ConsumeBeanSpec.groovy

Question

我们如何将Spring应用程序增量迁移到Micronaut？我正在寻找将Spring Beans迁移到Micronaut。我尝试在文档之后使用Spring应用程序中的Micronaut bean，但它并没有消耗

我的示例测试： https://github.com/luistrigueiros/micronaut-expose-spring-beans/blob/master/src/test/groovy/example/ConsumeBeanSpec.groovy

ConsumeBeanSpec.groovy

import groovy.util.logging.Slf4j
import org.springframework.test.context.ContextConfiguration
import spock.lang.Specification

import javax.inject.Inject

@Slf4j
@ContextConfiguration(classes = [Config])
class ConsumeBeanSpec extends Specification {
    @Inject
    ConsumerBean consumerBean

    def "should be able to do something"(){
        expect:
            consumerBean.doSomething()
    }

}

引起：org.springframework.beans.factory.UnsatisfiedDependencyException：在文件[C：\ tools \ micronaut.io \ study \ _meumaut-expose-springs-beans \ out \ production>中定义名称为'consumerBean'的bean创建时出错\ classes \ example \ ConsumerBean.class]：通过构造函数参数0表示的不满意的依赖项;嵌套异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：没有类型'example.ExposedBean'的限定bean可用：预期至少有1个bean可以作为autowire候选者。依赖注释：{} 在org.springframework.beans.factory.support.ConstructorResolver.createArgumentArray（ConstructorResolver.java:729）在org.springframework.beans.factory.support.ConstructorResolver.autowireConstructor（ConstructorResolver.java:192）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.autowireConstructor（AbstractAutowireCapableBeanFactory.java:1274）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBeanInstance（AbstractAutowireCapableBeanFactory.java:1131）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean（AbstractAutowireCapableBeanFactory.java:541）

我已向https://github.com/luistrigueiros/micronaut-expose-spring-beans/pull/1发送了PR，以便您的测试通过。

正如https://docs.micronaut.io/1.0.0.M1/api/io/micronaut/spring/beans/MicronautBeanProcessor.html的javadocs一样，MicronautBeanProcessor仅处理单例bean。

这是在https://github.com/micronaut-projects/micronaut-core/blob/0108642b11d0c6d7f11bcffc85b357e823c98d42/spring/src/main/java/io/micronaut/spring/beans/MicronautBeanProcessor.java#L109实施的。

javadoc对此很清楚。我们将在用户指南中对此进行一些补充。
