内省泽西资源模型泽西2.x. [英] Introspecting Jersey resource model Jersey 2.x

问题描述

我编写了自己的扫描程序来浏览我的JAX-RS资源，并使用 jersey-server-1.18.1 打印出方法名称和路径。问题是我将相同的代码迁移到2.16（将包名称从 com.sun。* 更改为 org.glassfish。* ），它不会起作用。

I have written my own scanner to go through my JAX-RS resources and print out the method names and paths using jersey-server-1.18.1. The problem is when I migrate my same code to 2.16 (changing the package names from com.sun.* to org.glassfish.*), It just won't work.

深入挖掘我发现那些必需 jersey-server 的课程并不公开。谁知道原因？如何将我的代码从1.x迁移到2.x？实际上没有关于此迁移的文档。

Digging deep I found that those required jersey-server classes are no long public. Anyone knows the reason why? And how can I migrate my code below from 1.x to 2.x ? There is literally no documentation on this migration.

所有帮助表示赞赏！下面的代码是1.x

All help appreciated! Below is the code with 1.x

推荐答案

Jersey 2.x的新API主要可以在 org.glassfish.jersey.server.model package。

The new APIs for Jersey 2.x, can mainly be found in the org.glassfish.jersey.server.model package.

我能想到的一些等价物：

Some equivalents I can think of:

• AbstractResource == 资源

• AbstractResource == Resource

IntrospectionModeller.createResource ==我相信 Resource.from（BaseResource.class）

AbstracResourceMethod == ResourceMethod

AbstracResourceMethod == ResourceMethod

res ource.getSubResourceMethods（） == getChildResources（），实际上只返回列表<资源>

resource.getSubResourceMethods() == getChildResources(), which actually just returns a List<Resource>

AbstractSubResourceLocator ==似乎不存在。我们只需检查上面的子资源，看看它是否是一个定位器

AbstractSubResourceLocator == Doesn't seem to exist. We would simply check the above child resource to see if it is a locator

for (Resource childResource: resource.getChildResources()) {
    if (childResource.getResourceLocator() != null) {
        ResourceMethod method = childResource.getResourceLocator();
        Class locatorType = method.getInvocable().getRawResponseType();
    }
}

这是我能够提出的，与你得到的相匹配。

Here's what I was able to come up with, to kind of match what you got.

import com.wordnik.swagger.annotations.ApiOperation;
import org.glassfish.jersey.server.model.Resource;
import org.glassfish.jersey.server.model.ResourceMethod;

public class ApiScanner {
    public static void main(String[] args) {
        ApiScanner scanner = new ApiScanner();
        scanner.xyz();
    }

    public void xyz() {
        Resource resource = Resource.from(BaseResource.class);
        abc(resource.getPath(), resource);
    }

    public void abc(String uriPrefix, Resource resource) {
        for (ResourceMethod resourceMethod: resource.getResourceMethods()) {
            String uri = uriPrefix;
            System.out.println("-- Resource Method --");
            System.out.println(resourceMethod.getHttpMethod() + "\t" + uri);
            ApiOperation api = resourceMethod.getInvocable().getDefinitionMethod()
                                                .getAnnotation(ApiOperation.class);
        }

        for (Resource childResource: resource.getChildResources()) {
            System.out.println("-- Child Resource --");
            System.out.println(childResource.getPath() + "\t" + childResource.getName());

            if (childResource.getResourceLocator() != null) {
                System.out.println("-- Sub-Resource Locator --");
                ResourceMethod method = childResource.getResourceLocator();
                Class locatorType = method.getInvocable().getRawResponseType();
                System.out.println(locatorType);
                Resource subResource = Resource.from(locatorType);
                abc(childResource.getPath(), subResource);        
            }
        }
    }
}
