自動創建表在Spring中失敗JPA

我有一個Spring JPA，Hibernate，MySQL的問題。我有一個實體（Nom.java）和存儲庫（公共接口NomRepository擴展JpaRepository）。他們創建並注入得很好。自動創建表在Spring中失敗JPA

問題是，當我試圖通過存儲庫的save方法保存記錄時，spring會抱怨「Table」不存在「。的確我在MySQL看不到這張表。我試過了hibernate.hbm2ddl.auto的不同值，但沒有幫助。

我使用XML-less配置BTW。

這裏的配置文件：

package ru.interosite.awp.config; 

import java.util.Properties; 
import javax.sql.DataSource; 
import org.springframework.boot.autoconfigure.EnableAutoConfiguration; 
import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.ComponentScan; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.data.jpa.repository.config.EnableJpaRepositories; 
import org.springframework.jdbc.datasource.DriverManagerDataSource; 
import org.springframework.orm.jpa.JpaVendorAdapter; 
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean; 
import org.springframework.orm.jpa.vendor.Database; 
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter; 

@Configuration 
@ComponentScan("ru.interosite.awp") 
@EnableAutoConfiguration 
public class AppConfiguration { 

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

    @Bean 
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, JpaVendorAdapter jpaVendorAdapter) { 
     LocalContainerEntityManagerFactoryBean lef = new LocalContainerEntityManagerFactoryBean(); 
     lef.setPersistenceUnitName("my_pu"); 
     lef.setPackagesToScan("ru.interosite.awp.data"); 
     lef.setDataSource(dataSource); 
     lef.setJpaVendorAdapter(jpaVendorAdapter); 
     lef.setJpaProperties(getJpaProperties()); 
     return lef; 
    } 

    @Bean 
    public JpaVendorAdapter jpaVendorAdapter() { 
     HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter(); 

     jpaVendorAdapter.setDatabase(Database.MYSQL); 
     jpaVendorAdapter.setGenerateDdl(true); 
     jpaVendorAdapter.setShowSql(true); 
     jpaVendorAdapter.setDatabasePlatform("org.hibernate.dialect.MySQL5Dialect"); 

     return jpaVendorAdapter; 
    } 

    private Properties getJpaProperties() { 
     return new Properties() { 
      { 
       setProperty("hibernate.hbm2ddl.auto", "update"); 
       setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect"); 
       setProperty("hibernate.show_sql", "true"); 
       setProperty("hibernate.format_sql", "true"); 
      } 
     }; 
    } 
}

下面是如何啓動的應用程序：

package ru.interosite.awp; 

import java.awt.Font; 
import javax.swing.UIManager; 
import org.slf4j.Logger; 
import org.slf4j.LoggerFactory; 
import org.springframework.boot.SpringApplication; 
import org.springframework.context.ApplicationContext; 
import ru.interosite.awp.config.AppConfiguration; 
import ru.interosite.awp.gui.UIUtils; 

public class Boot { 

    private static final Logger LOGGER = LoggerFactory.getLogger(Boot.class); 

    public static void main(String[] args) 
    { 

     UIUtils.setUIFont(new javax.swing.plaf.FontUIResource(Font.SANS_SERIF, Font.PLAIN, 16)); 

     try { 
      String lafClassName = UIManager.getSystemLookAndFeelClassName(); 
      UIManager.setLookAndFeel(lafClassName); 
     } catch (Exception e) { 
      LOGGER.debug(e.getMessage()); 
     }   

     ApplicationContext ctx = SpringApplication.run(AppConfiguration.class, args); 
     ((Runner)ctx.getBean("runner")).start(); 
    }  
}

這是我的pom.xml：

好吧，最後我發現瞭如何解決它。 1）首先，我搬到AppConfiguration類頂級包，ru.interosite.awp在我的情況 2）其次，我改變了註解是：

@Configuration 
@ComponentScan 
@EnableJpaRepositories 
public class AppConfiguration {...

似乎@EnableAutoConfiguration註解把事情搞亂。我不知道，如果它是一個錯誤或功能。看起來實際上是一個彈簧引導的錯誤。

如果你想表到被創建，您必須將hibernate.hbm2ddl.auto屬性設置爲create。以下是hibernate.hbm2ddl.auto的可能值：

驗證：驗證架構，不更改數據庫。
更新：更新架構。
create：創建模式，破壞以前的數據。
create-drop：在會話結束時刪除架構。

此外，請檢查您的數據庫網址是否正確。

[更新]不要忘記爲spring定義事務管理器。

@Bean 
    public PersistenceAnnotationBeanPostProcessor persistenceAnnotationBeanPostProcessor() 
    { 
    PersistenceAnnotationBeanPostProcessor persistenceAnnotationBeanPostProcessor = new PersistenceAnnotationBeanPostProcessor(); 
    return persistenceAnnotationBeanPostProcessor; 
    }

你說得對。正如你所看到的，我將hibernate.hbm2ddl.auto設置爲在getJpaProperties方法中「更新」。但它沒有幫助。 – Cyrusmith

我也嘗試過「創建」。沒有運氣。 – Cyrusmith

persistenceAnnotationBeanPostProcessor也沒有幫助。 Plz看到我的答案。 – Cyrusmith

我交換到M5彈簧引導起動XXX罐子，現在我看到我的表獲得創建

這是我的應用程序類（這是我在春天開機，以便第一次嘗試...）

需要昌二方法和刪除的GetProperties（）方法：

@Bean 
public LocalContainerEntityManagerFactoryBean entityManagerFactory(
     DataSource dataSource, JpaVendorAdapter jpaVendorAdapter) { 
    LocalContainerEntityManagerFactoryBean lef = new LocalContainerEntityManagerFactoryBean(); 
    lef.setDataSource(dataSource); 
    lef.setJpaVendorAdapter(jpaVendorAdapter); 
    lef.setPackagesToScan("com.spring.domain"); 
    return lef; 
} 

@Bean 
public JpaVendorAdapter jpaVendorAdapter() { 
    HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter(); 
    hibernateJpaVendorAdapter.setShowSql(true); 
    hibernateJpaVendorAdapter.setGenerateDdl(true); //Auto creating scheme when true 
    hibernateJpaVendorAdapter.setDatabase(Database.H2);//Database type 
    return hibernateJpaVendorAdapter; 
}

的一點是：

hibernateJpaVendorAdapter.setGenerateDdl(true);
