我尝试使用HSQLDB和spring JDBC模板。它工作正常,直到我使用Java 8的LocalDateTime类。
我有这段代码:
import org.hsqldb.jdbc.JDBCDataSource;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.init.ResourceDatabasePopulator;
import java.time.LocalDateTime;
public class Test
{
public static void main(String[] args) throws Exception
{
JDBCDataSource dataSource = new JDBCDataSource();
dataSource.setUser("SA");
dataSource.setPassword("");
dataSource.setUrl("jdbc:hsqldb:mem:db");
Resource resource = new ClassPathResource("/test.sql");
ResourceDatabasePopulator databasePopulator = new ResourceDatabasePopulator(resource);
databasePopulator.execute(dataSource);
JdbcTemplate template = new JdbcTemplate(dataSource);
template.update("INSERT INTO test VALUES (?)", LocalDateTime.now());
}
}
脚本如下所示:
CREATE TABLE test
(
datetime DATETIME NOT NULL,
);
当我尝试运行它时,我会得到例外:
org.hsqldb.HsqlException: incompatible data type in conversion
在app后端我使用LocalDateTime。我怎样才能做到这一点?
答案 0 :(得分:8)
您应该能够使用Timestamp.valueOf()
将LocalDateTime
转换为java.sql.Timestamp
来解决问题:
JdbcTemplate template = new JdbcTemplate(dataSource);
template.update("INSERT INTO test VALUES (?)", Timestamp.valueOf(LocalDateTime.now()));
