在spring boot应用程序中，Hibernate SQL语句不会使用log4j记录在单独的日志文件中

Question

我有一个部署在JBoss中的spring boot+Hibernate+Log4j的web应用程序。如果我们在application.properties中使用“spring.jpa.show-sql=true”，那么所有的hibernate sql查询都将记录在server.log中。根据Hibernate Log4j指令，我们需要将该属性变为false，以便按照Log4j配置将sql语句记录在单独的日志文件中。如果我们将其变为false，那么sql语句也不会记录在单独的日志文件中。除hibernate日志外，所有其他与应用程序相关的日志都记录在单独的日志文件中。请帮助解决此问题。

Below is the entry in application.properties file.
spring.jpa.show-sql = false
spring.jpa.open-in-view=false
spring.datasource.ucm.default-auto-commit=false
spring.jpa.properties.hibernate.enable_lazy_load_no_trans=true
spring.jpa.properties.hibernate.id.new_generator_mappings=false  
spring.jackson.serialization.fail-on-empty-beans=false

# SQL statements and parameters
log4j.logger.org.hibernate.SQL=debug
log4j.logger.org.hibernate.type.descriptor.sql=trace

您需要在应用程序中放置Log4j配置文件。然后在其中插入Logger标记：

<Configuration status="WARN" strict="true">
<Properties>
    <Property name="filename">logfile.log</Property>
</Properties>
<Appenders>
    <Appender type="Console" name="Console" target="SYSTEM_OUT">
        <Layout type="PatternLayout">
            <Pattern>%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n</Pattern>
        </Layout>
    </Appender>
    <Appender type="File" name="FileAppender" fileName="${filename}">
        <Layout type="PatternLayout">
            <Pattern>%d %p %C{1.} [%t] %m%n</Pattern>
        </Layout>
    </Appender>
</Appenders>
<Loggers>
    <Logger name="org.hibernate.SQL" level="debug" additivity="false">
        <AppenderRef ref="Console"/>
    </Logger>
    <Logger name="org.hibernate.type.descriptor.sql" level="trace" additivity="false">
        <AppenderRef ref="Console"/>
    </Logger>..........
