Question

我创建了一个rest Web服务应用程序，该应用程序将通过查询数据库来获取特定属性的值。我在日志中间歇性地遇到以下错误： java.util.concurrent.ExecutionException：com.bestbuy.fews.exception.DBConnectionException

在大多数情况下，我也会获得所需的输出。

考虑到这可能是一个异步调用问题，我对logback.xml文件进行了更改，但还是没有运气。

logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <!--<include resource="org/springframework/boot/logging/logback/base.xml"/>-->
    <property resource="logback-${spring.profiles.active}.xml" />
    <!--<property name="LOG_PATH" value="${LogFilePath}" />-->
    <appender name="ROLLING_FILE_TIMEBASED_POLICY" class="ch.qos.logback.core.FileAppender">
        <file>${LogFilePath}/bestbuy_zrrbzr.log</file>
        <encoder>
            <pattern>%d:%-7p:%t: %-60m [%X{PrimaryKey}]: %-25c{1}%n
            </pattern>
        </encoder>
    </appender>

    <appender name="ASYNC" class="ch.qos.logback.classic.AsyncAppender" neverBlock="true">
        <appender-ref ref="ROLLING_FILE_TIMEBASED_POLICY" />
    </appender>

    <root level="INFO">
        <appender-ref ref="ASYNC" />
    </root>
</configuration>

    compile.exclude group:'ch.qos.logback'

DAO层代码

@Repository
interface EomsOrderEventRevisionRepository extends CrudRepository<EomsOrderEventRevision, String> {

    List<EomsOrderEventRevision> findAll()

    @Query("FROM EomsOrderEventRevision WHERE orderNo=:orderNo")
    EomsOrderEventRevision findByOrderNo(@Param("orderNo") String orderNo)
}

在日志中，我可以看到上述异常的计数接近如果我点击Web服务，则说20次50次。

谢谢您的帮助。
