mybatis like模糊查询问题
- 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
CONCAT
where username LIKE concat(concat(‘%’,#{username}),’%’)
还没有评论,来说两句吧...
