如何在Java（System.out.println（））中阻止对标准输出的写入

Question

In Java, how to block code from writing to system out?
My app calls a 3rd party library that spams logs by issuing numerous System.out.println() calls.
I don't have legal rights to decompile and patch the library.
I'm running Websphere 8.5.x

Considered using System.setOut(PrintStream out) , but that will effect the entire process, while I only want to limit the effect to a single thread.

如果您可以确定要可靠地“静音”的线程（例如，按名称），则可以将setOut为自己的流，如果它们不是来自静音线程，则仅将调用委派给实际的System.out 。
