PlaceholderConfigurerSupport类
spring提供的一个工具类,用于解析bean定义中属性值里面的占位符,此类不能被直接实例化使用
public abstract class PlaceholderConfigurerSupport extends PropertyResourceConfigurer
implements BeanNameAware, BeanFactoryAware
会把 > <context:property-placeholder location=“classpath:dbconfig.properties”></context:property-placeholder>
这个标签解析替换${jdbc.username}这样的内容
aop标签解析
<aop:config>

<aop:advisor advice-ref="myAdvice" pointcut-ref="txPoint"></aop:advisor>

根据标签名找到对应的handler
http\://www.springframework.org/schema/aop=org.springframework.aop.config.AopNamespaceHandler
AOP命名空间解析类。我们在用AOP的时候,会在Spring配置文件的beans标签中引入:xmlns:aop
public class AopNamespaceHandler extends NamespaceHandlerSupport {
@Override
public void init() {
// In 2.0 XSD as well as in 2.5+ XSDs
registerBeanDefinitionParser("config", new ConfigBeanDefinitionParser());
registerBeanDefinitionParser("aspectj-autoproxy", new AspectJAutoProxyBeanDefinitionParser());
registerBeanDefinitionDecorator("scoped-proxy", new ScopedProxyBeanDefinitionDecorator());
// Only in 2.0 XSD: moved to context namespace in 2.5+
registerBeanDefinitionParser("spring-configured", new SpringConfiguredBeanDefinitionParser());
}
}
/**解析自定义元素(在默认名称空间之外)。
* @param containingBd the containing bean definition (if any) @param containingBd包含bean的定义(如果有的话)
* @return the resulting bean definition 得到的bean定义
*/
@Nullable
public BeanDefinition parseCustomElement(Element ele, @Nullable BeanDefinition containingBd) {
// 获取对应的命名空间
String namespaceUri = getNamespaceURI(ele);
if (namespaceUri == null) {

// 根据命名空间找到对应的NamespaceHandlerspring
NamespaceHandler handler = this.readerContext.getNamespaceHandlerResolver().resolve(namespaceUri);
if (handler == null) {
error("Unable to locate Spring NamespaceHandler for XML schema namespace [" + namespaceUri + "]", ele);
return null;
}
// 调用自定义的NamespaceHandler进行解析 NamespaceHandlerSupport
return handler.parse(ele, new ParserContext(this.readerContext, this, containingBd));
}
handler.parse调用的是NamespaceHandlerSupport的parse方法,因为AopNamespaceHandler extends NamespaceHandlerSupport
/**

*/
@Override
@Nullable
public BeanDefinition parse(Element element, ParserContext parserContext) {
// 获取元素的解析器
BeanDefinitionParser parser = findParserForElement(element, parserContext);
return (parser != null ? parser.parse(element, parserContext) : null);//ComponentScanBeanDefinitionParser的方法

parser是ConfigBeanDefinitionParser:

parserContext.pushContainingComponent(compositeDef);
// 注册自动代理模式创建器,AspectjAwareAdvisorAutoProxyCreator 配置文件注解混合使用 context:commponentScan 注入innteral的类 这里也注入类似的类

parseAspect(elt, parserContext);
}
}
parserContext.popAndRegisterContainingComponent();
return null;
}
configureAutoProxyCreator(parserContext, element);的功能是AspectJAwareAdvisorAutoProxyCreator引入。
pointcut 和 advisor 标签会在parsePointcut(elt, parserContext);和parseAdvisor(elt, parserContext);方法解析生成bean对象。
**parsePointcut(elt, parserContext);**最终createPointcutDefinition:

return beanDefinition;
}
<aop:pointcut id="txPoint" expression="execution(* com.study.spring.tx.xml.*.*.*(..))"/>对应AspectJExpressionPointcut
**parseAdvisor(elt, parserContext);**最终调用createAdvisorBeanDefinition:

parseInternal(element, parserContext);是AbstractSingleBeanDefinitionParser的parseInternal方法

TransactionInterceptor

// 调用子类重写的doParse方法进行解析
doParse(element, parserContext, builder);
TxAdviceBeanDefinitionParser的doParse方法:
@Override

TxAdviceBeanDefinitionParser的parseAttributeSource方法:

ManagedMap<TypedStringValue, RuleBasedTransactionAttribute> transactionAttributeMap =

return attributeSourceDefinition;
}
<tx:attributes>
<tx:method name="checkout" propagation="REQUIRED" />
<tx:method name="updateStock" propagation="REQUIRES_NEW" />
</tx:attributes>
上述方法解析这些事务相关的标签,隔离级别、传播特性、超时时间、是否可读。这几个属性如果标签有设置就取没设置就用默认值。
方法最终返回了一个RootBeanDefinition,class是NameMatchTransactionAttributeSource.class
这一步完成,tx.xml文件的标签就解析完成,此时生成事务相关的如下:
此时befactory中bean定义信息如下:
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
<property name="username" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
<property name="url" value="${jdbc.url}"></property>
<property name="driverClassName" value="${jdbc.driverClassName}"></property>
</bean>
上面的属性值还是${jdbc.username}变量接下来要进行替换,在invokeBeanFactoryPostProcessors(beanFactory);方法中执行。调用PropertySourcesPlaceholderConfigurer类的方法
invokeBeanFactoryPostProcessors执行结束之后:
registerBeanPostProcessors方法执行结束之后:
AspectJAwareAdvisorAutoProxyCreator对象生成在一级缓存:
因为class AspectJAwareAdvisorAutoProxyCreator extends AbstractAdvisorAutoProxyCreator
public abstract class AbstractAdvisorAutoProxyCreator extends AbstractAutoProxyCreator
public abstract class AbstractAutoProxyCreator extends ProxyProcessorSupport
implements SmartInstantiationAwareBeanPostProcessor, BeanFactoryAware
interface SmartInstantiationAwareBeanPostProcessor extends InstantiationAwareBeanPostProcessor
interface InstantiationAwareBeanPostProcessor extends BeanPostProcessor
对象的创建有如下几种方式:
接下来开始讲解存储在bean定义信息map里的十个对象的循环创建过程:以dataSource为例,
