还有另一种了解依赖项的方法：
如果可以通过mvnrepository找到某些内容（例如Spring WebMVC），则可以在其中查找依赖项。
例如：
org.springframework » spring-webmvc
在以下位置：提供的依赖项
-------------------------------------------------------------- |WebMVC |Dependency |Min-Max version -------------------------------------------------------------- |5.1.9 |javax.servlet » javax.servlet-api|4.0.1 -------------------------------------------------------------- |5.0.15 |javax.servlet » javax.servlet-api|4.0.1 -------------------------------------------------------------- |4.3.25 |javax.servlet » javax.servlet-api|3.0.1 - 4.0.1 -------------------------------------------------------------- |4.2.9 |javax.servlet » javax.servlet-api|3.0.1 - 4.0.1 -------------------------------------------------------------- |4.1.9 |javax.servlet » javax.servlet-api|3.0.1 - 4.0.1 -------------------------------------------------------------- |4.0.9 |javax.servlet » javax.servlet-api|3.0.1 - 4.0.1 -------------------------------------------------------------- |3.2.18 |javax.servlet » javax.servlet-api|3.0.1 - 4.0.1 -------------------------------------------------------------- |3.1.4 |javax.servlet » javax.servlet-api|2.1 - 2.3.3 -------------------------------------------------------------- |3.0.7 |javax.servlet » javax.servlet-api|2.1 - 2.3.3 -------------------------------------------------------------- |2.5.6.SEC03|javax.servlet » javax.servlet-api|2.4 - 4.0.1 -------------------------------------------------------------- |2.0.8 |javax.servlet » javax.servlet-api|2.4 - 4.0.1 --------------------------------------------------------------

其依赖范围：“提供” @PowerStat，不应视为完全依赖。
def create(response):
if response.method == "POST":
form = CreateNewTrade(response.POST)
# Because form.is_valid() failed, t will be undefined
if form.is_valid():
n = form.cleaned_data["name"]
# Here only, you have assigned value of t
t = AssetList(name=n)
t.save()
response.user.assetlist.add(t)
return HttpResponseRedirect("/userdash/%i" %t.id)
# When if statements doesnot apply, always come to this line unless it goes inside form.is_valid()
return HttpResponseRedirect("/userdash/") # redirect to the page whose arguments doesnot depend upon the form subbmission
