java – 试图将过滤器添加到Grizzly Jersey应用程序的问题

我有这个服务器初始化类：

package magic.app.main;

import org.glassfish.grizzly.http.server.HttpServer;
import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory;
import org.glassfish.jersey.server.ResourceConfig;

import java.io.IOException;
import java.net.URI;

public class Main {
    public static final String BASE_URI = "http://localhost:4747/";

    public static void main(String[] args) throws IOException {
        /* SOME NON-RELEVANT CODE UP HERE */

        final ResourceConfig rc = new ResourceConfig();

        rc.packages("magic.app.resource");
        rc.register(magic.app.main.CorsSupportFilter.class);

        final HttpServer server = GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI),rc);

        /* SOME NON-RELEVANT CODE DOWN HERE */
    }
}

我试图在初始化类中注册的这个过滤器类：

package magic.app.main;

import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.ResponseBuilder;

import com.sun.jersey.spi.container.ContainerRequest;
import com.sun.jersey.spi.container.ContainerResponse;
import com.sun.jersey.spi.container.ContainerResponseFilter;

public class CorsSupportFilter implements ContainerResponseFilter {

    @Override
    public ContainerResponse filter(ContainerRequest req, ContainerResponse contResp) {

        ResponseBuilder resp = Response.fromResponse(contResp.getResponse());
        resp.header("Access-Control-Allow-Origin", Configuration.getHttpAllowOrigin())
            .header("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS");

        String reqHead = req.getHeaderValue("Access-Control-Request-Headers");

        if(null != reqHead && !reqHead.equals(null)){
            resp.header("Access-Control-Allow-Headers", reqHead);
        }

        contResp.setResponse(resp.build());
        return contResp;
    }

}

当我运行应用程序时,我得到这块日志：

WARNING: A provider magic.app.main.CorsSupportFilter registered in SERVER runtime does not implement any provider interfaces applicable in the SERVER runtime. Due to constraint configuration problems the provider magic.app.main.CorsSupportFilter will be ignored.

我正在使用gradle,这是我的应用程序的Gradle构建文件：

apply plugin: 'java'

repositories{
    mavenCentral()
}

dependencies{
    // IP2C
    compile fileTree(dir: 'libs', include: '*.jar')

    // Jersey + Grizzly
    compile 'org.glassfish.jersey:jersey-bom:2.4.1'
    compile 'org.glassfish.jersey.containers:jersey-container-grizzly2-http:2.4.1'

    // Jersey
    compile 'com.sun.jersey:jersey-core:1.17.1'
    compile 'com.sun.jersey:jersey-server:1.17.1'

    // JSON
    compile 'org.codehaus.jackson:jackson-core-asl:1.9.13'
    compile 'org.codehaus.jackson:jackson-mapper-asl:1.9.13'
    compile 'org.codehaus.jackson:jackson-xc:1.9.13'
    compile 'com.googlecode.json-simple:json-simple:1.1.1'

    // Jersey + JSON
    compile 'com.sun.jersey:jersey-json:1.17.1'
    compile 'com.fasterxml.jackson.jaxrs:jackson-jaxrs-json-provider:2.3.0-rc1'

    // Postgres
    compile 'com.jolbox:bonecp:0.8.0.RELEASE'
    compile 'postgresql:postgresql:9.1-901-1.jdbc4'

    // Mail
    compile 'javax.mail:mail:1.5.0-b01'
}

解决方法:

你在你的应用程序中混合了两个版本的Jersey(1.x和2.x).在您的Main类中,您使用的是Jersey 2.x(包前缀是org.glassfish.jersey),而ContainerResponseFilter是Jersey 1.x专有API的实现.

如果你想使用Jersey 2.x,过滤器应该从JAX-RS 2.0实现ContainerResponseFilter.

如果您想坚持使用Jersey 1.x,您应该更改Main类中的注册(并且还使用来自Jersey 1.x的grizzly容器模块)：

final ResourceConfig rc = new PackagesResourceConfig("magic.app.resource");
rc.getContainerResponseFilters().add(CorsSupportFilter.class);
