spring boot +swagger+mssql +lombok+mybatis的List<Dto> 参数

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">
