jbpm4.4 deleteProcessInstanceCascade: a foreign key constraint fails

参考: http://blog.csdn.net/zhouyong0/archive/2010/12/20/6086426.aspx

jBPM4.4 执行 executionService.deleteProcessInstanceCascade(processInstanceId)时报以下错误

将hibernate.dialect 由 org.hibernate.dialect.MySQLDialect 改为 org.hibernate.dialect.MySQL5InnoDBDialect 即可

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Cannot delete or update a parent row: a foreign key constraint fails (`demo`.`jbpm4_execution`, CONSTRAINT `FK_EXEC_INSTANCE` FOREIGN KEY (`INSTANCE_`) REFERENCES `jbpm4_execution` (`DBID_`))
