Jax RS＆amp;泽西与朱尼特;测试用例被忽略

标签： eclipse maven junit jersey jax-rs

我无法让泽西岛与Junit合作。有人可以帮忙吗？我不知道还能做什么。

我正在使用我的tomcat服务器，当我运行项目时，我右键单击该文件夹并选择＆＃34;在服务器上运行。＆＃34;完成此操作后，我可以在我的Web浏览器中使用post-client来使用Web服务并且它可以正常工作。我不能让它与JUnit交互。 似乎无法找到网址，但我发誓，当我去发布客户端时，它会发挥作用。 我期望的网址是：

http://localhost:8080/propsub/webapi/new/getit

当我尝试在我的tomcast服务器停止运行我的测试用例时，我得到的警告+输出：

Feb 01, 2018 3:30:31 PM org.glassfish.jersey.test.JerseyTest getDefaultTestContainerFactory

以下是我的服务器 时的输出：

这是我的Junit课程：

package com.liron.test;

import static org.junit.Assert.*;

import java.net.URI;

import javax.ws.rs.client.Entity;
import javax.ws.rs.core.Application;
import javax.ws.rs.core.Response;
import javax.ws.rs.ext.Provider;
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.test.JerseyTest;
import org.glassfish.jersey.test.TestProperties;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;
import com.liron.pojo.error.ErrorMsg;

public class TestCases extends JerseyTest{
    @Override
    public Application configure() {
       enable(TestProperties.LOG_TRAFFIC);
        enable(TestProperties.DUMP_ENTITY);
        return new ResourceConfig(TestCases.class);
    }
    @BeforeClass
    public static void setUpBeforeClass() throws Exception{
    }

    @Before
    public void setUp() throws Exception{
        super.setUp();
    }
    @Override
    public URI getBaseUri() {
        return URI.create("http://localhost:8080/");
    }
     @Test  
        public void testParseException() {
         System.out.println("begin test case");
         String json = "{\"test\":\"val\".}";
         //Response output = target("propsub/webapi/new/getit").request().buildPost(Entity.json("hey")).invoke();
         //String output = target("/getit").request().post(Entity.json(json), String.class);
         Response output = target("/propsub/webapi/new/getit").request().post(Entity.json("hey"));
          //System.out.println(output.getStatus());
           // assertEquals("should return status 200", "200", output.getStatus());
            //assertNotNull("Should return list", output.getEntity());
           String x = output.readEntity(String.class);
            System.out.println("end : " + output.getStatus() + " x: " + x);
        }
}

这是api：

package com.liron.webserv;

import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

import javax.ws.rs.core.Response;

import com.liron.pojo.error.ErrorMsg;

import javax.ws.rs.core.Response.Status;
import javax.ws.rs.ext.ExceptionMapper;
import javax.ws.rs.ext.Provider;
/**

 */
@Path("/new")
public class New {

    /**
     * Method handling HTTP GET requests. The returned object will be sent
     * to the client as "text/plain" media type.
     *
     * @return String that will be returned as a text/plain response.
     */
    @Path("/getit")
    @POST
    @Produces(MediaType.APPLICATION_JSON)
    @Consumes(MediaType.APPLICATION_JSON)
    public Response getIt(String s) {
         System.out.println("begin getit");
        return Response.status(Status.NOT_IMPLEMENTED)
                 .entity(new ErrorMsg("414","Testtesttest"))
                 .build();

    }
}

这是ErrorMsg pojo 

package com.liron.pojo.error;

public class ErrorMsg{

    String errorCode;
    String errorMessage;

    public ErrorMsg(String code, String msg){
        setErrorCode(code);
        setErrorMessage(msg);
    }
    public String getErrorCode(){
        return errorCode;
    }

    public void setErrorCode(String errorCode){
        this.errorCode = errorCode;
    }

    public String getErrorMessage(){
        return errorMessage;
    }

    public void setErrorMessage(String errorMessage){
        this.errorMessage = errorMessage;
    }
}

应用程序配置：

package com.liron.config;
import java.util.HashMap;
import java.util.Map;

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("/api")
public class ApplicationConfig extends Application {

    @Override
    public Map<String, Object> getProperties() {
        System.out.println("begin getProperties");
        Map<String, Object> properties = new HashMap<String, Object>();
        properties.put("jersey.config.server.provider.packages", "com.memorynotfound.rs");
        System.out.println("end getProperties");
        return properties;
    }
}

编辑更新1 更改我的测试用例后的新输出包括：

public class TestCases extends JerseyTest{
    @Override
    public Application configure() {
        enable(TestProperties.LOG_TRAFFIC);
        enable(TestProperties.DUMP_ENTITY);
        //return new ResourceConfig(TestCases.class);
        return new ApplicationConfig();
       //return new ResourceConfig().register(New.class);
    }

输出：

begin getProperties
end getProperties

答案 0 :(得分：0)

return new ResourceConfig(TestCases.class);

这没有任何作用。您应该使用ResourceConfig注册资源类。该测试未检测到已注册的任何资源类，因此它不会运行。

如果你想使用ApplicationConfig，那就回去吧，因为它正在使用属性扫描软件包

@Override
public Application configure() {
   enable(TestProperties.LOG_TRAFFIC);
   enable(TestProperties.DUMP_ENTITY);
   return new ApplicationConfig();
}

顺便说一句，只需在您计划测试的资源上注册即可。例如

@Override
public Application configure() {
   return new ResourceConfig()
       .register(ResourceUnderTest.class);
}

这样做的一个好处是，此测试的成功与其他任何正确初始化资源无关。

除此之外，通常在Jersey应用程序中，您应该扩展Application，而不是扩展ResourceConfig。而不是使用getProperties，您只需拨打property中的ResourceConfig或只需致电packages即可设置包裹扫描。

@ApplicationPath("/")
public class ApplicationConfig extends ResourceConfig {
    public ApplicationConfig() {
        packages("you.package.to.scan");
    }
}

另一方面，如果您使用这种Java风格的配置，则不需要web.xml。
