java - org.h2.jdbc.JdbcSQLException：找不到模式“MYAPP”；SQL 语句

Question

我正在尝试将 H2 数据库与 sprint junit 测试一起使用，如下所示：

1- SpringTestingConfig：

@Configuration
@ComponentScan(basePackages = "com.myapp.data", excludeFilters = { @Filter(Configuration.class) })
@PropertySource("classpath:/test.properties")
@Profile("test")
public class SpringTestingConfig {
   @Bean
   public DataSource dataSource() {
      DriverManagerDataSource dataSource = new DriverManagerDataSource();
      dataSource.setDriverClassName("org.h2.Driver");
      dataSource.setUrl("jdbc:h2:mem:test;MODE=Mysql;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE;INIT=CREATE SCHEMA IF NOT EXISTS TEST");
      dataSource.setUsername("sa");
      dataSource.setPassword("");
      return dataSource;
   }
}

2-我的测试类：

@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({ WebContextTestExecutionListener.class,
        DependencyInjectionTestExecutionListener.class,
        DirtiesContextTestExecutionListener.class,
        TransactionalTestExecutionListener.class })
@ActiveProfiles("test")
@DirtiesContext
@ContextConfiguration(loader = AnnotationConfigContextLoader.class, classes = {
        SpringConfig.class, SpringTestingConfig.class,
        SpringLocalContainerJPAConfig.class, CustomConfiguration.class })
public class MyTestClass{

}

我的数据库表是在运行时使用休眠创建的，当我尝试运行测试时，出现以下异常：

org.springframework.orm.hibernate3.HibernateJdbcException: JDBC exception on Hibernate data access: SQLException for SQL [/* select generatedAlias0 from User as generatedAlias0 */ select user0_.id as id1_8_, user0_.jpa_version as jpa2_8_, user0_.AccountActivated as AccountA3_8_, user0_.AccountActivationDate as AccountA4_8_, user0_.IsAdmin as IsAdmin5_8_, user0_.Bio as Bio6_8_, user0_.birthMonth as birthMon7_8_, user0_.CashGivingBalance as CashGivi8_8_, user0_.CashReceivedBalance as CashRece9_8_, user0_.CompanyGID as Company28_8_, user0_.AccountCreatedDate as Account10_8_, user0_.dayOfBirthday as dayOfBi11_8_, user0_.DeletionWarningDate as Deletio12_8_, user0_.Dept as Dept13_8_, user0_.Email as Email14_8_, user0_.FirstName as FirstNa15_8_, user0_.HireDate as HireDat16_8_, user0_.is_active as is17_8_, user0_.LastLogin as LastLog18_8_, user0_.LastName as LastNam19_8_, user0_.LastSatisfactionSurveyDate as LastSat20_8_, user0_.Locale as Locale21_8_, user0_.MPath as MPath22_8_, user0_.MTDRewards as MTDRewa23_8_, user0_.Password as Passwor24_8_, user0_.PersonalityType as Persona25_8_, user0_.Title as Title26_8_, user0_.YTDRewards as YTDRewa27_8_ from myapp.User user0_]; SQL state [90079]; error code [90079]; could not prepare statement; nested exception is org.hibernate.exception.GenericJDBCException: could not prepare statement

更新：在我的 test.properties 我有以下键

hibernate.default_schema=Test

Answer 1

在你的 SQL 最后你有

from myapp.User user0_

不应该

from TEST.User user0_ ?

修复它替换：

@Value("${hibernate.default_schema:myapp}")
private String defaultSchema;

和

@Value("${hibernate.default_schema}")
private String defaultSchema;

并使用：

dataSource.setUrl("jdbc:h2:mem:test;MODE=Mysql;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE;INIT=CREATE SCHEMA IF NOT EXISTS MYAPP");

希望有帮助

Answer 2

当你配置你的数据源时，也会提到 runscript url。

句法：

dataSource.setUrl("jdbc:h2:mem:cpq_testdb;INIT=create schema if not exists my_database\\;runscript from '**classpath:scripts/create.sql**';DB_CLOSE_DELAY=-1");

create.sql 应该在你的包中的某个地方 test/resource/scripts/create.sql

创建.sql：

use my_database;
create schema if not exists your_schema_name;

Answer 3

正如@faromisiek 所提到的，您有一个模式名称mispatch - 您希望它是“TEST”，但由于某种原因，hibernate 使用了“myapp”。检查您的休眠配置（使用纯休眠还是 JPA？）。

你可以设置hibernate.default_schema属性来明确告诉它使用哪个模式。

您的数据源的 JDBC url 可以更改如下：

dataSource.setUrl("jdbc:h2:mem:test;MODE=Mysql;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE;INIT=CREATE SCHEMA IF NOT EXISTS TEST;SCHEMA=TEST");

Answer 4

在我的情况下，问题是由于我没有在 java 中设置 h2 用户名和密码。不幸的是，Spring 没有向我显示任何错误，因此很难弄清楚。将此行添加到 dataSource 方法帮助我解决了这个问题：

dataSource.setUsername("sa");
dataSource.setPassword("");

我知道这不是您的情况，您设置了用户名和密码
