Spring - 配置Hibernate Jpa的问题

标签： java spring hibernate spring-mvc jpa

我从Spring Boot 1.5.9迁移到正常的Spring项目。

在application.properties我已添加

spring.autoconfigure.exclude[0]=org.springframework.boot.autoconfigure.thymeleaf.ThymeleafAutoConfiguration
spring.autoconfigure.exclude[1]=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
spring.autoconfigure.exclude[2]=org.springframework.boot.autoconfigure.h2.H2ConsoleAutoConfiguration
spring.autoconfigure.exclude[3]=org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration

我有一个配置类

@Configuration
public class HibernateJpaConfig {

private Map<String, String> properties = new HashMap<String, String>();

public HibernateJpaConfig() {
    properties.put("hibernate.hbm2ddl.auto", "create-drop");
}

@Bean
@Primary
public DataSource dataSource(){
    DataSource dataSource = new org.apache.tomcat.jdbc.pool.DataSource();
    dataSource.setDriverClassName("org.h2.Driver");
    dataSource.setUrl("jdbc:h2:mem:testdb");
    dataSource.setUsername("sa"); dataSource.setPassword("");
    return dataSource;
}

@Autowired
private DataSource dataSource;

@Autowired(required = false)
private PersistenceUnitManager persistenceUnitManager;

@Bean
public PlatformTransactionManager transactionManager() {
    return new JpaTransactionManager();
}

@Bean
public JpaVendorAdapter jpaVendorAdapter() {
    AbstractJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
    adapter.setShowSql(false);
    adapter.setDatabase(Database.H2);
    adapter.setDatabasePlatform("H2");
    adapter.setGenerateDdl(true);
    return adapter;
}

@Bean
public EntityManagerFactoryBuilder entityManagerFactoryBuilder(JpaVendorAdapter jpaVendorAdapter) {
    EntityManagerFactoryBuilder builder = new EntityManagerFactoryBuilder(
            jpaVendorAdapter, properties,
            this.persistenceUnitManager);
    builder.setCallback(null);
    return builder;
}

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(EntityManagerFactoryBuilder factoryBuilder) {
    Map<String, Object> vendorProperties = new LinkedHashMap<String, Object>();
    vendorProperties.putAll(properties);

    return factoryBuilder.dataSource(this.dataSource).packages("com.fabio.springmvc.domain")
            .properties(vendorProperties).jta(false).build();
}

}

当我运行项目时，我遇到以下错误（我已添加警告，因为它似乎与问题相关）

配置类基于Spring boot 1.3的课程，这里我使用的是1.5.9，我不知道为什么会遇到这个问题。

编辑客户重复列

@Entity
public class Customer extends AbstractDomainClass{

private String firstName;
private String lastName;
private String email;
private String phoneNumber;
@Embedded
private Address billingAddress;
@Embedded
private Address shippingAddress;
// getters setters
}

地址类

@Embeddable
public class Address {

private String addressLine1;
private String addressLine2;
private String city;
private String state;
private String zipCode;
// getters setters
}

1 个答案:

答案 0 :(得分：2)

出现此问题是因为您具有以下映射：

@Entity
public class Customer extends AbstractDomainClass {
    //other attributes...
    @Embedded
    private Address billingAddress;
    @Embedded
    private Address shippingAddress;
}

在这里，Hibernate将尝试做的是在表的列中映射@Embedded类的属性。也就是说，它会将Address#addressLine1从属性Address billingAddress映射到表addressLine1中的列customer。属性billingAddress和类Address的其他字段也会发生类似情况。然后，它会对Address shippingAddress执行相同操作，也就是说，它会将Address#addressLine1的{​​{1}}映射到表shippingAddress中的列addressLine1。这是例外的原因。

由于这更像是设计问题，而不是代码中的问题，我建议采用一些方法来解决它。

  1. 在表格中为所有字段添加不同的列，并将每个列映射到类中的特定属性。这是一个基本的例子：

    你桌子的DDL（使用我能想到的最常见的sql）。

    customer

    使用CREATE TABLE customer ( id INT NOT NULL, billingAddressLine1 VARCHAR(200) NOT NULL, shippingAddressLine1 VARCHAR(200) NOT NULL, -- other columns... PRIMARY KEY(id) ); 的{​​{1}}属性的Hibernate映射：

    @Embedded

  2. 不使用@AttributeOverrides表中的列，而是使用名为@Entity public class Customer extends AbstractDomainClass { //other attributes... @Embedded @AttributeOverrides( @AttributeOverride( name = "addressLine1", column = @Column(name = "billingAddressLine1"), ) //do similar for the other attributes... ) private Address billingAddress; @Embedded @AttributeOverrides( @AttributeOverride( name = "addressLine1", column = @Column(name = "shippingAddressLine1") ) //do similar for the other attributes... ) private Address shippingAddress; } 的单独表和名为customer的列（或您喜欢的名称）来存储地址顾客。

    你桌子的DDL（使用我能想到的最常见的sql）。

    address

    类的Hibernate映射（不是addressType）：

    CREATE TABLE customer (
    id INT NOT NULL,
    -- other columns...
    PRIMARY KEY(id)
);

CREATE TABLE address (
    id INT NOT NULL,
    addressType INT NOT NULL,
    customer_id INT NOT NULL,
    addressLine1 VARCHAR(200) NOT NULL,
    -- other columns...
    PRIMARY KEY(id),
    FOREIGN KEY (customer_id) REFERENCES customer(id)
);
