MyBatis like报错

错误的likeSQL语句是这么写的

select * from student name like '%#{name}%'

下面是错误信息

Parameter index out of range (1 > number of parameters, which is 0).

#{}编译后是一个占位符，下面是编译后的结果

elect * from student WHERE name like '%?%'

？存在于引号内，Mybatis找不到占位符报以上错误
正确写法
1、有可能会引起SQL注入

使用 ${...} 代替 #{...}

   SELECT * FROM tableName WHERE name LIKE '%${text}%';

2、

<select id="selectPersons" resultType="person" parameterType="person">
  <bind name="pattern" value="'%' + _parameter.username + '%'" />
  select id,sex,age,username,password
  from person
  where username LIKE #{pattern}
</select>

3、上层解决、参数带上%%

selectExample.setName("%光%");
