类 DefaultContextLoadTimeWeaver

java.lang.Object

org.springframework.context.weaving.DefaultContextLoadTimeWeaver

所有已实现的接口:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanClassLoaderAware, org.springframework.beans.factory.DisposableBean, LoadTimeWeaver

public class DefaultContextLoadTimeWeaver
extends Object
implements LoadTimeWeaver, org.springframework.beans.factory.BeanClassLoaderAware, org.springframework.beans.factory.DisposableBean

Default LoadTimeWeaver bean for use in an application context, decorating an automatically detected internal LoadTimeWeaver.

Typically registered for the default bean name "loadTimeWeaver"; the most convenient way to achieve this is Spring's <context:load-time-weaver> XML tag.

This class implements a runtime environment check for obtaining the appropriate weaver implementation: As of Spring Framework 5.0, it detects Oracle WebLogic 10+, GlassFish 4+, Tomcat 8+, WildFly 8+, IBM WebSphere 8.5+, Spring's VM agent, and any ClassLoader supported by Spring's ReflectiveLoadTimeWeaver (such as Liberty's).

从以下版本开始:

2.5

DefaultContextLoadTimeWeaver

public DefaultContextLoadTimeWeaver(ClassLoader beanClassLoader)

方法详细资料

setBeanClassLoader

public void setBeanClassLoader(ClassLoader classLoader)

指定者:

setBeanClassLoader 在接口中 org.springframework.beans.factory.BeanClassLoaderAware

createServerSpecificLoadTimeWeaver

@Nullable
protected LoadTimeWeaver createServerSpecificLoadTimeWeaver(ClassLoader classLoader)

destroy

public void destroy()

指定者:

destroy 在接口中 org.springframework.beans.factory.DisposableBean

addTransformer

public void addTransformer(ClassFileTransformer transformer)

从接口复制的说明: LoadTimeWeaver

Add a ClassFileTransformer to be applied by this LoadTimeWeaver.

指定者:

addTransformer 在接口中 LoadTimeWeaver

参数:

transformer - the ClassFileTransformer to add

getInstrumentableClassLoader

public ClassLoader getInstrumentableClassLoader()

从接口复制的说明: LoadTimeWeaver

Return a ClassLoader that supports instrumentation through AspectJ-style load-time weaving based on user-defined ClassFileTransformers.

May be the current ClassLoader, or a ClassLoader created by this LoadTimeWeaver instance.

指定者:

getInstrumentableClassLoader 在接口中 LoadTimeWeaver

返回:

the ClassLoader which will expose instrumented classes according to the registered transformers

getThrowawayClassLoader

public ClassLoader getThrowawayClassLoader()

从接口复制的说明: LoadTimeWeaver

Return a throwaway ClassLoader, enabling classes to be loaded and inspected without affecting the parent ClassLoader.

Should not return the same instance of the ClassLoader returned from an invocation of LoadTimeWeaver.getInstrumentableClassLoader().

指定者:

getThrowawayClassLoader 在接口中 LoadTimeWeaver

返回:

a temporary throwaway ClassLoader; should return a new instance for each call, with no existing state
