使用泽西测试框架在Jerseytest构造器期间产生NullPoInterException

Question

我正在使用泽西测试框架，但是，即使在代码进行测试之前，JerseyTest构造函数都会失败：

Mar 06, 2014 6:40:44 PM org.glassfish.jersey.server.ApplicationHandler initialize
INFO: Initiating Jersey application, version Jersey: 2.6 2014-02-18 21:52:53...
A MultiException has 3 exceptions.  They are:
1. java.lang.NullPointerException
2. java.lang.IllegalStateException: Unable to perform operation: method inject on com.sun.jersey.core.impl.provider.entity.XMLRootElementProvider$App
3. java.lang.IllegalStateException: Unable to perform operation: create on org.glassfish.jersey.message.internal.MessageBodyFactory
MultiException stack 1 of 3

我的测试非常简单：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"/applicationContext-test.xml"})
public class BidAPITest extends JerseyTest {
    @Override
    protected Application configure() {
        return new ResourceConfig(BidAPI.class);
    }
    @Test
    public void testCreate() {
        final BidDocument
            bid =
                target(BidAPI.PATH)
                    .request()
                    .post(
                        Entity.entity("", MediaType.APPLICATION_JSON_TYPE),
                        BidDocument.class
                    );
        System.out.println(bid);
    }
}

在AbstractJaxBprovider中调用SetConfiguration时发生的实际故障发生。在Jettytest构造函数中失败的实际线路是：

public ComponentModelValidator(ServiceLocator locator) {
    validators = Lists.newArrayList();
    validators.add(new ResourceValidator());
    /* -FAILS-> */ validators.add(new RuntimeResourceModelValidator(locator.getService(MessageBodyWorkers.class)));
    validators.add(new ResourceMethodValidator(locator));
    validators.add(new InvocableValidator());
}

在我开始拆除我的申请之前，有什么想法吗？

谢谢。-ap _

我使用Spring 3.2.6＆amp;泽西2.6。我通过将球衣升级到2.9.1。

来解决它。

还确保您使用此依赖项使Spring 3＆amp;泽西岛共处：

<dependency>
    <groupId>org.glassfish.jersey.ext</groupId>
    <artifactId>jersey-spring3</artifactId>
    <version>2.9.1</version>
    <exclusions>
    <exclusion>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
    </exclusion>
     </exclusions>
</dependency>
