log4j1.2.17的countingquietwriter的替换

如果您需要替换log4j 1.2.17中的CountingQuietWriter，您可以使用log4j 2.x版本中的CountingOutputStream和CountingQuietWriter替换它。这是因为log4j 1.x版本已经停止维护，建议升级到2.x版本。

以下是一个使用CountingOutputStream和CountingQuietWriter的例子：

import org.apache.logging.log4j.core.util.CountingQuietWriter;
import org.apache.logging.log4j.core.util.CountingOutputStream;

import java.io.IOException;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.nio.charset.Charset;

public class MyCountingQuietWriter extends CountingQuietWriter {

    public MyCountingQuietWriter(OutputStream os, OutputStreamWriter writer, Charset charset, CountingOutputStream cos) {
        super(os, writer, charset, cos);
    }

    public MyCountingQuietWriter(Writer writer, CountingOutputStream cos) {
        super(writer, cos);
    }

    @Override
    public void flush() {
        try {
            super.flush();
            getCountingOutputStream().flush();
        } catch (IOException e) {
            LOGGER.error("Failed to flush log stream", e);
        }
    }
}

// Usage:
OutputStream os = ...;
CountingOutputStream cos = new CountingOutputStream(os);
OutputStreamWriter writer = new OutputStreamWriter(cos, Charset.forName("UTF-8"));
MyCountingQuietWriter countingQuietWriter = new MyCountingQuietWriter(os, writer, Charset.forName("UTF-8"), cos);

上面的代码中，MyCountingQuietWriter继承自CountingQuietWriter并覆盖了flush方法，以将flush操作同步到CountingOutputStream中。您可以根据自己的需求进行修改。
