mybatis example 使用AND 和OR 联合查询

ViewPsmsgconsultExample example=new ViewPsmsgconsultExample();
ViewPsmsgconsultExample.Criteria criteria=example.createCriteria();
criteria.andToidEqualTo(mctid);
criteria.andStatusEqualTo("0");  

ViewPsmsgconsultExample.Criteria criteria2=example.createCriteria();
criteria2.andToidEqualTo(mctid);
criteria2.andLaststatusEqualTo("0");
example.or(criteria2);
psmsgconsultDao.countByExample(example);  

生成代码如下：

select count(*) from VIEW_PSMSGCONSULT WHERE ( TOID = ? and STATUS = ? ) or( TOID = ? and LASTSTATUS = ? )
