Question

我有一个spring boot应用程序，当我从我的Intellij本地运行runnable Application类的Spring启动时，它运行得很好。

我的模块PRESENT依赖于另一个模块OLDER。所以我在PRESENT的pom.xml中添加了B作为依赖项。

我的pom.xml的主要部分是：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.4.RELEASE</version>
</parent>

<dependency for Module OLDER>


<plugin> 
    <groupId>org.springframework.boot</groupId>               
    <artifactId>spring-boot-maven-plugin</artifactId>
</plugin>

我在beans.xml（在模块PRESENT中）中有几个bean，所以我在app-context.xml中导入了beans.xml（其中包含了模块OLDER的所有bean）。

  <beans xmlns="http://www.springframework.org/schema/beans" ...>
      <import resource="classpath:/app-context.xml"/>
      //more beans
  </beans>

我在ThreadService中有一个服务Module OLDER，在MODULE PRESENT中的一个控制器中，我已自动启用此ThreadService。当我在本地运行它工作正常，但是当我创建一个jar时它没有检测到app-context.xml并给出以下异常

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from URL location [classpath:/app-context.xml]

我搜索了一下并改变了

<import resource="classpath:/app-context.xml"/>

到

<import resource="classpath*:**/app-context.xml"/>

现在它检测到app-context.xml但无法自动装配ThreadService。

   org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myHandler': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.x.y.service.ThreadService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

我不确定为什么spring-boot无法检测到bean。

我尝试了以下内容：

尝试在@ImportResource("classpath:/beans.xml")以及my controller课程中添加Application。

我尝试使用repackage

   <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <version>1.2.5.RELEASE</version>
        <executions>
            <execution>
                <goals>
                    <goal>repackage</goal>
                </goals>
            </execution>
        </executions>
    </plugin>

Spring启动jar不会检测依赖模块中定义的bean
