當通過xml檔案載入所有的bean到ioc容器裡面後，可以通過getbean方法來獲取所需要的類的實類
public
public
static
void
main(string args)
}
public object getbean(string name) throws bean***ception
public
t getbean(string name, @nullable classrequiredtype) throws bean***ception
public object getbean(string name, object... args) throws bean***ception
public
t getbean(string name, @nullable classrequiredtype) throws bean***ception
public object getbean(string name, object... args) throws bean***ception
public
t getbean(string name, @nullable classrequiredtype, @nullable object... args) throws bean***ception
protected t dogetbean(string name, @nullable classrequiredtype, @nullable object args, boolean typecheckonly) throws bean***ception else
}bean = this.getobjectforbeaninstance(sharedinstance, name, beanname, (rootbeandefinition)null);
} else
beanfactory parentbeanfactory = this.getparentbeanfactory();
if (parentbeanfactory != null && !this.containsbeandefinition(beanname))
if (args != null)
return parentbeanfactory.getbean(nametolookup, requiredtype);
}if (!typecheckonly)
try
this.registerdependentbean(dep, beanname);
try catch (nosuchbeandefinitionexception var24) }}
if (mbd.issingleton()) catch (bean***ception var5)
});bean = this.getobjectforbeaninstance
(sharedinstance, name, beanname, mbd);
} else
if(mbd.isprototype()) finally
bean = this.getobjectforbeaninstance
(prototypeinstance, name, beanname, mbd);
} else
try finally
return var4;
});bean = this.getobjectforbeaninstance
(scopedinstance, name, beanname, mbd);
} catch
(illegalstateexception var23)
}} catch
(bean***ception var26) }if
(requiredtype != null && !requiredtype.isinstance(bean)) else
} catch
(typemismatchexception var25)
throw
newbeannotofrequiredtypeexception
(name, requiredtype, bean.getclass());
}} else
}
protected string transformedbeanname(string name)object sharedinstance = this.getsingleton(beanname);在方法裡面會判斷該bean實類的型別並返回,接下來會判斷是否存在，然後載入logger，
bean = this.getobjectforbeaninstance(sharedinstance, name, beanname, (rootbeandefinition)null);並且實類化

Spring裝配Bean的過程
spring裝配bean的過程 1.例項化 2.設定屬性值 3.如果實現了beannameaware介面,呼叫setbeanname設定bean的id或者name 4.如果實現beanfactoryaware介面,呼叫setbeanfactory 設定beanfactory 6.呼叫beanpost...
