mybatis做like模糊查询

这个网站中有很多方法点我跳转

自己试验了如下的方法。

参数中直接加入%%

      param.setUsername("%CD%");      param.setPassword("%11%");    <select  id="selectPersons" resultType="person" parameterType="person">        select id,sex,age,username,password from person where true             <if test="username!=null"> AND username LIKE #{username}</if>            <if test="password!=null">AND password LIKE #{password}</if>    </select>

---

bind标签

<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>

CONCAT

where username LIKE concat(concat('%',#{username}),'%')
