java - 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 pretty-print 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>

输出是如预期的 pretty-print 。然后我继续进行配置，屏蔽为

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

输出也按预期标记。

无论如何，当我将这两者结合在一起时，它只做一件事，要么 pretty-print ，要么屏蔽。

<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>

它只进行屏蔽，但打印不漂亮。

<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>

它仅进行 pretty-print ，但未屏蔽。

如何将 PrettyPrintingJsonGeneratorDecorator 和 MaskingJsonGeneratorDecorator 组合在一起？可以请您帮忙指教吗？

使用 CompositeJsonGeneratorDecorator ，像这样:

<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>
