您可以从Apache Commons https://commons.apache.org/proper/commons-
io/javadocs/api-2.4/org/apache/commons/io/output/NullOutputStream.html使用NullOutputStream
或者只是实现自己的
package mypackage;import java.io.OutputStream;import java.io.IOException;public class NullOutputStream extends OutputStream { public void write(int i) throws IOException { //do nothing }}
