java.lang.AssertionError : expected:<200> but was:<404> in jersey restful services unit test

Question

我有这个类JerseySpringSuiteTest.java:

@RunWith(Suite.class)
@Suite.SuiteClasses({ ProductTest.class })
public class JerseySpringSuiteTest {
    public static JerseyTest jerseyTest;

    @BeforeClass
    public static void init() {
        jerseyTest = new JerseyTest(new WebAppDescriptor.Builder("com.product.resource")
                .contextParam("contextConfigLocation", "classpath:applicationContext.xml").servletClass(SpringServlet.class)
                .contextListenerClass(ContextLoaderListener.class).requestListenerClass(RequestContextListener.class).build()) {

        };
    }
}

和ProductTest.java:

public class ProductTest{

    @Before
    public void before() throws Exception {
        JerseySpringSuiteTest.jerseyTest.setUp();
        ExecutorService productExecutorService = ContextLoaderListener.getCurrentWebApplicationContext().getBean(
                "productExecutorService", ExecutorService.class);
        Assert.assertNotNull(productExecutorService);
    }

    @Test
    public void testNoAction() {
        WebResource webResource = JerseySpringSuiteTest.jerseyTest.resource();
        String responseMsg = webResource.path("product/").get(String.class);
        Assert.assertEquals("No Action Specified", responseMsg);
    }

    @Test
    public void testGetProducts() throws URISyntaxException {
        WebResource webResource = JerseySpringSuiteTest.jerseyTest.resource().path(
                "Products/rest/product/getProducts/1/productName/01-01-2013/");
        ClientResponse response = webResource.accept(MediaType.APPLICATION_JSON).get(ClientResponse.class);

        Assert.assertEquals(200, response.getStatus());
    }
}

和Product.java:

@Component
@Path("/product")
public class Product{
    @Autowired
    private ProductService productService;

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Object noAction() {
        return "No Action Specified";
    }

    @GET
    @Path("/getProducts/{companyID}/{companyName}/{date}")
    @Produces(MediaType.APPLICATION_JSON)
    public Object getProducts(@PathParam("companyID") final int companyID,
            @PathParam("date") final String date, @PathParam("companyName") final String companyName)
            throws IOException {
        return productService.getProducts(companyID, companyName, date);
    }
}

当我执行它时，我看到:

当我在浏览器中 ping URL 时，我能够获取数据。

有人可以帮我获取 200 和 JSON 对象的响应状态吗？

注意:我使用的是 jersey 1.17.1 版本和 grizzly2 容器。

Answer 1

根据您的 noAction 单元测试，正确的 URL 似乎是:

webResource.path("product/")

这也可以通过您的实际服务等级来确认:

@Path("/product")
public class Product {
   //...
}

这意味着您需要更改其他测试以使用相同的路径。

此外，根据您的服务类别，它是 companyName，而不是 productName。

@Test
public void testGetProducts() throws URISyntaxException {

    WebResource webResource = JerseySpringSuiteTest.jerseyTest.resource();
    ClientResponse response =
        webResource.path("product/getProducts/1/companyName/01-01-2013/")
                   .accept(MediaType.APPLICATION_JSON)
                   .get(ClientResponse.class);

    Assert.assertEquals(200, response.getStatus());
}

它在浏览器中工作的一个可能原因是您的服务器(Tomcat、Jetty 等)配置为将公共(public) URL 前缀 Products/rest 添加到所有路径。当您执行单元测试时，该服务器不在图中。
