## 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

  - ### 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
