mbatis中做LIKE模糊查询
今天在mbatis中做LIKE模糊查询，需要对一个name字段做模糊查询，发现用#{text}查询不到数据， 后来经过一系列搜索发现按照下面的方法可以进行查询
1.参数中直接加入%%
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>2.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>3.CONCAT
where username LIKE concat(concat('%',#{username}),'%')- Post Title: mbatis中做LIKE模糊查询
