logback 日志脱敏

1. 继承MessageConverter，重写convert方法

public class SensitiveDataConverter extends MessageConverter {
    @Override
    public String convert(ILoggingEvent event) {
        // 获取原始日志
        String oriLogMsg = event.getFormattedMessage();
        //todo 获取脱敏后的日志
        String afterLogMsg = "";
        return afterLogMsg;
2. 修改xml配置文件，添加conversionRule标签，指定上面的SensitiveDataConverter类
<configuration>
    <!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径 -->
    <property name="LOG_HOME" value="./logs"/>
     <!--配置日志转换规则-->
    <conversionRule conversionWord="msg" converterClass="com.hfepay.common.log.config.SensitiveDataConverter"> </conversionRule>
</configuration>
log4j2 日志脱敏
1. 继承LogEventPatternConverter，重写format方法。加@Plugin 和 @ConverterKeys 注解
@Plugin(
        name = "SensitiveDataConverter",
        category = "Converter"
//自定义重写的属性
@ConverterKeys({"coverMsg"})
public class SensitiveDataConverter  extends LogEventPatternConverter {
    protected SensitiveDataConverter(String name, String style) {
        super(name, style);
    public static SensitiveDataConverter newInstance(String[] options) {
        return new SensitiveDataConverter("coverMsg", "coverMsg");
    @Override
    public void format(LogEvent logEvent, StringBuilder stringBuilder) {
        // 获取原始日志
        String oriLogMsg = logEvent.getMessage().getFormattedMessage();
         //todo 获取脱敏后的日志
        String afterLogMsg = "";
        stringBuilder.append(afterLogMsg);
2. 修改xml配置文件把原先PatternLayout标签里的pattern属性中的msg改成coverMsg
  <!--修改前的-->
  <PatternLayout charset="UTF-8"  pattern="%d{yyyy-MM-dd HH:mm:ss.SSS}|%-5level|%traceId|%thread|%logger:%line|%msg%n"/>
