MyBatis注解select in參數

/**
 * 
 * @param ids '1,2,3'
 * @return
 */

@Select("select * from user_info where id in (${ids})")

List<UserInfo> getUserbyIds(@Param("ids")String ids);

 

參數需要使用${}來引用，#{}不能識別。【這個方案貌似不起作用】

            StringBuilder sql = new StringBuilder();

            sql.append("SELECT * FROM blog WHERE id in (");
            for (String id : idList)

                    sql.append(",");

                sql.append("'").append(id).append("'");
            }
            sql.append(")");

            return sql.toString();
        }

        public interface TestMapper
        {
            @SelectProvider(type = Test.class, method = "getTestQuery")
List<Blog> selectBlogs(@Param("idList") int[] ids);
        }
    }
