1. 如果传递的是对象
<update id="updatePerson" parameterType="person">
update person set pname=#{pname},address=#{address} where pid=#{pid}
</update>
2. 使用map传参
<select id="getByCondition" parameterType="java.util.Map" resultType="person">
select *from person where pname=#{name} and address=#{address}
</select>
3.根据方法中参数列表的索引值
<select id="getByCondition2" resultType="person">
select *from person where pname=#{0} and address=#{1}
</select>
4.给参数起别名
List<PersonBean> getByCondition3(@Param("name") String name, @Param("add") String add);
<select id="getByCondition3" resultType="person">
select *from person where pname=#{name} and address=#{add}
</select>
