如何将PrettyPrintingJsonGeneratorDecorator和MaskingJsonGeneratorDecorator结合在一起？

Question

我尝试将logstash-logback-encoder版本6.4配置为将漂亮的打印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>

输出和预期的一样是pretty print。然后，我开始使用掩蔽的方式进行配置。

<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>

输出也和预期的一样是marked。

无论如何，当我将这两者结合在一起时，它只做一件事，要么是pretty print，要么是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>

它只做masked，但是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>

它只做pretty print，但是not masked。

如何将PrettyPrintingJsonGeneratorDecorator和MaskingJsonGeneratorDecorator结合在一起？你能帮我提个建议吗？

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>
