Caused by: org.apache.ibatis.binding.BindingException: Parameter ‘xxx‘ not found. Available paramete

错误信息：绑定异常：参数“xxx” 没找到

提示：这里描述项目中遇到的问题：
例如：数据传输过程中数据不时出现丢失的情况，偶尔会丢失一部分数据
APP 中接收数据代码：

@Override
        public void run() {
            bytes = mmInStream.read(buffer);
            mHandler.obtainMessage(READ_DATA, bytes, -1, buffer).sendToTarget();
        }

找到对应的数据访问层（也叫Dao层），我这里是在TeacherDao.java里面：

public interface TeacherDao { 

	// 根据登录名和密码查询教师
	Teacher selectByLoginNameAndPassword(String loginName, String password);
	

错误信息说我“loginName”没找到，可能方法的参数没传进去。

简单改改：（加上@Param注解即可，org.apache.ibatis.annotations.Param 全类名）

import org.apache.ibatis.annotations.Param;

public interface TeacherDao { 

	// 根据登录名和密码查询教师
	Teacher selectByLoginNameAndPassword(@Param("loginName") String loginName, @Param("password")String password);
	
}
