我正在尝试将服务注入使用Jersey的Rest类.

无论我尝试注入此类的内容是什么或如何在运行时都显示为null.查看日志文件显示在初始化Web应用程序时调用setJsonTestService,此时它不为null.但是,当稍后通过对此类的PUT请求访问它时,它为空.

我完全不知所措.

这个类看起来像这样:

@Named
@Path("JsonTest")
public class JsonTest {
    @Context
    Request request;
    @Context
    UriInfo uriInfo;

    protected final Logger log = Logger.getLogger(getClass());

    private JsonTestService jsonTestService;

    @Autowired
    public void setJsonTestSerivce(JsonTestService jsonTestService) {
        log.info("Setting JsonTestService.");
        if (jsonTestService == null) {
            log.info("JsonTestService is null at injection");
        }
        this.jsonTestService = jsonTestService;
    }

    @Inject
    public ScrapIntermediate scrapIntermediate; // just a plain empty class with an is true method

    @PUT
    @Path("{id}")
    @Produces(MediaType.APPLICATION_JSON)
    public void putJson(@PathParam("id") String id) {
        log.info("Putting some json at " + id);
        if …

我一直在尝试为我的DAO创建一个使用Hibernate的JUnit测试,并通过我的applicationContext.xml文件中的Spring链接到数据库.

添加时仅发生错误:

@RunWith(SpringJUnit4ClassRunner.class)

否则我得到partDao的空指针异常,这是预期的,因为它没有链接.

通常情况下,我只是说废弃它并继续开发没有JUnit测试,但我更愿意在我的项目中开始使用它.

这是错误:

这是我的测试类:

    @Autowired

    public PartDaoTest() {}
