我的数据库中有类似字段的表Product：

@Transient
private Map<Locale, String> description = new HashMap<>();

description在类中定义ProductLocalization。

在我添加columnDefinition = "LONGTEXT"到

@Column(name = Product.COLUMN_DESCRIPTION, columnDefinition = "LONGTEXT")
private String description;

在该课程中，我可以根据需要设置超过 255 分的描述，但是我的 2 个测试在productDao.saveAndFlush(product)at之前开始失败product.setDescription(descriptions)，重要的是，当我在应用程序中执行该操作时，而不是在测试中一切正常，只测试导致问题

saveAndFlush()是我从包中得到的方法org.springframework.data.jpa.repository

两个测试中的错误相同：

javax.persistence.PersistenceException: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.4.0.v20120608-r11652): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLSyntaxErrorException: user lacks privilege or object not found: PRODUCT_LOCALIZED
Error Code: -5501
Call: INSERT INTO product_localized (description, entity_id, language) VALUES (?, ?, ?)
    bind => [angielski, 3, en]
Query: InsertObjectQuery(ProductLocalization{description=angielski})
    at org.eclipse.persistence.internal.jpa.EntityManagerImpl.flush(EntityManagerImpl.java:804)

这是测试代码：

 @Test
public void testMultilingualCreate() {
    // Given
    String polish = "polski", english = "angielski";
    Product product = new Product();
    product.setName("Product name");
    Map<Locale, String> descriptions = new HashMap<>(); 
    descriptions.put(Locale.ENGLISH, english);
    descriptions.put(Messages.POLISH, polish);

    // When
    product.setDescription(descriptions);
    Product p = productDao.saveAndFlush(product);
    product = productDao.findOne(p.getId());

    // Then
    assertEquals(polish, product.getDescription(Messages.POLISH));
    assertEquals(english, product.getDescription(Locale.ENGLISH));
}

和

@Test
public void testMultilingualUpdate() {
    // Given
    String polish = "polski", english = "angielski", english2 = "another english description";
    Product product = new Product();
    product.setName("Product name");
    Map<Locale, String> descriptions = new HashMap<>(); 
    descriptions.put(Locale.ENGLISH, english);
    descriptions.put(Messages.POLISH, polish);

    // When
    product.setDescription(descriptions);
    product = productDao.saveAndFlush(product);
    assertEquals(english, product.getDescription(Locale.ENGLISH));
    descriptions.put(Locale.ENGLISH, english2);
    product.setDescription(descriptions);
    product = productDao.saveAndFlush(product);

    // Then
    assertEquals(polish, product.getDescription(Messages.POLISH));
    assertEquals(english2, product.getDescription(Locale.ENGLISH));
}

这里有什么问题我该如何解决？
