Base API for building infrastructure using spring

First, get the object class name

Class<?> Handlerclass = classutils. Getuserclass (handler);

Second, query whether a method has an annotation

requestmapping mapping = annotationutils. findannotation requestmapping. class );

Iii. obtaining a class that implements an interface

Beanfactoryutils. beansoftypeincludingancestors (Context, handlermapping. class, true, false);

Iv. getting the class object corresponding to a string

Class<?> clazz = classutils. forname (ClassName, this. getclass (). getClassLoader ());  

v. creating managed beans using the Spring context

protected Object Createdefaultstrategy (applicationcontext context, class<?> clazz) {
return context.getautowirecapablebeanfactory (). Createbean (Clazz);
}

Get the Class property of an incoming object and find its registered object name in the Spring container accordingly beanname

Getapplicationcontext (). Getbeannamesfortype (Object. Class)

Querying all beanname registered in the Spring container According to the parent of the incoming object class

Beanfactoryutils. beannamesfortypeincludingancestors (Getapplicationcontext (), Object. class)

In the Spring container, find the corresponding annotation on this object according to Beanname , note that not all annotations

ApplicationContext context = Getapplicationcontext ();
requestmapping mapping = Context.findannotationonbean (Beanname, requestmapping. Class);

Spring uses beanname to find out the class type of this object

class<?> Handlertype = Context.gettype (beanname);

Method Methodtoinvoke = Bridgemethodresolver. Findbridgedmethod (Initbindermethod);

Reflectionutils. makeaccessible (Methodtoinvoke);

X. Getting an object with an annotation

String[] Beannames = (this. Detecthandlersinancestorcontexts ?
Beanfactoryutils. beannamesfortypeincludingancestors (Getapplicationcontext (), Object. class) :
Getapplicationcontext (). Getbeannamesfortype (Object. Class));//Get all beanname

for (String beanname:beannames) {

class<?> Handlertype = Context.gettype (beanname);

ApplicationContext context = Getapplicationcontext ();

if (Annotationutils. findannotation (Handlertype, Controller.) class) ! = null) {

}

}

Xi. Spring Collections static method

Collectionutils.mergearrayintocollection
