SpringBoot應用程序運行正常，但休眠與MySQL相關的屬性不工作

Question

@Configuration 
    @EnableJpaRepositories(basePackages = 
    "com.gmt.user",entityManagerFactoryRef = 
    "userEntityManager",transactionManagerRef = "userTransactionManager") 

    public class UserConfig { 


@Bean 
@Primary 
public LocalContainerEntityManagerFactoryBean userEntityManager(){ 
    LocalContainerEntityManagerFactoryBean em= new LocalContainerEntityManagerFactoryBean(); 
    em.setDataSource(userDatasource()); 
    em.setPackagesToScan(new String[]{"com.gmt.user"}); 

    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter(); 
    em.setJpaVendorAdapter(vendorAdapter); 

    HashMap<String,Object> properties = new HashMap<String, Object>(); 
    properties.put("hibernate.hbm2ddl.auto","craete"); 
    properties.put("hibernate.dialect","org.hibernate.dialect.MySQL5Dialect"); 
    properties.put("hibernate.show_sql","true"); 
    em.setJpaPropertyMap(properties); 
    return em; 
} 

@Bean 
@Primary 
public DataSource userDatasource(){ 
    DriverManagerDataSource dataSource = new DriverManagerDataSource(); 
    dataSource.setDriverClassName("com.mysql.jdbc.Driver"); 
    dataSource.setUrl("jdbc:mysql://localhost:3306/schema_name"); 
    dataSource.setUsername("root"); 
    dataSource.setPassword("password12"); 
    return dataSource; 

} 

@Bean 
@Primary 
public PlatformTransactionManager userTransactionManager(){ 
    JpaTransactionManager jpaTransactionManager = new JpaTransactionManager(); 

    jpaTransactionManager.setEntityManagerFactory(userEntityManager().getObject()); 

    return jpaTransactionManager; 

} 

}

這裏是我的SpringBoot應用

@SpringBootApplication 
    @ComponentScan(basePackages = "com.gmt") 
    @EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, 
    HibernateJpaAutoConfiguration.class}) 
    public class Client { 
    public static void main(String[] args){ 
    SpringApplication.run(Client.class,args); 

    System.out.println(" ***** Inside Spring Boot Application ***** "); 


    } 
    } 

，這裏是我的pom.xml

而且我已經將模型類和相應的存儲庫放在同一個文件夾中。應用程序運行正常，沒有任何錯誤，但沒有連接到數據庫，也沒有在模式中創建表。請幫助我解決此問題。

Answer 1

你在這裏拼錯了hibernate.hbm2ddl.auto屬性值：

properties.put("hibernate.hbm2ddl.auto","craete"); 

它必須是create，但你必須把它設置爲craete。

Answer 2

在你的POM，如果您使用彈簧引導起動數據JPA沒有必要使用的<groupId>org.hibernate</groupId>的其他文物。 「spring-boot-starter-data-jpa」會將Hibernate作爲默認的JPA提供程序引入，這可能會引起依賴關係衝突，因此我也看到類似的問題。 所以你說沒有顯示錯誤？你調試過了嗎？

此外，在春季啓動youc的設置您的屬性：

spring.datasource.* 

春天開機JPA會隨時自動

要更改休眠特性，我們將使用前綴

`spring.jpa.properties.*` 

與休眠屬性名稱 在給定數據源URL的基礎上，spring boot可以自動識別數據源驅動程序類。所以我們不需要配置驅動類。
