我有一个Spring Boot MVC Web应用程序表格。 用户可以在字段中键入和对象名称。此字段会获得一个已存在对象的自举式提前动态列表。
当用户在预先输入列表中选择一个已知对象时，我想用几个对象属性自动填充表单的杂项字段。
我的问题是，在springboot中正确实施MVC时，应该怎么做？如何告诉我的控制器“嘿，用户选择了-foo-对象，现在填写其他字段！” ？ 应该是表单的POST吗？ 可以在控制器中放入一种@heyFillTheForm吗？
谢谢

从设计的角度来看，我确实希望使用XHR来发布或放置表单的那些部分。
但是，我认为会创建两个单独的MVC控制器方法：
select
a.result_id, //product result id in table a, b
a.wc_code,
a.order_no_d, //product order # in table a = c
c.item_code,
d.item_name,
a.prod_date,
a.lot_no,
a.item_no,
a.plt_no,
a.grade,
b.rework_seq + 1, //this is only in rework_seq table
b.diposition_code,
b.defect_code, //defect codes are A through Z and each rework attempt has different defect code
b.defect_code2,
b.defect_code3,
a.insp_work_date as Inspection_Date, //getting inspection date from prod_result table because this will be final inspection date when reworked products get A grade.
a.insp_work_id as Inspector_ID
from
prod_result a,
rework_history b,
prod_order_detail c,
item d
where
a.result_id = b.result_id
and a.order_no = c.order_no
and c.item_code = d.item_code
and a.plant_code = 'T337'
and b.rework_seq = //this is the part.. I can't tell what max # rework_seq is
a.grade = 'A'
and a.result_id in (select result_id from rework_history) //This part sort out first pass A grade from A grade achieved through rework.
and b.enrl_date between to_date('2018-06-01 07:00:00', 'yyyy-mm-dd hh24:mi:ss') //enrl_date is reworked date and this date doesn't exist in prod_result table. So in order to get all rework date on all rework, this data should come from rework_history table.
and to_date('2018-07-01 07:00:00', 'yyyy-mm-dd hh24:mi:ss') " +
order by Inspection_Date asc;
的对象，返回带有预填充值的JSON对象。有人可能会说这应该是retrieveAutofillValues PUT的POST，返回提交结果
