Question

我正在尝试使用logging-channel-adapter记录入站消息。我有以下spring集成配置

<int:gateway service-interface="com.kipstor.events.EventGateway" default-request-channel="loggerChannel" />
<int:channel id="loggerChannel">
    <int:interceptors>
        <int:wire-tap channel="logger" />
    </int:interceptors>
</int:channel>
<int:logging-channel-adapter id="logger" logger-name="kipstorLog" level="INFO" log-full-message="true" />

我的log4j文件配置如下

log4j.appender.kipstorLog=org.apache.log4j.DailyRollingFileAppender
log4j.appender.kipstorLog.File=${catalina.home}/logs/kipstor.log
log4j.appender.kipstorLog.DatePattern='.'yyyy-MM-dd
log4j.appender.kipstorLog.MaxFileSize=5MB
log4j.appender.kipstorLog.MaxBackupIndex=10
log4j.appender.kipstorLog.layout=com.kipstor.kpp.util.CustomLogLayout
log4j.appender.kipstorLog.layout.ConversionPattern=%-5p %d{yyyy-MM-dd HH:mm:ss} %C{1}:%L - %m%n

但是，在发生异常后调用服务接口时

2018-02-23 11:17:17 ERROR SimpleAsyncUncaughtExceptionHandler:37 - Unexpected error occurred invoking async method 'public void com.kipstor.events.EventService.setEvent(java.lang.String,int,java.lang.String,java.lang.String[])'.

知道出了什么问题吗？

Answer 1

记录此消息后，将不再需要

所以，你根本不需要<wire-tap>。

这就足够了：

<int:gateway service-interface="com.kipstor.events.EventGateway" default-request-channel="logger" />

<int:logging-channel-adapter id="logger" logger-name="kipstorLog" level="INFO" log-full-message="true" />

我的意思是您的网关应该只向logger频道发送消息。

另一个你的问题值得一个单独的问题。它与这一主题无关。

Dispatcher在记录通道适配器上没有订户错误
