这是尝试运行我的Web应用程序时引发的错误:

[INFO] WARNING: Nested in org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private javax.sql.DataSource org.springframework.boot.autoconfigure.orm.jpa.JpaBaseConfiguration.dataSource; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceAutoConfiguration$NonEmbeddedConfiguration.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public javax.sql.DataSource org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration$NonEmbeddedConfiguration.dataSource()] threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Cannot determine embedded database driver class for database type NONE.

spring-boot:run当项目的父POM由于其子项而使用打包模式POM时,是否可以使用Spring Boots Maven插件命令？

我有一个带有"主"POM的多模块maven项目,它是Spring Boot Parent模块的子项.看起来像这样:

    <modelVersion>4.0.0</modelVersion>

    <groupId>com.example</groupId>
    <artifactId>project</artifactId>
    <packaging>pom</packaging>
    <version>0.1.0</version>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.2.0.BUILD-SNAPSHOT</version>
        <relativePath/>
    </parent>

    <modules>
        <module>module1</module>
        <module>module2</module>
        <module>module3</module>
    </modules>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <start-class>com.example.module1.Application</start-class>
        <java.version>1.8</java.version>
    </properties>

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

这基本上是我们的"主人"POM,每个孩子都使用它作为它的父母.现在我们spring-boot:run要从这个"主"POM所在的工作目录中执行命令.问题是,这会生成一个ClassNotFoundException奇数,因为module1(此类Application所在的位置)包含在POM中并作为模块提及.

使用单个模块maven项目,<packaging>jar</packaging>这将编译并运行Application类,因此Spring-Boot不是在这里工作.

spring-boot-maven-plugin在处理多模块Maven项目时,我需要更改什么才能使其工作或者根本无法使用插件？

旁注:我的应用程序类/模块1将其他模块作为依赖项,因此在回答问题时请记住这一点.任何关于如何改进这一点的建议都非常感谢.
