抽象业务mapper

1.抽象业务代码

package com.xingyunliushui.dao;import java.util.List;public interface BaseQueryMapper {    <T> List<T> selectAll(T record);    <T> T selectOne(T record);    <T> Integer countSelect(T record);}

　调用时会报org.apache.ibatis.binding.BindingException异常

如：

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.nsac.xingyunliushui.user.RoleMapper.selectAll
    at org.apache.ibatis.binding.MapperMethod$SqlCommand.<init>(MapperMethod.java:225)
    at org.apache.ibatis.binding.MapperMethod.<init>(MapperMethod.java:48)
    at org.apache.ibatis.binding.MapperProxy.cachedMapperMethod(MapperProxy.java:65)
    at org.apache.ibatis.binding.MapperProxy.invoke(MapperProxy.java:58)
    at com.sun.proxy.$Proxy225.selectAll(Unknown Source)

    at java.lang.reflect.Method.invoke(Method.java:498)
    at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:333)

解决办法：还是要写mapper对应的xml文件。
