如何在谷歌云功能中打印日语日志

Question

我使用logback在java中的谷歌云函数中打印日志。我想打印日本日志，但日志上都是奇怪的字符。如何在Java代码中打印日志

我的logback设置低于

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="jsonConsoleAppender"
class="ch.qos.logback.core.ConsoleAppender">
<encoder class="net.logstash.logback.encoder.LogstashEncoder">
<fieldNames>
<timestamp>[ignore]</timestamp>
<version>[ignore]</version>
<logger>[ignore]</logger>
<thread>[ignore]</thread>
<level>[ignore]</level>
<levelValue>[ignore]</levelValue>
</fieldNames>
<charset class="java.nio.charset.Charset">UTF-8</charset>
</encoder>
</appender>
<root level="INFO">
<appender-ref ref="jsonConsoleAppender"/>
</root>
</configuration>

我的代码打印日志

logger.info("処理開始:加工前処理", kv("severity", "NOTICE"));

日志是

{
"textPayload": "������������:���������������",
"insertId": "000000-47138e32-2a00-40ec-ad45-88c03dffc271",
"resource": {
"type": "cloud_function",
"labels": {
"project_id": "xxxxxx",
"region": "asia-northeast1",
"function_name": "function-2"
}
},
"timestamp": "2020-11-05T09:24:46.633Z",
"severity": "NOTICE",
"labels": {
"execution_id": "sa3kufvievy8"
},
"logName": "projects/xxxxxx/logs/cloudfunctions.googleapis.com%2Fcloud-functions",
"trace": "projects/xxxxxx/traces/17915c7ed95b6d275b424e95f1a5b94b",
"receiveTimestamp": "2020-11-05T09:24:56.671368622Z"
}

这里提到的GCP函数似乎不太支持Logback。所以我建议使用Java Logging API，它已经包含在云函数中。

一个示例代码是：

文件夹结构：

src->main-->java->com.>示例-->示例.java

pom.xml

示例.java

package com.example;
import com.google.cloud.functions.HttpFunction;
import com.google.cloud.functions.HttpRequest;
import com.google.cloud.functions.HttpResponse;
import java.io.BufferedWriter;
import java.io.IOException;
import java.util.logging.Logger;
public class Example implements HttpFunction {
private static final Logger logger = Logger.getLogger(Example.class.getName());
@Override
public void service(HttpRequest request, HttpResponse response)
throws IOException {
logger.info("処理開始:加工前処理");
BufferedWriter writer = response.getWriter();
writer.write("Messages successfully logged!");
}
}
