在gradle子项目中找不到Spring资源库组件（Springboot） [英] Spring repository components not found in gradle subproject (Springboot)

问题描述

我有一个多项目gradle项目：

ht-java

• ht-domain


• ht-scraper

ht-scraper使用域模型和daos它们位于ht域。
当我启动springboot应用程序时，出现以下错误：

  org.springframework.beans.factory.NoSuchBeanDefinitionException：找不到符合条件的[com.hypetube.domain.dao.ChannelRepository]类型的符合条件的Bean：期望至少1个符合此依赖关系自动装配候选资格的bean。依赖注释：{@ org.springframework.beans.factory.annotation.Autowired（required = true）} 
  

当我有ht-scraper中的存储库类时，一切正常。

我的spring应用程序如下所示：

  @Configuration 
 @EnableAutoConfiguration 
 @ComponentScan（{com.hypetube，com.hypetube.domain}）
 @EnableConfigurationProperties //使用它来注册其他属性来源，例如属性文件
 public class Application {
 
 private static final Logger log = LoggerFactory.getLogger（Application.class）; 
 
 public static void main（String [] args）{
 SpringApplication.run（Application.class）; 
 
 
 @Bean 
 public RestTemplate restTemplate（）{
 return new RestTemplate（）; 
} 
 
 @Autowired 
 private环境env; 
 
 @PostConstruct $ b $ public void printActiveSpringProfiles（）{
 log.info（以下春季配置文件处于活动状态：{}，new ArrayList<>（Arrays.asList（env .getActiveProfiles（））））; 
 
 
  

settings.gradle：

 包括'ht-domain'，'ht-scraper'
  

build.gradle（ht.scraper）：

  compile project（：ht-domain ）
  

一切正常，该项目编译没有错误即将发生。
只是当我启动应用程序时出现错误。

解决方案

很奇怪为什么 spring -boot 插件不包含 ht-domain 子项目。要解决方法测试，请将以下代码添加到 ht-scraper / build.gradle

  test {
 classpath = project（：ht-domain）。sourceSets.main.runtimeClasspath 
} 
  

但运行打包应用程序仍然存在问题。我从 PlaylistRepository 类中删除了所有注释，并将以下注释添加到 Application ：

  @EnableMongoRepositories（{com.hypetube.domain}）
  

不，它开始顺利 - 至少没有类路径问题。希望这有助于某种方式，正如我所说的很奇怪的行为：/ $ /

I have a multi project gradle project:

ht-java

• ht-domain
• ht-scraper

ht-scraper uses the domain model and daos which are located in ht-domain. when i start the springboot app i get the following error:

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.hypetube.domain.dao.ChannelRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

when i have the repository classes within ht-scraper everything works fine.

my spring app looks like this:

@Configuration
@EnableAutoConfiguration
@ComponentScan({"com.hypetube", "com.hypetube.domain"})
@EnableConfigurationProperties //use this to register other properties sources e.g. property files
public class Application {

    private static final Logger log = LoggerFactory.getLogger(Application.class);

    public static void main(String[] args) {
        SpringApplication.run(Application.class);
    }

    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }

    @Autowired
    private Environment env;

    @PostConstruct
    public void printActiveSpringProfiles() {
        log.info("Following spring profiles are active: {}", new ArrayList<>(Arrays.asList(env.getActiveProfiles())));
    }
}

settings.gradle:

include 'ht-domain', 'ht-scraper'

build.gradle (ht.scraper):

compile project(":ht-domain")

Everything works as it should; The project compiles no errors are imminent. Just when i start the app the error occurs.

解决方案

It's very strange why spring-boot plugin doesn't include the ht-domain subproject. To workaround tests add the following piece of code to ht-scraper/build.gradle

test {
    classpath = project(":ht-domain").sourceSets.main.runtimeClasspath
}

But there's still problem with running packaged application. I've removed all the annotations from PlaylistRepository class and added the following annotation to Application:

@EnableMongoRepositories({"com.hypetube.domain"})

No it starts well - at least there're no classpath issues. Hope that helps somehow and as I said quite weird behavior :/
