I use org.reflections
library to scan ClassPath and get classes. Here is my code:
Reflections ref = new Reflections();
Set<Class<? extends Service>> classes = new HashSet<>();
for (Class<? extends Service> subType : ref.getSubTypesOf(Service.class)) {
if (!Modifier.isAbstract(subType.getModifiers())) {
classes.add(subType);
}
}
But I faced a problem. It takes too much time. At the same time I can not set a package
new Reflections("my.pack");
because I want to save an ability to add Service classes in the future. How can I accelerate this process? Is it possible to exclude rt.jar
packs?
Use FilterBuilder
to exclude java
root package at least.
And it may help to specify SubTypesScanner
as that's what you're doing.
Reflections ref = new Reflections(new SubTypesScanner(),
new FilterBuilder().excludePackage("java"));
