unexpected token异常

在开发中需要输入查询，遇到了下面的异常信息

我的java代码是：

Session session = getHibernateTemplate().getSessionFactory()
	.getCurrentSession();
StringBuffer queryString = new StringBuffer();
queryString.append("select    bmb.bombId,bmb.userid,bmb.bombType,bmb.bombState,bmb.bombRead," +
	"b.bomId,b.bomTopic,b.userid,b.bomRecList,b.bomCopyList,b.bomSecList,b.bomTime,b.bomState,bmb.bomfId,f.bomfName," +
	"bbu.userName,bbu.userAccount,bbu.empId,s.userName,s.userAccount" +" from BlOaMailBox as bmb left outer join bmb.bm as b left outer join bmb.bmf as f left outer join bmb.blBasicUser as bbu left outer join b.sender as s " +"where 1=1");

if (vo.getBomId() != null && !"".equals(vo.getBomId())) {
	queryString.append(" and bmb.bomId=:bomId");
}
if (vo.getUserid() != 0) {
	queryString.append(" and bmb.userid=:userid");
}
if (vo.getBombType() != null) {
	queryString.append(" and bmb.bombType=:bombType");
}
if (vo.getBomfId() != null&&vo.getBomfId() !=0) {
	queryString.append(" and bmb.bomfId=:bomfId");
}
if (vo.getBombState() != null) {
	queryString.append(" and bmb.bombState=:bombState");
}
if (vo.getBombRead() != null) {
	queryString.append(" and bmb.bombRead=:bombRead");
}
//按发送人查询
if(vo.getSendName()!=null&&!"".equals(vo.getSendName())){
	queryString.append(" and s.userAccount like "+"%"+vo.getSendName()+"%");
}
//按邮件发送时间排列
if(vo.getSortName()!=null&&vo.getSortName().equals("bomTime")&&vo.getSortorder()!=null&&!vo.getSortorder().equals("")){
	queryString.append(" order by b."+ vo.getSortName() +" "+ vo.getSortorder() );
}
//文件夹排列
if(vo.getSortName()!=null&&vo.getSortName().equals("folderName")&&vo.getSortorder()!=null&&!vo.getSortorder().equals("")){
	queryString.append(" order by f.bomfName "+ vo.getSortorder() );
}
//按是否已读状态排列
if(vo.getSortName()!=null&&vo.getSortName().equals("mailRead")&&vo.getSortorder()!=null&&!vo.getSortorder().equals("")){
	queryString.append(" order by bmb.bombRead "+ vo.getSortorder() );
}
//按发送人排列
if(vo.getSortName()!=null&&vo.getSortName().equals("senderName")&&vo.getSortorder()!=null&&!vo.getSortorder().equals("")){
	queryString.append(" order by s.userAccount "+ vo.getSortorder() );
}
//按邮件主题排列
if(vo.getSortName()!=null&&vo.getSortName().equals("bomTopic")&&vo.getSortorder()!=null&&!vo.getSortorder().equals("")){
	queryString.append(" order by b.bomTopic "+ vo.getSortorder() );
}
//按邮件类型排列
if(vo.getSortName()!=null&&vo.getSortName().equals("bomType")&&vo.getSortorder()!=null&&!vo.getSortorder().equals("")){
	queryString.append(" order by bmb.bombType "+ vo.getSortorder() );
}
Query q = session.createQuery(queryString.toString());
		
if (vo.getBomId() != null && !"".equals(vo.getBomId())) {
	q.setString("bomId", vo.getBomId());
}
if (vo.getUserid() != 0) {
	q.setLong("userid", vo.getUserid());
}
if (vo.getBombType() != null) {
	q.setInteger("bombType", vo.getBombType());
}
if (vo.getBomfId() != null&&vo.getBomfId() !=0) {
	q.setLong("bomfId", vo.getBomfId());
}
if (vo.getBombState() != null) {
	q.setInteger("bombState", vo.getBombState());
}
if (vo.getBombRead() != null) {
	q.setInteger("bombRead", vo.getBombRead());
}

导致错误的原因是28行，在这种情况下输入数字或英文可以通过，但是输入中文就报上面的错误。这可能是编码的问题，我却从另一个方面解决了这个问题：

将28行的代码也改成下面的形式

queryString.append(" and s.userAccount like :sendName");

并且在后面也加上这段代码

if(vo.getSendName()!=null&&!"".equals(vo.getSendName())){
	q.setString("sendName", "%"+vo.getSendName()+"%");
}

这样输入中文就可以通过了。
