我在其余应用程序上使用spring boot 1.3.0.我正在尝试使用RestAssured创建集成测试.@Context出现问题.对于我来说,它不会注入到控制器中以获取URI.

这是测试类：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
@WebIntegrationTest("server.port=8080")
@ActiveProfiles(value = {"testing"})
public class InvoiceRestServiceIT {

    private static String INVOICE_DATA = "<invoice data>";
    private static String INVOICE_URL = "/customers/1q2w3e4r/invoices";

    @Test
    public void testPostInvoice() {
        given()
           .contentType(ContentType.JSON)
           .accept(ContentType.JSON)
           .body(INVOICE_DATA)
         .expect()
            .statusCode(200)
            .body(containsString("entity"), containsString("id"))
         .when()
            .post(INVOICE_URL);;
    }
}

这是服务类(InvoiceRestService.java)：

@Autowired
private InvoiceController invoiceController;

@POST
public EntityResponse add(InvoiceResource invoiceResource) {
    return new EntityResponse(invoiceController.createInvoice(invoiceResource));
}

这是控制器(InvoiceController扩展了RestController)：

protected Customer getCustomer() {
    Customer customer = customerRepository.findOne(getCustomerId());
...
}

这是发生错误的地方(RestController.java)：

@Context
private HttpServletRequest request;

protected String getCustomerStringId() {
    Matcher matcher = pattern.matcher(request.getRequestURI()); //<---- Here, request object is null
    if (!matcher.find()) {
        throw new IllegalStateException("Cannot find customer id in request URL");
    }

    return matcher.group(1);
}

这是错误日志：

有人遇到过吗？如何解决这个问题？

解决方法:

看来您的控制器更像是实用程序类,并且您的服务实际上是一个控制器.因此,就此而言,您的InvoiceController可能不是JAX RS根资源.

我认为最简单的解决方案(如果要继续执行此方法)是删除@Context私有HttpServletRequest请求；在RestController中声明,然后将其移动到InvoiceRestService,如下所示：

@POST
public EntityResponse add(InvoiceResource invoiceResource, @Context HttpServletRequest request) {
    return new EntityResponse(invoiceController.createInvoice(invoiceResource, request));
}

然后,您需要将请求传递到InvoiceController实用程序.

但是…最优雅的解决方案是让JAX RS从传入路径解析ID.使用@Path可以为路径的命名段定义占位符,并将这些段注入到JAX RS端点方法中,如下所示：

@Path("/customers/{customerId}/invoices")
public class InvoiceRestService {

  @POST
  public EntityResponse add(@PathParam("customerId") String customerId, InvoiceResource invoiceResource) {
    return new EntityResponse(invoiceController.createInvoice(invoiceResource, customerId));
  }
}
