Spring原始碼分析之元件掃瞄事件監聽處理器

判斷是否支援jpa來註冊持久化bean處理器

// check for jpa support, and if present add the persistenceannotationbeanpostprocessor.

if (jpapresent && !registry.containsbeandefinition(persistence_annotation_processor_bean_name)) 
catch (classnotfoundexception ex) 
def.setsource(source);
beandefs.add(registerpostprocessor(registry, def, persistence_annotation_processor_bean_name));
}if (!registry.containsbeandefinition(event_listener_processor_bean_name)) 
if (!registry.containsbeandefinition(event_listener_factory_bean_name))

if (!registry.containsbeandefinition(event_listener_processor_bean_name)) 

if (!registry.containsbeandefinition(event_listener_factory_bean_name))

catch (throwable ex)

} this.beanname = beanname;

this.method = method;

this.targetclass = targetclass;

this.bridgedmethod = bridgemethodresolver.findbridgedmethod(method);

eventlistener ann = annotatedelementutils.findmergedannotation(method, eventlistener.class);

this.declaredeventtypes = resolvedeclaredeventtypes(method, ann);

this.condition = (ann != null ? ann.condition() : null);

this.order = resolveorder(method);

this.methodkey = new annotatedelementkey(method, targetclass);}

初始化它的上下文屬性和事件表示式解析類，最後新增到上下文中

this.evaluator = evaluator;}

1.spring 執行原理 spring 啟動時讀取應用程式提供的 bean 配置資訊，並在 spring 容器中生成乙份相應的 bean 配置登錄檔，然後根據這張登錄檔例項化 bean，裝配好 bean 之間的依賴關係，為上 層應用提供準備就緒的執行環境。二 spring 原始碼分析 1.1spr...

一般情況下，我們spring採用反射來例項化物件，可是spring也提供了另一種方式，既通過實現factorybean來描述bean的例項化過程。public inte ce factorybean 介面描述很簡單 獲取bean，獲取bean的型別，是否是單例 public class carpub...
