【中文标题】HSQLDB + JUnit + Hibernate：java.sql.SQLException：无效的模式名称

【英文标题】：HSQLDB + JUnit + Hibernate: java.sql.SQLException: invalid schema name

【问题描述】：

我想用 JUnit 和 Hibernate 运行内存数据库 HSQLDB 的测试，但是当方法尝试将更改提交到 DB 时，出现此异常：（无 Spring 框架）

Caused by: java.sql.SQLException: invalid schema name: SRH in statement [select liquidacio0_.idLiquidacion as idLiquid1_180_0_, liquidacio0_.fkEstado as fkEstado180_0_, liquidacio0_.FECHA_LIQ as FECHA3_180_0_, liquidacio0_.DIAS_LIQUIDAR as DIAS4_180_0_, liquidacio0_.MES_DIAS as MES5_180_0_, liquidacio0_.MES_LIQUIDACION as MES6_180_0_, liquidacio0_.LIQUIDACION_TVAC as LIQUIDAC7_180_0_, liquidacio0_.FECHA_ESTADO as FECHA8_180_0_, liquidacio0_.fkSolicitud as fkSolici9_180_0_, liquidacio0_.idTvac as idTvac180_0_, liquidacio0_.NUMLIQ as NUMLIQ180_0_, liquidacio0_.legajo as legajo180_0_, liquidacio0_.periodo as periodo180_0_ from srh.srh_liquidacion liquidacio0_ where liquidacio0_.idLiquidacion=?]

这里发生异常：

sesionActiva.getTransaction().commit();

【参考方案1】：

尝试删除 catalog="srh"。这可能是问题所在：http://forums.mysql.com/read.php?39,137564,137629#msg-137629

【参考方案2】：

将架构名称更改为 PUBLIC 并且它工作（PUBLIC 应该是架构的名称）-;) ，所有其他架构名称都不起作用并给出“无效架构 ..name”错误。感谢我在这里找到的旧帖子 https://sourceforge.net/p/unitils/discussion/570578/thread/a887838e/
