java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for %

namespace="接口的路径"

修改后:

<mapper <span style="color:#ff0000;">namespace="org.order.mapper.OrderDao"</span>><select id="getOrderById" resultType="Order">select * from tbl_order where id = #{id}</select></mapper>

暂时出现的问题,欢迎补充
