2. log4j2.xml檔案中的日誌配置(完整，可直接拷貝使用)

3. 配置application.properties
# 配置日誌輸出 spring.datasource.druid.filter.slf4j.enabled=true spring.datasource.druid.filter.slf4j.statement-create-after-log-enabled=false spring.datasource.druid.filter.slf4j.statement-close-after-log-enabled=false spring.datasource.druid.filter.slf4j.result-set-open-after-log-enabled=false spring.datasource.druid.filter.slf4j.result-set-close-after-log-enabled=false
4. 輸出日誌於druid-sql.log
