我在 JerseyTest 和 Spring 上遇到了困难。以前在非 Spring Java 项目中，我通常为我的 REST API 做的是从 JerseyTest 扩展我的测试，模拟服务类并简单地（单元）测试我的 REST API。现在我在我的项目中使用 spring，在我的 REST 资源类中，服务使用@Autowired 进行注释。现在我正在使用相同的场景。Spring 介入并唠叨诸如缺少 applicationcontext.xml 之类的东西。我确实想在我的生产中使用 spring，但是对于我的单元测试，我不需要我的测试知道任何关于 Spring 及其所有自动装配和类路径注释处理的知识！我怎样才能做到这一点？这些类看起来像这样：

public class RESTResource{
  @Autowired
  MyService service;

  @GET
  public Response getSomeStuff(){
    ...
    service.getStuff()
  }

}

这是测试类

public class RESTResourceTest extends JerseyTest{

   private Service service;
   @Override
   public Application configure(){
      RESTResource resource = new RESTResource();
      service = Mockito.mock(Service.class);
      resource.setService(service);
      ResourceConfig config = new ResourceConfig();

      config.register(resource);
      return config;
   }
}

这是堆栈跟踪：

您可以做的是使用用于测试阶段的 sure-fire 插件简单地排除 jersey-spring3。

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <configuration>
                    <classpathDependencyExcludes>
                        <classpathDependencyExclude>
                            org.glassfish.jersey.ext:jersey-spring3
                        </classpathDependencyExclude>
                    </classpathDependencyExcludes>
                </configuration>
            </plugin>

以下是一些可能对您有所帮助的代码片段： 选项 1. 您的 REST 资源类：

@Component
@Path("/api/helloworld")
public class RESTResource{
@Autowired
MyService service;

@GET
@Produces(MediaType.TEXT_PLAIN)
public String helloMessage() {
    return "Hello World Jersey Way!";
}

}

  1. 您的测试配置类：

    @Component
public class JerseyConfig extends ResourceConfig {

/**
 * In constructor we can define Jersey Resources &amp; Other Components
*/
public JerseyConfig() {
    register(RESTResource.class);
}
}

3.你的测试基类：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)//NOTE : Application is a spring boot main class,or if you have specific configuration class similar to test config class above use @ContextConfiguration(classes = MyServiceSpringConfig.class) 
public class RESTResourceTest extends JerseyTest {

@Override
protected Application configure() {
    return new JerseyConfig();
}

@Test
public void contextLoads() {
}

@Test
public void someTest() throws Exception {
    // Very useful test
}


}

选项 2：

@Priority(value = 1)
public class MySpringWebInitializer implements WebApplicationInitializer
{
    @Override
    public void onStartup(ServletContext container)
    {
        //Tell jersey-spring3 the context is already initialized
        container.setInitParameter("contextConfigLocation", "NOTNULL");
        AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext();
        appContext.register(RESTResource.class);
        container.addListener(new ContextLoaderListener(appContext));
    }
}

此外，对于 Spring Boot，您可以使用活动配置文件或配置名称运行测试用例，使用 -Dspring.config.name=test 传递运行时 VM 参数以运行测试用例等。

希望这个帮助，其余的都是不言自明的。

将 JerseyTest 与 Spring 集成的更好方法
  • junit 测试类中没有从 JerseyTest 继承
  • junit 测试类中没有对 Jersey 的依赖，只是纯粹的 jax-rs 依赖
  • 完美集成 SpringJUnit4ClassRunner 和 @ContextConfiguration

我的解决方案托管在 github 上。希望这对您有所帮助。
