我得到奇怪的錯誤：數據轉換出錯轉換
INFO: Rolled back transaction after test execution for test context [[email protected] testClass = DaoTest, testInstance = [email protected], testMethod = [email protected], testException = javax.persistence.PersistenceException: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.5.1.v20130918-f2b9fc5): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: org.h2.jdbc.JdbcSQLException: Data conversion error converting "2016-04-25"; SQL statement:
SELECT state, count(*) FROM table WHERE created_on >= ? - 1 AND created_on < ? + 1 GROUP BY state [22018-191]
Error Code: 22018
Call: SELECT state, count(*) FROM table WHERE created_on >= ? - 1 AND created_on < ? + 1 GROUP BY state
bind => [2 parameters bound]
Query: DataReadQuery(sql=" SELECT state, count(*) FROM table WHERE created_on >= ? - 1 AND created_on < ? + 1 GROUP BY state "), mergedContextConfiguration = [[email protected] testClass = DaoTest, locations = '{classpath:test.xml}', classes = '{}', contextInitializerClasses = '[]', activeProfiles = '{}', contextLoader = 'org.springframework.test.context.support.DelegatingSmartContextLoader', parent = [null]]]
我的查詢是：
SELECT state, count(*)
FROM table
WHERE created_on >= ?1 - 1 AND created_on < ?2 + 1
GROUP BY state
其他細節重現：

我Dao.class是
package test;
import java.util.Date;
import java.util.List;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.persistence.Query;
import javax.persistence.TemporalType;
import org.springframework.stereotype.Repository;
@Repository
public class Dao {
@PersistenceContext
protected EntityManager em;
public void getCount(Date fromDate, Date toDate) {
StringBuilder sb = new StringBuilder();
sb.append(" SELECT state, count(*) ");
sb.append(" FROM table ");
sb.append(" WHERE created_on >= ?1 - 1 AND created_on < ?2 + 1 ");
sb.append(" GROUP BY state ");
Query q = em.createNativeQuery(sb.toString());
q.setParameter(1, fromDate, TemporalType.DATE);
q.setParameter(2, toDate, TemporalType.DATE);
List list = q.getResultList();
}
}
我DaoTest類是：
package test;
import java.util.Date;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:test.xml"})
public class DaoTest extends AbstractTransactionalJUnit4SpringContextTests {
@Autowired
Dao dao;
@Test
public void testQuery() {
Date now = new Date();
dao.getCount(now, now);
}
}
我的配置文件如下：
的persistence.xml（SRC /測試/ resources/META-INF /）

ddl.sql

dml.sql

insert into TABLE (ID,CREATED_ON,state)

另外我添加新的測試（不em和使用JdbcTempltate），我有類似的問題：
@Autowired
DataSource dataSource;
public void getCountJdbc(Date fromDate, Date toDate) {
JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
jdbcTemplate.queryForList(getQuery(), fromDate, toDate);
}
其中getQuery()返回相同的查詢和所述錯誤是：
org.springframework.dao.DataIntegrityViolationException: PreparedStatementCallback; SQL [ SELECT state, count(*) FROM table WHERE created_on >= ?1 - 1 AND created_on < ?2 + 1 GROUP BY state ]; Data conversion error converting "2016-04-26 09:14:46.663"; SQL statement:
