1.springfox-swagger实体类无限递归
https://hacpai.com/article/1525674135818 里面有不完美的解决方案
不用动源码的解决方案也有，在swagger项目里的函数传入参数没有类互相包含就可以了
这也要求某些多对多关系的实体类的属性定义要仔细走关系图
比如User和SysClass，用在swagger传入参数的实体类不能互相包含List<SysClass>和List<User>
只能继承VO（这个VO不能作为swagger函数的传入参数），把对应的包含属性写进去，然后需要查询对应列表时返回VO就行了
2.有中间表的mybatis一对多查询
查看某些有明确一对多关系的实体类的mybatis xml，可以看到查询方式是主表join子表，然后在mybatis这端把主表的数据group起来作为某个对象的元素
由此可见没有直接关联的2个表对应的类也可以用这种方式查询

3.swagger传入参数含有对象数组时的坑点
swagger前端在碰到对象数组（无论是直接传的还是实体类里面的）时，会显示xxx[0].id和xxx[0].name之类的参数，但是直接通过前端发送请求，会因为url含有非法字符被拒绝请求
如果是用其他程序提交，例如Python(先安装requests扩展包)，可以提交这种带对象数组的请求，并让服务器接收
import requests
import json def login():
res = requests.post('http://localhost:20005/api/user/login?userAccount=admin&userPassword=admin', verify=False)
myj = json.loads(res.text)
#print(myj)
return myj['data']['token']
#
def addContent():
token = login()
params = {
'resourceSteps[0].procedureName': 'ytmym',
'resourceSteps[0].procedureContent': 'mytm',
'resourceSteps[2].procedureName': 'loveZJJ',
'resourceSteps[2].procedureContent': 'asswecan',
'id': '',
'resourceContentId': '45j45j',
'experimentAdd': '5j5j',
'experimentAdd1': 'grh',
'stepsjson': '[{"procedureName":"a","procedureContent":"b"}]',
'token': token,
'resourceManagementId': 'j54j45j',
'experimentalObjective': '45j45j4',
'experimentalContext': '45j45j',
'experimentalRequirements': '5j45j',
'prepareKnowledge': '54j45j',
'experimentSummary': 'j54j',
'experimentTestId': 'h4h54'
}
url = 'http://localhost:20005/api/resource/add/content'
res = requests.post(url, params=params)
print(res.text)
#
if __name__ == '__main__':
addContent()
但是这种实现方式不太推荐，太不直观了。建议使用@ResponseBody注解对象数组或包含此类型的实体类，然后让前端传入json，处理会简单一些
