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，但没有成功。

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 class，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());
    }
}

我的 applicationContext.xml 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">

    <!-- Define the list of JAX-RS resources to use: -->
    <bean class="com.github.mfpdev.adapters.spring.integration.JAXRSResourcesRegistryImpl">
        <property name="resources">
            <list>
                <bean class="com.example.FeatureToggleAdapterResource">
                    <constructor-arg ref="featureToggleService"/>
                </bean>
            </list>
        </property>
    </bean>

</beans>

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

我唯一的选择是通过 XML 连接 bean 吗？

Answer 1

好吧，我终于做到了...需要在调用 bean 的服务上专门扫描我的配置包（据我所知）。

@ComponentScan(basePackages = {"com.example.adapter.configuration"})
public class FeatureToggleServiceImpl implements FeatureToggleService {}

如果有人知道放置 @ComponentScan 的更好位置，我很想知道。
