URL: https://github.com/apache/skywalking/issues/7402
private static class Transformer implements AgentBuilder.Transformer {
private PluginFinder pluginFinder;
Transformer(PluginFinder pluginFinder) {
this.pluginFinder = pluginFinder;
}
@Override
public DynamicType.Builder<?> transform(final DynamicType.Builder<?>
builder,
final TypeDescription
typeDescription,
final ClassLoader
classLoader,
final JavaModule module) {
LoadedLibraryCollector.registerURLClassLoader(classLoader);
List<AbstractClassEnhancePluginDefine> pluginDefines =
pluginFinder.find(typeDescription);
if (pluginDefines.size() > 0) {
DynamicType.Builder<?> newBuilder = builder;
EnhanceContext context = new EnhanceContext();
for (AbstractClassEnhancePluginDefine define :
pluginDefines) {
DynamicType.Builder<?> possibleNewBuilder =
define.define(
typeDescription, newBuilder, classLoader,
context);
if (possibleNewBuilder != null) {
newBuilder = possibleNewBuilder;
}
}
if (context.isEnhanced()) {
LOGGER.debug("Finish the prepare stage for {}.",
typeDescription.getName());
}
return newBuilder;
}
LOGGER.debug("Matched class {}, but ignore by finding
mechanism.", typeDescription.getTypeName());
return builder;
}
}
When multiple plug-ins are hit, only the last one will take effect。
var newbuilder will be overwritten
How to make multiple plug-ins effective at the same time。
