java - mybatis查询不到数据,而直接执行SQL可以执行?

如题,结果如下:

程序查询的输出:

DEBUG queryCompany:145 - ==>  Preparing: SELECT b.id, b.name, b.average, COUNT(*) as times FROM (SELECT id, name, average from baseinfo WHERE id = ? or name LIKE ? ORDER BY average DESC LIMIT ?, ?) as b LEFT JOIN detailinfo AS d ON (b.id = d.id) GROUP BY b.id 
DEBUG queryCompany:145 - ==> Parameters: 江(String), %江%(String), 0(Integer), 6(Integer)
DEBUG queryCompany:145 - <==      Total: 0

然后我把这个sql语句直接放到数据库里查询,结果如下:

MariaDB [stock]> SELECT b.id, b.name, b.average, COUNT(*) as times FROM
    ->   (SELECT id, name, average
    ->    from baseinfo WHERE id = "江" or name LIKE "%江%"
    ->    ORDER BY average DESC LIMIT 0, 6) as b
    ->   LEFT JOIN detailinfo AS d ON (b.id = d.id)
    -> GROUP BY b.id;
+--------+--------------+------------+-------+
| id     | name         | average    | times |
+--------+--------------+------------+-------+
| 600418 | 江淮汽车     | 0.99999999 |     8 |
| 601313 | 江南嘉捷     | 0.16716038 |    10 |
+--------+--------------+------------+-------+
2 rows in set (0.00 sec)

之前都还能正常查询的,求问这是怎么回事


数据库挂掉了,还没恢复,所以没法测试是不是各位提的问题。。恢复后我会第一时间测试的

    Mybatis configuration problem, I guess it may be a problem with # and $, I don’t know if your configuration is written like this

    SELECT b.id, b.name, b.average, COUNT(*) as times FROM (SELECT id, name, average from baseinfo WHERE id = #{id} or name LIKE #{name} ORDER BY average DESC LIMIT #{}, #{}) as b LEFT JOIN detailinfo AS d ON (b.id = d.id) GROUP BY b.id

    Add ?autoReconnect=true&useUnicode=true&characterEncoding=utf8 after the connection database address

    It should be a configuration problem of mybatis. It almost appears near like. You can do it like this: like CONCAT('%',#{XXX},'%')

    你数据库层面是不是用了cobar或者TDDL   分库分表的中间件啊??

    I guess it’s also an encoding problem
