如何将拦截器和筛选器应用于Weblogic 12c上的静态服务 [英] How to apply interceptors and filters to restful services on Weblogic 12c

问题描述

我了解到 Weblogic 12c v12.2.1 使用 Jersey 作为 JAX-RS 实施.因此，我按照此页面上的说明进行操作，但是我没有通过使用名称绑定或动态绑定(即上述链接中的更多信息)来声明拦截器

I understand that Weblogic 12c v12.2.1 uses Jersey as a JAX-RS implementation. So I followed the instructions on this page but I haven't succeeded to declare an interceptor whether by using name binding or dynamic binding (i.e. more info in the mentioned link)

我的应用程序正常运行，因为我实际上可以调用宁静的服务，但是我无法应用过滤器或拦截器，它们从未参与该过程.

My application is working normally because I can actually call the restful services, but I can't apply filters or interceptors, they are never involved in the process.

我根本没有编辑 web.xml ，我只有一个javax.ws.rs.core.Application子类

I didn't edit web.xml at all, all I have is an javax.ws.rs.core.Application child class

@ApplicationPath("rs")
public class MyApp extends Application {
    private Set<Object> singletons = new HashSet<Object>();
    private Set<Class<?>> empty = new HashSet<Class<?>>();

    public MyApp() {
        singletons.add(new MyService());
    }

    @Override
    public Set<Class<?>> getClasses() {
        return empty;
    }

    @Override
    public Set<Object> getSingletons() {
        return singletons;
    }
}

MyService类如下

MyService class looks like this

@Path("")
@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
public class MyService {
    private static final Logger log = Logger.getLogger(MyService.class);

    @GET
    @Path("login")
    public Status login(@QueryParam(USERNAME_PARAM) String username, @QueryParam(PASSWORD_PARAM) String password, @Context HttpServletRequest request) {
        return new Status(ServiceMessages.USER_AUTHENTICATION_SUCCESS);
    }

我有一个空的@Path值，因为我不能排除它，我已经在 MyApp 类中指定了我的路径，而且我也不想为此指定路径课.

I have an empty @Path value because I can't exclude it, I've already specified my path in MyApp class and I don't wan't to specify a path to this class.

我的绑定类

import javax.ws.rs.container.DynamicFeature;
import javax.ws.rs.container.ResourceInfo;
import javax.ws.rs.core.FeatureContext;

import com.mycompany.ws.filters.GZIPCompressor;
public class GzipDynamicBinder implements DynamicFeature {

    @Override
    public void configure(ResourceInfo resourceInfo, FeatureContext context) {
        context.register(GZIPCompressor.class);
    }

}

我的拦截器类

import java.io.IOException;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;

import javax.ws.rs.WebApplicationException;
import javax.ws.rs.ext.ReaderInterceptor;
import javax.ws.rs.ext.ReaderInterceptorContext;
import javax.ws.rs.ext.WriterInterceptor;
import javax.ws.rs.ext.WriterInterceptorContext;

public class GZIPCompressor implements WriterInterceptor, ReaderInterceptor {

    @Override
    public Object aroundReadFrom(ReaderInterceptorContext context) throws IOException, WebApplicationException {
        System.out.println(">>> Compression Reader <<<");
        context.setInputStream(new GZIPInputStream(context.getInputStream()));
        return context.proceed();
    }

    @Override
    public void aroundWriteTo(WriterInterceptorContext context) throws IOException, WebApplicationException {
        System.out.println(">>> Compressor Writer <<<");
        context.setOutputStream(new GZIPOutputStream(context.getOutputStream()));
        context.proceed();
    }

}

我很欣赏所有答案，但我真的很想与 web.xml 文件无关的答案.

I appreciate all answers, but I'd really like an answer that has nothing to do with the web.xml file.

推荐答案

1. Weblogic JAX-RS 版本是 1.1 (我在任何地方都找不到过滤器或拦截器的概念)
2. Weblogic Jersey 的版本是 1.17 ，目前我正在参考最新版本的文档，该文档的最新版本是 2.6 .

1. Weblogic JAX-RS version is 1.1 (I can't find the concept of Filters or Interceptors anywhere)
2. Weblogic Jersey version is 1.17, and I was referencing the documentations for the latest version, which is 2.6 at this time.
