如何解决 LogOutputStream 中文乱码问题？

This topic created in 1493 days ago, the information mentioned may be changed or developed.

不管是 org.apache.commons.exec 工具包，还是 org.zeroturnaround.exec 工具包，都会出现中文乱码问题，请问有办法解决吗？例子： org.apache.commons.exec 工具包的 demo：

package utils.exec; import cn.hutool.core.io.LineHandler; import lombok.NonNull; import lombok.extern.slf4j.Slf4j; import org.apache.commons.exec.*; import java.util.concurrent.TimeUnit; @Slf4j public class LocalCommandUtils { private static final long TIMEOUT = 1; private static final TimeUnit TIME_UNIT = TimeUnit.DAYS; public static String execCmd(String cmd) { return execCmd(cmd, line -> {}); } public static String execCmd(String cmd, LineHandler lineHandler) { return execCmd(cmd, lineHandler, TIMEOUT, TIME_UNIT); } public static String execCmd(String cmd, LineHandler lineHandler, @NonNull long timeout, @NonNull TimeUnit unit) { DefaultExecutor executor = new DefaultExecutor(); ExecuteWatchdog watchdog = new ExecuteWatchdog(unit.toMillis(timeout)); StringBuilder output = new StringBuilder(); try { CommandLine cmdLine = CommandLine.parse(cmd); executor.setWatchdog(watchdog); executor.setStreamHandler(new PumpStreamHandler(new LogOutputStream() { @Override protected void processLine(String line, int logLevel) { lineHandler.handle(line); output.append(output.length() > 0 ? "\n" : "").append(line); } })); executor.execute(cmdLine); log.info("exec command:[{}] output:[\n{}\n]", cmd, output); } catch (Exception e) { log.error("exec command:[{}] failed, output:[\n{}\n]", cmd, output, e); } return output.toString(); } public static void main(String[] args) { execCmd("ping 127.0.0.1", log::info); } }

org.zeroturnaround.exec 工具包的 demo：

package utils.ztexec; import cn.hutool.core.io.LineHandler; import lombok.NonNull; import lombok.extern.slf4j.Slf4j; import org.zeroturnaround.exec.ProcessExecutor; import org.zeroturnaround.exec.stream.LogOutputStream; import java.util.concurent.TimeUnit; @Slf4j public class LocalCommandUtils { private static final long TIMEOUT = 1; private static final TimeUnit TIME_UNIT = TimeUnit.DAYS; public static String execCmd(String cmd) { return execCmd(cmd, line -> {}); } public static String execCmd(String cmd, LineHandler lineHandler) { return execCmd(cmd, lineHandler, TIMEOUT, TIME_UNIT); } public static String execCmd(String cmd, LineHandler lineHandler, @NonNull long timeout, @NonNull TimeUnit unit) { StringBuilder output = new StringBuilder(); try { new ProcessExecutor() .commandSplit(cmd) .timeout(timeout, unit) .redirectOutput(new LogOutputStream() { @Override protected void processLine(String line) { lineHandler.handle(line); output.append(output.length() > 0 ? "\n" : "").append(line); } }) .execute(); log.info("exec command:[{}] output:[\n{}\n]", cmd, output); } catch (Exception e) { log.error("exec command:[{}] failed, output:[\n{}\n]", cmd, output, e); } return output.toString(); } public static void main(String[] args) { execCmd("ping 127.0.0.1", log::info); } }

研究了一下
这两个工具包在 github 上的代码，LogOutputStream 类都有设置 charset 的方法，但是是后来（ 2020 、2021 年）加入的功能

而 maven 仓库里的版本（一个停留在 2014 年，一个停留在 2020 年）都没有设置 charset 的方法

所以你可以

1. 寻找其他的工具包

2. 抄 github 上的代码，比如

2.1 新建一个类 LogOutputStream ,把

https://github.com/zeroturnaround/zt-exec/blob/master/src/main/java/org/zeroturnaround/exec/stream/LogOutputStream.java

里的代码复制过去

2.2 将 import org.zeroturnaround.exec.stream.LogOutputStream; 改成 import 你自己的 LogOutputStream

2.3 在 new LogOutputStream 时设置 charset ，new LogOutputStream() {}.setOutputCharset("GBK")
