Mobilefirst 8.0.0 Spring bean 配置失败

Question

这可能有点远……

我正在尝试注册 bean 和 jax-rs 资源，但没有任何运气。

java.lang.RuntimeException: User code thrown exception: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.github.mfpdev.adapters.spring.integration.JAXRSResourcesRegistryImpl#0' defined in class path resource [applicationContext.xml]: Cannot create inner bean 'com.example.FeatureToggleAdapterResource#311640f7' of type [com.example.FeatureToggleAdapterResource] while setting bean property 'resources' with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.example.FeatureToggleAdapterResource#311640f7' defined in class path resource [applicationContext.xml]: Cannot resolve reference to bean 'featureToggleService' while setting constructor argument; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'featureToggleService' available

我有一个配置类，它应该连接 bean。

@Configuration

@ComponentScan

public class BeanConfig {

    @Bean(name = "configurationService")

    public ConfigurationService configurationService() {

        return new ConfigurationServiceImpl();

    }

    @Bean(name = "featureToggleService")

    public FeatureToggleService featureToggleService() {

        return new FeatureToggleServiceImpl(jdbcTemplate());

    }

}

我applicationContext.xml的很空白

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xsi:schemaLocation="http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/beans/spring-beans.xsd">

我正在使用https://github.com/mfpdev/mfp-advanced-adapters-samples

通过 XML 连接 bean 是我唯一的选择吗？

好吧，我最终到达了那里......需要专门扫描我在调用 bean 的服务上的配置包（据我所知）。@ComponentScan(basePackages = {"com.example.adapter.configuration"})public class FeatureToggleServiceImpl implements FeatureToggleService {}如果有人知道一个更好的地方放@ComponentScan我很想知道。
