Question

我有两个弹簧启动应用程序，一个作为依赖项添加到另一个。依赖子项目能够自行运行。创建了能够访问的分类器。

@SpringBootApplication(scanBasePackages = "com.project.subproject")
public class Application {
    public static void main(String args[]) {
        new SpringApplicationBuilder(Application.class)
                .properties("spring.config.name=application-subproject-default").run(args);
    }
}

此应用程序与其自己的数据源，控制器和放大器完美配合。建议

添加了子项目：

<dependency>
   <groupId>com.project.subproject</groupId>
   <artifactId>subproject</artifactId>
   <version>0.0.1-SNAPSHOT</version>
   <exclusions>
      <exclusion>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-undertow</artifactId>
      </exclusion>
    </exclusions>

父项目Spring启动应用程序：

@SpringBootApplication(scanBasePackages = "com.project")
public class MainApplication {
    public static void main(String args[]) {
        new SpringApplicationBuilder(MainApplication.class).properties("spring.config.name=application-parent-default").run(args);
    }
}

application-parent-default.yml
spring:
  application:
    name: parent

从父项扫描子项目，但数据源初始化失败。

    Unsatisfied dependency expressed through field 'jdbcTemplate'; 
    nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.jdbc.JdbcTemplateAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0; 
    nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Bean instantiation via factory method failed; 
nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception; 
nested exception is org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: 
Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. 
If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active)

看起来没有调用子项目中的@SpringBootApplication来初始化yml文件。

任何见解都会有所帮助
