logback 日志脱敏

本文主要是介绍logback 日志脱敏，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

工具类

CustomLogbackPatternLayoutEncoder.java

import ch.qos.logback.classic.encoder.PatternLayoutEncoder;public class CustomLogbackPatternLayoutEncoder extends PatternLayoutEncoder {/*** 正则替换规则*/private LogbackReplaces replaces;/*** 使用自定义 MyLogbackPatternLayout 格式化输出*/@Overridepublic void start() {CustomPatternLayout patternLayout = new CustomPatternLayout(replaces);patternLayout.setContext(context);patternLayout.setPattern(this.getPattern());patternLayout.setOutputPatternAsHeader(outputPatternAsHeader);patternLayout.start();this.layout = patternLayout;started = true;}public LogbackReplaces getReplaces() {return replaces;}public void setReplaces(LogbackReplaces replaces) {this.replaces = replaces;}
}

CustomPatternLayout.java

import ch.qos.logback.classic.PatternLayout;
import ch.qos.logback.classic.spi.ILoggingEvent;
import lombok.extern.slf4j.Slf4j;@Slf4j
public class CustomPatternLayout extends PatternLayout {/*** 正则替换规则*/private final LogbackReplaces replaces;public CustomPatternLayout(LogbackReplaces replaces) {super();this.replaces = replaces;}/*** 格式化日志信息** @param event ILoggingEvent* @return 日志信息*/@Overridepublic String doLayout(ILoggingEvent event) {// 占位符填充String msg = super.doLayout(event);// 脱敏处理return this.buildSensitiveMsg(msg);}/*** 根据配置对日志进行脱敏** @param msg 消息* @return 脱敏后的日志信息*/public String buildSensitiveMsg(String msg) {if (this.replaces == null || this.replaces.getReplace() == null || this.replaces.getReplace().isEmpty()) {log.error("日志脱敏开启，但未配置脱敏规则，请检查配置后重试");return msg;}String sensitiveMsg = msg;for (RegexReplacement replace : this.replaces.getReplace()) {// 遍历脱敏正则 & 替换敏感数据sensitiveMsg = replace.format(sensitiveMsg);}return sensitiveMsg;}
}

RegexReplacement.java

import java.util.regex.Pattern;public class RegexReplacement {/*** 脱敏匹配正则*/private Pattern regex;/*** 替换正则*/private String replacement;/*** Perform the replacement.** @param msg The String to match against.* @return the replacement String.*/public String format(final String msg) {return regex.matcher(msg).replaceAll(replacement);}public Pattern getRegex() {return regex;}public void setRegex(String regex) {this.regex = Pattern.compile(regex);}public String getReplacement() {return replacement;}public void setReplacement(String replacement) {this.replacement = replacement;}
}

LogbackReplaces.java

import java.util.ArrayList;
import java.util.List;public class LogbackReplaces {/*** 脱敏正则列表*/private List<RegexReplacement> replace = new ArrayList<>();/*** 添加规则（因为replace类型是list，必须指定addReplace方法用以添加多个）** @param replacement replacement*/public void addReplace(RegexReplacement replacement) {replace.add(replacement);}public List<RegexReplacement> getReplace() {return replace;}public void setReplace(List<RegexReplacement> replace) {this.replace = replace;}
}
