Spring Jersey应用程序的Jersey测试中资源模型验证失败
我有一个带注释的Spring Jersey应用程序。我正在尝试使用Spring Jersey应用程序的Jersey测试中资源模型验证失败,spring,jersey,jersey-2.0,jersey-test-framework,Spring,Jersey,Jersey 2.0,Jersey Test Framework,我有一个带注释的Spring Jersey应用程序。我正在尝试使用JerseyTest为我的控制器设置单元测试。我在运行测试时遇到了以下错误,我无法找出这些错误。我错过了什么 SEVERE: Following issues have been detected: WARNING: No injection source found for a parameter of type public com.example.services.dto.UnitDto com.example.apis.

为我的控制器设置单元测试。我在运行测试时遇到了以下错误,我无法找出这些错误。我错过了什么
SEVERE: Following issues have been detected:

at org.glassfish.jersey.server.ApplicationHandler.initialize(ApplicationHandler.java:555)
控制器类如下所示:
@Component
@Path("/app/units")
public class UnitResource {
@Context
private UriInfo uriInfo;
@Context
private Request request;
@Inject
private UnitService unitService;
@Inject
public UnitResource(@Named("UnitService") UnitService unitService) {
this.unitService = unitService;
}
@GET
@Produces(MediaType.APPLICATION_JSON)
@Timed(absolute = true, name = "getUnitForPoint")
public UnitDto getUnits(@QueryParam("contains") @NotNull PointDto point) throws PointOutsideBounds {
return unitService.getUnitForPoint(point);
}
}
public class UnitResourceTest extends JerseyTest {
@Mock
private UnitService unitService;
@Override
protected ResourceConfig configure() {
ResourceConfig rc = new ResourceConfig()
// .register(new UnitResource(Mockito.mock(UnitService.class))) -- has the same effect
.register(UnitResource.class)
.property("contextConfig", new AnnotationConfigApplicationContext(ApplicationConfiguration.class));
enable(TestProperties.LOG_TRAFFIC);
enable(TestProperties.DUMP_ENTITY);
forceSet(TestProperties.CONTAINER_PORT, "0");
return rc;
}
@Before
public void setUp() throws Exception {
super.setUp();
initMocks(this);
}
@Override
protected TestContainerFactory getTestContainerFactory() {
return new InMemoryTestContainerFactory();
}
@Test
public void testGetUnit() throws PointOutsideBounds {
Response response = target()
.path("/app/units")
.queryParam("contains", new Point(0.0,0.0).toJson())
.request(MediaType.APPLICATION_JSON_TYPE)
.get();
assertThat(response.getStatus(), is(Response.Status.OK));
}
}
测试等级如下:
@Component
@Path("/app/units")
public class UnitResource {
@Context
private UriInfo uriInfo;
@Context
private Request request;
@Inject
private UnitService unitService;
@Inject
public UnitResource(@Named("UnitService") UnitService unitService) {
this.unitService = unitService;
}
@GET
@Produces(MediaType.APPLICATION_JSON)
@Timed(absolute = true, name = "getUnitForPoint")
public UnitDto getUnits(@QueryParam("contains") @NotNull PointDto point) throws PointOutsideBounds {
return unitService.getUnitForPoint(point);
}
}
public class UnitResourceTest extends JerseyTest {
@Mock
private UnitService unitService;
@Override
protected ResourceConfig configure() {
ResourceConfig rc = new ResourceConfig()
// .register(new UnitResource(Mockito.mock(UnitService.class))) -- has the same effect
.register(UnitResource.class)
.property("contextConfig", new AnnotationConfigApplicationContext(ApplicationConfiguration.class));
enable(TestProperties.LOG_TRAFFIC);
enable(TestProperties.DUMP_ENTITY);
forceSet(TestProperties.CONTAINER_PORT, "0");
return rc;
}
@Before
public void setUp() throws Exception {
super.setUp();
initMocks(this);
}
@Override
protected TestContainerFactory getTestContainerFactory() {
return new InMemoryTestContainerFactory();
}
@Test
public void testGetUnit() throws PointOutsideBounds {
Response response = target()
.path("/app/units")
.queryParam("contains", new Point(0.0,0.0).toJson())
.request(MediaType.APPLICATION_JSON_TYPE)
.get();
assertThat(response.getStatus(), is(Response.Status.OK));
}
}
应用程序配置类为:
@Configuration
@ComponentScan("com.example")
public class ApplicationConfiguration {
@Bean(name="UnitService")
public UnitService unitService() {
return new UnitService();
}
}
我的测试配置的渐变依赖项是:
dependencies {
// Using junit-dep package to get junit without hamcrest dependency
testCompile("junit:junit-dep:4.8.2")
testCompile("org.hamcrest:hamcrest-all:1.3")
testCompile("org.mockito:mockito-all:1.8.4")
testCompile ('org.glassfish.jersey.test-framework:jersey-test-framework-core:2.22.2')
testCompile('org.glassfish.jersey.test-framework.providers:jersey-test-framework-provider-inmemory:2.22.2')
}
configurations {
testCompile.exclude group: 'org.glassfish.jersey.ext', module: 'jersey-spring3'
}
我找到了,但都没有解决我的问题。注意:在大多数情况下,这个答案适用于所有带注释的参数
指向
参数的点似乎是问题所在
public UnitDto getUnits(@QueryParam("contains") @NotNull PointDto point)
查询参数是字符串。Jersey能够将该字符串转换为一些基本类型,如int
、boolean
、Date
,等等。但它不知道如何从该字符串创建指向的点。这并不意味着我们不能使用自定义类型。我们只需要遵循一些规则:
具有接受字符串的构造函数。然后我们需要自己从这个字符串构造对象。比如说
public PointDto(String param) {
Map<String, Object> map = parseJson(param);
this.field1 = map.get("field1");
this.field2 = map.get("field2");
}
您可以使用参数转换器提供程序
。我不会举一个例子,但您可以阅读更多关于如何实现它的内容。你也可以看到
请注意,此答案中提供的信息位于的javadoc中。谢谢。完全没有注意到这一点。我正在重新考虑将JSON作为查询参数传递。我将发送一个逗号分隔的字符串,如x,y,z
,并在控制器内部初始化PointDto
。我猜这是因为当Jersey试图查找SpringXML上下文文件时,您从Jersey获得了filenotfoundexception。您可以查看中的配置,了解如何使用注释配置。这样,您就可以在测试中使用不同的Spring配置文件,而不必对所有内容都使用mock。我想我会提出来的。谢谢,这很有帮助。我现在正在编写单元测试,所以我确实需要模拟一切。但我会在开发集成测试时使用它。实际上,不用担心。再看看你的代码,你已经这样做了:-)我不是一个Gradle用户,所以我可能误解了testCompile.exclude
的意思
