Question

我有一个关于此的问题，我要将回溯日志发送给兔子，我使用spring-rabbit，因为我需要用json格式发送数据，所以我使用了LoggingEventCompositeJsonEncoder，这里是我的配置

<appender name="AMQP" class="org.springframework.amqp.rabbit.logback.AmqpAppender">
    <!--<layout>-->
    <!--<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>-->
    <!--</layout>-->
    <encoder class="net.logstash.logback.encoder.LoggingEventCompositeJsonEncoder">
        <pattern>
            <pattern>
                { "level": "%level" }
            </pattern>
        </pattern>
    </encoder>
    <host>127.0.0.1</host>
    <port>5672</port>
    <username>guest</username>
    <password>guest</password>
    <routingKeyPattern>testroute</routingKeyPattern>
    <exchangeName>logs</exchangeName>

    <declareExchange>true</declareExchange>
    <generateId>true</generateId>
    <charset>UTF-8</charset>
    <durable>true</durable>
    <deliveryMode>PERSISTENT</deliveryMode>

</appender>

但是当我启动应用程序时，我收到如下错误：

 java.lang.IllegalStateException: Logback configuration error detected: ERROR in ch.qos.logback.core.joran.spi.Interpreter@16:88 - no applicable action for [encoder], current ElementPath  is [[configuration][appender][encoder]]

Answer 1

这是正确的org.springframework.amqp.rabbit.logback.AmqpAppender是AppenderBase扩展名，而不是支持OutputStreamAppender选项的encoder。

但是，我确信我们可以添加对它的支持，而不是原始msgBody.getBytes()已调用this.encoder.encode(event)。

关于此事的JIRA：https://jira.spring.io/browse/AMQP-760。

最新的spring-rabbit不支持编码器标签？
