Activiti5.19查询报错[java.sql.SQLSyntaxErrorException: ORA-00936: 缺失表达式]

一.问题

今天用activiti新做一个项目,直接复制之前的代码,然后建数据库,随手把Spring,Spring MVC和Mybatis等版本升级了一下,问题就出现了.

所有activiti自带的查询都无法使用,全部报错如下

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.apache.ibatis.exceptions.PersistenceException: 
### Error querying database.  Cause: java.sql.SQLSyntaxErrorException: ORA-00936: 缺失表达式

### The error may exist in org/activiti/db/mapping/entity/Task.xml
### The error may involve org.activiti.engine.impl.persistence.entity.TaskEntity.selectTaskByQueryCriteria-Inline
### The error occurred while setting parameters

    org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:981)

简单查看SQL问题应该在order by后面没有字段,但是所有查询都是这个报错就不应该了,找了好久都没发现那里出了问题

二.解决

想了半天终于想起来了,之前的项目用的mybatis是3.2.6版本的,在这个项目里升级到3.3.0版本,问题可能出在这里
赶紧回滚到3.2.6版本,果然就解决了….真是坑爹
