Question

我正在使用Jersey-Test-Framework编写RESTful Web服务测试。我的REST服务代码如下 -

package net.vsspl.mycontent.services;

import static org.junit.Assert.assertEquals;

import java.net.URISyntaxException;

import org.codehaus.jettison.json.JSONException;
import org.codehaus.jettison.json.JSONObject;
import org.junit.Test;

import com.sun.jersey.api.client.WebResource;
import com.sun.jersey.test.framework.AppDescriptor;
import com.sun.jersey.test.framework.JerseyTest;
import com.sun.jersey.test.framework.WebAppDescriptor;



public class LabelAPITest extends JerseyTest {

@Override
protected AppDescriptor configure() {
    return new WebAppDescriptor.Builder().build();
}

@Test
public void testGetAction() throws JSONException,
        URISyntaxException {
    WebResource webResource = client().resource("http://localhost:8080/Kalgudi").path("/rest/labels");
    JSONObject json = webResource.get(JSONObject.class);

    assertEquals("{\"labelId\":\"52529cb5e4b0c4219267eed2\",\"labelName\":\"Price Information\",\"labelDesc\":\"This is about a Price Information.\",\"parentLabelId\":\"0\",\"colourId\":\"524e5e5ae4b011a698175877\"}", 
                json.get("52529cb5e4b0c4219267eed2").toString());       
}

}

当我将其作为JUnit Test运行时，出现以下错误 -

我已经尝试过在pom.xml中使用不同的依赖项，例如 -

<dependency>
        <groupId>com.sun.jersey.jersey-test-framework</groupId>
        <artifactId>jersey-test-framework-core</artifactId>
        <version>1.8</version>
</dependency>

也

    <dependency>
          <groupId>com.sun.jersey.jersey-test-framework</groupId>
          <artifactId>jersey-test-framework-core</artifactId>
          <version>1.9</version>
          <scope>test</scope>
    </dependency>
    <dependency>
          <groupId>com.sun.jersey.jersey-test-framework</groupId>
          <artifactId>jersey-test-framework-external</artifactId>
          <version>1.9</version>
    </dependency>

和

    <dependency>
        <groupId>com.sun.jersey.jersey-test-framework</groupId>
        <artifactId>jersey-test-framework-grizzly2</artifactId>
        <version>1.18.1</version>
        <scope>test</scope>
    </dependency>

但他们都没有工作。每次都得到同样的错误。任何人都可以帮助我。

使用这3个依赖项，你的代码可以正常工作，删除Maven创建的默认junit依赖项。（只保留3个依赖项）
