java数据转换错误转换
我发现了一个奇怪的错误：
INFO: Rolled back transaction after test execution for test context [TestContext@1b1cfb87 testClass = DaoTest, testInstance = test.DaoTest@821330f, testMethod = testQuery@DaoTest, 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 = [MergedContextConfiguration@6f43c82 testClass = DaoTest, locations = '{classpath:test.xml}', classes = '{}', contextInitializerClasses = '[]', activeProfiles = '{}', contextLoader = 'org.springframework.test.context.support.DelegatingSmartContextLoader', parent = [null]]]
我的问题是：
SELECT state, count(*)
FROM table
WHERE created_on >= ?1 - 1 AND created_on < ?2 + 1
GROUP BY state
要复制的其他详细信息：
我和pom有一个maven项目。xml格式：

我的刀。班级是
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();
}
}
我的测试课程是：
package test;
import java.util.Date;

import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;

@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：
坚持。xml（src/test/resources/META-INF/）

此外，我添加了新的测试（没有em并使用JDBCTemplate），我也遇到了类似的问题：
@Autowired
DataSource dataSource;
public void getCountJdbc(Date fromDate, Date toDate) {
JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
jdbcTemplate.queryForList(getQuery(), fromDate, toDate);
}
其中getQuery()返回相同的查询，错误为：
