我有一个 springboot 应用程序，我正在尝试使用 bytebuddy 来检测它。我遇到了我无法理解的类路径问题。
首先，以下是这方面的其他文献：

问题是 Spring-boot 将应用程序捆绑到一个 uber-jar 中，其中包含其他 jar
这里需要注意的是，如果我使用 IntelliJ 运行应用程序，它不会使用 uber-jar 并通过主类运行，并使用一堆 jar 作为类路径参数。
由于这种差异，当通过 uber-jar 运行时（java -jar target/demo-0.0.1-SNAPSHOT.jar），某些类在代理运行时不可用。这些类可以在应用程序 main 时加载，因为 spring-boot 使用自己的类加载器，该类加载器是在代理和应用程序 main 方法的某个时间创建的。
我将在下面描述不同时间点的行为：
代理 PreMain 时
Thread.currentThread().getContextClassLoader() = Launcher$AppClassLoaderAgent.class.classLoader = Launcher$AppClassLoaderClass.forName("org.springframework.web.servlet.HandlerAdapter") => ClassNotFoundExceptionClass.forName("javax.servlet.http.HttpServletRequest") => ClassNotFoundException
spring 和 javax 类都不会加载，因为它们并不按照应用程序类加载器直接位于类路径中。它是内罐的一部分，就像app.jar!/BOOT-INF/lib/some.jar应用程序类加载器将无法加载它。
在应用程序主课时
-
Thread.currentThread().getContextClassLoader() = org.springframework.boot.loader.LaunchedURLClassLoader
DemoApplication.class.classloader = same as aboveClass.forName("org.springframework.web.servlet.HandlerAdapter") => loads successfully- javax 类相同，加载成功。
加载后，Class.forName("javax.servlet.http.HttpServletRequest").classLoader也是一样LaunchedURLClassLoader.
在那个时间builder.visit调用（当bytebuddy修改类定义时）
Code:
我有两节课SpringBootInterceptor（其中包含拦截方法）和SpringBootInterceptorOne（其中包含进入和退出方法）
@Override
public AgentBuilder intercept(AgentBuilder agentBuilder) {
return agentBuilder
.type(isSubTypeOf(HandlerAdapter.class))
.transform((builder, typeDescription, classLoader, module) ->
builder.visit(Advice.to(SpringBootInterceptorOne.class, SpringBootInterceptorOne.class).on(named("handle").and(isMethod())))
);
}
功能intercept()在 premain 路径中被调用。
功能visit当实际尝试加载类型时调用。此时，bytebuddy 会尝试拦截这些方法并修改字节码。
在此代码的当前版本中，该函数intercept() throws ClassNotFoundException并且不会发生拦截。
Caused by: java.lang.NoClassDefFoundError: org/springframework/web/servlet/HandlerAdapter
因此，我尝试将代码更改为以下内容：
@Override
public AgentBuilder intercept(AgentBuilder agentBuilder) {
return agentBuilder
// .type(isSubTypeOf(HandlerAdapter.class))
.type(not(isInterface())
.and(safeHasSuperType(named("org.springframework.web.servlet.HandlerAdapter"))))
.transform((builder, typeDescription, classLoader, module) ->
builder.visit(Advice.to(SpringBootInterceptorOne.class, SpringBootInterceptorOne.class).on(named("handle").and(isMethod())))
);
}
在这里，基本上是延迟加载类。
datadog 的辅助函数：
https://github.com/DataDog/dd-trace-java/blob/master/dd-java-agent/agent-tooling/src/main/java/datadog/trace/agent/tooling/ByteBuddyElementMatchers.java https://github.com/DataDog/dd-trace-java/blob/master/dd-java-agent/agent-tooling/src/main/java/datadog/trace/agent/tooling/ByteBuddyElementMatchers.java
执行此操作后，intercept功能不会失败，但是visit()函数的行为很奇怪：

在此刻，
Thread.currentThread().getContextClassLoader() => LaunchedURLClassLoaderSpringBootInterceptor.class.getClassLoader() = null- Typing
SpringBootInterceptor.class在调试器窗口中不会失败，但是
-
Class.forName("my.package.name.SpringBootInterceptorOne")=> 未找到类定义
接下来，我尝试了以下操作：
@Override
public AgentBuilder intercept(AgentBuilder agentBuilder) {
ClassLoader cl = Thread.currentThread().getContextClassLoader();
return agentBuilder
// .type(isSubTypeOf(HandlerAdapter.class))
.type(not(isInterface())
.and(safeHasSuperType(named("org.springframework.web.servlet.HandlerAdapter"))))
.transform((builder, typeDescription, classLoader, module) -> {
try {
Class<?> claz = Thread.currentThread().getContextClassLoader().loadClass("my.package.name.SpringBootInterceptorOne");
return builder.visit(Advice.to(claz, claz,
new ClassFileLocator.Compound(ClassFileLocator.ForClassLoader.of(cl),
ClassFileLocator.ForClassLoader.of(Thread.currentThread().getContextClassLoader())
)).on(named("handle").and(isMethod())));
} catch (ClassNotFoundException e) {
e.printStackTrace();
return builder;
}
}
);
}
这会导致拦截器被“安装”。进入和退出方法都调用okay。但是将参数转换为正确的类型会给参数类型带来错误
exit spring boot

这里有SpringBootInterceptorOne供参考：
@Advice.OnMethodExit
static void exit(@Advice.Origin final Executable executable,
@Advice.This Object handlerAdapter,
@Advice.AllArguments Object[] arguments,
@Advice.Enter final TimerContext ctx) {
// final long duration = ctx.getDuration();
System.out.println("exit spring boot");
String e = getEndpoint(arguments);
System.out.println(e);
}
public static String getEndpoint(Object[] arguments) {
System.out.println(arguments);
HttpServletRequest request = (HttpServletRequest) arguments[0];
HandlerMethod handler = (HandlerMethod) arguments[2];
return "ad";
}
UPDATE:
根据答案中提供的建议，我尝试了以下操作：
@Override
public AgentBuilder intercept(AgentBuilder agentBuilder) {
return agentBuilder
// .type(isSubTypeOf(HandlerAdapter.class))
.type(not(isInterface())
.and(safeHasSuperType(named("org.springframework.web.servlet.HandlerAdapter"))))
.transform(new AgentBuilder.Transformer.ForAdvice()
.include(SpringBootInterceptorOne.class.getClassLoader())
.include(getClass().getClassLoader())
.advice(named("handle"), SpringBootInterceptorOne.class.getName())
);
}
它再次抛出错误：
