我有一个简单的带有slf4j的spring boot项目，我想修改日志，所以我在资源文件中创建了logback.xml
SELECT user.email,
COUNT(request.user_request_id) AS requests,
COUNT(action.lender_id) AS replies,
COUNT(request.user_request_id) + COUNT(action.lender_id) AS total
FROM request LEFT JOIN user ON user.id=request.user_request_id LEFT JOIN
action ON request.object_id=action.object_id
WHERE DATE_FORMAT(STR_TO_DATE(request.created_at, '%m-%d-%Y'), '%Y-%m')
= '2018-03'
OR DATE_FORMAT(STR_TO_DATE(action.created_at, '%m-%d-%Y'), '%Y-%m') =
'2018-03'
GROUP BY user.email
ORDER BY total desc;
但是它不起作用，仍然打印出较低级别的消息，而且没有“ TEST”就更重要。如果我添加到application.properties <configuration debug="false">
<appender name="STDOUT">
<encoder>
<pattern>TEST%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<root level="WARN">
<appender-ref ref="STDOUT" />
</root>
，那么一切都很好。我应该在某个地方添加logback.xml文件吗？
