java - 如何解决使用 Spring Boot 应用程序时的 PostgreSQL 问题

Question

我有一个由多个 Maven 模块构建的项目。这些模块包括清除、填充和验证 PostgreSQL 数据库内容的逻辑。

较低级别的模块都工作正常，但我的顶级 Spring Boot 应用程序当前由于以下错误而失败:

堆栈跟踪将我指向这一关键行:

org.postgresql.util.PSQLException: ERROR: column userrecord0_.created_by_user_uuid does not exist

失败的测试如下:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = CornerstoneApplication.class)
@WebAppConfiguration
public class CornerstoneApplicationTest {

@Test    
public void contextLoads() {  }
}

应用程序是:

@SpringBootApplication
public class CornerstoneApplication {
    public static void main(String[] args) {
        SpringApplication.run(CornerstoneApplication.class, args);
    }
}

看底层数据，userrecord文件中的第一条数据记录没有created_by_user_uuid，但是看实体记录，这个字段不是必填的

用户记录:

@Entity
@Table(name = "users")
public class UserRecord extends AbstractKeyedRecord implements Record {

    @Nonnull
    @Column(unique = true)
    private String userName;
    @Nonnull
    private String firstName;
    @Nonnull
    private String lastName;
<truncated>

抽象KeyedRecord:

@MappedSuperclass
public abstract class AbstractKeyedRecord extends AbstractRecord {
    @Id
    @org.hibernate.annotations.Type(type = "pg-uuid")
    private UUID id;
<truncated>

摘要记录:

@MappedSuperclass
public abstract class AbstractRecord implements Serializable, Record {
@Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")
private DateTime createdDate;
@org.hibernate.annotations.Type(type = "pg-uuid")
private UUID createdByUserUuid;

@Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")
private DateTime lastUpdatedDate;
@org.hibernate.annotations.Type(type = "pg-uuid")
private UUID lastUpdatedUserUuid;

public AbstractRecord() {
}
<truncated>

记录:

public interface Record {}

可能最令人沮丧的事情是我以前曾进行过此工作，但最近从 xml 配置文件转移到使用配置类，并且从那以后 ApplicationTest 就不再工作了。

所以，我的问题是有人可以建议我可以采取的步骤来解决这个问题吗？

Answer 1

我认为您正在连接到没有“created_by_user_uuid”列的其他数据库。特别是因为它使用 XML 配置。
检查您的数据库连接配置。您可以将数据库连接密码设置为错误的密码，以确保您确实连接到配置的数据库。
