Spring prototype following prototype design pattern -

-

After "div class =" text "itemprop =" text ">

Spring provides a" prototype "as the scope of the scope. This means that whenever the bean is required in the application, the spring container will make a fresh / new example of bean. Is prototype design pattern also followed? Does it make the object in the request only once and at the time the call clone () method on the object created to create the new object?

Anyone can provide examples of prototype in JDK, Spring, Hibernate or any other J2EE framework, if additionally.

Below is the code snippet taken from AbstractBeanFactory.doGetBean () function: 

  // create sample examples. If (mbd.isSingleton ()) {sharedInstance = getSingleton (beanName, New ObjectFactory & lt; Object & gt; () {@Override Public Object GetObject () throws BeansException {try {return createBean (beanName, MBD, args);} Grab (BeansException East) {Clearly remove example from singleton cache //: It may have been put there // Excessively by the manufacturing process, to allow for circular reference solutions // Also there is any bean that Gets a temporary reference to beans destroySingleton (beanName ..; east ;;}}} Sam = getObjectForBeanInstance (shared person, name, name, MBD);} Else if (mbd.isprototype ()) {// This is a prototype -> Create a new instance object prototype = Instance = null Try; Prototype = Extension Bean (Biennam, MBD, Args);} After {Prototype Creation};} Sam = getObjectForBeanInstance (Prototype Instance, Name, Beename, MBD) Before Prototype Creation; ;}

createBean method call fold down below D: 

  BeanUtils.instantiateClass (constructorToUse);
