无法实例化[org.springframework.orm.jpa.JpaVendorAdapter]：工厂方法＆＃39; jpaVendorAdapter＆＃39;抛出异常;

Question

我正在创建一个简单的SpringBoot应用程序（版本：1.5.9.RELEASE）并使用普通的JPA。这是 application.properties 文件：

    server.port: 8083
    spring.datasource.url=jdbc:mysql://localhost:3306/restdb
    spring.datasource.username=ricky
    spring.datasource.password=ricky
    spring.datasource.driver-class-name=com.mysql.jdbc.Driver

我的 pom.xml 如下所示

                    </plugins>
        </build>

当我尝试运行此应用程序时; 以Spring Boot App运行，它将重新进入以下异常。
