/**尝试方法2 已解决： 关联对象传参问题**/
别用实体类传参，使用map。
Map map = new HashMap();
map.put("ttys",ttys);
map.put("phone",phone);
map.put("key_dm",key_dm);
map.put("password",password);
xml中的update语句修改成:
UPDATE dt_member_permission AS t1
LEFT JOIN dt_member AS t2 ON t1.member_id=t2.id
t1.key_dm=#{key_dm}
WHERE t1.ttys=#{ttys}
AND t2.phone=#{phone}
AND t2.password=#{password}
