1, before modification codes:
@Select("select * from fruitsell where f_id=#{f_id} and u_id=#{u_id}")
public Fruitsell finbyfruitsell(Long f_id,Long u_id);
修改后的代码:
@Select("select * from fruitsell where f_id=#{0} and u_id=#{1}")
public Fruitsell finbyfruitsell(Long f_id,Long u_id);
In this manner into 0,1,2,3 sequence matching.
2、
Error: $ {Name}
right: $ {name}
Since the EL read attribute getter methods, generally in accordance with the first letter in lowercase processing properties.
3、
@Select ( "SELECT * WHERE F_ID from fruitsell F_ID = {# #} and U_ID = {} U_ID")
public Fruitsell finbyfruitsell (@Param ( "F_ID") Long F_ID, the Param @ ( "F_ID") Long U_ID);
plus a @Param comment on it.
