SpringBoot - 無法啓動嵌入式Tomcat的

我有一個春天啓動應用程序。它運行在2臺服務器上。這些服務器具有相同的配置。的這種工作原理一一...另一方面開始時SpringBoot - 無法啓動嵌入式Tomcat的

堆棧跟蹤持續了很多行我得到這個例外，主要是我得到的自動佈線和注射活動的問題，與根源

Invocation of init method failed; nested exception is org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set

但我的db.properties文件是：

jdbc.driverClassName = com.mysql.jdbc.Driver 
jdbc.url = jdbc:mysql://192.168.3.240:3306/SMARTPARK?useSSL=false 
jdbc.username = parkuser 
jdbc.password = xxxxxxxxxxxxxxxx 
hibernate.dialect = org.hibernate.dialect.MySQLDialect 
hibernate.show_sql = false 
hibernate.format_sql = false

的DB運行（第二服務器定期連接到它..）和所有特權對用戶和主機是正確的

這是我的pom.xml

我所有的休眠設置在HibernateConfiguration.class（我從遷移Spring MVC的這個程序，春季啓動）

@Configuration 
@EnableTransactionManagement 
@ComponentScan({ "it.besmart" }) 
@PropertySource(value = { "classpath:db.properties" }) 
public class HibernateConfiguration { 

@Autowired 
private Environment environment; 

@Bean 
public LocalSessionFactoryBean sessionfactory(){ 
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean(); 
    sessionFactory.setDataSource(dataSource()); 
    sessionFactory.setPackagesToScan(new String[] {"it.besmart.models"}); 
    sessionFactory.setHibernateProperties(hibernateProperties()); 
    return sessionFactory; 
} 

@Bean 
public DataSource dataSource() { 
    DriverManagerDataSource dataSource = new DriverManagerDataSource(); 
    dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName")); 
    dataSource.setUrl(environment.getRequiredProperty("jdbc.url")); 
    dataSource.setUsername(environment.getRequiredProperty("jdbc.username")); 
    dataSource.setPassword(environment.getRequiredProperty("jdbc.password")); 
    return dataSource; 
} 

private Properties hibernateProperties() { 
    Properties properties = new Properties(); 
    properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect")); 
    properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql")); 
    properties.put("hibernate.format_sql", environment.getRequiredProperty("hibernate.format_sql")); 
    return properties;   
} 

@Bean 
@Autowired 
public HibernateTransactionManager transactionManager(SessionFactory s) { 
    HibernateTransactionManager txManager = new HibernateTransactionManager(); 
    txManager.setSessionFactory(s); 
    return txManager; 
} 
}

我不知道發生了什麼

春季啓動正常配置其自身的DataSource和EntityManagerFactory的......您爲什麼選擇創建自己的，而不是提供什麼？這可能會干擾您的配置。也是第二臺服務器甚至能夠連接到服務器，即防火牆規則等 –

你是如何加載'db.properties'？。春天啓動的標準是['application.properties']（https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html#boot-features-external-配置簡檔特定的特性）。 –

編輯原始問題，我有一個HibernateConfiguration類，因爲我重構了從Spring MVC到Boot的應用程序。但該應用程序在服務器上工作，並一直工作... – besmart

1）當使用了Spring啓動時，您不應該包含其他Spring的依賴直接，但依靠引導自己的依賴管理。當使用提供的「初學者」時，您可以確保所有需要的庫都將包含在匹配的版本中。文檔：https://spring.io/guides/gs/spring-boot/#use-maven

2）調度指南不是一個Web應用程序，所以你可能在REST指南的pom.xml中有一些模糊的東西？

一個「好」 POM將有「彈簧引導起動網」（爲方便起見），或者包含在單獨列出啓動所有的依賴。只要檢查你是否有他們。還要確保在SpringApplication中包含@EnableAutoConfiguration。添加類中的對象陣列運行SpringApplication的run方法：SpringApplication.run（新對象[] {Application.class，ScheduledTasks.class}，參數）;

享受:)

對不起@Abdel，但我不明白你寫的所有內容。我用彈簧啓動工具製作了POM，添加了我需要的所有東西（hibernate，jackson，log4j等），這是實用程序給我的。我也有我的開始類用'@ SpingBootApplication'註解應用程序只是一個REST存儲庫，它啓動並公開一些REST服務。 – besmart

我有同樣的問題。補充一點：

在src /主/資源添加一個新的文件，名稱爲application.properties

spring.datasource.driverClassName=com.mysql.jdbc.Driver 
spring.datasource.url=jdbc:mysql://192.168.3.240:3306/SMARTPARK?useSSL=false 
spring.datasource.password=xxxxxxxxxxxxxxxx 
spring.datasource.username=parkuser 
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect 
spring.jpa.show-sql=true

在主類中刪除& HibernateConfiguration類放@EnableTransactionManagement註解。
