Spring数据Jpa JavaConfig

Question

我最近使用弹簧数据jpa在弹簧网络应用程序上工作

我遇到持久性配置问题：

@Configuration
@EnableTransactionManagement
@ComponentScan(basePackages = "com.servmed")
@PropertySource({ "/resources/hibernate.properties" })
@EnableJpaRepositories(basePackages = "com.servmed.repositories")

public class PersistenceConfig {

    @Autowired
    private Environment env;


    Properties jpaProperties() {
        return new Properties() {
            {
                setProperty("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));
                setProperty("hibernate.dialect", env.getProperty("hibernate.dialect")); //allows Hibernate to generate SQL optimized for a particular relational database.
                setProperty("hibernate.show_sql",env.getProperty("hibernate.show_sql"));
            }
        };
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory()
    {
        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setGenerateDdl(true);
        vendorAdapter.setShowSql(true);

        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setDataSource(dataSource());
        factory.setJpaVendorAdapter(vendorAdapter);
        factory.setJpaProperties(jpaProperties());
        factory.setPackagesToScan("com.servmed.models");

        //factory.setLoadTimeWeaver(new InstrumentationLoadTimeWeaver());
        return factory;
    }

    @Bean
    public PlatformTransactionManager transactionManager()
    {
        EntityManagerFactory factory = entityManagerFactory().getObject();
        return new JpaTransactionManager(factory);
    }

    @Bean
    public HibernateExceptionTranslator hibernateExceptionTranslator(){
        return new HibernateExceptionTranslator();
    }


    @Bean
    public DataSource dataSource() {
        BasicDataSource dataSource = new BasicDataSource();
        dataSource.setDriverClassName(env.getProperty("jdbc.driverClassName"));
        dataSource.setUrl(env.getProperty("jdbc.url"));
        dataSource.setUsername(env.getProperty("jdbc.user"));
        dataSource.setPassword(env.getProperty("jdbc.pass"));

        return dataSource;
    }
}

我收到此错误，我似乎无法找到错误：

Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor#0': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [com/servmed/configuration/PersistenceConfig.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory]]

PS：我注意到我添加到库中的hibernate实体管理器已被取消，我应该用其他东西替换吗？

Answer 1

不完全确定问题是什么，但我相信您的实体经理定义可能会在某处被破坏。

我使用的这个定义非常接近你的定义。看看。

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {

    LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
    emf.setDataSource(this.dataSource());
    emf.setPackagesToScan("com.servmed.models");
    emf.setPersistenceUnitName("MyPU");
    HibernateJpaVendorAdapter va = new HibernateJpaVendorAdapter();
    emf.setJpaVendorAdapter(va);
    Properties jpaProperties = new Properties();
    jpaProperties.put("hibernate.dialect", "org.hibernate.dialect.HSQLDialect");
    jpaProperties.put("hibernate.hbm2ddl.auto", "create");
    emf.setJpaProperties(jpaProperties);
    emf.afterPropertiesSet();
    return emf;
}
