Spring引导应用程序无法启动

Question

我有一个Spring Boot应用程序，我们在我们的产品的一些小型服务器上安装该应用程序。它一直工作。今天晚上，我们已经将它安装在我们的一台服务器上，并没有启动。

每台服务器都是来自一个共同映像的映像，所以操作系统是相同的。

当我们推出我们正在将.jar：

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这对于休眠

# 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

<parent> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-parent</artifactId> 
     <version>1.4.1.RELEASE</version> 
    </parent> 
    <dependencies> 
     <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter</artifactId> 
      <exclusions> 
       <exclusion> 
        <groupId>org.springframework.boot</groupId> 
        <artifactId>spring-boot-starter-logging</artifactId> 
       </exclusion> 
      </exclusions> 
     </dependency> 
     <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter-log4j</artifactId> 
      <version>1.3.8.RELEASE</version> 
     </dependency> 
     <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter-data-jpa</artifactId> 
     </dependency> 
     <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter-jdbc</artifactId> 
     </dependency> 
     <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter-data-rest</artifactId> 
     </dependency> 
     <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter-web</artifactId> 
     </dependency> 
     <dependency> 
      <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(); 
    } 
} 

我无法理解为什么在一个设备中的同一个jar的作品，而在另一个人给这个错误，我不明白这是错误...

我不是100％肯定，但我将不得不更换此：

<dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter</artifactId> 
    .... 
</dependency> 

利用该：

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

    <properties> 
     <java.version>1.8</java.version> 
    </properties> 

    <dependencies> 
... 
</dependencies> 

参见例如因此下面：

<groupId>org.springframework</groupId> 
    <artifactId>gs-relational-data-access</artifactId> 
    <version>0.1.0</version> 

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

    <properties> 
     .... 
    </properties> 

    <dependencies> 

     <dependency> 
      .... 
     </dependency> 

     <dependency> 
      <groupId>mysql</groupId> 
      <artifactId>mysql-connector-java</artifactId> 
      <version>[5,]</version> 
     </dependency> 
    </dependencies> 

否则，只是这样做：

<dependency> 
       <groupId>mysql</groupId> 
       <artifactId>mysql-connector-java</artifactId> 
       <version>your version</version> 
      </dependency>

我遇到了同样的问题。然后清理我的本地Maven仓库后，应用程序启动并运行。清理你的本地maven回购（由于依赖损坏）并重试！
