我正在尝试使用EclipseLink在Glassfish中使用JPA编辑Postgresql中的表.当我插入一个实体时,它运行正常.但是,当我尝试编辑或删除同一个实体时,它会因以下错误而失败.任何的想法？
Caused by: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.0.1.v20100213-r6600): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: org.postgresql.util.PSQLException: ERROR: operator does not exist: integer = character varying
Hint: No operator matches the given name and argument type(s). You might need to add explicit type casts.
