现在的问题是，灰熊抱怨找不到资源:

The problem now is that Grizzly complains that it can't find the resource:

com.sun.jersey.api.container.ContainerException: The ResourceConfig instance does not     contain any root resource classes.

在Main类上，其中"com.mycompany.pack"是包含实现类的软件包:

On Main class, where "com.mycompany.pack" is the package containing the implementation class:

final String baseUri = "http://localhost:9999/";
final Map<String, String> initParams = new HashMap<String, String>();
initParams.put("com.sun.jersey.config.property.packages", "com.mycompany.pack");

:但是，当在类上添加注释时，也可以使用. 如果有一种方法可以仅在接口级别声明注释.

: It works however when adding the annotations on the class as well. If there is a way to have the annotations declared only at the interface level.

推荐答案

您无法通过程序包扫描来完成此操作，因为它只会查找带有JAX-RS批注的类.您必须使用不同的方法:配置选项，可让您显式声明资源类，也可以使用球衣弹簧来管理您的实例.使用jersey-spring，不需要任何额外的步骤就可以使用您想要的界面.您只需注释接口，使实现成为Spring bean，它就可以工作.

You can't do it with package scanning because that only looks for classes with the JAX-RS annotations on them. You'll have to use a different approach: either one of the configuration options mentioned in the Jersey user guide that lets you explicitly declare your resource classes, or you could also use jersey-spring to manage your instances. With jersey-spring, there are no extra steps to be able to use an interface like you want to. You just annotate the interface, make the implementation a Spring bean, and it works.
