java - 2.0.9 和 2.1.0 之间的 Spring Boot eclipselink ddl 自动生成问题

转载作者：行者123 更新时间：2023-11-30 05:21:33

使用 Spring boot 2.1.0 RELEASE 创建了新项目，我的 pom.xml 包含此

..
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
    <version>${spring.boot.version}</version>
</dependency>
<dependency>
    <groupId>org.eclipse.persistence</groupId>
    <artifactId>eclipselink</artifactId>
    <version>2.6.3</version>
</dependency>
<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.1.Final</version>
</dependency>
..

我使用 LocalContainerEntityManagerFactoryBean 配置它，但没有 application.properties 文件:

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(dataSource());
    em.setPackagesToScan("com.xxxx.api.model");
    em.setPersistenceUnitName("xxxx-pu");
    Properties prop = new Properties();
    prop.putAll(getVendorProperties());

    em.setJpaVendorAdapter(vendorAdapter);
    em.setJpaProperties(prop);
    return em;
}

protected Map<String, String> getVendorProperties() {
    final Map<String, String> ret = new HashMap<>();
    ret.put(PersistenceUnitProperties.BATCH_WRITING, BatchWriting.JDBC);
    ret.put(PersistenceUnitProperties.WEAVING, "false");
    ret.put(PersistenceUnitProperties.LOGGING_LEVEL, "ALL");
    ret.put(PersistenceUnitProperties.DDL_GENERATION, PersistenceUnitProperties.DROP_AND_CREATE);
    return ret;
}

我在 com.xxxx.api.model

中有一个非常简单的类 Account.java

@Data
@AllArgsConstructor
@NoArgsConstructor
@Entity
@Table(name="ACCOUNT")
public class Account{
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @XmlAttribute
    @Basic(optional = false)
    @Column(name = "ID", nullable = false)
    private Long id;

    private String username;

    private String password;

}

通过使用这些配置和类，我无法自动生成 ddl。

输出日志如下所示:

如果我将 pom.xml 的 spring.boot.version 更改为 2.0.9.RELEASE，它可以正常工作并生成 ACCOUNT 表格也是如此。

最佳答案

我发现了这个问题。从 Spring Boot 2.1.0.RELEASE 开始，Eclipselink 的持久性单元部署仅在我们点击任何 REST Controller 端点后才会发生。因此，我更改了代码以在应用程序准备就绪后对其进行初始化。这是一种很古怪的方式，但很有效。

public class JPAConfig implements ApplicationContextAware { 

// ...

    private ApplicationContext context;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        this.context = applicationContext;
    }

    @EventListener(ApplicationReadyEvent.class)
    public void startup() {
        EntityManager bean = this.context.getBean(EntityManager.class);
        try {
            bean.clear();
        }catch (Exception e){
            e.printStackTrace();
        }
    }
//...
}

运行此命令后，我得到如下日志:
