无法为AspectJ添加javaagent [英] Can't add javaagent for AspectJ
问题描述
我有一个旧的Java6应用程序，我试图添加一些自动和全局日志来跟踪每个方法中的每个调用.它运行在JBoss 4.2.3上.
I have an old Java6 Application, and I'm trying to add some automatic and global log for tracing every call in every method. It runs on a JBoss 4.2.3.
我有我的简介课:
package com.al6.borneIntranet.business.log;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.util.StopWatch;
import org.springframework.core.annotation.Order;
@Aspect
public class ProfilingAspect {
@Around("methodsToBeProfiled()")
public Object profile(ProceedingJoinPoint pjp) throws Throwable {
StopWatch sw = new StopWatch(getClass().getSimpleName());
try {
sw.start(pjp.getSignature().getName());
return pjp.proceed();
} finally {
sw.stop();
System.out.println(sw.prettyPrint());
}
}
@Pointcut("execution(public * com.al6.borneIntranet..*.*(..))")
public void methodsToBeProfiled(){}
}
我创建一个META-INF/aop.xml文件:
I create a META-INF/aop.xml file :
<!DOCTYPE aspectj PUBLIC "-//AspectJ//DTD//EN" "https://www.eclipse.org/aspectj/dtd/aspectj.dtd">
<aspectj>
<weaver>
<!-- only weave classes in our application-specific packages -->
<include within="com.al6.*"/>
</weaver>
<aspects>
<!-- weave in just this aspect -->
<aspect name="com.al6.borneIntranet.business.log.ProfilingAspect"/>
</aspects>
</aspectj>
我将这一行添加到我的bean定义xml中:
I add this line in my bean definitions xml :
<context:load-time-weaver/>
我有这个依赖项:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>

几乎可以使用，但是使用该应用程序时在启动时出现此错误:
It almost works, but I have this error at startup when I use the application :
2021-04-29 18:41:46,960 ERROR [STDERR] org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.context.weaving.AspectJWeavingEnabler#0': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loadTimeWeaver': Initialization of bean failed; nested exception is java.lang.IllegalStateException: ClassLoader [org.jboss.mx.loading.UnifiedClassLoader3] does NOT provide an 'addTransformer(ClassFileTransformer)' method. Specify a custom LoadTimeWeaver or start your Java virtual machine with Spring's agent: -javaagent:org.springframework.instrument.jar
我从maven存储库下载spring-instrument-4.0.6.RELEASE.jar文件，然后在运行启动脚本中添加javaagent部分:
I download the spring-instrument-4.0.6.RELEASE.jar file from maven repository, then I add the javaagent part in the run startup script :
/opt/jdk/bin/java -Dprogram.name=run.sh -javaagent:/opt/jboss/lib/org.springframework.instrument.jar -server -Xms2048m -Xmx2048m -XX:MaxPermSize=256M ...
但是错误仍然出现，就像我什么都不做.
But the error still appear, like I'm doing nothing.
有没有一种方法可以在启动时不轻易添加此选项?为什么甚至当我添加它时也没有使用它?
Is there a way to not add this option at startup easily ? Why even when I add it it is not used ?
我尝试添加adspectj启动代理，也无法正常工作，同样的错误，看来该应用程序未检测到该选项:
I try to add the adspectj launch agent, didn't work either, same error, it looks like the option is not detected by the application :

尝试几件事:
-
使用Jboss timeweaver:
Using Jboss timeweaver :
创建名称为"loadTimeWeaver"的Bean时出错:实例化Bean失败；嵌套的异常是org.springframework.beans.BeanInstantiationException:无法实例化bean类[org.springframework.instrument.classloading.jboss.JBossLoadTimeWeaver]:构造方法抛出了异常.嵌套的异常是java.lang.IllegalStateException:无法初始化JBoss LoadTimeWeaver，因为JBoss 6 API类不可用
Error creating bean with name 'loadTimeWeaver': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.instrument.classloading.jboss.JBossLoadTimeWeaver]: Constructor threw exception; nested exception is java.lang.IllegalStateException: Could not initialize JBoss LoadTimeWeaver because the JBoss 6 API classes are not available
当然，我正在使用Jboss 4.3.2
Of course, I'm on Jboss 4.3.2
- 添加"-verbose -showWeaveInfo -debug"在aop.xml中:
检测到该文件，因为我在启动时有以下几行:
The file is detected because I have this lines at startup :

我放的时候:
When I put :
<context:load-time-weaver weaver-class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/>
我有一个略有不同的错误，但结果相同:
I have a slightly different error, but same result :
2021-05-03 15:15:03,475 ERROR [STDERR] java.lang.IllegalStateException: Must start with Java agent to use InstrumentationLoadTimeWeaver. See Spring documentation. 2021-05-03 15:15:03,476 ERROR [STDERR] at org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver.addTransformer(InstrumentationLoadTimeWeaver.java:88)但是我已经添加了它:

找不到加载时编织为什么不起作用的原因.
Can't find why load-time weaving don't work.
所以，在我工作的人只是问我为什么要进行加载时编织，为什么不只是进行编译时编织".
So, somebody at my work just ask me why I want to do loadtime weaving, why don't just do "compile time weaving".
我只是将其添加到我的pom.xml中:
I just add this in my pom.xml :
<plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>aspectj-maven-plugin</artifactId> <version>1.7</version> <configuration> <complianceLevel>1.6</complianceLevel> <source>1.6</source> <target>1.6</target> <showWeaveInfo>true</showWeaveInfo> <verbose>true</verbose> <Xlint>ignore</Xlint> <encoding>UTF-8 </encoding> </configuration> <executions> <execution> <goals> <!-- use this goal to weave all your main classes --> <goal>compile</goal> </goals> </execution> </executions> </plugin>我删除了javaagent的东西.
I delete javaagent things.
构建，运行并运行tada，它可以正常工作.
Build, run, and tada, it's working.
我不明白为什么几乎没有人谈论这种方法，该方法不需要在启动参数中添加任何内容，也不需要添加任何复杂的东西，并且它的工作要容易得多.
I can't understand why almost nobody talk about this method, which does not require adding anything in startup arguments, anything complex, and it works much much easier.
这有很大的不便之处吗?实际上，我想知道它是否还更好，因为它在编译时就编织了类，因此它将使用更少的系统资源?
Is there a big inconvenient at this ? In fact, I wonder if it's not even better, because it weave classes at compile time, so it will be using less system ressource ?
