WELD-001318无法解决模糊的依赖关系

Question

部署我的应用程序时出现错误,如下所示.

Caused by: org.jboss.weld.exceptions.AmbiguousResolutionException: WELD-001318 Cannot resolve an ambiguous dependency between [
Producer Method [String] with qualifiers [@Any @Config] declared as [[method] @Produces @Config public ca.comdev.cdip.mis.enterpriseportal.configuration.ConfigurationProvider.getConfigurationValue(InjectionPoint)], 

Producer Method [String] with qualifiers [@Any @Config] declared as [[method] @Produces @Config public ca.comdev.cdip.mis.enterpriseportal.configuration.ConfigurationProvider.getConfigurationValue(InjectionPoint)]]

我只有这样的方法,其标题看起来像这样

@Produces @Config public String getConfigurationValue(InjectionPoint p) throws ConfigurationException{...}

和班级有这些

@Named
@Singleton
@Startup
public class ConfigurationProvider {...}

请帮忙.这个错误可能比我的代码更模糊.

我因在 2 个不同的模块中意外使用相同的 EJB 名称“ExternalClient”而发生此错误。

 <enterprise-beans>
    <session>
        <ejb-name>ExternalClient</ejb-name> <!-- DUPLICATED -->
        <ejb-class>com.company.ExternalClient</ejb-class>
        <session-type>Stateless</session-type>
        <env-entry>
            <env-entry-name>url</env-entry-name>
            <env-entry-type>java.lang.String</env-entry-type>
            <env-entry-value>http://company.com/API</env-entry-value>
        </env-entry>
    </session>
</enterprise-beans>

使用 JBoss 时可以通过在部署期间检查 JNDI 绑定来检测到这一点。EJB 被多次实例化。
