java - 无法加载 Jersey 测试中的注入(inject)值

Question

我正在 tomee 中运行我的应用程序，并尝试通过 jersey 测试框架测试我的 jax-rs Web 服务。

我添加了 Maven 依赖项，如下所示:

<dependency>
<groupId>org.glassfish.jersey.test-framework</groupId>
    <artifactId>jersey-test-framework-core</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.glassfish.jersey.test-framework.providers</groupId>
    <artifactId>jersey-test-framework-provider-grizzly2</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.glassfish.jersey.inject</groupId>
    <artifactId>jersey-hk2</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-common</artifactId>
    <version>${jersey.version}</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-json-jackson</artifactId>
    <scope>test</scope>
</dependency>

在我的资源类中，我有

@Inject
private AuthenticationTokenService authenticationTokenService;

在我的服务类别中，我有:

@Inject
private AuthenticationTokenIssuer tokenIssuer;

@Inject
private AuthenticationTokenParser tokenParser;

在这两个类中我有

@Inject
private AuthenticationTokenSettings settings;

我想我的问题是由于 AuthenticationTokenSettings 中的成员引起的

@Inject
@Config("token")
private String token;

这些是通过 Properties 对象从文件中注入(inject)限定符 @Config 的。

我编写了一个 InjectionResolver 类来解析

@Singleton
public static class ConfigInjectionResolver implements InjectionResolver<Configurable>
{
    private static Properties properties;

    public ConfigurableInjectionResolver()
    {
        properties = new Properties();
        InputStream stream = ConfigurationProducer.class.getResourceAsStream("/application.properties");

        if (stream == null)
        {
            throw new RuntimeException("Cannot find application.properties configuration file.");
        }

        try
        {
            this.properties.load(stream);
        }
        catch (final IOException e)
        {
            throw new RuntimeException("Configuration file cannot be loaded.");
        }
    }

    @Override
    public Object resolve(Injectee injectee, ServiceHandle<?> handle)
    {
        if (String.class == injectee.getRequiredType())
        {
            AnnotatedElement elem = injectee.getParent();
            if (elem instanceof Constructor)
            {
                Constructor ctor = (Constructor) elem;
                Configurable config = (Configurable) ctor.getParameterAnnotations()[injectee.getPosition()][0];
                return properties.get(config.value());
            }
            else
            {
                Configurable configurable = elem.getAnnotation(Configurable.class);
                return properties.get(configurable.value());
            }
        }
        return null;
    }

    @Override
    public boolean isConstructorParameterIndicator()
    {
        return true;
    }

    @Override
    public boolean isMethodParameterIndicator()
    {
        return false;
    }
}

在我重写的配置方法中，我创建了这样的抽象绑定(bind)器。

ResourceConfig resourceConfig = new ResourceConfig(
            AuthenticationResource.class);

    resourceConfig.register(new AbstractBinder()
    {
        @Override
        protected void configure()
        {
            bind(AuthenticationTokenService.class).
                    to(AuthenticationResource.class);
            bind(AuthenticationTokenIssuer.class).
                    to(AuthenticationTokenService.class);
            bind(AuthenticationTokenParser.class).
                    to(AuthenticationTokenService.class);
            bind(AuthenticationTokenSettings.class).
                    to(AuthenticationTokenIssuer.class);
            bind(AuthenticationTokenSettings.class).
                    to(AuthenticationTokenParser.class);

            bind(ConfigurableInjectionResolver.class)
                    .to(new TypeLiteral<InjectionResolver<Configurable>>()
                    {
                    })
                    .in(Singleton.class);

.

我有以下异常(exception):

除此之外，我还必须添加以下 Maven 依赖项，因为在我添加用于 Jersey 测试的 Maven 依赖项后，我现有的肥皂类放弃了编译，我无法理解为什么。 我不知道问题是否与此有关。

<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.1</version>
</dependency>
<dependency>
    <groupId>javax.xml.ws</groupId>
    <artifactId>jaxws-api</artifactId>
    <version>2.3.1</version>
</dependency>
<dependency>
    <groupId>javax.jws</groupId>
    <artifactId>javax.jws-api</artifactId>
    <version>1.1</version>
</dependency>

Answer 1

我创建了一个扩展 AnnotationLiteral 的类，如下所示:

public static class ConfigurableQualifierLiteral extends AnnotationLiteral<Configurable> implements Configurable
{
    String value;

    ConfigurableQualifierLiteral(String value)
    {
        this.value = value;
    }

    @Override
    public String value()
    {
        return value;
    }
}

然后在我的 AbstractBinder 中，我绑定(bind)了带注释的成员，如下所示:

bind(Long.valueOf(36000)).to(new TypeLiteral<Long>()
            {
            }).qualifiedBy(new TestAuthenticationResource.ConfigurableQualifierLiteral("authentication.jwt.validFor"));
