java - 无法启动组件 [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/AuctionWebsite]]

Question

在尝试运行我的项目时，我陷入了一些困惑，收到了如下所示的错误列表。

第一个错误如下所示-

主要错误指向我的 AuctionWebApplication.java 类，这是我的配置 -

@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 -

Answer 1

正如聊天中所讨论的 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HibernateEntityManagerFactory类的依赖最初丢失了，作为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，这解决了问题。
