<select id="findassigneduserprivilege"
    resultMap="usermoduleprivilege">
    select

由此可看出,在ibatis的resultMap的result中使用“select”是一种迭代查询,也就是例子中 <result property="modulePrivilege"
column="{userId=userid, projectId=projectid}"
select="findassignedusermoduleprivilege" />  将column指定的一项或多项作为参数(userId=userid, projectId=projectid),传入并执行指定的select语句(findassignedusermoduleprivilege),并将查询结果赋给property="modulePrivilege"
