主要错误指向我的 AuctionWebApplication.java 类，这是我的配置 -
The main error point to my AuctionWebApplication.java class which is my configuration -
@SpringBootApplication
@ComponentScan
@EnableJpaRepositories("All")
@EntityScan("All")
public class AuctionWebApplication extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(AuctionWebApplication.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(AuctionWebApplication.class, args);
}
@Bean
DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUrl("jdbc:mysql://localhost:3306/auctiondb?zeroDateTimeBehavior=convertToNull");
dataSource.setUsername("root");
dataSource.setPassword("toor");
return dataSource;
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource) {
LocalContainerEntityManagerFactoryBean entityManager = new LocalContainerEntityManagerFactoryBean();
entityManager.setDataSource(dataSource);
entityManager.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
entityManager.setPackagesToScan("All");
Properties jpaProperties = new Properties();
jpaProperties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
jpaProperties.setProperty("hibernate.hbm2ddl.auto", "update");
jpaProperties.setProperty("hibernate.id.new_generator_mappings", "false");
entityManager.setJpaProperties(jpaProperties);
return entityManager;
}
}
特别是这一行 -
entityManager.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
我的想法是它是一个依赖错误，但我在 POM 中找不到任何问题-
My thinkinking is that its a dependency error but i cant find any problems in POM-

推荐答案
如聊天中所讨论的 https://chat.stackoverflow.com/rooms/139379/discussion-between-amitk-and-hazardaguess ，mvn clean package 命令解决了这个问题，看起来像 <最初缺少 HibernateEntityManagerFactory 类的强>依赖项，因为 OP 没有使用 maven 的自动刷新功能.当 OP 运行 mvn clean package 命令时，它已经下载了所需的 jar，从而解决了问题.
As discussed in the chat https://chat.stackoverflow.com/rooms/139379/discussion-between-amitk-and-hazardaguess , mvn clean package command resolved the issue, it looks like the dependency of HibernateEntityManagerFactory class was missing initially, As OP was not using the auto-refresh feature of maven. and when OP ran mvn clean package command,it had downloaded the required jar, which resolved the issue.
