- org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver

所有已实现的接口:
LoadTimeWeaver
```
public class InstrumentationLoadTimeWeaver
extends Object
implements LoadTimeWeaver
```
LoadTimeWeaver relying on VM Instrumentation.
Start the JVM specifying the Java agent to be used — for example, as follows where spring-instrument-{version}.jar is a JAR file containing the InstrumentationSavingAgent class shipped with Spring and where {version} is the release version of the Spring Framework (e.g., 5.1.5.RELEASE).
-javaagent:path/to/spring-instrument-{version}.jar
In Eclipse, for example, add something similar to the following to the JVM arguments for the Eclipse "Run configuration":
-javaagent:${project_loc}/lib/spring-instrument-{version}.jar
从以下版本开始:
2.0

构造器	说明
`InstrumentationLoadTimeWeaver()`	Create a new InstrumentationLoadTimeWeaver for the default ClassLoader.
`InstrumentationLoadTimeWeaver(ClassLoader classLoader)`	Create a new InstrumentationLoadTimeWeaver for the given ClassLoader.

所有方法静态方法实例方法具体方法
修饰符和类型	方法	说明
`void`	`addTransformer(ClassFileTransformer transformer)`	Add a `ClassFileTransformer` to be applied by this `LoadTimeWeaver`.
`ClassLoader`	`getInstrumentableClassLoader()`	We have the ability to weave the current class loader when starting the JVM in this way, so the instrumentable class loader will always be the current loader.
`ClassLoader`	`getThrowawayClassLoader()`	This implementation always returns a `SimpleThrowawayClassLoader`.
`static boolean`	`isInstrumentationAvailable()`	Check whether an Instrumentation instance is available for the current VM.
`void`	`removeTransformers()`	Remove all registered transformers, in inverse order of registration.

  - InstrumentationLoadTimeWeaver
```
public InstrumentationLoadTimeWeaver()
```
    Create a new InstrumentationLoadTimeWeaver for the default ClassLoader.
  - InstrumentationLoadTimeWeaver
```
public InstrumentationLoadTimeWeaver(@Nullable
                                     ClassLoader classLoader)
```
    Create a new InstrumentationLoadTimeWeaver for the given ClassLoader.
    参数:
    classLoader - the ClassLoader that registered transformers are supposed to apply to
- 方法详细资料
  - 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()
```
    We have the ability to weave the current class loader when starting the JVM in this way, so the instrumentable class loader will always be the current loader.
    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()
```
    This implementation always returns a SimpleThrowawayClassLoader.
    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
  - removeTransformers
```
public void removeTransformers()
```
    Remove all registered transformers, in inverse order of registration.
  - isInstrumentationAvailable
```
public static boolean isInstrumentationAvailable()
```
    Check whether an Instrumentation instance is available for the current VM.
