我正在使用 Spring-Jersey3,但无法弄清楚如何使用 Spring bean 对 RESTFul API 进行单元测试
Controller
package com.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import com.service.DataSource;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
@Path("test")
@Component
public class SpringController {
@Autowired
private DataSource datasource;
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getHello() {
return new String(datasource.load());
}
}
服务接口(interface)
package com.service;
public interface DataSource {
public String load();
}
服务实现
package com.service;
import org.springframework.stereotype.Repository;
@Repository
public class DataSourceImpl implements DataSource {
@Override
public String load() {
return "Hello";
}
}
ResourceRegister.java(泽西资源寄存器)
package com.component;
import org.glassfish.jersey.server.ResourceConfig;
import com.controller.SpringController;
public class ResourceRegister extends ResourceConfig {
public ResourceRegister () {
register(SpringController.class);
}
}

单元测试<<--我真的不知道如何测试这个
public class test extends JerseyTest {
public test() {
super("com.service", "com.controller");
}
@Override
protected AppDescriptor configure() {
return new WebAppDescriptor.Builder("com.service","com.controller")
.contextParam("contextConfigLocation", "classpath:serviceContext.xml")
.contextPath("/rest")
.servletClass("org.glassfish.jersey.servlet.ServletContainer.class")
.initParam("javax.ws.rs.Application", "com.component.ResourceRegister")
.build();
}
@Test
public void test() {
Client client = new Client();
WebResource resource = client.resource("test");
ClientResponse response = resource.post(ClientResponse.class);
assertEquals(200, resposne.getStatus());
}
}
项目 Source Code
问题:依赖注入(inject)返回 null
最佳答案
我要解决的一些问题:
Client
你自己。创建了一个,我们可以简单地调用JerseyTest
的target(String path)
取回 WebTarget
的方法(泽西 2.x,WebResource
是泽西 1.x)这是一个有效的重构。
依赖项(我只添加了这个依赖项,并没有删除任何内容,因为您的 GitHub 项目不包含任何与测试相关的内容,就像您上面的代码示例一样)
<dependency>
<groupId>org.glassfish.jersey.test-framework.providers</groupId>
<artifactId>jersey-test-framework-provider-grizzly2</artifactId>
<version>2.15</version>
</dependency>
测试
import com.component.ResourceRegister;
import org.glassfish.jersey.servlet.ServletContainer;
import org.glassfish.jersey.test.DeploymentContext;
import org.glassfish.jersey.test.JerseyTest;
import org.glassfish.jersey.test.ServletDeploymentContext;
import org.glassfish.jersey.test.grizzly.GrizzlyWebTestContainerFactory;
import org.glassfish.jersey.test.spi.TestContainerFactory;
import org.junit.Assert;
import org.junit.Test;
import org.springframework.web.context.ContextLoaderListener;
public class SpringTest extends JerseyTest {
@Override
protected TestContainerFactory getTestContainerFactory() {
return new GrizzlyWebTestContainerFactory();
}
@Override
protected DeploymentContext configureDeployment(){
return ServletDeploymentContext
.forServlet(new ServletContainer(new ResourceRegister()))
.addListener(ContextLoaderListener.class)
.contextParam("contextConfigLocation", "classpath:applicationContext.xml")
.build();
}
@Test
public void test() {
String response = target("test").request().get(String.class);
Assert.assertEquals("Hello", response);
System.out.println(response);
}
}
对于那些不使用 xml 上下文文件的人,您可以使用注释配置应用程序上下文,并将其添加为 init 参数
return ServletDeploymentContext
.forServlet(new ServletContainer(new ResourceRegister()))
.addListener(ContextLoaderListener.class)
.initParam("contextConfig", new AnnotationConfigApplicationContext(YourSpringConfig.class))
.build();

更新
所以经过几次测试后,我发现了一些有趣的事情
一:
有了上面的依赖,即使我们不配置
DeploymentContext
, 并覆盖 Application configure()
在 JerseyTest
,它仍然可以工作。无法真正解释它,但似乎描述符仍然被拾取。import javax.ws.rs.core.Application;
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.test.JerseyTest;
import org.junit.Assert;
import org.junit.Test;
public class SpringTest extends JerseyTest {
@Override
public Application configure() {
return new ResourceConfig().packages("com.controller");
}
@Test
public void test() {
String response = target("test").request().get(String.class);
Assert.assertEquals("Hello", response);
System.out.println(response);
}
}
二:
即使我们摆脱了上述依赖(grizzly)并使用内存中的依赖,同样简单的先前测试仍然有效。该文件指出
In-Memory container is not a real container. It starts Jersey application and directly calls internal APIs to handle request created by client provided by test framework. There is no network communication involved. This containers does not support servlet and other container dependent features, but it is a perfect choice for simple unit tests.
所以我不完全确定他们指的是什么 Servlet 功能,因为这个测试仍然有效
<dependency>
<groupId>org.glassfish.jersey.test-framework.providers</groupId>
<artifactId>jersey-test-framework-provider-inmemory</artifactId>
<version>2.15</version>
</dependency>
我特别不明白的是这个声明
"There is no network communication involved"
因为当我运行测试时,我看到了一个日志
INFO: Creating InMemoryTestContainer configured at the base URI http://localhost:9998/
