R2DBC ClassCastException Long无法强制转换为Int



我得到以下错误。我试着在Long和Int之间找到我做错的地方，但没有找到任何地方，任何想法？

H2配置

@Configuration
class H2Configuration {
@Bean
fun initializer(connectionFactory: ConnectionFactory): ConnectionFactoryInitializer {
val initializer = ConnectionFactoryInitializer()
initializer.setConnectionFactory(connectionFactory)
val populator = CompositeDatabasePopulator()
populator.addPopulators(ResourceDatabasePopulator(ClassPathResource("schema.sql")))
populator.addPopulators(ResourceDatabasePopulator(ClassPathResource("data.sql")))
initializer.setDatabasePopulator(populator)
return initializer
}
}

代理实体

@Table("agents")
data class AgentEntity(
@Id
@Column("id")
var id: Long?,
@Column("store_number")
var storeNumber: Int,
@Column("country")
var country: String,
@Column("name")
var name: String,
@Column("status")
var status: String,
@Column("last_update")
var lastUpdate: OffsetDateTime
)

代理假设

@Repository
interface AgentRepository : ReactiveCrudRepository<AgentEntity, Long> {
@Query("SELECT * FROM agents WHERE status = :status")
fun findAgentByStatus(status: String): Flux<AgentEntity>
@Query("select * from agents where id = :agentId ")
fun findByAgentId(agentId: Long): Flux<AgentEntity>
}

data.sql

INSERT INTO agents (id, store_number, country, name, status) VALUES (1, 5019, 'TH', 'devid', 'UP');
INSERT INTO agents (id, store_number, country, name, status) VALUES (2, 5019, 'TH', 'angle', 'DOWN');
INSERT INTO agents (id, store_number, country, name, status) VALUES (3, 5018, 'TH', 'nomad', 'UP');
INSERT INTO agents (id, store_number, country, name, status) VALUES (4, 5018, 'TH', 'iceberg', 'DOWN');

schema.sql

CREATE TABLE IF NOT EXISTS agents (
id SERIAL PRIMARY KEY,
store_number INTEGER,
country VARCHAR(5),
name VARCHAR(255),
status VARCHAR(10),
last_updated TIMESTAMP
);

AFAIK，如果使用spring boot<3.x，您应该更好地使用R2DBC的0.x版本，根据我的经验，spring boot 2.7.4和Oracle R2DBC 1.0.0的组合会导致相同的异常。将Oracle R2DBC从1.0.0更改为0.4.0解决了此问题。
