解决方案：修改属性：jbpm.hibernate.cfg.xml org.hibernate.dialect.MySQLDialect

org.hibernate.dialect.MySQLInnoDBDialect 


InnoDB 给 MySQL 提供了具有事务(commit)、回滚(rollback)和崩溃修复能力(crash recovery capabilities)、多版本并发控制(multi-versioned concurrency control)的事务安全(transaction-safe (ACID compliant))型表。InnoDB 提供了行级锁(locking on row level)，提供与 Oracle 类似的不加锁读取(non-locking read in SELECTs)。InnoDB锁定在行级并且也在SELECT语句提供一个Oracle风格一致的非锁定读。另外InnoDB是为处理巨大数据量时的最大性能设计。它的CPU效率可能是任何其它基于磁盘的关系数据库引擎所不能匹敌的。MySQLInnoDBDialect基于上也就有InnoDB相同的功能.
