如何将PrettyPrintingJsonGeneratorDecorator和MaskingJsonGeneratorDecorator结合在一起？

问题描述

我尝试配置logstash-logback-encoder版本6.4，以将漂亮的打印JSON打印为

<appender name="consoleAsJSON" class="ch.qos.logback.core.ConsoleAppender">
    <encoder class="net.logstash.logback.encoder.LogstashEncoder">
        <includeCallerData>true</includeCallerData>
        <jsonGeneratorDecorator class="net.logstash.logback.decorate.PrettyPrintingJsonGeneratorDecorator"/>
    </encoder>
</appender>

预期输出为pretty print。然后，我一步一步地进行掩膜配置

<appender name="consoleAsJSON" class="ch.qos.logback.core.ConsoleAppender">
    <encoder class="net.logstash.logback.encoder.LogstashEncoder">
        <includeCallerData>true</includeCallerData>
        <jsonGeneratorDecorator class="net.logstash.logback.mask.MaskingJsonGeneratorDecorator">
            <defaultMask>XXXX</defaultMask>
            <path>password</path>
        </jsonGeneratorDecorator>
    </encoder>
</appender>

输出也如预期的是marked。

无论如何，当我将两者结合在一起时，它只会做一件事，pretty print或masked。

<appender name="consoleAsJSON" class="ch.qos.logback.core.ConsoleAppender">
    <encoder class="net.logstash.logback.encoder.LogstashEncoder">
        <includeCallerData>true</includeCallerData>
        <jsonGeneratorDecorator class="net.logstash.logback.decorate.PrettyPrintingJsonGeneratorDecorator"/>
        <jsonGeneratorDecorator class="net.logstash.logback.mask.MaskingJsonGeneratorDecorator">
            <defaultMask>XXXX</defaultMask>
            <path>password</path>
        </jsonGeneratorDecorator>
    </encoder>
</appender>

仅执行masked，但执行not pretty print。

<appender name="consoleAsJSON" class="ch.qos.logback.core.ConsoleAppender">
    <encoder class="net.logstash.logback.encoder.LogstashEncoder">
        <includeCallerData>true</includeCallerData>
        <jsonGeneratorDecorator class="net.logstash.logback.mask.MaskingJsonGeneratorDecorator">
            <defaultMask>XXXX</defaultMask>
            <path>password</path>
        </jsonGeneratorDecorator>
        <jsonGeneratorDecorator class="net.logstash.logback.decorate.PrettyPrintingJsonGeneratorDecorator"/>
    </encoder>
</appender>

它只pretty print，但not masked。

如何将PrettyPrintingJsonGeneratorDecorator和MaskingJsonGeneratorDecorator结合在一起？您能帮忙提意见吗？

解决方法

使用CompositeJsonGeneratorDecorator，如下所示：

<appender name="consoleAsJSON" class="ch.qos.logback.core.ConsoleAppender">
    <encoder class="net.logstash.logback.encoder.LogstashEncoder">
        <includeCallerData>true</includeCallerData>
        <jsonGeneratorDecorator class="net.logstash.logback.decorate.CompositeJsonGeneratorDecorator">
            <decorator class="net.logstash.logback.decorate.PrettyPrintingJsonGeneratorDecorator"/>
            <decorator class="net.logstash.logback.mask.MaskingJsonGeneratorDecorator">
                <defaultMask>XXXX</defaultMask>
                <path>password</path>
            </decorator>
        </jsonGeneratorDecorator>
    </encoder>
</appender>
