今天在寫模糊分頁查詢的時候報錯如下：

mybatis配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.kj.rbacweb.dao.UserDao">
	<select id="pageQueryData" resultType="com.kj.rbaccommon.bean.User">
		select * from t_user 
		<where>
			<if test="queryText != null and queryText != ''">
				loginacct like concat('%','#{queryText}','%')
			</if>
		</where>
		limit #{start},#{size}
	</select>
	<select id="pageQueryCount" resultType="int">
		select count(*) from t_user
		<where>
			<if test="queryText != null and queryText != ''">
				loginacct like concat('%','#{queryText}','%')
			</if>
		</where>
	</select>
</mapper>
 

錯誤sql語句：

loginacct like concat('%','#{queryText}','%')

修改：去掉 ‘#{queryText}’ 中的’’ 正確

loginacct like concat('%',#{queryText},'%')
