Question

以下是资源类示例：

@Path("/resource") 
public class SomeResource { 
    @GET 
    @Produces({MediaType.APPLICATION_XML}) 
    public String someMethod(@QueryParam("param1") String param1, ..., @Context HttpServletRequest request) { 
            String remoteUser = request.getRemoteAddr(); 
            // Business logic here. 
            return response; 
    } 
}

资源的JerseyTest：

public class TestSomeResource extends JerseyTest    { 
    @Override 
    protected Application configure() { 
            enable(TestProperties.LOG_TRAFFIC); 
            return new ResourceConfig(SomeResource.class); 
    } 

    @Test 
    public void testXMLResponse()   { 
            String response = target("resource") 
                            .queryParam("param1", param1) 
                            // More parameters here. 
                            .request() 
                            .accept(MediaType.APPLICATION_XML) 
                            .get(String.class); 
            // Some assertions on response. 
    } 
}

除了使用@Context HttpServletRequest作为输入参数的资源外，我能够为所有其他资源运行泽西测试。它给出InternalServerErrorException: HTTP 500 Internal Server Error.

Answer 1

您的例外情况与HttpServletRequest为null。

的事实有关

泽西岛文件说：

3.6。使用@Context

前面的部分介绍了@Context的用法。第5章   JAX-RS规范提供了所有标准的JAX-RS Java类型   可以与@Context一起使用。

使用servlet部署JAX-RS 应用程序然后使用ServletConfig，   ServletContext，HttpServletRequest和HttpServletResponse都是   可以使用@Context。

我猜你使用的jersey-test-framework-provider-grizzly2不支持它。

如果您想要访问HttpServletResponse，请删除该依赖项并添加：

<dependency>
    <groupId>org.glassfish.jersey.test-framework</groupId>
    <artifactId>jersey-test-framework-core</artifactId>
    <version>2.1</version>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-grizzly2-servlet</artifactId>
    <version>2.1</version>
</dependency>

现在你真的想告诉JerseyTest启动正确的测试服务器，为此你必须覆盖方法protected TestContainerFactory getTestContainerFactory()。 请务必将<your-java-package>替换为套餐的实际名称。

@Override
protected TestContainerFactory getTestContainerFactory() throws TestContainerException {
    return new TestContainerFactory() {
        @Override
        public TestContainer create(final URI baseUri, final ApplicationHandler application) throws IllegalArgumentException {
            return new TestContainer() {
                private HttpServer server;

                @Override
                public ClientConfig getClientConfig() {
                    return null;
                }

                @Override
                public URI getBaseUri() {
                    return baseUri;
                }

                @Override
                public void start() {
                    try {
                        this.server = GrizzlyWebContainerFactory.create(
                                baseUri, Collections.singletonMap("jersey.config.server.provider.packages", "<your-java-package>")
                        );
                    } catch (ProcessingException e) {
                        throw new TestContainerException(e);
                    } catch (IOException e) {
                        throw new TestContainerException(e);
                    }
                }

                @Override
                public void stop() {
                    this.server.stop();
                }
            };

        }
    };
}

您还可以查看org.glassfish.jersey.test.grizzly.GrizzlyTestContainerFactory以更好地实施工厂。

Answer 2

您还可以在configure方法中注入模拟的HttpServletRequest对象。这是泽西1的例子：

public abstract class AbstractIntegrationTest extends AbstractJerseyTest {

    protected HttpServletRequest httpServletRequest;

    @Override
    protected void configure(final ResourceConfig config) throws Exception {
        // create a mock and inject it via singleton provider
        httpServletRequest = mock(HttpServletRequest.class);
        config.getSingletons().add(
                new SingletonTypeInjectableProvider<Context, HttpServletRequest>(
                        HttpServletRequest.class, httpServletRequest) {});
    }

}

泽西岛2：

final HttpServletRequest request = mock(HttpServletRequest.class);
resourceConfig.register(new AbstractBinder() {
                            @Override
                            protected void configure() {
                                bind(request).to(HttpServletRequest.class);
                            }
                        });

Answer 3

所以最后我得到了解决方案（它接近最流行的答案，但变化很小）：

的pom.xml

<properties>    
  <jersey.version>2.22.1</jersey.version>
</properties>

    <dependency>
        <groupId>org.glassfish.jersey.test-framework.providers</groupId>
        <artifactId>jersey-test-framework-provider-inmemory</artifactId>
        <version>${jersey.version}</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.glassfish.jersey.containers</groupId>
        <artifactId>jersey-container-grizzly2-servlet</artifactId>
        <version>${jersey.version}</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>
        <scope>provided</scope>
    </dependency>

