原
spring boot +swagger+mssql +lombok+mybatis的List<Dto> 参数
分类:
Java
一、参数为list实体model时(注意list参数一定要用对应的类型接收传回的参数，不然会报错)
接口效果
注意list参数默认是必填，想不填必须在@RequestParam等接收参数里改
二、list参数在mapper.xml里面的写法
<?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">
<!--这个是接口路径集dao层-->
<mapper namespace="com.example.My10_18.mapper.IForms_UserInfoMapper">
<!-- 添加-->
<insert id="addF_User">
insert Forms_UserInfo values
<foreach collection="listInput" item="item" separator=",">
(#{item.forms_id},#{item.userinfo_id})
</foreach>
</insert>
<!--删除-->
<delete id="delF_User">
delete Forms_UserInfo
<where>
<if test="forms_ids!=null and forms_ids.size()>0">
and
<foreach collection="forms_ids" item="item" separator="or">forms_id=#{item}</foreach>

<if test="userinfo_ids!=null and userinfo_ids.size()>0">
and <foreach collection="userinfo_ids" item="item" separator="or">userinfo_id=#{item}</foreach>
</if>
