Question

在Tomcat上部署我的应用程序后出现问题。我使用的是Spring 5和Hibernate 5.我通过Hibernate Tools导出数据库模型。我的错误看起来像Hibernate模型之间的映射问题。

在我的实体类中，我从库中导入javax.persistence：

[Maven: org.hibernate.javax.persistence:hibernate-jpa-2.1-api:1.0.0.Final] javax.persistence public @interface Entity

问题：我的Hibernate模型代码出了什么问题？

Answer 1

setAnnotatedClasses() ...设置带注释的类。因此，每次调用它时，都会用新的类替换先前设置的类。将其称为一次，并将带注释的类的全部作为参数传递。

Answer 2

看看这个配置：

@Configuration
@EnableTransactionManagement
@PropertySource(value = { "classpath:myproject.properties" })
public class HibernateConfiguration {

@Autowired
private Environment env;

@Bean
public SessionFactory  sessionFactory() {
    LocalSessionFactoryBuilder builder = new LocalSessionFactoryBuilder(dataSource());
    builder.scanPackages("com.example.model").addProperties(hibernateProperties());
    return builder.buildSessionFactory();
}

@Bean
public DataSource dataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(env.getRequiredProperty("jdbc.driverClassName"));
    dataSource.setUrl(env.getRequiredProperty("jdbc.url"));
    dataSource.setUsername(env.getRequiredProperty("jdbc.username"));

注意builder.scanPackages（“com.example.model”），这将为您提供更好的方法来扫描实体，您不再需要手动添加它们。

在您的配置中，错误可能是由于实体注册订单。因此，使用之前的配置让我们开始工作。

PD：您可以使用@Value从属性文件

设置属性值

Answer 3

如果您正确检查日志，您会看到：引起：org.hibernate.AnnotationException：使用@OneToMany或@ManyToMany定位未映射的类：com.example.model.Wydzialy.referaties [com.example.model.Referaty]

在您的代码中

类Wydzialy

@OneToMany(fetch = FetchType.LAZY, mappedBy = "wydzialy")
public Set<Sprawy> getSprawies() {
    return this.sprawies;
}

类Referaty

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "ID_WYDZ")
public Wydzialy getWydzialy() {
    return this.wydzialy;
}

You need to replace Set<Sprawy> with Set<Wydzialy>具有有效的双向关系。

同样在 @ManyToOne（fetch = FetchType.LAZY）

FetchType.LAZY没有意义，因为ManyToOne是单值关联。
