日志脱敏

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

    
    
     
     
    
    ...
    

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
