在mybatis通過名字查詢數量<select id="findUserCountByBack1" resultType="int" parameterType="User" > ????select count(*) from onlinemall_user where username like #{username} and userstatus=1; </select>在controller層user.setUsername("%"+username+"%");username已經注入進去，通過查詢user.getUsername（）能查到name但是int total=userBiz.findUserCount1(user);查詢出的total一直是0；dubug提示為:DEBUG [main] - ==> ?Preparing: select count(*) from onlinemall_user where username like ? and userstatus=1;?DEBUG [main] - ==> Parameters: nullTRACE [main] - <== ? ?Columns: count(*)TRACE [main] - <== ? ? ? ?Row: 0DEBUG [main] - <== ? ? ?Total: 10username沒成功注入進去，不知道哪兒原因，求解決!
