MyBatis中SQL语句问题

在使用MyBatis的项目中，SQL语句如下就无法正常发布到Tomcat7.0

 <select id="queryEntrustUnit" resultType="String">

  select distinct entrustUnit from baseTable where (not entrustUnit is null) and entrustUnit<>'' Order by entrustUnit

 </select>

在下面的位置就卡住不动了：

把SQL修改成如下就没有问题了：

 <select id="queryEntrustUnit" resultType="String">

  select distinct entrustUnit from baseTable Order by entrustUnit

 </select>

终于知道原因了，<>要使用转义字符

MyBatis SQL xml处理小于号与大于号
