I have a domain model that corresponds to multiple tables when I use a relational database to design a data store. Now when I create this domain entity, I want to use Spring Data Jpa to write to multiple data tables at once. How to do it?
1.Domain Model:
{
"id": 2,
"startTime": "2018-07-09T08:59:08.853Z",
"endTime": "2018-07-09T08:59:08.853Z",
"group": 2,
"entries": [
{
"id": 1,
"target": 90,
"isFinished": false,
"name": "俯卧撑",
"groups": [
{
"id": 1,
"name": "第一组",
"number": 30
},
{
"id": 2,
"name": "第一组",
"number": 30
}
]
}
]
}
2.Data tables:
tb_execise_plan(id, start_time, end_time, group)
tb_execise_entry(id,name,target, is_finished, execise_plan_id, project_id)
tb_execise_entry_group(id,name,number,execise_entry_id)
3.Table relationship:
tb_execise_plan 1:m tb_execise_entry
tb_execise_entry 1:m tb_execise_entry_group