将以下抽象类添加到应用程序：

import org.glassfish.grizzly.http.server.HttpServer;
import org.glassfish.jersey.client.ClientConfig;
import org.glassfish.jersey.grizzly2.servlet.GrizzlyWebContainerFactory;
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.server.ServerProperties;
import org.glassfish.jersey.test.DeploymentContext;
import org.glassfish.jersey.test.JerseyTest;
import org.glassfish.jersey.test.TestProperties;
import org.glassfish.jersey.test.spi.TestContainer;
import org.glassfish.jersey.test.spi.TestContainerException;
import org.glassfish.jersey.test.spi.TestContainerFactory;

import javax.ws.rs.ProcessingException;
import javax.ws.rs.core.Application;
import java.io.IOException;
import java.net.URI;
import java.util.Collections;

public abstract class RestTest extends JerseyTest {

    @Override
    protected Application configure() {
        enable(TestProperties.LOG_TRAFFIC);
        return new ResourceConfig();
    }

    abstract protected String getRestClassName();

    @Override
    protected TestContainerFactory getTestContainerFactory() throws TestContainerException {
        return new TestContainerFactory() {
            @Override
            public TestContainer create(URI baseUri, DeploymentContext deploymentContext) {
                return new TestContainer() {
                    private HttpServer server;

                    @Override
                    public ClientConfig getClientConfig() {
                        return null;
                    }

                    @Override
                    public URI getBaseUri() {
                        return baseUri;
                    }

                    @Override
                    public void start() {
                        try {
                            this.server = GrizzlyWebContainerFactory.create(
                                    baseUri, Collections.singletonMap(ServerProperties.PROVIDER_CLASSNAMES, getRestClassName())
                            );
                        } catch (ProcessingException | IOException e) {
                            throw new TestContainerException(e);
                        }
                    }

                    @Override
                    public void stop() {
                        this.server.shutdownNow();

                    }
                };
            }
        };
    }

}

要测试休息，你需要这样做：

import org.junit.Test;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import javax.ws.rs.client.Entity;
import javax.ws.rs.core.Response;
import java.io.IOException;
import java.net.URISyntaxException;
import java.nio.file.Files;
import java.nio.file.Paths;

import static org.junit.Assert.assertEquals;

public class YourRestTest extends RestTest {

    private static final Logger LOG = LoggerFactory.getLogger("TestLog");

    @Override
    protected String getRestClassName() {
        return "com.app.rest.YourRest";
    }


    @Test
    public void test() throws URISyntaxException, IOException {
        String ttt = new String(Files.readAllBytes(Paths.get(YourRestTest.class.getResource("/rest_resource/ttt.json").toURI())));
        Response response = target("/xxx").path("/yyyy").request().post(Entity.entity(ttt, "application/json"));
        assertEquals(Response.Status.OK.getStatusCode(), response.getStatus());
    }
}

（目前列出的解决方案都没有为我工作）

Answer 5

好像很久以前这个问题一直存在。作为@ lpiepiora的解释，我们需要一个基于Servlet的测试容器。并且jersey-test-framework-provider-grizzly2中已有一个（不知道发布的问题时是否存在），GrizzlyWebTestContainerFactory，并且它需要不同的{{} 1}}。拉出最新的git，你会在test-framework/providers/grizzly2/src/test/java/org/glassfish/jersey/test/grizzly/web/GrizzlyWebTest.java中找到一个例子。为了简单直接，您只需要在基础测试类中添加这些覆盖：

DeploymentContext

（将// --- For Servlet-based test container --- begins --- @Override protected DeploymentContext configureDeployment() { return ServletDeploymentContext.forServlet(new ServletContainer(new YourResourceConfig())).build(); } @Override protected TestContainerFactory getTestContainerFactory() throws TestContainerException { return new GrizzlyWebTestContainerFactory(); } // --- For Servlet-based test container --- ends --- // other stuff...替换为真实的。{/ p>

修改如果你使用泽西YourResourceConfig，你会发现上面的解决方案失败了，因为你没有所有的Spring bean。解决它：

jersey-spring3

Answer 6

我遇到了类似的问题，并通过测试容器工厂解决了。

test().catch(err => {
  // Handle the error in some way
  console.error(err)
})

Answer 7

更简单的方法是在测试构造函数中提供正确的工厂：

TestSomeResource() {
    super(new GrizzlyWebTestContainerFactory());
}

并提供servlet上下文：

@Override
protected DeploymentContext configureDeployment() {
    return ServletDeploymentContext.forPackages("...").build(); // or other builder method
}
