MyBatis模糊查询like的三种方式

public void select1(String name) {
     String name = "%" + name+ "%";
     userDao.select1(name);
 }

// Dao层指定参数别名
List<User> select1(@Param("name") String name);

<select id="select1" parameterType="string" resultType="com.why.mybatis.entity.User">
       SELECT
            *
        FROM
            t_user
        WHERE
            name LIKE #{name}
    </select>

name LIKE CONCAT('%',#{name},'%')
 name like "%"#{name}"%"
 <!--不建议可能会产生sql注入-->
 name like "%"${name}"%"

<select id="selectBykeyWord" parameterType="string" resultType="com.why.mybatis.entity.RoleEntity">
        <bind name="pattern" value="'%' + name + '%'" />
        SELECT
        *
        FROM
        t_role
        WHERE
        name LIKE #{pattern}
        OR
        id LIKE #{pattern}
    </select>
