一、contextloaderlistener上下文載入器的***
呼叫contextinitialized
contextclass是通過spring自帶的配置檔案獲取的。
3.啟用this.context
可載入context的父上下文
this.context.setid("/boxing_plan" )
setservletcontext
setconfiglocation( "classpath*:config/spring-*.xml")
4. postprocessbeanfactory(beanfactory);
beanfactory.registerscope
contextattributes,tempdir..web.xml
5.invokebeanfactorypostprocessors(beanfactory);{
beanfactory.getbeansoftype會去獲取如果存在會進行bean初始化
internalconfigurationannotationprocessor=configurationclasspostprocessor
configurationclasspostprocessor.postprocessbeandefinitionregistry(registry)
configurationclasspostprocessor.postprocessbeanfactory(beanfactory)
這裡可自定義屬於自己的beanfactorypostprocessor
6.registerbeanpostprocessors(beanfactory){
以下的bean也會被初始化
獲取beanpostprocessor.class
beanfactory.addbeanpostprocessor(newbeanpostprocessorchecker(beanfactory, beanprocessortargetcount));
處理 優先順序priorityordered 沒優先順序順序ordered 無序列
priorityordered
autowiredannotationbeanpostprocessor
instanceof mergedbeandefinitionpostprocessor-> internalpostprocessors.add
requiredannotationbeanpostprocessor internalpostprocessors.add
commonannotationbeanpostprocessor internalpostprocessors.add
configurationclasspostprocessor$importawarebeanpostprocessor
ordered
internalautoproxycreator
noneordered
ordercomparator.sort(priorityorderedpostprocessors)
beanfactory.addbeanpostprocessor
proxytargetclass
7. initmessagesource();{
可自定義messagesource
new delegatingmessagesource()
beanfactory.registersingleton(messagesource,delegatingmessagesource)
9. onrefresh();{
this.themesource =resourcebundlethemesource
10. registerlisteners();{
11. finishbeanfactoryinitialization(beanfactory);{
beanfactory.settempclassloader(null);
beanfactory.freezeconfiguration();//快取所有bean的物件，不能被改變
beanfactory.preinstantiatesingletons();確保所有bean都被例項化了{
//例項化所有非懶載入的單例bean
//區分工廠bean和普通bean
工廠bean有sqlmapclientfactorybean
12. finishrefresh();{
initlifecycleprocessor()->newdefaultlifecycleprocessor()
beanfactory.setlifecycleprocessor lifecycleprocessor.setbeanfacotry
lifecyclebeans暫時沒用到
new contextrefreshedevent(this)
ReentrantLock原始碼詳細解讀
reentrantlock是面試中的高頻考點，其中實現原理還是很有必要了解的。它與synchronized類似，都是互斥鎖，但具有更好的擴充套件性。reentrantlock是基於aqs實現的，遺忘的同學可以回顧一下aqs原始碼詳細解讀。1.1 繼承關係概述 首先看一下繼承關係圖，對它整體的構造有乙...
