大家早上好
我正在使用HSQLDB使用JUnit对项目的持久层进行单元测试。该项目正在使用带有Hibernate + JPA的Spring。我正在使用Spring的SimpleJdbcInsert在数据库中插入一些数据以进行测试。但是,每当我尝试插入某些内容时,我都会得到:org.hsqldb.HsqlException: violación del restricción de integridad: restricción ('check') NOT NULL; SYS_CT_10137 table: PICTURE column: PICTURE_ID
如下所示:
org.springframework.dao.DataIntegrityViolationException: PreparedStatementCallback; SQL [INSERT INTO picture (DATA, MIME_TYPE, NAME, SIZE) VALUES(?, ?, ?, ?)]; violación del restricción de integridad: restricción ('check') NOT NULL; SYS_CT_10137 table: PICTURE column: PICTURE_ID; nested exception is java.sql.SQLIntegrityConstraintViolationException: violación del restricción de integridad: restricción ('check') NOT NULL; SYS_CT_10137 table: PICTURE column: PICTURE_ID

这是我的测试(insertPatient()
失败):
@Test
public void testCreateAppointmentSuccessfully() {
cleanAllTables();
insertPatient();
... some code ...
}
insertPatient
功能(insertPicture()
失败的地方:]]
private void insertPatient() { insertUser(); ... some code ... } private void insertUser() { insertPicture(); ... some code ... } private void insertPicture() { Map<String, Object> map = new HashMap<>(); map.put("data", IMG_DATA); map.put("mime_type", MIME_TYPE); map.put("size", IMG_SIZE); map.put("name", PICTURE); pictureJdbcInsert.execute(map); }
SimpleJdbcInsert pictureJdbcInsert
实例通过以下方法设置:
@Before public void setUp(){ this.pictureJdbcInsert = new SimpleJdbcInsert(this.ds) .withTableName(PICTURES_TABLE) // private static final String PICTURES_TABLE = "picture"; .usingGeneratedKeyColumns("picture_id"); ... some code ... }
测试类以
@Sql(scripts = "classpath:sql/schema.sql")
标注为schema.sql
:
create table if not exists picture ( picture_id identity not null constraint picture_pk primary key, name varchar(1023), mime_type varchar(255) not null, size bigint not null default 0, data varbinary(65535) not null ); ... some more tables ...
如您所见,我不是手动放置密钥。我期望
usingGeneratedKeyColumns
方法会自动为我生成它。从stacktrace我知道这是试图执行以下查询:INSERT INTO picture (DATA, MIME_TYPE, NAME, SIZE) VALUES(?, ?, ?, ?)
,其中?
被映射中的相应值替换,但是失败了,因为没有为picture_id
指定值。我不知道这种情况是否会发生,因为schema.sql
文件指定picture_id
的类型为identity
,这意味着它是自动生成的,默认情况下是从0开始且以1为增量。
我一直在尝试并寻找解决方案,但是一切都表明这应该可行。
大家早上好,我正在使用HSQLDB使用JUnit对项目的持久层进行单元测试。该项目正在使用带有Hibernate + JPA的Spring。我正在使用Spring的SimpleJdbcInsert插入一些...
[使用usingGeneratedKeyColumns()
方法时,似乎必须使用相应的方法executeAndReturnKey()
而不是execute()
来在插入时自动生成密钥。使用execute
方法时,您需要在参数映射中提供picture_id
列和值。
以上是关于SimpleJdbcInsert由于自动生成的ID(HSQLDB)为空而无法插入的主要内容,如果未能解决你的问题,请参考以下文章
