将 java 代理添加到 wildfly10.1.Final 服务器

Question

大家下午好，

我的问题：我似乎无法让 java 代理（ https://github.com/krpors/delver ）在 WildFly10.1.final 上工作

我在 tomcat 和 Wildfly 上部署了相同的演示 spring-boot 应用程序（战争）

将代理添加到 tomcat 非常简单（只需将 -javaagent:... 参数添加到 CATALINA_OPTS）tomcat 服务器启动并且代理完全按预期工作（列出 Z3501BB093D3638EDF 中指定包中的所有方法）代理的文件并跟踪该方法被调用了多少次以及持续了多长时间......）

当一切似乎与 tomcat 和我试图将 delver 代理添加到 WildFly 的代理完美无缺时，一切都开始 go 错误。

通过添加以下配置，我花了 4 天时间让疯狂的 10.1 服务器从代理开始：

set JAVA_OPTS= -Djava.util.logging.manager=org.jboss.logmanager.LogManager %JAVA_OPTS%
set JAVA_OPTS= -Xbootclasspath/p:%JBOSS_HOME%\modules\system\layers\base\org\jboss\logmanager\main\jboss-logmanager-2.0.4.Final.jar;%JBOSS_HOME%\modules\system\layers\base\org\jboss\log4j\logmanager\main\log4j-jboss-logmanager-1.1.2.Final.jar %JAVA_OPTS%
set JAVA_OPTS= -javaagent:D:\wildfly-10.1.0.Final\delver\delverJar0.jar=D:\wildfly-10.1.0.Final\delver\config.xml %JAVA_OPTS%

在standalone.bat 和这些

set "JAVA_OPTS= -Djboss.modules.system.pkgs=com.singularity,org.jboss.byteman,com.wily,com.wily.*,org.jboss.logmanager %JAVA_OPTS%"

在standalone.conf.bat

然后我遇到了两个问题

问题1

仅使用这些配置，部署在服务器上的战争将无法使用此堆栈跟踪（当我尝试访问 /Users 端点时为 404）

....

problem 2: I tried to solve the NoClassDefFoundError of the signature class (a class used inside the agent, see the GitHub link) by adding the agent jar as a global module in the server(created a module with the jar and added it as global )

现在应用程序（战争）正常工作，代理按预期显示指定 package 的所有方法，但它不显示调用该方法的次数或持续时间

这些是服务器控制台中的错误（不抛出异常）

....

似乎我以一种 hacky 的方式解决了问题 1，这导致了问题 2

而且我不禁觉得我需要在代理的源代码中更改一些内容以适应WildFly 10.1的class加载。 最后

ClassPool cp = ClassPool.getDefault();
cp.childFirstLookup = true;
cp.insertClassPath(new LoaderClassPath(loader));
 

            

我真的很感谢我在这个问题上被困一周的任何帮助:(

Answer 1

事实证明，我所要做的就是将 Signature package nl.omgwtfbbq.delver添加到 jboss 系统模块，以便所有应用程序都可以看到它

set "JAVA_OPTS= -Djboss.modules.system.pkgs=nl.omgwtfbbq.delver,org.jboss.byteman,org.jboss.logmanager %JAVA_OPTS%"
