    我这里打开没问题，你再试试。里面的内容大致

    我今天晚上也遇到这个问题，是在个人信息修改时出错的，看了很多这样子的解答，但是还是不行。但是后来我解决了原来我获取不到角色ID，用户的信息修改时就报错。我就在角色的dao层里面写个根据角色名称来获取角色列表的方法，即roleService.findByRname(rname)，这样角色ID就可以像下面这样获取到了。
    int rid = roleService.findByRname(rname).get(0).getRid();
    然后再把该ID用set给role   
     即role.setRid(rid);
    运行，就OK了
