Spring Boot配置error日志发送至企业微信

1.创建 WeComAppender ，重写 AppenderBase 的 append 方法

import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.AppenderBase;
import cn.hutool.core.thread.ThreadUtil;
import com.alibaba.fastjson2.JSON;
import com.alibaba.fastjson2.JSONObject;import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.nio.charset.StandardCharsets;
import java.time.ZoneOffset;public class WeComAppender extends AppenderBase<ILoggingEvent> {@Overrideprotected void append(ILoggingEvent event) {try {// 按项目需求自定义拼装消息串，此处仅供参考StringBuilder sb = new StringBuilder();sb.append(event.getInstant().atOffset(ZoneOffset.ofHours(8)));sb.append(event);if (event.getThrowableProxy() != null) {sb.append(" ");sb.append(event.getThrowableProxy().getMessage());}// 异步请求，避免影响主线程ThreadUtil.execAsync(() -> sendHttpRequest(sb.toString()));} catch (Exception e) {}}/*** 发送请求* @param message*/public void sendHttpRequest(String message) {try {// 机器人 webhook 地址String webhookUrl = "https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=xxxxxxxxxxxxxxxxxxxxxxxxxx";URL url = new URL(webhookUrl);HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setRequestMethod("POST");connection.setRequestProperty("Content-Type", "application/json; utf-8");connection.setRequestProperty("Accept", "application/json");connection.setDoOutput(true);// 企微机器人固定的请求结构，详情请参考企微文档（钉钉的请参考钉钉文档）String jsonInputString = "{\"msgtype\": \"text\", \"text\": {\"content\": \"\"}}";JSONObject jsonObject = JSON.parseObject(jsonInputString);jsonObject.getJSONObject("text").put("content", message);try (OutputStream os = connection.getOutputStream()) {byte[] input = jsonObject.toString().getBytes(StandardCharsets.UTF_8);os.write(input, 0, input.length);}int responseCode = connection.getResponseCode();} catch (Exception e) {}}
}

2.配置 logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration><!-- WECOM：企微告警 --><!-- class 设置为 WeComAppender --><appender name="WECOM" class="com.hi.framework.logback.WeComLogbackAppender"><filter class="ch.qos.logback.classic.filter.ThresholdFilter"><!-- 日志等级为 ERROR --><level>ERROR</level></filter><encoder><pattern>%d{yyyy-MM-dd HH:mm:ss} %level [%thread] %logger{36} %msg%n</pattern></encoder></appender><root level="INFO"><appender-ref ref="WECOM" /></root></configuration>
