我有一个Sping Boot 应用程序，我们为我们的产品安装在一些小服务器上。它一直有效。今天晚上，我们已经安装在我们的服务器之一，它没有启动。
每个服务器都是来自公共映像的映像，因此操作系统是相同的。
当我们启动.jar时，我们得到：

Oct 05, 2016 11:16:45 AM org.apache.catalina.core.StandardService startInternal
INFO: Starting service Tomcat
Oct 05, 2016 11:16:45 AM org.apache.catalina.core.StandardEngine startInternal
INFO: Starting Servlet Engine: Apache Tomcat/8.5.5
Oct 05, 2016 11:16:46 AM org.apache.catalina.core.ApplicationContext log
INFO: Initializing Spring embedded WebApplicationContext
Oct 05, 2016 11:17:03 AM org.apache.catalina.core.StandardService stopInternal
INFO: Stopping service Tomcat

这是我们application.properties关于hibernate的www.example.com

# Username and password
spring.datasource.username = parkuser
spring.datasource.password = xxxxxxxxxxxxxxxxxxxxxx
spring.datasource.url= jdbc:mysql://xxxxxxxxxxxxxxxxxxxxxxxxx:3306/SMARTPARK?useSSL=false

# Keep the connection alive if idle for a long time (needed in production)
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1
spring.jpa.show-sql = false

# Hibernate ddl auto (create, create-drop, update): with "update" the database
# schema will be automatically updated accordingly to java entities found in
# the project
spring.jpa.hibernate.ddl-auto = update

# Naming strategy
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy

# Allows Hibernate to generate SQL optimized for a particular DBMS
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQLDialect
spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

在我们的pom.xml中，我们有

        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.4.1.RELEASE</version>

            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>

        </dependency>

这是我们的StartServer.class

@SpringBootApplication
@EnableScheduling
public class StartServer extends SpringBootServletInitializer{
    public static void main(String[] args){

        SpringApplication.run(StartServer.class, args);

    }

    @Bean
    public HibernateJpaSessionFactoryBean sessionFactory() {
        return new HibernateJpaSessionFactoryBean();
    }
}

我不能理解为什么同一个jar在一个设备中工作，而在另一个设备中给出了这个错误，我不能理解哪个是错误...
