    public class ApplicationBinder extends AbstractBinder {

        @Override
        protected void configure() {
              @Override
              protected void configure() {

          bind(AuthenticationTokenService.class).to(AuthenticationTokenService.class);
             }
        }
    }

这是泽西岛的注册资源。

@ApplicationPath("api")
public class JerseyConfig  extends ResourceConfig {

    public JerseyConfig() {

        packages("com.skillsimprover.restexamples.rest");
        register(JacksonJsonProvider.class);
        register(new ApplicationBinder());

    }
}

这是托管bean

 @ApplicationScoped
public class AuthenticationTokenService {

       @Inject
      private SysLang locale;

    @Inject
    @Configurable( "authentication.jwt.validFor" )
    private Long validFor;

    @Inject
    @Configurable( "authentication.jwt.refreshLimit" )
    private Integer refreshLimit;

    @Inject
    private AuthenticationTokenIssuer tokenIssuer;

    @Inject
    private AuthenticationTokenParser tokenParser;

    public String issueToken(String username, Set<Authority> authorities) {
        String id = generateTokenIdentifier();

          ZonedDateTime issuedDate = ZonedDateTime.now();

        ZonedDateTime expirationDate = calculateExpirationDate(issuedDate);

        AuthenticationTokenDetails tokenDetails = new AuthenticationTokenDetails();

        tokenDetails.setId(id);
        tokenDetails.setUsername(username);
        tokenDetails.setAuthorities(authorities);
        tokenDetails.setIssuedDate(issuedDate);
        tokenDetails.setExpirationDate(expirationDate);
        tokenDetails.setRefreshCount(0); 
        tokenDetails.setRefreshLimit(refreshLimit);

        return tokenIssuer.issueToken(tokenDetails);
    }
    public AuthenticationTokenDetails parseToken(String token) {
        return tokenParser.parseToken(token);
    }


    public String refreshToken(AuthenticationTokenDetails currentTokenDetails) {

        if (!currentTokenDetails.isEligibleForRefreshment()) {

            MessageException tokenCannotRefreshed = MessageException.TOKEN_CANNOT_REFRESHED;
            final String messageException = getMessageExceptionSys(tokenCannotRefreshed, locale.getLang());

            throw new AuthenticationTokenRefreshmentException(messageException);
        }

        ZonedDateTime issuedDate = ZonedDateTime.now();

        ZonedDateTime expirationDate = calculateExpirationDate(issuedDate);

        AuthenticationTokenDetails newTokenDetails = new AuthenticationTokenDetails();

        newTokenDetails.setId(currentTokenDetails.getId());
        newTokenDetails.setUsername(currentTokenDetails.getUsername());
        newTokenDetails.setAuthorities(currentTokenDetails.getAuthorities());
        newTokenDetails.setIssuedDate(issuedDate);

        newTokenDetails.setExpirationDate(expirationDate);
         newTokenDetails.setRefreshCount(currentTokenDetails.getRefreshCount() + 1);
        newTokenDetails.setRefreshLimit(refreshLimit);



        return tokenIssuer.issueToken(newTokenDetails);
    }

    private Long validFor2 = this.validFor;

    private ZonedDateTime calculateExpirationDate(ZonedDateTime issuedDate) {

        System.out.println(validFor2);
        return issuedDate.plusSeconds(validFor);
    }

    private String generateTokenIdentifier() {
        return UUID.randomUUID().toString();
    }
}

这是EndPoint

@Provider
@Produces( MediaType.APPLICATION_JSON )
@Consumes( MediaType.APPLICATION_JSON )
@Path("auth")
public class AuthenticationResource {

    @Resource
    private WebServiceContext context;

    @Inject
    private AuthenticationTokenService authenticationTokenService;


    private static final String VIEW_URL = "/WEB-INF/pages/home.html";

    @POST
    @PermitAll
    @Path("username")
    public Response authenticateUserName(UserCredentials credentials,     
    @Context HttpServletRequest request)  {

        UsernamePasswordValidator usernamePasswordValidator = new  
       UsernamePasswordValidator();
        usernamePasswordValidator.validateUsername(credentials, request);

     ....

这是SysLang类

    static {

        lang = localeDefault.getLanguage();
    }

    public SysLang() {
    }

    public String getLang() {
        return lang;
    }

}

这是使用CDI容器进行管理的类。

库“ Weld”实现规范CDI。我使用特定批注(来自Scope类型)安装的所有Java bean必须使用CDI容器“ Weld”库进行管理。  但是,一旦我从客户端开始将ajax查询发送给其他服务(即,给班级),注入点和生产方法就无法工作 AuthenticationResource

所需组分未在此处注入。我收到错误消息...

  

org.glassfish.jersey.internal.Errors.logErrors以下警告   已检测到:警告:检测到未知的HK2故障:   MultiException堆栈1 of 7   org.glassfish.hk2.api.UnsatisfiedDependencyException:没有   可在以下位置注入的对象   SystemInjecteeImpl(requiredType = SysLang,parent = AuthenticationTokenService,qualifiers = {},position = -1,optional = false,self = false,unqualified = null,1585822177)   org.jvnet.hk2.internal.ThreeThirtyResolver.resolve(ThreeThirtyResolver.java:75)

为什么? 请向我解释这个错误的正确性以及为什么会出现此错误

我执行了这个

public class ApplicationBinder extends AbstractBinder {

    @Override
    protected void configure() {
      bind(SysLang.class).to(SysLang.class);
      bind(AuthenticationTokenService.class).to(AuthenticationTokenService.class);
    }
}

结果我得到

  

Servlet的Servlet.service()   [com.skillsimprover.restexamples.rest.jersey.common.registrationconfig.JerseyConfig]   在与path []的上下文中抛出异常   [java.lang.NullPointerException]根本原因   java.lang.NullPointerException at

     

com.skillsimprover.restexamples.rest.jersey.security.service.token。   AuthenticationTokenService。   computeExpirationDate(AuthenticationTokenService.java:194)

那不能提供数据的生产方法。

@ApplicationScoped
public class ConfigurationProducer {

    private Properties properties;

    @PostConstruct
    public void init() {

        properties = new Properties();
        String path = "/application.properties";

        try(InputStream stream = ConfigurationProducer.class.getResourceAsStream(path)) {

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

        } catch (final IOException e) {
            throw new RuntimeException("Configuration file cannot be loaded.");
        }
    }

    @Produces
    @Configurable
    public String produceString(InjectionPoint ip) {

        return getStrProperty(ip);
    }

    @Produces
    @Configurable
    public Integer produceInteger(InjectionPoint ip) {

        return Integer.valueOf(getStrProperty(ip));
    }

    @Produces
    @Configurable
    public Long produceLong(InjectionPoint ip) {

        return Long.valueOf(getStrProperty(ip));
    }

    @Produces
    @Configurable
    public Boolean produceBoolean(InjectionPoint ip) {

        return Boolean.valueOf(getStrProperty(ip));
    }



    private String getStrProperty(InjectionPoint ip){

        String key = getKey(ip);

        return properties.getProperty(key);
    }


    private String getKey(InjectionPoint ip) {

        Annotated annotated = ip.getAnnotated();
        Configurable annotation = annotated.getAnnotation(Configurable.class);

        return annotation.value();
    }
}

Authenticationresource类使用批注@Produces和@ Inject,HK2不了解如何继续?

Weld也使用相同的注释。怎么做?
