WSO2 EI 6.1.1 - 在调用介体之后放置的每个API DEBUG级别日志语句，在相关日志文件中找不到

我需要记录特定API的DEBUG级别 . 我为示例API使用单独的日志文件：http://localhost:8280/test001 . 我已根据此要求使用每个API log4j属性（参考：https://docs.wso2.com/display/ESB490/Per-API+Logs+in+WSO2+ESB） . ISSUE: 在调用介体之后放置的DEBUG级别日志在文件中找不到 .

我的API：test.xml

<?xml version="1.0" encoding="UTF-8"?><api context="/test001" name="test" xmlns="http://ws.apache.org/ns/synapse">
<resource methods="GET"><inSequence>
       <log category="DEBUG" level="custom">
            <property name="DEBUG category" value="DEBUG LOG BEFORE CALL MEDIATOR"/>
        </log>

        <call>
            <endpoint>
                <http method="get" uri-template="http://localhost:8280/sample001"/>
            </endpoint>
        </call>
        <log category="DEBUG" level="custom">
            <property name="DEBUG category" value="DEBUG LOG AFTER CALL MEDIATOR"/>
        </log>
        <log level="custom">
            <property name="INFO  category" value="INFO LOG AFTER CALL MEDIATOR"/>
        </log>
        <payloadFactory media-type="xml">
            <format>
                <test>SUCCESS</test>
            </format>
            <args/>
        </payloadFactory>
        <loopback description="loop backing to out-sequence"/>
    </inSequence>
    <outSequence>
        <log category="DEBUG" level="custom">
            <property name="DEBUG category" value=" DBUG OUT SEQUENCE"/>
        </log>
        <log level="custom">
            <property name="INFO category" value="INFO OUT SEUENCE"/>
        </log>
        <send/>
    </outSequence>
    <faultSequence>
        <log category="DEBUG" level="custom">
            <property name="log DEBUG" value=" DBUG FAULT SEQUENCE"/>
        </log>
        <log level="custom">
            <property name="log DEBUG" value="INFO FAULT SEUENCE"/>
        </log>
    </faultSequence></resource></api>

我的log4j配置wso2ei-6.1.1 \ conf \ log4j.properties：

log4j.category.API_LOGGER.test =DEBUG,COMMON_API_APPENDER
log4j.appender.test.Append = true

log4j.appender.COMMON_API_APPENDER=org.apache.log4j.DailyRollingFileAppender
log4j.appender.COMMON_API_APPENDER.File=${carbon.home}/repository/logs/commonApi.log
log4j.appender.COMMON_API_APPENDER.datePattern='.'yyyy-MM-dd
log4j.appender.COMMON_API_APPENDER.layout=org.apache.log4j.PatternLayout
log4j.appender.COMMON_API_APPENDER.layout.ConversionPattern=%d{ISO8601} [%X{ip}-%X{host}] [%t] %5p %c{1} %m%n

Note: 在log4j.properties文件中未更改其他属性

commonApi.log:

2017-11-21 19:42:06,502 [-] [localhost-startStop-1]  INFO test Initializing API: test
2017-11-21 19:43:21,703 [-] [PassThroughMessageProcessor-1] DEBUG test DEBUG category = DEBUG LOG BEFORE CALL MEDIATOR
2017-11-21 19:43:22,021 [-] [PassThroughMessageProcessor-3] DEBUG test DEBUG category =  DBUG OUT SEQUENCE
2017-11-21 19:43:22,021 [-] [PassThroughMessageProcessor-3]  INFO test INFO category = INFO OUT SEUENCE

正如您在API代码中看到的，记录行：

DEBUG category = DEBUG LOG AFTER CALL MEDIATOR

commonApi.log文件中缺少 .

wso2carbon.log：

TID: [-1234] [] [2017-11-21 19:43:21,703] DEBUG {API_LOGGER.test} -  DEBUG category = DEBUG LOG BEFORE CALL MEDIATOR {API_LOGGER.test}

TID: [-1234] [] [2017-11-21 19:43:22,021] DEBUG {API_LOGGER.test} -  DEBUG category =  DBUG OUT SEQUENCE {API_LOGGER.test}
TID: [-1234] [] [2017-11-21 19:43:22,021]  INFO {org.apache.synapse.mediators.builtin.LogMediator} -  INFO category = INFO OUT SEUENCE {org.apache.synapse.mediators.builtin.LogMediator}
TID: [-1234] [] [2017-11-21 19:43:22,021]  INFO {API_LOGGER.test} -  INFO category = INFO OUT SEUENCE {API_LOGGER.test}

但是你可以看到信息日志行：

INFO  category = INFO LOG AFTER CALL MEDIATOR

在wso2carbon.log文件中（这确保在call-mediator之后执行） .

Note: 但是我可以保证以下事情：

• 在调用介体执行后写入的中介流（我可以在控制台中看到信息日志） .

• 调用介体成功响应值 .

• 如果没有API中的call-mediator，所有DEBUG日志行都在commonApi.log文件中 . （按预期工作）

• out-sequence DEBUG日志在文件中有任何方式 . （按预期工作）

提前致谢 . ！
